All life forms across the globe are experiencing drastic changes in environmental conditions as a result of global climate change. These happening rapidly, incur substantial socioeconomic costs, pose threats to biodiversity and diminish species' potential adapt future environments. Understanding monitoring how organisms respond human-driven change is therefore major priority for conservation rapidly changing environment. Recent developments genomic, transcriptomic epigenomic technologies enabling unprecedented insights into evolutionary processes molecular bases adaptation.

Distinct interspecific and intraspecific vulnerability of coastal species to global change

Global Change Biology, Journal Year: 2021, Volume and Issue: 27(15), P. 3415 - 3431

Published: April 27, 2021

Abstract Characterising and predicting species responses to anthropogenic global change is one of the key challenges in contemporary ecology conservation. The sensitivity marine climate increasingly being described with forecasted distributions, yet these rarely account for population level processes such as genomic variation local adaptation. This study compares inter‐ intraspecific patterns biological composition determine how vulnerability change, its environmental drivers, vary across populations. We compare trajectories three ecologically important southern African invertebrates at two time points future, both level, correlative distribution models, gradient forest models. Reported range shifts are species‐specific include predicted gains losses. Forecasted strongly influenced by changes a suite variables, from sea surface salinity temperature, minimum air temperature. Our results further suggest mismatch between future habitat suitability (where can remain their ecological niche) populations retain composition), highlighting variability species’ change. Overall, this demonstrates importance considering climatic when proactively managing coastal ecosystems Anthropocene.

Seascape Genomics of Elacatinus punctiulatus (Ginsburg, 1938): Understanding the Historical and Contemporary Drivers of Population Structure in the Gulf of California

Molecular Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 31, 2025

The genomic diversity and population structure of marine species represents a complex mosaic shaped by historical contemporary environmental seascape features that maintain or alter it over time. Gulf California (GC) is an interior sea with dynamic history during its formation oceanographic complexity; hence, suitable system to test the effect factors on in species. We investigated redhead goby (Elacatinus puncticulatus; Ginsburg, 1938), cryptobenthic fish, gain insights into drivers shaping GC. A total 4802 SNPs markers were analysed, 3775 loci classified as neutral 27 outlier potentially under selection. Both demonstrated structure, showing two main groups corresponding northern southern locatities. identified additional genetic group emerging central area sampled localities. Genetic differentiation between North South regions demographic simulations was consistent ancient divergence (1.04 Mya) secondary contact (0.15 Mya). association analysis revealed possible adaptive scenario linked ocean temperature. study highlights importance events, factors, circulation E. puncticulatus populations

Climate differently influences the genomic patterns of two sympatric marine fish species

Journal of Animal Ecology, Journal Year: 2021, Volume and Issue: 91(6), P. 1180 - 1195

Published: Oct. 30, 2021

Climate influences population genetic variation in marine species. Capturing these impacts remains challenging for fishes which disperse over large geographical scales spanning steep environmental gradients. It requires the extensive spatial sampling of individuals or populations, representative seascape heterogeneity, combined with a set highly informative molecular markers capable revealing climatic-associated variations. We explored how space, dispersal and environment shape genomic patterns two sympatric fish species Mediterranean Sea, ranks among oceanic basins most affected by climate change human pressure. hypothesized that structure climate-associated signatures selection would be stronger less mobile species, as restricted gene flow tends to facilitate fixation locally adapted alleles. To test our hypothesis, we genotyped contrasting abilities: white seabream Diplodus sargus striped red mullet Mullus surmuletus. collected 823 used genotyping sequencing (GBS) detect 8,206 single nucleotide polymorphisms (SNPs) 2,794 mullet.

Marine reserves are being established worldwide to conserve and manage marine resources, also often assumed the evolutionary potential of populations. However, comparisons genomic patterns inside outside in multiple species scarce. Here, we aim fill this gap by 1) comparing variation protected versus unprotected areas a network eight Mediterranean Sea, 2) disentangling effect seascape, space on 1297 individuals from four genotyped at more than 10 000 SNPs each. We report homogeneous local genetic diversity within three (the white seabream Diplodus sargus , striped red mullet Mullus surmuletus European spiny lobster Palinurus elephas ). Surprisingly, comber Serranus cabrilla shows lower areas, highlighting an apparent conservation paradox that may be due increased predation fishes reserves. Multivariate analyses reveal seascape factors (salinity, temperature chlorophyll) exert significant influence some cases, while protection status has no detectable effect. Nevertheless, (Cabo de Palos, Cerbère‐Banyuls, Cap Creus Illes Columbretes) harbor singular one or two species. This pattern, observed species, suggests contribute preserve locally. Our study illustrates can document key aspects their interaction with factors, It stresses need for multi‐species approach inform planning, opening up new perspectives community level.
