Abstract Accelerating climate change and extreme temperatures urge us to better understand the potential of populations tolerate adapt thermal challenges. Interspecific hybridization can facilitate adaptation novel or environments. However, predicting long-term fitness effects remains a major challenge in evolutionary conservation biology. Experimental evolution with microbes provides powerful tool for tracking adaption, across generations real time. We investigated dynamics four species budding yeast ( Saccharomyces ) their interspecific F2 hybrids, 140 under cold (5°C) warm (31°C) conditions.We found significant variation strongly determined by natural temperature tolerance. The largest improvements occurred some nearly quadrupling environment, exceeding both parents adaptive potential. Reciprocal transplanting evolved from endpoint into opposite revealed that hybrids had greater resilience when challenged sudden shifts. Our results highlight alters outcomes environments may render more resilient environmental change, presenting opportunities challenges sustainable agriculture.

Abstract Climate‐induced expansion of invasive hybridization (breeding between and native species) poses a significant threat to the persistence many species worldwide. In northern U.S. Rocky Mountains, cutthroat trout non‐native rainbow has increased in recent decades due, part, climate‐driven increases water temperature. It been postulated that may enhance physiological tolerance climate‐induced thermal stress because laboratory studies indicate have higher than trout. Here, we assessed whether improves cardiac performance response acute temperature wild populations. We collected from four streams with wide range admixture among individuals different streamflow regimes upper Flathead River drainage, USA. measured individual (maximum heart rate, “MaxHR”, at arrhythmia, “ArrTemp”) during trials increasing temperatures (10–28°C). Across study populations, observed substantial variation when exposed stress. Notably, found differences suggesting importance genotype‐by‐environment interactions shaping However, had no effect on (MaxHR ArrTemp) within any three Our results warmer‐adapted does not under warming conditions. Maintaining numerous populations across thermally hydrologically diverse stream environments will be crucial for adapt persist climate.

Abstract This article summarizes the Special Issue of Evolutionary Applications focused on “Advances in Salmonid Genetics.” Contributions to this were primarily presented at Coastwide Genetics Meeting, held Boise, ID June 2023, with a focus Pacific salmonids west coast region North America. from other regions globe are also included and further convey importance various salmonid species across world. is comprised 22 articles that together illustrate major advances genetic genomic tools address fundamental applied questions for natural populations salmonids, ranging mixed‐stock analyses, conservation diversity, adaptation local environments. These studies provide valuable insight molecular ecologists since systems offer window into evolutionary applications parallel efforts relevant applicable beyond species. Here, we an introduction synopsis Issue, along future directions field. We present honor Fred Utter, founder leader field genetics, who passed away 2023.
