Interaction turnover consists of interaction rewiring (i.e., changes in interactions independent of species turnover) and species turnover (i.e., the gain or loss of species present in the network). To capture network dynamics, it is crucial to address the effect of sampling effort because insufficient data can distort apparent network patterns. We used eight years of plant-pollinator interaction data from a subalpine meadow to examine patterns of temporal (week-to-week) interaction turnover and the role of sampling effort. With increasing sampling effort, values of interaction turnover and species turnover decreased, and rewiring increased. Saturation curves suggest an approach towards true values with higher sampling effort. Across the eight years, substantial variation in weekly and seasonal interaction turnover was observed, with identifiable seasonal trends across all aggregated years. These results demonstrated that the interpretation of interaction turnover and its components is sensitive to sampling effort, stressing the importance of considering its role in network studies.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 8","pages":"131"},"PeriodicalIF":2.3,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12254060/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144608955","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, as developmental processes are inherently difficult to measure directly at the population level, the drivers and potential consequences of change in their timings remain unknown in most species. Here we explore the use of long-term monitoring data for assessments of change in the number of generations per year and its impact on abundance, demonstrating new applications for a rapidly growing data source. Data derived from a light trap in west-central Scotland operated over 56 years (1968 to 2023) showed that the small phoenix moth, Ecliptopera silaceata, switched from a univoltine to bivoltine generation pattern. This voltinism change was predicted by an increased minimum temperature in a critical time window towards the later part of the first generation's flight period. The population shows positive density dependence and the change in voltinism has no significant negative effect on population size, indicating no evidence of a developmental trap that has been postulated for other species. These results identify some of the proximate mechanisms of developmental responses to climate change in general and in voltinism in particular, specifically highlighting the importance of sustained temperature above minimum thresholds for development. These results could also help to make predictions about future changes in population sizes under climate change and increasing voltinism, in addition to how these changes may differ between species.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 8","pages":"129"},"PeriodicalIF":2.3,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12241285/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144601136","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}

Here, we investigate whether predatory intertidal snails (the dogwhelk Nucella canaliculata) vary in their drilling capacity in association with prey defenses (mussel shell thickness) over ~ 1000 km of coastline in the northeast Pacific. We analyzed mussels (Mytilus californianus) collected over two decades and found that shells from central Oregon were historically ~ 20% thicker than those from California. We tested the drilling capacity of dogwhelks raised under common-garden laboratory conditions and found that dogwhelks from California could drill mussels 3.4 times thicker than those from Oregon. Thus, dogwhelks with stronger drilling ability are associated with thinner mussel shells. Although these findings appear counterintuitive at first, they are consistent with strong prey-driven selection on the predator in California, and a region of weak selection in Oregon where mussels may be too thick to favor drilling. Our results also suggest that this selective landscape may be changing; consistent with recent studies of ocean acidification, mussels collected in 2019 were thinner than in prior decades, particularly in Oregon. Overall, our study highlights the importance of studying species interactions within an explicit geographic context of shifting selection pressures.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 8","pages":"126"},"PeriodicalIF":2.3,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12238184/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144591883","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}

Stegastes damselfishes are small, mostly reef-associated fishes that are common in shallow tropical and sub-tropical marine environments. Both sexes defend a territory consisting of their food supply and shelter sites, with male territories also including a nest where females lay eggs which are then guarded by the male. Females therefore need to leave their territory to spawn in male nests, putting them at risk of attack during travel and leaving their territory exposed to intruders while away. Female egg-laying tactics can vary among and within species-some complete spawning during a single, extended bout, while others do so in multiple bouts, separated by visits to their territory. Spawning behavior and behaviors associated with territoriality of 101 individuals from 6 species were observed between June 2022 and May 2023 to identify and quantify the factors that influence variation in spawning tactics both within and among Stegastes species. Specifically, we tested two predictions of the hypothesis that dividing spawning with a single male into bouts allows individuals to balance the tradeoff between travel costs and intruder pressure for females of permanently territorial damselfishes: (1) intruder pressure will be positively related to the number of spawning trips among species and/or among females within species; and (2) travel distance will be negatively related to the number of spawning trips. Results of this study showed that Stegastes females increase their spawning bouts with an increase in intruder pressure and decrease their spawning bouts with an increase in travel distance.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 8","pages":"127"},"PeriodicalIF":2.3,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12238210/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144591885","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}

Genetic admixture, whether intra- or interspecific, may offer a solution by enhancing the genetic diversity and adaptability of the population. Here, we explore the role of genetic admixture in the rapid establishment and adaptation of the Italian wall lizard (Podarcis siculus) introduced on Pod Mrčaru, a small islet in the Adriatic Sea. Introduced in 1971 in a small group of ten individuals from a nearby island, this population rapidly adapted to its new environment, outcompeting the native Dalmatian wall lizard (Podarcis melisellensis) and exhibiting striking ecological and phenotypic shifts. Using whole-genome sequencing data from P. siculus populations on Pod Mrčaru and neighbouring islands and from P. melisellensis, we investigated population structure, admixture, and gene flow to test whether inter- or intraspecific genetic exchange contributed to the successful establishment and divergence of the introduced population. Despite the sympatric presence of P. melisellensis during the introduction of P. siculus on Pod Mrčaru, and thus the opportunity for genetic exchange, we found no evidence of hybridisation between the two species. Even amongst neighboring island populations of P. siculus, we observed only limited gene flow, suggesting relatively independent evolution of the populations since their establishment on the islands. These findings highlight the potentially significant roles of distinct selective pressures and/or ecological and phenotypic plasticity, rather than genetic exchange, in driving the population's rapid adaptation to a novel environment.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 7","pages":"125"},"PeriodicalIF":2.3,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144584384","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}

Plant-pollinators networks experience various influences from biotic and abiotic factors across elevation gradients and flowering seasons, impacting species distribution, interactions, and community structures. In our study, we examined plant-pollinator network structures at 14 sites across elevations from 1000 to 1800 m above sea level in a Mediterranean mountainous area. The study aimed to determine if plant-pollinator network structures remain consistent across different spatial contexts (elevations and habitats) and to assess the impact of abiotic drivers on network structure. We documented a total of 3343 interactions involving 343 pollinator species and 44 plant species, with bees and flies as prominent participants. Results showed low nestedness, which increased only with rainfall, and was generally higher in forests than in outcrop areas. High specialization was noted, with an increase in specialization correlated with rainfall. Network modularity was more pronounced in outcrops compared to forests, with soil temperature and rainfall boosting modularity. Interaction diversity was greater in outcrops and showed a positive relationship with rainfall. High robustness correlated inversely with specialization. Our findings highlight that flower and pollinator diversity, combined with climatic factors, predict network modularity, specialization, and robustness. This research illustrates how network structures differ across habitat types and elevation, revealing potential vulnerabilities of plant-pollinator interactions to environmental changes throughout the flowering season. We also highlight the potential impact of climate change on pollination networks on mountain areas (as hotspots of biodiversity).","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 7","pages":"122"},"PeriodicalIF":2.3,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144554056","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}

Many plants emit high-frequency clicks under water stress or injury, and the growing root tips of corn seedlings produce audio-frequency clicks. We investigated the possibility that rapid plant movements produce acoustic cues in the form of plant-borne vibration, focusing on the leaf-folding movements of the sensitive plant, Mimosa pudica. We induced leaf-folding while recording vibrations from the leaf base using a laser vibrometer. Having recorded characteristic and relatively high-amplitude vibrations, we then assessed the source of the vibrations: the physiologic motor that drives movement, or the contact between moving parts of the leaf. Vibrations were produced when folding pinnules contacted neighboring pinnules and the rachis of the stem. The frequency range and amplitude of the vibrations are comparable to other vibrational cues that both plants and insects perceive and respond to. In nature, leaf folding is induced by contact with potential herbivores. Potential receivers of leaf-folding vibrations include the attacking herbivore, for which the leaf movement and vibration may constitute a multimodal startle display; nearby predatory insects, for which the vibration provides a cue of prey location; and leaves on the same or neighboring plants.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 7","pages":"124"},"PeriodicalIF":2.3,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144560690","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}

Central place foragers are particularly affected. Their efficiency at replenishing their body reserves at sea while feeding their offspring on land relies on accurately targeting predictable foraging locations. Therefore, increased time and effort spent searching for resources is likely to compromise reproduction. Here, we used an experimental design to assess the flexibility of breeding king penguin (Aptenodytes patagonicus) foraging behavior in response to harsh conditions at sea, and examined the consequences on the growth and survival of their chick. We tested for behavioral adjustments to compensate for experimentally increased foraging workload, obtained by the application of a hydrodynamic drag effect. Compared to controls, treated adults more directly targeted a predictable hydrographic feature, the Polar Front, while limiting the increased costs of deep diving. Treated adults significantly increased hunting activity at shallower depths where the effect of treatment on diving efficiency was negligible. Our experiment resulted in decreased body mass gain during the brooding stage of chicks raised by treated parents compared to controls, with no direct effects on chick survival up to the winter period, but significant negative effects during winter. We identified two different strategies for foraging in king penguins: (1) foraging at the Polar Front where prey patches are more predictable and accessible at shallower depths or (2) foraging closer to the colony by targeting preys at deeper depths. These results highlight the possibility of a trade-off between distance and depth in breeding king penguin foraging behavior.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 7","pages":"123"},"PeriodicalIF":2.3,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144560691","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}
