It is predicted that pollination by birds promotes outcrossing and multiple paternity. Alternatively, pollination by insects or non-flying mammals (NFMs) is expected to increase inbreeding and correlation of paternity, leading to less genetically diverse and less vigorous seedlings. We tested these predictions in Banksia catoglypta (Proteaceae)-an obligately outcrossing heathland shrub pollinated by honeyeater birds, NFMs (honey possums and rodents) and insects (mostly introduced Apis mellifera). Previous research employing selective pollinator exclusion determined that pollination by NFMs was associated with reduced fruit set, compared to flying pollinators. Here, we used microsatellite genotyping of seedling families and a common garden experiment to compare the effectiveness of bird, NFM, and insect pollinators in terms of the genetic quality and vigour of the resulting seedlings. Despite floral traits of B. catoglypta suggesting adaptation to mammalian pollinators, pollination solely by NFMs led to lower multilocus outcrossing rates (tm, indicating biparental inbreeding) and higher correlation of paternity (rp), compared to pollination by flying pollinators (birds and insects combined). Otherwise, there were no significant differences between pollination treatments and open-pollinated controls. Overall, seedling survival was positively correlated with individual heterozygosity, with seedlings resulting from pollination solely by NFMs least likely to survive, and exclusion of NFMs associated with increased seedling survival-although these effects were slight. Our results highlight the importance of quantifying plant mating and seedling fitness for understanding the consequences of pollination by different animals.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 7","pages":"101"},"PeriodicalIF":2.3,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12144075/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144248959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we discuss theories and empirical patterns of deciduous and evergreen habits with a focus on the optimal strategies. Historically, optimal leaf habits and leaf lifespans (LL) have been explained from the viewpoints of carbon economy and nutrient use. In the leaf economics spectrum, deciduous and evergreen species are positioned at the resource-acquisitive and resource-conservative sides of the spectrum, respectively. Seasonal variations in leaf traits of deciduous species could be understood simply as optimization of carbon economy in relation to the progress of the growth season. Evergreen species, however, exhibit more complex patterns, which could be understood as acclimation to seasonal environmental changes or resource allocation to leaf replacement and reproduction. Optimal timing of leaf shedding in evergreen species varies depending on the limiting factor for leaf retention. The return on investment (RI) through the lifetime of a leaf should be greater in evergreen species when there is no environmental suppression. However, RI of evergreen species is often suppressed by seasonal environment or species interaction. Deciduous species can have comparable RIs with evergreen species when they can occupy better environment such as gaps in forests. In conclusion, which leaf habit is advantageous can be understood from trait optimization perspectives. Such knowledge should help forecast how forest ecosystems will respond to changing climate and other anthropogenic environmental impacts.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 7","pages":"99"},"PeriodicalIF":2.3,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12141400/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144226026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evaluating the simultaneous influences of multiple factors on animal space use has been relatively intractable due to sample size limitations. We capitalize on National Ecological Observatory Network (NEON) data to ask what factors determine space use by deer mice (genus Peromyscus). We examined data from 10 years of repeated captures of individually-identified mice at 36 sites across North America. We confirmed previous findings that males have larger home ranges than females and that home range area decreases with increasing animal density. In addition, our large sample size (N = 2,420 individuals) enabled us to examine the interacting influences of these, and other, phenotypic and extrinsic factors using a robust statistical framework. We found that the relationship between body condition and home range area differs between male and female mice, and that habitat type, latitude, and animal density all interact to influence space use. We conclude that data from large ecological networks can be used to examine important behavioral questions that have long eluded investigators.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 7","pages":"98"},"PeriodicalIF":2.3,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12133976/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144216485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hazel dormice Muscardinus avellanarius are known for prolonged winter hibernation but also employ short bouts of torpor of less than 24 hrs, independently of hibernation. In Great Britain, at the edge of the species' range, there is marked spatial and temporal variation in short torpor among individuals and among populations, the causes and consequences of which are not well understood. We quantified variation in torpor use in the dormouse active season and identified individual and population-level correlates of torpor frequency. We analysed the data from the National Dormouse Monitoring Programme, comprising 53,953 observations of adult dormice in nest boxes on 381 sites over 25 years. Short torpor was more frequent at sites towards western Britain, at greater elevation, with more ancient woodland, and greater connectivity of broadleaf woodland. Dormice were more frequently torpid on colder and wetter days, and within colder and wetter seasons. Adult dormice observed in boxes containing young were rarely torpid, while adults alone were more frequently torpid. Lighter individuals were more frequently torpid earlier in the season (April-August) and heavier individuals later (September-October). Sites where short torpor was more frequent had lower counts of dormice and lower counts of breeding events. As a response to short and long-term variation in environmental conditions, short torpor is likely a mediator of environmental drivers of dormouse population dynamics. This is of particular relevance under climate change and at range edges, which already experience adverse environmental conditions.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 6","pages":"97"},"PeriodicalIF":2.3,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12134035/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144209067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the resulting patterns in mean trait values and functional diversity are poorly understood. Bee assemblages in Southwestern drylands are exceptionally diverse, with species varying greatly in their morphological traits. In this study, we addressed two questions: Do climate variables associated with aridity predict community-weighted mean trait values? Has bee assemblage functional diversity declined under increasing aridity? To answer these questions, we utilized 16 years of abundance data for 33 focal bee species within a hyperdiverse bee assemblage at the Sevilleta National Wildlife Refuge (NM, USA), combined with measurements of a suite of five morphological traits hypothesized to mediate climate change responses: body size, wing size, lightness, face hairiness, and thorax hairiness. Our models reveal that community-level responses to climate are trait-specific and vary seasonally: aridity is more predictive in the spring, while temperature and precipitation are more predictive of trait shifts during the monsoon season. With less precipitation, higher temperatures, and increased aridity, bee species that have large bodies, large wings, are lightly colored, and are hairy appear favored. The functional richness of the Sevilleta bee assemblage increased with aridity in the spring and decreased with precipitation in the monsoon season. Functional evenness and functional divergence did not co-vary with any climate variable. We conclude that characteristics of bee assemblages such as community average trait values and functional diversity may change predictably with the increased aridity forecast for this region in the future.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 6","pages":"96"},"PeriodicalIF":2.3,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Phenotypic expression can be altered by direct experiences (i.e., within-generation plasticity) or experiences of previous generations (i.e., transgenerational plasticity). Transgenerational plasticity can help offspring overcome environmental stressors, such as predation, using epigenetic information from their parent(s). Offspring typically receive information from two parents though simultaneous hermaphrodites can produce offspring with varied contributions of epigenetic information by reproducing via outcrossing or self-fertilization (i.e., selfing). While the impact of predation on transgenerational effects has been described, the relative influence of epigenetic information from one or two parental sources is unknown. This study aimed to determine how transgenerational epigenetic effects of predation risk are influenced by selfing and outcrossing. Physid snails were collected and reared over two generations to evaluate anti-predator behavior and shell morphology. The F1 generation was exposed to treatments consisting of all combinations of predation risk and a mate's absence or presence, resulting in six F2 generation treatment lineages. Shell morphometrics and a behavioral assay were completed to quantify the anti-predator response of the F2 generation. We found that the offspring of outcrossers were larger, and their size was influenced by paternal predator treatment. F2 snails were also less likely to exhibit anti-predator behavior after exposure to predation risk. These findings provide insights into our understanding of transgenerational effects in species with various reproductive strategies.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 6","pages":"94"},"PeriodicalIF":2.3,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12125135/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144187459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large seeds are not detected by traditional feces analysis used to describe the diet of Neotropical bats. However, looking for feeding roosts can increase the information related to bats and large-seeded plants interaction. Tent-roosting bats are a specialized group of fruit-eating bats that select and modify leaves to be used as roosts or feeding roosts called tents. We worked along the altitudinal gradient of Braulio Carrillo National Park, we looked for tents, checked large seeds presence under them, and performed a network analysis to determine whether bats have focal species of large-seeded plants. We expected tent-roosting bats to vary their fruit consumption of large-seeded plants along this altitudinal gradient. We also made a literature review to provide a reference for the large-seeded plants consumed by tent-roosting bats. Based on the literature review and the two new interactions recorded in this study, there are 71 species of large-seeded plants dispersed by tent-roosting bats. We found 733 tents, 79 tent-feeding roosts, and 670 seeds corresponding to 12 families under those tents.

This is especially true for my study taxa, wild bees. In this paper, I apply and evaluate an existing but underutilized method to estimate effective density and dispersal distance of bumble bees (Bombus, Apidae). Specifically, using 10 datasets of bumble bees in North America, I use the relationship between genetic isolation-by-distance and Wright's neighborhood size to define a density-dispersal isocline-that is, a curve describing pairs of density and dispersal values consistent with observed rates of isolation-by-distance. These parameters are inversely related; as one increases the other decreases. I then use outside estimates of bumble bee dispersal distances to make more specific estimates of effective colony density. Compared to some prior estimates of census density (100s to 1000s colonies/km2), my estimated effective colony densities were very low (1-41 effective colonies/km2). I also hypothesize, however, that these estimates are affected by the spatial extent of sampling, due to scale-dependent patterns in the distribution of individuals. To test this hypothesis, I subsampled each dataset to simulate varying study extent, and repeated my analysis. Within populations, effective densities tended to decrease when measured across larger spatial extents. Altogether, I demonstrate a useful and under-appreciated tool for studying population biology, especially of small, mobile animals like bees, but also show that researchers must interpret their results carefully within the context of their study design.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 6","pages":"93"},"PeriodicalIF":2.3,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12122646/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144174289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
