But why would the Chimps suck the leaves rather than chew and gulp them? Newton and Nashida speculate that the drugs the Chimps are after may be inactivated by stomach acid. If so, absorbtion via the skin of the mouth might be the only way the drug could be taken in. Buccal administration of therapeutic drugs (sucked under the tongue or between the cheek and tongue) has been an 'accepted' medical practice since 1879. Only in this way can some therapeu­ tic drugs such as nitroglycer­ ine be readily absorbed into the circulatory system with­ out first having to survive inactivation by the acids of the gut or the detoxification processes of the liver. Stim­ ulants such as cocoa prod­ ucts, snuff and smokeless tobacco are also 'sucked in' in this way, knowledge of the mouth route having been shared by tropical forest peo­ ples for many generations. Newton and Nashida also noted another curious fact: the Chimps generally mouth­ sucked the leaves in the morning rather than in the afternoon when they nor­ mally foraged for food. Could it be that sought-after drugs were more concentrated in the leaves in the morning, or that overnighttheir blood lev­ els of this substance fell so low that it had to be replen­ ished first thing in the morn­ ing? Perhaps more likely, as Newton and ashida suggest, leaf-sucking is simply the equivalent of a stiff cup of black coffee in the morning. -Michael Archer University of NSW

672 AUSTRALIAN NATURAL HISTORY Where Did You Get That Tusk? Illegal trading in elephant ivory reached alarming pro­ portions in the last decade, seriously threatening the sur­ vival of the African Elephant (Loxodonta africana). The crisis culminated in an inter­ national ban on the ivory trade at the October 1989 meeting of CITES (Council for International Tr ade in Endangered Species). The ban was seen by many as the only way to save elephants from extinction. But will it? A blanket ban may only send black market prices skyrock­ eting and increase poaching pressure, as occurred with rhino horn. And, unlike the situation in East and central Africa, elephant populations are actually increasing in southern Africa. The issue is more complex than it appears at first. In southern Africa, ele­ phants have been better man­ aged and protected. In A new method has been devised that ical substrate of the region.

The most recent study was conducted in 1988 in Sabah by World Wide Fund for ature (Malaysia) scientist Dr Junaidi Payne (Ora11g­ utan co11servation in Sabah, WWFNM). It is based on aerial nest-count data and has put the Orang-utan popu­ lation in Sabah alone at between 10,000 and 20,000 individuals.

The highest population density was found to be in freshwater swamp forests, especially close to big rivers such as the Kinabatangan in eastern Sabah. There was a gradual decrease in numbers with distance from the coast, the numbers of Orangs found in mountainous inland areas being ten times fewer than those found on the coast.

Often the groups are further subdivided into smaller clusters. Although the groups are generally sta­ ble, the composition of clus­ ters making up each group varies continually, with the females (and sometimes their pups) shifting roosts once or twice a week, thus exposing themselves to new males with whom they sometimes mate. Adult females prefer to roost with certain other females, which are not necessarily relatives, and have the opportunity to form long, stable relationships with each other. At least two of the females studied were known to have roosted together for more than 12 years. Over the five-year period of Wilkinson's study, he and his assistants found that 7-30 per cent of vampires in a cluster fail to obtain a blood meal on any given night, and observed 110 instances of blood sharing by regurgita­ tion. Seventy per cent of instances were between mother and pup, while 30 per cent involved adult females feeding young other than their own, adult females feeding other adult females and, on two occasions, adult males feeding offspring.

678 AUSTRALIAN NATURAL HISTORY Did the Neanderthals Bury their Dead? The question as to whether or not the Neanderthals intentionally buried their dead is the subject of a recent paper by Robert Gar­ gett from the University of California at Berkeley (Curr. Anthrop. 30: 157-190; 1989). Earlier interpretations of the archaeological evidence from six Middle Palaeolithic sites (La Chapelle-aux-Saints, Le Moustier, La Ferrassie and Regourdou in France, Teshik­ Tash in the USSR, and Shani­ dar in Iraq) posited the association of human skeletal remains with the apparent remains of features such as flower offerings or circles of goat horns as evidence of intentional burial. If such interpretations are correct, then these sites constitute the earliest evidence of the human capacity for symbolic or ritualistic behaviour, an extremely significant adapta­ tion within the behavioural evolution of our species. Gargett, however, prefers to consider the evidence derived from these six Nean­ derthal sites within a geoar­ chaeological framework. His basic proposition is that the inference of mortuary ritual from archaeological deposits requires non-human agents to be ruled out. In other words ''It is not enough to say that humans could have produced a given deposit; it A nearly complete Neanderthal adult, gett is not without his critics. along with Frayer and must be shown that nature La Ferrassie I (France), in situ, 1909.

Through the window I could see the usual range of decorator antique bird prints, but one image seemed strangely unfam­ iliar to me. I entered the shop with some trepidation, as I noticed the price ticket on one armchair read £13,000. I edged my way toward this curious picture, which was titled on the mount "A Green Parrot". The picture was in fact a fine gouache on vellum, and was signed Moses Griffiths and dated 1772. However, the subject was not your ordinary green or 'Amazon' parrot but, as evident in the orange beak, was a lorikeet and, on closer examination, was likely a Rainbow Lorikeet (Tricho­ glossus Jzaematodus).

How had this obscure artist, Moses Griffiths (better known as Griffith), come to paint such a bird at the time of Cook's First Voyage? I decided to take the plunge and I bought the painting on the condition that it was genuine; however, I had to wait for fund to arrive from my bank in Australia. In the meantime, I began the detective work of piecing together the various threads of the story. First, ornithological experts at the British Museum ( atural History) agreed the portrait was indeed of Trichoglossus haematodus molucca11us or the Rainbow Lorikeet found along the eastern coast of Australia.

Vai said this was a insipida) is a close relative of true nutmeg (M. fragrans), and was used as a nutmeg substitute in Queensland, although it is less aromatic (hence the name insipida). Similarly, one of our native cinnamons (Cinnamomum oliv­ eri) has been used as a substitute for traditional cinnamon (C. verum). Australia also has plants in the same genus as pepper, turmeric and lemon grass. The culinary potential of these plants has been almost completely ignored, despite the current fascination with wild foods. The native lemon grasses (Cymbo­ pogon species) interest me especially. There are no less than ten native species, occurring across northern and outback Australia in rocky and sandy soils. They vary in form from small slender tussocks to large coarse clumps, but all have aromatic leaves and stems, with a lemon or ginger scent. When I first learned about these grasses I was curious about their culinary potential. But I have been able to find only two accounts of their use as flavourings, both by Aborigines. Vai Stanton, an interesting and knowledge­ able Koongarukunj woman originally from Katherine, orthern Te rritory, told me her parents used to flavour beef with a wild lemon grass. They also burnt bundles of this grass to ward off Among the boulders of the Devil's Marbles in central Australia, lemon-scented Grass is one of the most common plants.

698 AUSTRALIAN NATURAL HISTORY species, live at Coconut Beach. This afternoon, I'll be lucky to catch a dozen. But why travel all the way from Berkeley, California, to spend weeks prowling the reefs of Lizard Island in search of this elusive quarry? Beyond the aesthetic pleasures of such research (and the relief from classrooms, telephones and endless committee meetings) lies the growing satisfaction and occasional excitement of unravel­ ling the biology of one of the most remarkable groups of animals I know. Studying the morphology, behaviour and ecology of stomatopods has helped me understand the interdependence of each in the evolution of the whole. TOMATOl'OUS AKE A SMALL HUT DIVEi/SE Sgroup of marine predators with about 400 species representing 14 families and 74 genera. Only distantly related to more familiar crabs and prawns, the stomatopod lineage split off from other crustaceans 400 million years ago. Most species are restricted to shallow tropical and subtropical seas. Stomato­ pods can be found in just about any subtidal habitat surrounding Lizard Island. Several species live in cavities in live or dead coral, coralline algae or rock. Others excavate burrows in sand or mud. A few occur only at depths greater than 20 metres, while some live well into the intertidal zone. After several visits to the Lizard Island Research Station, I have learned where each of the 21 species I have collected around the island might be found. And each new expedition yields at least one or two additional species, often new to science. The most u111que teature ot stomato­ pods is their pair of enlarged raptorial appendages carried folded beneath the head. They are analogous to the forelimbs used by praying mantises to seize prey and it is this similarity that gives stomatopods their common name of mantis shrimp. One difference is that mantids strike overhand, trapping their prey from above, useful for catching insects attempting to take flight. Stomatopods strike underhand, hitting their victims from below where prey such as prawns and fish are more Comparison of the raptorial appendages (or dactyls) of a spearing stomatopod (top) with that of a smasher vulnerable.

Note the broad peanut-shaped eye and bright eye shine, typical of nocturnal spearing stomatopods. which can be used for range-finding. If both eyes are brought to bear on a tar�et, the stomatopod has 'hexnocular' v1s1on. In some species, and particularly in spearers such as lysiosquilla that must hit moving prey at a distance, the eye has become broad and peanut-shaped, moving the pseudopupils further apart. This increases the parallax (the apparent change in the position of an object resulting from the change in the position from which it is viewed) and Gonodactylusplatysoma is one of the most common stomatopods encountered throughout the lndo-Pacific. thereby increases the ability to This eight-centimetre smasher can be seen on the reef flat darting from coral head to coral head during determine the distance to an object. low tide.

VO LU M E 2 3 N U M BE R 9 , WI N TE R 1991 701 gather light. The few species studied to date possess only a single visual pigment, which would prevent them from distinguishing colours. Most smashers, on the other hand, live in clear, shallow water and are active during the day, making frequent forays from their cavities to hunt. Because of their colourful body markings, I have suspected that at least some of these stomatopods use colour vision in their interactions with one another. Recently, Dr Tom Cronin of the University of Maryland and Mr Justin Marshall of the University of Sussex have shown that the eyes of the major group of stomatopods containing most smasher species, the gonodactyloids, appear capable of sophisticated colour analysis. But even in gonodactyloid eyes, the ommatidia of the dorsal and ventral hemispheres contain only one visual pigment and are similar to those of other stomatopods. However, the central band in the gonodactyloids is more complex. In species without colour vision, the central band contains only two rows of rather ordinary crustacean ommatidia, but the central bands of groups that appear capable of colour discrimination have six rows of specialised ommatidia, each serving a different function. Rows 5 and 6 contain a single visual pigment and have structures that appear adapted for detecting polarised light, each sensitive to perpendicular planes of polarisation. For what purpose, we can only speculate, but a possibility is homing. Stomatopods that travel far from their cavities, as many smashers do, might use polarisation cues to determine which direction is home, just as Honeybees use the polarised sky to Central band of a typical gonodadyloid eye, comprising six rows (I�) of specialised ommatidia.

Each ommatidium is also apparently sensitive to ultraviolet light (although shown here peak sensitivity to wavelengths of light as darkest purple). (Adapted from Cronin and Marshall 1989.) ranging from violet to green. In addition, in rows 2 and 3, the receptor cells of each tier are capped by a coloured filter that further tunes the sensitivity of the system. The filters in row 2 are mostly yellow and orange, while those in row 3 may be red, purple or blue. The outer tier of each ommatidium is sensitive to shorter wavelengths than is the inner one, and the outer filters pass shorter wave­ lengths than do the deep filters. The result is fours pairs of receptors, each with a pair of narrow spectral sensitivity curves separated by 50 to 75 nanometres (thousand-millionths of a metre) that cover the spectrum from the near ultraviolet to red. Further­ more, physiological tests have shown that these stomatopods also have another visual pigment in the central Scanning Electron Micrograph of the eye of a juvenile Gonodacty/us.

702 AUSTRALIAN NATURAL HISTORY The eyes of gonodactyloid stomatopods have colour filters that increase the animal's sensitivity to colour. These occur in rows 2 (yellow) and 3 (purple) of the central band of ommatidia. With at least ten visual pigments plus several colour filters, this system is vastly more complex than our own colour vision based on three visual pigments, or even that of some birds, turtles and fish that may have up to five visual pigments and one coloured filter. But why? Prey and predator detec­ tion while moving through their complex visual worlds probably accounts for part of the reason, but I suspect that the rest of the answer concerns the evolution of the smashing raptorial appendage and the danger it poses to other stomatopods.

Having spent the better part of a year as a dormant immature grub in an underground brood cell, the female has chosen today to metamorphose into an adult and to gnaw her way up to the surface. As the female pulls herself out of the ground, the first male lunges to meet her just as a bevy of rival males rushes to the spot. In an instant. a tumbling bundle of males forms around the female, whirring and buzzing and biting, as the males struggle to carry off the female. Finally, out of the melee emerges a pair, the male mounted on the female, which seems none the worse for the tussle. They half-fly, half-run across the ground away from the mob of buzzing males that has already begun to break up, now that the female has gone. Once well removed from the others, the pair perches on the ground and copulates briefly before the male releases his partner. She flies away, no longer receptive to ardent male suitors now that she has mated. Instead she will devote the rest of her life to building a nest with underground chambers, which she will stock with provisions from the blossoms of a poverty bush (Eremophila /aani). Her emergence, along with that of thousands of other females, has been timed beautifully to coincide with the flowering season of this species of poverty bush, which grows in abun­ dance on these hard plains. Each provisioned cell within her nest receives an egg. To fertilise an egg before laying it, the female uses sperm from the supply she has stored in a special organ (the spermatheca) after her first and only mating. The offspring that result will spend a year underground in the red soil of Western Australia before emerging for a brief round of mating and nesting when the poverty bushes bloom again. ow the behaviour of Dawson's Burrowing Bees is full of remarkable features-especially the male's ability to find virgin females that are about to emerge and the male's readiness to

Instead, each adult female anthophorid usually works entirely on her own to find the food resources with which to provision her larval offspring. The diversity of female behaviour that exists within the Anthophoridae is modest compared to the variety of male mating tactics. There are many species whose males non-aggressively patrol the pollen- and nectar-producing flow­ ers that nesting females visit to gather provisions for their larval offspring. When a male of these bees spots a female in his wanderings, he pounces upon her and attempts to mate. In other species, however, males set up little territories by a particularly rich patch of flowers, driving rivals away in order to be the only male present, able and willing when sexually receptive females come foraging. Counterintuitive though it may be, still other anthophorid males defend hovering stations at plants without flowers, particularly at trees or bushes growing on prominent hilltops or at other conspicuous landmarks. In these species, females search males out, rather than the other way round. The list of anthophorid mate-finding strategies also includes the tactic of searching for emergence ites. as is exhibited by Dawson's Burrowing Bee and the Digger Bee. But in most of the bees in this category, males pursue females only after their potential mates have come out of the ground rather than locating them prior to their emergence. Why should Dawson's Burrowing Bee and the Digger Bee be such similar exceptions to the rule? The two species are members of the same family and therefore may have simply inherited the fundamental mat- A male Digger Bee digs down to meet a virgin adult female that is burrowing up to the surface.

revealed a large and hooded claw, which was doubtless used in killing, and it is now universally considered as a specialised leopard-like carnivore. The ecology of the extinct Giant Rat­ kangaroo is even more enigmatic. About the size of a female Eastern Grey Kangaroo, it had a dentition similar to that of much smaller insectivores. It existed throughout eastern Australia during the last ice age, even in areas of grass steppe. It may well have been omnivorous, eating plant matter and scavenging. opportunistically taking bird eggs and small vertebrates. In the entire Australasian region, therefore. there was only one mammal species filling each of the broad ecological niches of dog-like, cat-like, civet-like and scavenging species. Just how unusual this situation is in a worldwide context is best shown by referring to the table in which the larger carnivores of Meganesia. East Africa, Thailand and the United States of America (chosen as representative of their region because good references were available) are sorted according to their broad ecological niches. (The The undersides of two skulls and a lower jaw of the extinct Marsupial Lion. Note the greatly enlarged category ·civet-like and other' 1s a premolars used to slice through flesh. catch-all for unusual carnivores, from

724 AUSTRALIAN NATURAL HISTORY otters to civets and bears. The ecological niche of the Giant Rat­ kangaroo remains unknown but it was clearly different to the others. For convenience it is listed in this category.) It is obvious from this list that Meganesia is grossly depauperate in carnivores. Generally the cat-like and dog-like niches are subdivided accord­ ing to size, prey type and habitat, allowing many species to coexist. There are also large numbers of specialised or unusual species (the catch-all cat­ egory). Indeed Thailand, with 24 species, dwarfs Meganesia with its four or five, even though its land area is less than one-fifteenth the size. Even expressed as a ratio of the number of carnivores in excess of five kilograms to herbivores in excess of ten kilograms, the difference still holds. For example, East Africa has around 77 herbivorous or insectivorous mammal species that weigh over ten kilograms (there may be additional species that became extinct in the Pleistocene, bringing the number to approximately 80 species). This gives a ratio of 0. 26, or just over one carnivorefor every four herbivores. For Australia the ratio is 0. 07, or one carnivore for every 15 herbivores! IOLOCISTS HAVE LO G SPECULATED ON the cause of this great imbalance in theB Meganesian mammal fauna. One idea that has been discussed from time to time is that marsupials, for some reason, have found it difficult to evolve into truly predatory species, perhaps 'oecause of their relatively small brains (placental carnivores only recently-in the last 40,000 years-reached Aus­ tralia). However, a quick look at the fossil record of South America dis­ proves this hypothesis, since many species of dog-like marsupials of the subfamily Borhyaeninae evolved there during the Tertiary. These ranged in size from that of a bear to that of a civet. A second, even more remarkable subfamily of South American carnivor­ ous marsupials, the Thylacosmylinae, evolved into animals resembling sabre­

tooth cats and were probably capable of The possibly carnivorous Giant Rat-kangaroo, which inhabited eastern Australia until 20,000-40,000years killing the largest of prey.

There are around 77 million hectares of arable land (ten per cent of the total Australian land area) but most of this is extremely marginal when compared with that overseas. Other indications come from Australia's plants, which have developed a wide variety of strategies (including slow average growth rates) to cope with the nutrient-poor environment. A second important factor has also recently been recognised. This is the impact of the El Nino-Southern Oscillation (E SO) cycle, which influences rainfall with a periodicity of roughly a decade. In some years (such as 1990) Australia receives high rainfall and thus experien_ces peak productivity. However, 111 El N1110 years rainfall is reduced and prolonged droughts are frequent. It is now known The landmass of Meganesia as it existed during ice that Australia is unique in the degree to ages when sea-level was up to 160 metres lower which the cycle influences the entire than at present.

These factors may well have given them an advantage over mammal predators in resource-poor Meganesia. Armed with this knowledge we can look back over the Australian fossil record to investigate if there were periods when Australia supported a greater number of mammalian carni­ vores, thus indicating a significantly greater biological productivity. Unfor­ tunately much relevant data remain unpublished but it appears possible that at least two species of dog-like carnivores (thylacinids) coexisted at Riversleigh (north-western Queens­ land) during the Miocene, around 20 million years ago: and it is known that both a large and small species of marsupial lion coexisted in eastern ew South Wales in the Pliocene period, five lo two million years ago. Even given this slight increase in carnivore diversity in earlier times, the number does not compare with those that have existed on every other continent (except Antarctica) throughout the age of mammals. It seems possible that Meganesia has. at least for the past 20 million years. been a resource-poor land. and that it has suffered perhaps a further decrease over the past two million years. FINAi.

to a decrease in carnivore diversity rather than an increase. This is because it apparently drove both the Thylacine and Tasmanian Devil to extinction on mainland Australia, so it too is a replacement, not an addition. The case of the fox is intriguing, for it has been extraordinarily successful since its introduction in the 1850s. Its diet, like that of humans, is remarkably broad. It can survive on insects and berries if no vertebrate prey are available, and it can also kill animals as large as young Euros (weighing around 20 kilograms). A large part of the fox's success may be due to the abundance of rabbits in Australia. The rabbit itself may only be so successful because of the prior extinction of many species, which left abundant niches vacant in the Australian landscape. Thus the fox and rabbit may be utilising production that otherwise would have fuelled a whole megafauna. Furthermore, the smaller marsupial carnivores (quolls) have declined wherever foxes are present. Overall, I feel that the success of these introduced carnivores does not detract from the idea that Meganesia is generally a hostile environment for mammalian carnivores because, by and large, they have been replacements for the few existing species. The hypothesis developed here is a useful one in that it allows us to examine many other questions. Could it be, for example, that our herbivores are (and were) especially susceptible to predation by placental carnivores because, before people arrived, they only had to deal with 'thick-witted' reptiles? Additionally, does the hypoth­ esis tell us anything about the relative abundance of species of megafauna? Are there other resource-limited places, such as islands, where reptiles have become the dominant predators (Komodo Island and its dragons, and New Caledonia and its newly discovered extinct large varanid come to mind)? Whatever the case, the mystery of the Meganesian meat-eaters reminds us again of what a strange corner of the wo rld we live in, and just how little we understand it. •

734 AUSTRALIAN NATURAL HISTORY developed condition, it must climb into the pouch and open its mouth to grab a teat. But at this stage the dentary and squamosal bones, destined to form the bandicoot's normal jaw joint, have only just begun to develop. So how does it open its mouth? As in all embryonic mammals including ourselves, immediately behind the developing jaw, at the junction of the jaw and the skull, are two relatively large bones. Developing precisely where a jaw hinge ought to be, they are the articular (soon to be the hammer) and quadrate (soon to be the anvil), ready, willing and able to hinge the lower jaw as it opens for the first time; borrowing, as it were, from its reptilian past to ensure its mammalian future. Once teated, the bandicoot baby shuts up and sucks for another 50 days. Then, when it opens its mouth for the second time in its life, to release the teat that brought it this far, it does so as a bona tide mammal, using the now well-developed dentary and squamosal jaw joint. Perceiving four-dimensional patterns in living creatures and discovering their historical and developmental causes is one of the most intensely pleasurable experiences a biologist can have. The intertwined evidences from the fossil record, anatomy and embryology, which converge to provide understanding about the nature of the teensy weensy middle ear bones of mammals, are to biologists what the telescopic visions of the universe were to Galileo.

So the passage of genes from ancestors to descendants is considered ·vertical gene flow·, although thi phrase is rarely used. Horizontal gene flow involves the transfer of genes from one individual to another outside the parent-offspring relationship. It has precious little inrnlvement with sex, at least as we know it.
