The southeast Australian coast potentially includes a complex biogeographic barrier, largely lacking exposed rocky shore that may limit the dispersal of intertidal taxa and contribute to maintenance two regions. Surprisingly, within 300-km barrier region, several species considered specialists occurred sheltered sites. We analysed COI sequence variation for 10 invertebrate species, with range life histories, test hypotheses larval type habitat specificity are strong predictors gene flow...
Abstract The climate‐driven dynamics of species ranges is a critical research question in evolutionary ecology. We ask whether present intraspecific diversity determined by the imprint past climate. This an ongoing debate requiring interdisciplinary examination population genetic pools and persistence patterns across global ranges. Previously, contrasting inferences predictions have resulted from distinct genomic coverage and/or geographical information. aim to describe explain causes...
Abstract New Zealand's 14 deep‐water fiords possess persistent salinity stratification and mean estuarine circulation that may serve to isolate populations of marine organisms have a dispersal larval phase. In order investigate this idea, we analysed the population structure sea star Coscinasterias muricata using mitochondrial DNA marker. Genetic differentiation among C. was 366 base pairs mtDNA D‐loop. We compared from with several others sampled around Zealand. At macro‐geographical scale...
Patterns in morphology, pigment concentration, and light saturation kinetics of Ecklonia radiata reveal great morphological physiological variability among individuals from sites spanning strong gradients topographic shading wave exposure the 14 fjords southwestern New Zealand. Morphology E. varies relatively narrow (85 ± 4.7 mm) (mean standard error), thick (3.2 0.30 blades well‐illuminated, wave‐exposed outer coast to wide, undulate (460 36.8 mm,) thin (0.46 0.059 quiescent,...
The implications of mating system for genetic diversity were assessed in the sister species Fucus spiralis and vesiculosus using a combination ten microsatellite markers. Five new markers specific F. developed order to increase marker resolution complement results (i.e. extended larger geographic scale) acquired five loci previously from mixed fucoid seaweed DNA library that excluded spiralis. Low diversities observed at population level spiralis-specific described here consistent with...
In the leuphotrochozoan parasitic platyhelminth Schistosoma mansoni, male individuals are homogametic (ZZ) whereas females heterogametic (ZW). To elucidate mechanisms that led to emergence of sex chromosomes, we compared genomic sequence and chromatin structure female individuals. As for many eukaryotes, lower estimate repeat content is 40%, with an unknown proportion domesticated repeats. We used massive sequencing de novo assemble all repeats, identify unambiguously Z-specific, W-specific...
Abstract Background Hybridization or divergence between sympatric sister species provides a natural laboratory to study speciation processes. The shared polymorphism in may either be ancestral derive from hybridization, and the accuracy of analytic methods used thus far convincing evidence for occurrence present day hybridization is largely debated. Results Here we propose application network analysis test two brown algae Fucus spiralis F. vesiculosus . Individual-centered networks were...
The digenetic trematode Schistosoma mansoni is a human parasite that uses the mollusc Biomphalaria glabrata as intermediate host. Specific S. strains can infect efficiently only certain B. (compatible strain) while others are incompatible. Strain-specific differences in transcription of conserved family polymorphic mucins (SmPoMucs) principle determinants for this compatibility. In present study, we investigated bases control SmPoMuc expression evolved to evade diversified antigen...
A decade ahead of their time, von Schantz et al. united sexual selection and free radical biology by identifying causal links between deep-rooted physiological processes that dictate resistance to toxic waste from oxidative metabolism (reactive oxygen species, ROS), phenotypic traits, such as ornaments. Ten years later, these ideas have still only been tested with indirect estimates levels (oxidative stress) subsequent the action innate dietary antioxidants. Here, we measure net superoxide...
Sequence analysis of a fragment the cytochrome b gene in Decapterus russelli sampled from Indo‐Malay archipelago revealed two distinct mitochondrial clades (mean nucleotide divergence=2·2%) whose geographic distribution was heterogeneous (Nei's G ST =0·416). This pointed to complex pattern genetic differentiation and demonstrated limited exchange between populations this highly mobile species.
The southern range limit of the planktotrophic, intertidal whelk, Morula marginalba, occurs immediately to north south-east Australian biogeographical barrier and we predict that its may be limited by dispersal biotic interactions. includes several hundred kilometers without suitable habitat is convergence zone major ocean currents. Within region, along-shore larval transport expected erratic, with water moving offshore form long-lived eddies. Through comparison central edge populations,...
Hox genes are recognized for their explanatory power of bilateral development. However, relatively little is known about natural variation in, and the evolutionary dynamics of, within wild populations. Utilizing a population sand lizards (Lacerta agilis), we screened HoxA13 genetic an association with incidence offspring malformations. We found significant effects parental similarity sex, interaction, on risk hatching malformed as offspring. also in HoxA13, identified effect three-way...
