Abstract Loss of biodiversity is among the greatest problems facing world today. Conservation and Genomics Populations gives a comprehensive overview essential background, concepts, tools needed to understand how genetic information can be used conserve species threatened with extinction, manage ecological or commercial importance. New molecular techniques, statistical methods, computer programs, principles, methods are becoming increasingly useful in conservation biological diversity.

Natural hybridization reduces vulnerability to climate change

Nature Climate Change, Год журнала: 2023, Номер unknown

Опубликована: Янв. 30, 2023

Abstract Under climate change, species unable to track their niche via range shifts are largely reliant on genetic variation adapt and persist. Genomic vulnerability predictions used identify populations that lack the necessary variation, particularly at climate-relevant genes. However, hybridization as a source of novel adaptive is typically ignored in genomic studies. We estimated environmental models for closely related rainbowfish ( Melanotaenia spp.) across an elevational gradient Australian Wet Tropics. Hybrid between widespread generalist several narrow endemic exhibited reduced projected climates compared pure endemics. Overlaps introgressed regions were consistent with signal introgression. Our findings highlight often-underappreciated conservation value hybrid indicate introgression may contribute evolutionary rescue ranges.

Genomics for monitoring and understanding species responses to global climate change

Nature Reviews Genetics, Год журнала: 2023, Номер 25(3), С. 165 - 183

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. This Review summarizes methods that apply integrate omics tools experimentally investigate, monitor predict species communities wild cope with change, which by genetically adapting new conditions, through range shifts or phenotypic plasticity. We identify advantages limitations each method discuss research avenues would improve our understanding responses highlighting need holistic, multi-omics approaches ecosystem during Species can shifting their these responses.

Genome of the estuarine oyster provides insights into climate impact and adaptive plasticity

Communications Biology, Год журнала: 2021, Номер 4(1)

Опубликована: Ноя. 12, 2021

Abstract Understanding the roles of genetic divergence and phenotypic plasticity in adaptation is central to evolutionary biology important for assessing adaptive potential species under climate change. Analysis a chromosome-level assembly resequencing individuals across wide latitude distribution estuarine oyster ( Crassostrea ariakensis ) revealed unexpectedly low genomic diversity population structures shaped by historical glaciation, geological events oceanographic forces. Strong selection signals were detected genes responding temperature salinity stress, especially expanded solute carrier families, highlighting importance gene expansion environmental adaptation. Genes exhibiting high showed strong upstream regulatory regions that modulate transcription, indicating favoring plasticity. Our findings suggest variation structure marine bivalves are heavily influenced history physical forces, may enhance critical rapidly changing environments.

Critical thermal maxima in aquatic ectotherms

Critical Thermal Maxima (CTMax) is one of the main used techniques to infer thermal tolerance a certain organism. Aquatic animals, which are mainly ectotherms, believed present growing CTMax from poles towards equator while their tolerance, in relation environmental temperature would opposite trend. In this work such pattern analysed global scale by performing metanalysis with previous data. Also, differences between organisms living fresh and saltwater ecosystems different taxa were assessed. Finally, effect other stressors over compiled discussed. It was possible prove that, as it has been proposed, values have an inverse being tropical closer limit than climates. temperate present, general, highest tolerance.

Climate is changing, are European bats too? A multispecies analysis of trends in body size

Abstract Animal size, a trait sensitive to spatial and temporal variables, is key element in ecological evolutionary dynamics. In the context of climate change, there evidence that some bat species are increasing their body size via phenotypic responses higher temperatures at maternity roosts. To test generality this response, we conducted >20‐year study examining changes 15 Italy, analysing data from 4393 individual bats captured since 1995. addition effect, considered potential influence sexual dimorphism and, where relevant, included latitude altitude as drivers change.

Plasticity to ocean warming is influenced by transgenerational, reproductive, and developmental exposure in a coral reef fish

Global warming is expected to drive some ectothermic species beyond their thermal tolerance in upcoming decades. Phenotypic plasticity, via developmental or transgenerational acclimation, a critical mechanism for compensation the face of environmental change. Yet, it remains be determined if activation beneficial phenotypes requires direct exposure throughout development, can obtained just through experience previous generations. In this study, we exposed three generations tropical damselfish combinations current-day (Control) and projected future (+1.5°C) water temperatures.
