The spermatophores show similarities with those described for other members of the family Diogenidae (especially the genus Cliba narius), and are composed of three major regions: a sperm-filled, circular flat ampulla; a columnar stalk; and a pedestal. The morphology and size of the spermatophore of L. loxochelis, along with a distinguishable constriction or neck that penetrates almost halfway into the base of the ampulla, are characteristic of this species. The size of the spermatophore is related to hermit crab size. Direct relationships were found between the spermatophore ampulla width, total length, and peduncle length with carapace length of the hermit crab. These morphological characteristics and size of the spermatophore ofL. -

For personal use only. factors that influence the outcome of plant–microorganism interactions, the spatial and temporal dynamics of these factors, and the diversity of any given pathogen makes it increasingly challenging to define simple, all-purpose rules to circumscribe the host range of a pathogen. For bacteria, fungi, oomycetes, and viruses, we illustrate that host range is often an overlapping continuum—more so than the separation of discrete pathotypes—and that host jumps are common. By setting the mechanisms of plant–pathogen in- teractions into the scales of contemporary land use and Earth history, we propose a framework to assess the frontiers of host range for practical appli- cations and research on pathogen evolution. -

Day 1 pre-tour extension Friday 14th February The group members were on an overnight flight to Bogotá. Day 2 pre-tour extension Saturday 15th February The pre-tour group’s direct flight from LHR touched down in Bogotá early this morning, and everyone soon met up with the friendly ground team at the arrivals’ hall. With little traffic on the roads at this time, we easily slipped out of the city on the opposite side of town and headed up into the beautiful cloud-forested slopes of the eastern Andes. A delicious breakfast was enjoyed (the freshly prepared arepas went down particularly well!) as misty rain fell. Thankfully, by the time we hit our first birding spot the skies had cleared, and the first rays of sunshine brightened up the day and the bird activity started to buzz. The group enjoyed a selection of nice flowerpiecers (Masked, Bluish, White-sided and Black), while the smart Slaty-backed Chat-Tyrant and the striking Scarlet- bellied Mountain Tanager both showed at close range. There were plenty of hummingbirds around, including goodies like Tyrian Metaltail, Glowing Puffleg and one of the regional endemics, Amethyst-throated Sunangel. -
The Dusky Kob Argyrosomus Japonicus
S. Afr. J. mar. Sci. 18: 249–264 1997 249 FEEDING ECOLOGY OF SOUTH AFRICAN ARGYROSOMUS JAPONICUS (PISCES: SCIAENIDAE), WITH EMPHASIS ON THE EASTERN CAPE SURF ZONE M. H. GRIFFITHS* The feeding ecology of dusky kob A. japonicus was determined from the stomach contents of line-caught specimens from several estuarine, surf zone and nearshore localities in KwaZulu-Natal and the Eastern and Western Cape. The accuracy of dietary descriptions for dusky kob depends on sample size, sampling frequency and sampling period. A. japonicus in the marine environment fed on a wide variety of organisms, including ben- thic, epibenthic and pelagic crustaceans, cephalopods and teleosts. Teleosts were by far the most important taxon, but at the species level the principal items varied with environment. There was a general increase in the importance of squid and teleosts, and a concomitant decrease in the importance of crustacea with growth. Feeding frequency and intensity were generally higher in the surf zone than in nearby estuaries, which demon- strates the importance of the former as a foraging area. Dusky kob from surf zones with mixed reef/sand sub- strata fed more regularly, ate larger meals and consumed a wider variety of organisms (38 v. 28) than did those from predominantly sandy substrata. It is concluded that A. japonicus is a top predator that influences the pelagic and demersal food chains of estuaries, the surf zone and the nearshore environment, and that its currently de- pleted condition has almost certainly had an impact on the foodwebs of all three of those habitats. The dusky kob Argyrosomus japonicus is a large Dudley 1991a, b, Smale 1991, Dudley and Cliff sciaenid (maximum size 1.8 m and 75 kg) which 1993), the relative importance of these two habitats as occurs in both northern and southern hemispheres. -
