In these populations, the presence of both resident and migrant individuals (termed partial migration) is common, but how migrants and residents differ in their selection of farmland is not well-understood. Higher access to farmland may provide benefits to residents compensating for not following the 'green wave' of emerging vegetation such as migrants. According to sexual segregation theory, males and females differ in body-size-related nutritional needs and risk sensitivity associated with farmland. Yet, how the sexes differ in the selection of farmland through an annual cycle remains unclear. We quantified seasonal variation in the selection of farmland by partially migratory red deer (Cervus elaphus) at broad, landscape scale and at fine, within-home range scale using 16 years of data (2005-2020) from 329 females and 115 males in Norway. We tested predictions related to the partial migration and sexual segregation theories using resource selection functions. We predicted higher selection for farmland by residents than by migrants, and higher selection by females than by males due to higher nutritional needs, but that higher perceived predation risk would impact their diurnal selection patterns. The time spent on farmland was higher in winter (14%-18%) than in summer (8%-14%). Residents selected farmland more than migrants mainly at broad, landscape scale, while differences were smaller and less consistent at a fine, within-home range scale. Females showed higher broad-scale selection for farmland in winter, whereas males showed higher selection in summer. At a fine, within-home range scale, females selected farmland more in summer during darkness, whereas sex differences were small otherwise. The fine-scale selection of farmland was markedly higher during low-light conditions than in daylight. A high population density index was correlated with high broad-scale selection of farmland, i.e. high farmland availability in the home ranges, whereas the effect of the density index was weak at a fine, within-home range scale. Our study emphasises how hypotheses deriving from the theories of partial migration and sexual segregation can improve our understanding of ungulates' selection of farmland. The higher selection by residents during summer highlights the importance of retaining landscape connectivity, allowing for migration and reducing pressure on local resources.</p>","PeriodicalId":14934,"journal":{"name":"Journal of Animal Ecology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143515823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trophic interactions such as herbivory and predation are crucial regulators of ecological communities, yet few examples exist for these processes within host-associated microbiomes. In a recent study, Matthews et al.

The authors quantified the bacterial and fungal diet of commensal feather mites and compared this with the composition of microbial communities living directly on the feather. They found that, despite a large variety of microbes to choose from, mites strongly preferred to eat a small number of bacterial and fungal genera. Some of these selectively enriched taxa are known keratin-degraders, suggesting that mites may protect feathers by selectively consuming harmful microbes.

(2024). Seasonally variable thermal performance curves prevent adverse effects of heatwaves. Journal of Animal Ecology. https://doi.org/10.1111/1365-2656.14221. Marine heatwaves (MHWs) emerge as a devastating stressor that can have direct and transgenerational effects on marine organisms. However, we know very little about how seasonal variations in thermal performance curves (TPCs) may help marine zooplankton cope with these direct and transgenerational effects of MHWs. In a recent study, Sasaki et al. (2024) combined field observations and simulated laboratory heatwave experiments, uncovering seasonal variations in TPCs for key fitness-related traits, including egg and offspring production, hatching success and survivorship in two ecologically important copepod species Acartia tonsa and A. hudsonica. They discovered that the TPC of A. tonsa was highly seasonally variable, allowing them to maintain their thermal optimum of at least 5°C above the field temperature. The transgenerational effects of parental exposure to MHWs on the offspring were minor. In contrast, the TPC of A. hudsonica was relatively unchanged across seasons, suggesting that this species may be highly vulnerable to MHWs, especially during summer. These findings agree with distinct seasonal abundances of the two species in nature: A. hudsonica is primarily abundant during winter and spring while A. tonsa dominates the summer and fall. These findings enhance our understanding of how seasonal variations in TPCs can determine the vulnerability of marine species to heatwaves through direct and transgenerational effects, which are important for ecological risk assessments of marine ecosystems under a rapidly changing climate.</p>","PeriodicalId":14934,"journal":{"name":"Journal of Animal Ecology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143476639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stress levels tend to fluctuate, and long-term increases in average stress levels are often accompanied by greater amplitudes of such fluctuations. Micro-evolutionary adaptation may allow populations to cope with gradually increasing stress levels but may not prevent their extirpation during acute stress events unless adaptation to low stress levels also increases their tolerance to acute stress. We tested this idea, here called 'micro-evolutionary priming', by exposing populations of the monogonont rotifer species Brachionus calyciflorus to four levels of copper stress (control, low, intermediate and high) during a multigenerational selection experiment. Subsequently, in a common garden experiment, we exposed randomly selected subsets of genotypes (clones) of each of these populations to low, intermediate and high copper levels and assessed their population growth performance across multiple generations. Compared to populations with an exposure history to copper, genotypes of control populations suffered strong growth reductions when exposed to intermediate and high levels of copper, mainly as a result of high mortality rates. Remarkably, when exposed to low copper levels, fitness differences between genotypes of control populations and populations adapted to these low levels were very small, whereas the latter strongly outperformed the former at intermediate and high copper levels. These results highlight the potentially strong but hitherto largely ignored impact of micro-evolutionary priming on the performance of populations in a changing environment. We discuss the potential consequences of micro-evolutionary priming for the persistence of populations and the spatial eco-evolutionary dynamics of metapopulations.</p>","PeriodicalId":14934,"journal":{"name":"Journal of Animal Ecology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143458007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
