Tridacna maxima (T. maxima) are widely distributed in shallow areas near coral reefs and hold significant commercial value as a food source for marine tourism. However, it has been extensively harvested depleted many regions, leading to being listed endangered species by the International Union Conservation of Nature (IUCN). While protected (MPAs) considered effective conservation tools, remains uncertain whether existing MPAs adequately protect these vulnerable giant clams. Here, we employed Species Distribution Models (SDMs) approach, combining occurrence records T. with environmental variables, predict their distribution capture spatiotemporal changes. The findings revealed importance land distance light at bottom determining maxima, suitable habitats predominantly found coastal waters rather than deep sea areas. Furthermore, modeled potential 2050 2100 under different climate change scenarios, highlighting varying impacts on across model predictions. To evaluate current gaps, conducted an analysis overlaying results showed that area is 1,519,764.73 km2, accounting only 16.10% total It became evident insufficiently large or well-connected, suggesting ineffectiveness safeguarding Therefore, management efforts should focus establishing network along coastlines West Pacific-Indonesia, matching dispersal capability These provide valuable insights clams, offering scientific foundation designing MPA networks Indo-Pacific region.

Abstract Morphological diversity within organisms can arise from factors other than genetic alone. Local adaptations and combinations of various are also involved in shaping morphology. We investigated the relationship between morphological ecological niche divergence two related tropical stream‐dwelling newt species Indochina: Paramesotriton deloustali P. guangxiensis . identified sexual dimorphism both a significantly larger body size Our findings highlighted that climatic variables strongly influence Asian warty distribution, indicating potential effects climate change on populations. Furthermore, we significant intra‐ interspecific differentiation across five populations species, suggesting morphology is responsive to environmental factors. A negative was observed only similarity geographic distance among factors, distinct study mirrors adaptation.

Abstract Intraspecific variation, which may arise through the interplay between environmental heterogeneity and adaptive has consequences for resilience of species to climate change. Here, we revealed levels intraspecific genomic variation its causes in a widespread brown alga ( Sargassum horneri ). Our datasets included both benthic floating samples from 20 populations sampled along latitudinal gradient Chinese marginal seas. We prepared two datasets: 1) 4628 filtered single nucleotide polymorphisms (SNPs) all samples, 2) 20,735 SNPs only samples. conducted genotype‐environment association analyses outlier tests identify loci each dataset.

Nowadays, eucheumatoids lead the rankings in globally cultivated seaweed production, including seaweeds Kappaphycus alvarezii and striatus. Eucheumatoids have declined biomass over recent years, climate change is regarded as one of important factors. Thus, it urgent to investigate range dynamics under change. Considering its high practical relevance for conserving biodiversity, niche conservatism hypothesis was tested between two species through ecological modeling (ENM), ordination, hypervolume approach which quantify extent overlap. In this study, we sifted best-performing algorithm - Maxent tuned parameters fitting distribution both species, compared their geographical patterns, predicted All three methodological approaches indicated significant differences environmental space species. Our models that shifts mainly induced by rising sea surface temperature are likely differ with K. striatus suffering much contraction (359,448 km2 2100s RCP8.5).

Understanding the genetic basis of local adaptation in thermal performance is useful for predicting species distribution shifts under anthropogenic climate change. Many are distributed across multiple biogeographic regions, and uniquely adapted populations each region may respond to future ocean warming with distinct changes. In present study, we investigated phylogeographic patterns, sensitivity, differentiation intertidal snail Littorina brevicula along China's coast. Whole-genome sequencing results based on a newly assembled chromosome-level genome revealed two lineages, north-south divergence that linked environment. Within lineage, individuals could be further subdivided into subgroups differ at key genomic loci underpinning differences upper heat tolerance. Heat stress drives adaptive levels organization, from individual level. Taking account diversity associated variation tolerance, physiological model (pSDM) was applied predict distributions different response Both northern southern lineages were predicted experience declines habitat suitability 4°C scenario, genotypic subset snails lineage even driven extinction. These findings illustrate when species' range maintained, it can nonetheless significant decrease as result The integrated approach presented here, which considered both level within biogeographical context, provided new insights how marine global warming.
