A complete taxonomic revision of the genus Anthothela (Anthothelidae) and closely related taxa is presented herein, based on original type material nominal species additional specimens from multiple deep-water surveys. multi-disciplinary approach was used, combining morphological characteristics such as colonial branching patterns, polyp structure, sclerite form arrangement, together with phylogenetic reconstructions using two mitochondrial gene regions (mtMutS igr1–cox1). The Anthothela,...
Molecular studies have been instrumental for refining species boundaries in the coral genus Pocillopora and revealing hidden diversity within extensively studied global damicornis. Here we formally revise taxonomic status of closely related to P. damicornis complex, taking into account both genetic evidence new data on morphometrics, including fine-scale corallite coenosteum structure. We found that mitochondrial molecular phylogenies are congruent with groups based gross-morphology,...
Abstract Recent molecular research on Antarctic benthic organisms has challenged traditional taxonomic classifications, suggesting that our current perceptions of biodiversity and species distributions must be thoroughly revised. Furthermore, genetic differentiation at the intraspecific level remains poorly understood, particularly in eastern Antarctica. We addressed these issues using DNA sequence data for two sibling amphipod could collected a circum‐Antarctic scale: Eusirus perdentatus...
1 For a wide range of organisms, heritable variation in life-history characteristics has been shown to be strongly subject selection, reflecting the impact that characters such as genotypic diversity, duration larval development and adaptations for dispersal can have on fitness offspring make-up populations. Indeed, characteristics, especially reproduction type, often used predict patterns resultant population structures marine invertebrates. 2 Scleractinian corals are excellent models with...
The coral genus Pocillopora is one of the few to include some species that broadcast spawn gametes and brood larvae, although reports reproductive mode timing vary within among across their range. Notably, ubiquitous damicornis has been described as both a brooder spawner, evidence spawning rare. Here, we report observations broadcast-spawning in four on Great Barrier Reef (GBR), including P. damicornis. All spawned predictably during early morning, two days following full moon, was observed...
Deep sea scleractinian corals will be particularly vulnerable to the effects of climate change, facing loss up 70% their habitat as Aragonite Saturation Horizon (below which are unable form calcium carbonate skeletons) rises. Persistence deep therefore rely on ability larvae disperse to, and colonise, suitable shallow-water habitat. We used DNA sequence data internal transcribed spacer (ITS), mitochondrial ribosomal subunit (16S) control region (MtC) determine levels gene flow both within...
Abstract Ecological processes in the deep sea are poorly understood due to logistical constraints of sampling thousands metres below ocean’s surface and remote from most land masses. Under such circumstances, genetic data provides unparalleled insight into biological ecological relationships. We use microsatellite DNA compare population structure, reproductive mode dispersal capacity two corals seamounts Southern Ocean. The solitary coral Desmophyllum dianthus has widespread consistent with...
High-latitude coral reefs (HLRs) are potentially vulnerable marine ecosystems facing well-documented threats to tropical and exposure suboptimal temperatures insolation. In addition, because of their geographic isolation, HLRs may have poor or erratic larval connections a reduced genetic diversity capacity respond environmental change. On Australia's east coast, system protected areas (MPAs) has been established with the aim conserving in part by providing sources colonizing larvae. To...
Abstract Understanding the boundaries of breeding populations is great importance for conservation efforts and estimates extinction risk threatened species. However, determining these can be difficult when population structure subtle. Emperor penguins are highly reliant on sea ice, some may in jeopardy as climate change alters sea‐ice extent quality. An understanding emperor penguin therefore urgently needed. Two previous studies have differed their conclusions, particularly whether Ross...
Abstract The predominance of self‐recruitment in many reef‐building corals has fundamental and complex consequences for their genetic diversity, population persistence responses to climate change. Knowledge structure over local scales needs be placed within a broad spatial context, also integrated with monitoring through time disentangle these consequences. Here, we examined patterns diversity multiple spatio‐temporal across tropical Australia the ubiquitous brooding coral, Seriatopora...
In this study, we report the cloning and expression of lipase gene from Pseudomonas fluorescens B52, a psychrotrophic spoilage bacterium isolated refrigerated raw milk. Sequence analysis revealed one major open reading frame 1,428 nucleotides that was predicted to encode protein with molecular weight 50,241. The enzyme found contain an amino acid sequence highly homologous putative substrate-binding domain present within all lipases examined date.
Abstract Genetic data were used as an indirect means of assessing connectivity among deep‐sea coral populations on seamounts and slopes in the Australian New Zealand region. We sequenced three DNA regions (16S, ITS Control Region) nine species from sites spanning thousands kilometers. Based haplotype distributions AMOVA, we found evidence genetic subdivision across ocean expanses for species: scleractinian Desmophyllum dianthus , antipatharians Antipathes robillardi Stichopathes variabilis ....
Abstract This article documents the addition of 205 microsatellite marker loci to Molecular Ecology Resources Database. Loci were developed for following species: Bagassa guianensis, Bulweria bulwerii, Camelus bactrianus, Chaenogobius annularis, Creontiades dilutus, Diachasmimorpha tryoni, Dioscorea alata, Euhrychiopsis lecontei, Gmelina arborea, Haliotis discus hannai, Hirtella physophora, Melanaphis sacchari, Munida isos, Thaumastocoris peregrinus and Tuberolachnus salignus . These...
The mechanisms that determine patterns of species dispersal are important factors in the production and maintenance biodiversity. Understanding these helps to forecast responses environmental change. Here, we used a comparative framework genomewide data obtained through RAD-Seq compare connectivity among breeding colonies for five penguin with shared ancestry, overlapping distributions differing ecological niches, allowing an examination intrinsic extrinsic barriers governing patterns. Our...
Overexploitation of marine species invariably results in population decline but can also have indirect effects on ecological processes such as larval dispersal and recruitment that ultimately affect genetic diversity resilience. We compared microsatellite DNA variation among depleted healthy populations the black-lip abalone Haliotis rubra from Tasmania, Australia, to determine if over-fishing had affected diversity. used data assess whether scale frequency was linked greater some regions...
