Beach Treasures
BEACH TREASURES – HAVE YOU SEEN THEM? … Peter Crowcroft, Eco-Logic Education and Environment Services … Drawings by Kaye Traynor As the weather warms, and walking on the beach becomes much more appealing, keep a lookout along the high tide line for these two interesting, but rarely seen, beach treasures. Argonauta nodosa: Known as the Knobby Argonaut, or often, mistakenly, called the Paper Nautilus, this animal is actually a species of octopus that freely swims in the open ocean, in what is known as the pelagic zone – i.e. neither close to the bottom nor near the shore. It is in the family Argonautidae. Females of this species grow significantly larger than males, and secrete their paper-thin egg casing, that is such a rare and special find along our southern Australian beaches. To find a specimen in pristine condition, without any breakages, is considered by many as the pinnacle of beach combing fortune. Although this fragile structure acts as a shell, protecting and housing the female argonaut, it is unlike other cephalopod, true shells, and is regarded as an evolutionary novelty, unique to this family. The egg casing is typically around 150 mm in length, though some extraordinary Argonauta nodosa Knobby Argonaut specimens at 250 mm, or even larger, are known to grace some mantelpieces. Due to the radical dimorphism between male and females, not much was known about male Argonauts until relatively recently. Unlike the females, they do not secrete and live in an egg case, they reach only a fraction of the female size, and live a much shorter lifespans – only mating once, unlike the females that produce numerous broods of eggs throughout their lives. -

E-mails: [email protected], [email protected] 2Corresponding author Abstract Diadema setosum (Leske, 1778), a widespread tropical echinoid and key herbivore in shallow water environments is cur- rently expanding in the Mediterranean Sea. It was introduced by unknown means and first observed in southern Turkey in 2006. From there it spread eastwards to Lebanon (2009) and westwards to the Aegean Sea (2014). Since late 2016 spo- radic sightings of black, long-spined sea urchins were reported by recreational divers from rock reefs off the Israeli coast. Numerous attempts to verify these records failed; neither did the BioBlitz Israel task force encounter any D. setosum in their campaigns. Finally, a single adult specimen was observed on June 17, 2017 in a deep rock crevice at 3.5 m depth at Gordon Beach, Tel Aviv. Although the specimen could not be recovered, spine fragments sampled were enough to genet- ically verify the visual underwater identification based on morphology. Sequences of COI, ATP8-Lysine, and the mito- chondrial Control Region of the Israel specimen are identical to those of the specimen collected in 2006 in Turkey, unambiguously assigning the specimen to D. -
Comparative Phylogeography As an Integrative Approach to Historical Biogeography
Journal of Biogeography, 28, 819±825 Comparative phylogeography as an integrative approach to historical biogeography ABSTRACT GUEST EDITORIAL Phylogeography has become a powerful approach for elucidating contemporary geographical patterns of evolutionary subdivision within species and species complexes. A recent extension of this approach is the comparison of phylogeographic patterns of multiple co-distributed taxonomic groups, or `comparative phylogeography.' Recent comparative phylogeographic studies have revealed pervasive and previously unrecognized biogeographic patterns which suggest that vicariance has played a more important role in the historical development of modern biotic assemblages than current taxonomy would indicate. Despite the utility of comparative phylogeography for uncovering such `cryptic vicariance', this approach has yet to be embraced by some researchers as a valuable complement to other approaches to historical biogeography. We address here some of the common misconceptions surrounding comparative phylogeography, provide an example of this approach based on the boreal mammal fauna of North America, and argue that together with other approaches, comparative phylogeography can contribute importantly to our understanding of the relationship between earth history and biotic diversi®cation. Keywords Area cladistics, comparative phylogeography, historical biogeography, vicariance. INTRODUCTION In a recent guest editorial Humphries (2000) presented an overview of historical biogeography. He concentrated largely on comparisons -

The Shallow-Water Macro Echinoderm Fauna of Nha Trang Bay (Vietnam): Status at the Onset of Protection of Habitats
The Shallow-water Macro Echinoderm Fauna of Nha Trang Bay (Vietnam): Status at the Onset of Protection of Habitats Master Thesis in Marine Biology for the degree Candidatus scientiarum Øyvind Fjukmoen Institute of Biology University of Bergen Spring 2006 ABSTRACT Hon Mun Marine Protected Area, in Nha Trang Bay (South Central Vietnam) was established in 2002. In the first period after protection had been initiated, a baseline survey on the shallow-water macro echinoderm fauna was conducted. Reefs in the bay were surveyed by transects and free-swimming observations, over an area of about 6450 m2. The main area focused on was the core zone of the marine reserve, where fishing and harvesting is prohibited. Abundances, body sizes, microhabitat preferences and spatial patterns in distribution for the different species were analysed. A total of 32 different macro echinoderm taxa was recorded (7 crinoids, 9 asteroids, 7 echinoids and 8 holothurians). Reefs surveyed were dominated by the locally very abundant and widely distributed sea urchin Diadema setosum (Leske), which comprised 74% of all specimens counted. Most species were low in numbers, and showed high degree of small- scale spatial variation. Commercially valuable species of sea cucumbers and sea urchins were nearly absent from the reefs. Species inventories of shallow-water asteroids and echinoids in the South China Sea were analysed. The results indicate that the waters of Nha Trang have echinoid and asteroid fauna quite similar to that of the Spratly archipelago. Comparable pristine areas can thus be expected to be found around the offshore islands in the open parts of the South China Sea. -

Molecular Phylogenetics: Principles and Practice
REVIEWS STUDY DESIGNS Molecular phylogenetics: principles and practice Ziheng Yang1,2 and Bruce Rannala1,3 Abstract | Phylogenies are important for addressing various biological questions such as relationships among species or genes, the origin and spread of viral infection and the demographic changes and migration patterns of species. The advancement of sequencing technologies has taken phylogenetic analysis to a new height. Phylogenies have permeated nearly every branch of biology, and the plethora of phylogenetic methods and software packages that are now available may seem daunting to an experimental biologist. Here, we review the major methods of phylogenetic analysis, including parsimony, distance, likelihood and Bayesian methods. We discuss their strengths and weaknesses and provide guidance for their use. statistical Systematics Before the advent of DNA sequencing technologies, phylogenetics, creating the emerging field of 2,18,19 The inference of phylogenetic phylogenetic trees were used almost exclusively to phylogeography.

NMFS proposes to implement the specifications for fishing year 2015, 2016, 2017, and 2018 separately prior to each fishing year. The specifications pertain to ACLs for coral reef ecosystem fisheries in the Exclusive Economic Zone (EEZ or federal waters; generally 3-200 nautical miles or nm) around American Samoa, the Commonwealth of the Northern Mariana Islands (CNMI), Guam, and Hawaii, and a post-season AM to correct the overage of an ACL if it occurs. Because of the large number of individual coral reef ecosystem management unit species (CREMUS) in each island area, individual species were aggregated into higher taxonomic groups, generally at the family level. -

The proximate composition and cytotoxicity of the combined spines, tests and gonads of the selected three species of sea urchin namely: Diadema setusom, Tripnuestes gratilla and Astropyga radiata greatly vary in their proximate composition. Specifically, the three-sample species are potential source of nutrients and minerals. The cytotoxic activity using brine shrimp lethality test differ in selected sea urchins. The test for cytotoxicity showed that LC50 is ˃1000 ppm which is non-toxic. The results confirmed samples non-toxicity since the species are edible and local folks eat and sell them as source of livelihood. Preservation and conservation of sea urchin species are necessary for it is one of the most significant marine invertebrates used as bioindicator and as source for livelihood and commercialization. * Corresponding Author: Genevieve U Garcia [email protected] 350 Garcia et al.
