The degree of genetic differentiation among populations experiencing high levels gene flow is expected to be low for neutral genomic sites, but substantial divergence can occur in sites subject directional selection. Studies highly mobile marine fish provide an opportunity investigate this kind heterogeneous differentiation, most studies effect have focused on a relatively number markers and/or few populations. Hence, the patterns and extent high-gene remain poorly understood.We here...
Linking genetic diversity to extinction is a common goal in genomic studies. Recently, debate has arisen regarding the importance of variation conservation as some studies have failed find associations between genome-wide and risk. However, only rarely are fitness measured together wild, typically demographic history environment ignored. It therefore difficult infer whether lack an association real or obscured by confounding factors. To address these shortcomings, we analyzed data from 7,501...
A new species of Microhyla frog from the Nilphamari district Bangladesh is described and compared with its morphologically similar geographically proximate congeners. Molecular phylogeny derived mitochondrial DNA sequences revealed that although species--designated here as nilphamariensis sp. nov.--forms a clade M. ornate, it highly divergent ornata all congeners, 5.7-13.2% sequence divergence at 16S rRNA gene. The can be identified phenotypically on basis set diagnostic (both qualitative...
The study of parasitic species can shed light on aspects their hosts ecology. Such interactions are however often unknown or understudied due to the difficulty detect and/or quantify many infections. Whole-genome sequencing and re-sequencing data have been generated at an increasing rate reduced costs over last two decades. Projects based whole organisms, like insect specimens, provide genomic material for target taxon, but may also include reads from associated microbes other parasites....
A fragmented habitat becomes increasingly for species at higher trophic levels, such as parasitoids. To persist, these are expected to possess life-history traits, high dispersal, that facilitate their ability use resources become scarce in landscapes. If a specialized parasitoid disperses widely take advantage of sparse host, then the population should have lower genetic structure than host. We investigated temporal and spatial hyperparasitoid (fourth level) landscape over 50 × 70 km, using...
Adapting to changes in the environment is foundation of species survival, and usually thought be a gradual process. However, transposable elements (TEs), epigenetic modifications, and/or genetic material acquired from other organisms by means horizontal gene transfer (HGTs), can also lead novel adaptive traits. Social insects form dense societies, which attract maintain extra- intracellular accessory inhabitants, may facilitate between species. The wood ant Formica exsecta (Formicidae;...
Abstract Amphibians are rapidly declining worldwide, but recent studies have shown that their diversity may be heavily underestimated, and many new species been recently reported from biodiversity hotspots. For successful conservation management strategies to implemented within such hotspots, a better understanding of the evolutionary relationships is required. We used three mitochondrial ( 16S , 12S CO1 ) two nuclear rag1 rhodopsin gene fragments investigate genetic endemic I ndirana genus...
Comparative phylogeography has become a powerful approach in exploring hidden or cryptic diversity within widespread species and understanding how historical biogeographical factors shape the modern patterns of their distribution. Most comparative phylogeographic studies so far focus on terrestrial vertebrate taxa, while aquatic invertebrates (and especially freshwater invertebrates) remain unstudied. In this article, we explore compare molecular structure four copepod crustaceans European...
A new species of the genus Euphlyctis is described from Barisal district Bangladesh and compared with its morphologically similar geographically proximate congeners. The highly divergent in comparison to other congeneric on basis sequence divergence mitochondrial DNA gene sequences (ranging 5.5% 17.8% divergence). kalasgramensis sp. nov. can be readily diagnosed by having following combination characters: snout-vent length (SVL) 30.44 – 37.88 mm, absence mid-dorsal line, nostril–snout 3%...
We describe a new species of frog the genus Zakerana discovered from urban core Dhaka, Bangladesh, one most densely populated cities in world. Although is morphologically similar to geographically proximate congeners Bangladeshi cricket group, we show that it can be distinguished all on basis morphological characters, advertisement calls and variation two mitochondrial DNA genes (12S rRNA 16S rRNA). Apart several diagnostic differences body proportions, differs other having flattened snout...
Abstract Background The Glanville fritillary (Melitaea cinxia) butterfly is a model system for metapopulation dynamics research in fragmented landscapes. Here, we provide chromosome-level assembly of the butterfly's genome produced from Pacific Biosciences sequencing pool males, combined with linkage map population crosses. Results final size 484 Mb an increase 94 on previously published genome. Estimation completeness BUSCO indicates that contains 92–94% genes complete and single copies. We...
Tropical mountain ranges are known to support high biodiversity.In addition their role as refuge habitat, complex topography within these ecosystems promotes the development of diverse species traits and evolutionary divergence.However, environments also face severe anthropological threats, most notably from habitat loss degradation, invasive species, climate change.A primary example is Taita Hills in Kenya, which forms northernmost portion biodiversity rich Eastern Arc Mountains.Despite...
Microsatellite loci are widely used in population and conservation genetic studies of amphibians, but the availability such markers for tropical subtropical taxa is currently very limited. In order to develop resources genus Indirana, we tested amplification success polymorphism 62 previously developed microsatellite loci, eight Indirana species - including new candidate species. Developing genomic this amphibian taxon particularly important as it endemic Western Ghats biodiversity hotspot,...
Frogs of the genus Indirana belong to endemic family Ranixalidae and are found exclusively in Western Ghats biodiversity hotspot. Since taxonomy, biology distribution these frogs still poorly understood, we conducted a comprehensive literature review what is known on morphology, life history characteristics breeding species. Furthermore, collected information geographical locations mentioned literature, combined this with from our own field surveys order generate detailed maps for each Apart...
Garlic bulb is an important seasoning ingredient and used in countless world’s cuisines. Clonal lineages within this species exhibit high degree of phenotypic diversity size colour. Present review describes morphology, taxonomy, chemistry, cultivation, medicinal properties, post harvest processing biotechnological approaches for improvement. Special emphasis laid on the genetic variations garlics with special Indian accessions. The available results are divergent; some studies indicate that...
In the present study, we screened 32 Indian garlic (Alliumsativum) germplasm to identify bolting genotype using threemitochondrial DNA based molecular markers, P1, P2, andP3. two different combinations P1+P2 and P1+P3. 1.4 kbamplicon was obtained with bolt marker in all 32screened accessions which showed inherent ability ofbolt further needs impose intensewinter. Further, consistency of result confirmed withP1+P3 mitochondrial producesthe amplicon 3.7kb size, on basis nonsynchronizationin...
Climate change can increase spatial synchrony of population dynamics, leading to large-scale fluctuation that destabilizes communities. High trophic level species such as parasitoids are disproportionally affected because they depend on unstable resources. Most parasitoid wasps have complementary sex determination, producing sterile males when inbred, which theoretically lead extinction via the diploid male vortex (DMV). We examined this process empirically using a hyperparasitoid inhabiting...
