However, the availability and reliability of carrion differs across environments. Modified landscapes, such as farms and roads, often produce a high density of carcasses, with disproportionate benefits for generalist mesoscavengers that can tolerate, or are attracted to, human presence. In this study, we placed carcasses strategically across two large islands in southern Australia and used camera traps to investigate how different scavengers locate and use carrion in forested, farmland and roadside habitats. Forest ravens, an avian generalist, were the dominant scavengers across all three habitat types but were three times more likely to discover carcasses deployed in modified landscapes. Raptors were twice as likely to discover and use carcasses in farmland habitats, indicating enhanced scavenging opportunities in these areas. The discovery rate and use of carcasses by feral cats did not differ between habitat types. In this setting, differences in carrion use between diurnal and nocturnal scavengers are potentially due to the absence of top mammalian carnivores (Tasmanian devils and quolls). Diurnal scavengers, such as forest ravens and raptors, followed expected habitat preferences, albeit with greater access to carrion due to increased persistence. However, feral cats demonstrated no preference for carcasses across habitats, likely due to the reduced landscape of fear. Overall, our study underscores the important role of native mammalian carnivores in structuring scavenger communities and further validates the value of trophic rewilding to restore key ecological functions.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 4","pages":"60"},"PeriodicalIF":2.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780708","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}

We used lichens to assess patterns of Ndep amounts and chemistry at North Cascades National Park Service Complex ('North Cascades') and Olympic National Park ('Olympic'). Lichen %N indicate rates of Ndep below N critical loads; our results contrast with air quality models that predict critical load exceedance in many areas. Lichen δ15N indicated a dominance of reduced N in Ndep suggesting significant contributions from NHx emission sources. Lowland areas adjacent to urban corridors exhibited the highest proportions of reduced N in Ndep. Current policies target oxidized N from fossil fuel combustion, but not reduced N, causing an increase in the reduced:oxidized ratio in Ndep. Species-specific responses to these changes could alter biodiversity, community structure, and ecosystem processes over time. Our study underscores the importance of fine-scale assessments of Ndep and deposition chemistry, particularly in ecologically sensitive mountainous regions.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 4","pages":"59"},"PeriodicalIF":2.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780707","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}

The latter is important because many bat species benefit from social thermoregulation by forming colonies in their roosts. However, it remains unclear whether bats can base their roost choice directly on the space available for roosting when other characteristics, such as roost microclimate do not vary. We present results from a field experiment in which RFID-tagged Bechstein's bats (Myotis bechsteinii) in a maternity colony were given paired bat boxes with identical external dimensions but differing internal roosting space. This allowed us to control for other factors that might influence roost choice and to record the bats' nightly visits to the boxes prior to their occupation as day roosts. To assess whether roost temperature influenced roost choice in our setup, we measured the internal temperature of the boxes. Female Bechstein's bats showed a clear preference for boxes with more roosting space, as evidenced by a higher frequency of nightly visits and more frequent use as day roosts. As there was no significant difference in temperature between boxes with different internal volumes, roost temperature cannot explain the bats' preference for spacious roosts in our experiment. Our data provide evidence that bats can directly assess the volume of their roosts. Our results are consistent with the argument that small volume roosts may limit roosting group size potentially reducing social thermoregulation benefits.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 4","pages":"58"},"PeriodicalIF":2.3,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11965151/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143773026","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}

Preferred body temperatures (PBT) and thermal performance curves (TPCs) are comprehensive thermal physiology traits reflecting overall physiological performance and crucial for predicting species-specific responses to environmental changes. There is limited or conflicting information on how food availability affect the PBT and TPCs of lizard species, despite their significance in the context of the global decline in reptile species. The aim of this study was to experimentally investigate how food deprivation affects the PBT and TPCs of the European green lizards (Lacerta viridis). We exposed 30 adult male European green lizards to optimal and suboptimal food treatments. We assessed PBTs, and characterized the TPCs based on the thermal optimum (To), the maximum performance (Pmax) and performance breadth (B80) of the lizards. We found that food availability had a significant impact on preferred body temperature and locomotor performance. Lizards experiencing suboptimal conditions showed a preference for lower body temperatures, indicating an intention to minimize energy expenditure during fasting. Additionally, food-deprived lizards had wider B80 range, suggesting their thermal acclimatization to maintain effective performance across a broader temperature range. Our findings highlight the importance of food availability as a key environmental stressor influencing thermoregulation strategies. As habitat modifications and global warming continue, it is crucial to evaluate the impacts of these changes on species for the development of effective conservation strategies.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 4","pages":"57"},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11961467/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143753735","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}

Metabolic scaling theory integrates the size-metabolism relationship, yet most research overlooks intraspecific trait variation due to ontogeny. Specific leaf area (SLA) is a critical functional trait that reflects investment on photosynthetic tissues relative to leaf construction costs. SLA influences photosynthetic capacity and growth rates and varies across life stages. While plants exhibit interspecific differences in acquisitive (high SLA, fast growth) and conservative (low SLA, slow growth) strategies, the diminishing returns hypothesis suggests that these strategies are shaped by the proportion of supporting structures that develop over the plant´s lifespan (intraspecific variation), predicting a negative SLA relationship with increasing size. In tropical environments, palms are ecologically important yet still understudied in functional traits. Here, we examine the relationship between SLA and size in six neotropical understory and canopy palm species (236 individuals). Results showed higher SLA in understory species and a negative SLA-size relationship across most species. SLA inversely correlated with leaf thickness and leaf water content. ANCOVA models explained substantial SLA variation related to palm size, with species-specific differences in regression slopes. These findings underscore the importance of considering inter- and intraspecific SLA variation and ontogenetic changes. Understanding the trade-off between acquisitive and conservative strategies within the context of the diminishing returns hypothesis offers insights into plant growth strategies and their ecological implications, which is essential for predicting plant adaptation to environmental gradients.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 4","pages":"56"},"PeriodicalIF":2.3,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736092","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}

However, few studies have evaluated whether and by which pathways floral trait dissimilarity affects interspecific pollen transfer among co-flowering species, which limits our understanding of the interplay between mutualistic and competitive interactions within plant-pollinator networks. We conducted a three-year field investigation from 2021 to 2023 in a sub-alpine meadow in southwest China. We observed plant-pollinator interactions and identified pollen grains on the stigmas of co-flowering species to construct plant-pollinator visitation networks and heterospecific pollen transfer (HPT) networks. We also measured 18 floral traits across 44 co-flowering species, categorizing these traits into attractant traits (flower color spectra, corolla morphology) and reproductive traits (male and female organs). By calculating the dissimilarities in each floral trait category between species pairs, we conducted structural equation modeling to link the dissimilarities in floral traits between species pairs with pollinator sharing and HPT. Our results demonstrated that dissimilarities in flower color and corolla morphology significantly reduced pollinator sharing, and indirectly decreased HPT. Conversely, the dissimilarities in male and female-organ traits did not have a significant impact on HPT or pollinator sharing. Our findings support the theory that divergent floral traits help reduce interspecific competition, highlighting the adaptive significance of floral trait divergence in plant-pollinator interactions.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 4","pages":"55"},"PeriodicalIF":2.3,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143677138","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}

Texture is controlled by dry matter, water and air contents. Our aim was to a) identify the best index of succulence, b) assess how these three components vary with leaf type, and c) derive bounds for these properties among the four main leaf-texture classes. Eight contrasting species from the Namib Desert, South Africa were assessed for their leaf area (A), thickness (z), dry mass (D), saturated water content (Q), and relative volume of dry matter, water and air to derive various indices of leaf texture. Q/A (= QV•z), where QV is saturated water storage per unit volume of leaf and z is leaf thickness is an ideal index of succulence. Specific leaf area (SLA) is more suitable as an index of hardness (SLA-1 = D/A) but only among non-succulents. Rising leaf specific gravity among sclero-orthophylls is due to replacement of air by dry matter but water among succophylls. Collation of 13 worldwide studies showed that orthophylls can be distinguished by a Q/A ≤ 0.45 mg water mm-2 leaf surface from succophylls with Q/A ≥ 0.9, such that there is a divergent relationship among plants regarding their water-storing properties. Semi-succophylls can be defined as having a Q/A > 0.45 to < 0.9, and sclerophylls can be separated from orthophylls by a SLA ≤ 10 mm2 mg-1 dry mass. The distribution of these leaf texture classes may vary greatly within, and especially between, local floras.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 4","pages":"54"},"PeriodicalIF":2.3,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11926024/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143670512","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}

Less is known about seasonal changes in evaporative water loss (EWL) in response to changing water availability and humidity. The wet-dry tropics of northern Australia experience moderate seasonal temperature changes, but substantial changes in rainfall and humidity. We studied three gecko species (Amalosia rhombifer, Heteronotia binoei and Hemidactylus frenatus) in the wet and dry seasons with respect to their EWL, preferred body temperatures (Tpref), and their choice between a dry and humid refuge at and below Tpref. EWL was significantly lower in the dry season (66% of wet season values). Tpref for two of the species did not change seasonally, but A. rhombifer selected lower Tpref during the warmer wet season. Given a choice of refugia, the humid refuge at low temperatures was never preferred over the warm microhabitat. When both refugia were at the preferred temperature, only A. rhombifer showed a preference for the humid microhabitat. These results demonstrate that although thermoregulation is prioritised in the short term, hydroregulation (physiological plasticity in EWL) is adjusted in the longer term, with shifts occurring on a seasonal scale. However, it is possible that shifts in EWL may occur in response to prevailing weather conditions on a shorter timescale. Before broad generalisations can be drawn about the phenomenon of EWL plasticity, measurements need to be taken from more species in different climatic regions at ecologically relevant timescales.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"207 3","pages":"53"},"PeriodicalIF":2.3,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11909027/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143630638","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}

Continued forest fragmentation in the region will result in increased edge effects, and a greater proportion of forest remaining in an early successional state, leading to a highly reduced, homogenized, amphibian and reptile assemblage.

We found local adaptation in developmental traits, with low-altitude populations being adapted to warmer temperatures and longer seasons. Lycaena tityrus responded negatively to agriculturally relevant levels of fertilization of its host plant, showing reduced body mass and prolonged development time. Negative effects were particularly pronounced at warmer temperatures and in high-altitude populations. Our study adds to the increasing knowledge that different drivers of global change may interact and thereby increase the overall level of threat to biodiversity.
