Abstract Aim Genetic diversity driven by natural selection contributes to population divergence in amphibians, thus facilitating local adaptation climate change. Understanding the mechanisms of genetic is one important issues evolutionary biology. This study set out reveal drivers responsible for intraspecific Fejervarya multistriata and further investigate potential involvement selected genes responding challenges. Location China. Method To identify adaptive traits associated with change, we conducted genome RAD‐seq 300 F. individuals from 15 locations across a bio‐geographical range gradual climatic variation Results The results indicate substantial among populations highlight specific pathways that likely contribute divergence. demographic history can be traced back last interglacial period, during which elevated temperatures may have led significant decline effective size. analysis genome‐climate association identified five candidate ( BMP2K , NRAP ZW10 MYH1 PLB1 ) potentially involved adaptation.

Abstract The species distributions migration poleward and into higher altitudes in a warming climate is especially concerning for economically important insect pest species, as their introduction can potentially occur places previously considered unsuitable year-round survival. We explore the expansion of climatically suitable areas horticultural pest, Mediterranean fruit fly (medfly) Ceratitis capitata (Diptera, Tephritidae), with an emphasis on Europe California. reviewed refined published CLIMEX model C. , taking consideration new records marginal locations, particular focus Europe. To assess fit to aid interpreting meaning European distribution records, we used time series dataset temporal patterns suitability from 1970 2019. At selected bellwether sites Europe, found statistically significant trends increasing suitability, well substantial northward modelled potential range. In California, also trend altitudinal establishment. These results provide further evidence change impacts need innovative responses increased invasion threats.

Effect of temperature on growth, survival, and chronic stress responses of Arctic Grayling juveniles

Transactions of the American Fisheries Society, Journal Year: 2023, Volume and Issue: 153(1), P. 3 - 22

Published: Dec. 26, 2023

Abstract Objective Arctic Grayling Thymallus arcticus are Holarctically distributed, with a single native population in the conterminous United States occurring Big Hole River, Montana, where water temperatures can fluctuate throughout year from 8°C to 18°C. A gradual increase mean temperature has been reported this river over past 20 years due riparian habitat changes and climate change effects. We hypothesized that exposing higher would result lower survival, decreased growth, increased stress responses. Methods Over 144‐day trial, juveniles were subjected ranging 26°C measure effects on gene expression, antioxidant enzyme activity. Result Fish growth increasing up 18°C, beyond which survival was reduced. did not survive at above 22°C. In response 16°C, 3.0‐fold 1.5‐fold increases expression observed for superoxide dismutase ( SOD ) glutathione peroxidase GPx ), respectively, but no seen ratio of heat shock protein 70 90. Activities enzymes also rose indicating heightened oxidative stress. Catalase activity rising temperatures, suggesting preference pathway, as could be providing help lipid peroxidation. An thiobarbituric acid reactive substances recorded, corresponded temperatures. Conclusion Our findings thus underscore vulnerability minor temperature. Further significantly compromise River.
