However, risk effects on prey traits and fitness are often modulated by other ecological factors, such as food resources. While few studies explicitly link antipredator responses with prey fitness, even fewer examine the influence of food resources on the strength and direction of nonconsumptive effects (NCEs). To understand the mechanistic underpinnings of NCEs and how resource abundance modulates them, we measured multiple antipredator responses and fitness in wild Indian spiny-tailed lizards <i>Saara hardwickii</i> in natural environments that varied in both predation risk and resource abundance. Specifically, we measured behavioral (flight initiation distance (FID), total hiding duration, and foraging range) and physiological (stress-induced glucocorticoid levels) responses of lizards in four patch types—(1) high risk–high resource, (2) high risk–low resource, (3) low risk–high resource, and (4) low risk–low resource. We also measured body condition (scaled mass index) and number of offspring for lizards inhabiting all four patch types. Using a structural equation modeling approach, we examined the mechanistic links between specific antipredator responses and prey fitness and tested whether these links were amenable to changes in resource levels. We found that predation risk affected behavioral, but not physiological, responses such that lizards in high-risk habitats had shorter FIDs and foraging ranges, and longer hiding durations. In resource-poor habitats, risk-induced changes in prey behavior adversely affected food intake, resulting in lower body condition and fewer offspring. By contrast, where resources were abundant, individuals in high-risk habitats maintained their food intake, with no negative effects on body condition and fitness. To maintain similar food intakes, individuals in low-risk–low-resource areas foraged for longer durations and distances compared to those in low-risk–high-resource areas. Overall, we show that while predation risk significantly influences prey traits, resource availability can determine the cost of these NCEs. By measuring multiple responses, our findings provide mechanistic insights into how habitat conditions can interact with the landscape of fear and give rise to variable fitness outcomes in heterogeneous environments.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 10","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149130576","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}

Chan","doi":"10.1002/ecy.70540","DOIUrl":"10.1002/ecy.70540","url":null,"abstract":"&lt;p&gt;Charles Darwin, who devoted many years to the study of barnacles, once remarked that “Cirripedes now abound so under every zone, all over the world, that the present period will hereafter apparently have as good a claim to be called the age of Cirripedes as the Palaeozoic period has to be called the age of Trilobites” (Darwin, &lt;span&gt;1851&lt;/span&gt;). Thoracican barnacles are among the most versatile colonizers in the marine realm, occupying a niche breadth that spans from high-intertidal rocks to deep-sea hydrothermal vents. Their success is rooted in an extraordinary plasticity for substrate selection (e.g., Figure 1); they encrust everything from driftwood and ship hulls to the living tissue of crustaceans, sea turtles, and cetaceans (Chan et al., &lt;span&gt;2009&lt;/span&gt;; Pilsbry, &lt;span&gt;1916&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;While marine mammals, namely, whales and dolphins, are described as “moving islands” commonly colonized by epibionts including barnacles (Geraci &amp; Aubin, &lt;span&gt;1987&lt;/span&gt;). Fishes, however, are among the few animal groups on which barnacles do not commonly occur, possibly due to the protective mucus layer of fish skin (Balakrishnan, &lt;span&gt;1969&lt;/span&gt;). Species of &lt;i&gt;Conchoderma&lt;/i&gt;, the stalked barnacle typically associated with floating substrates and crustaceans (including parasitic copepods and isopods), have nonetheless been recorded from several fish species, where it reportedly attaches to spines, areas of damaged skin, or in the mouth of fishes (Anislado-Tolentino et al., &lt;span&gt;2021&lt;/span&gt;; Hastings, &lt;span&gt;1972&lt;/span&gt;). Similarly, &lt;i&gt;Lepas anatifera&lt;/i&gt; has been documented on the damaged skin of a stranded sunfish, &lt;i&gt;Mola mola&lt;/i&gt; (Barreiros &amp; Teves, &lt;span&gt;2005&lt;/span&gt;). The occurrence of &lt;i&gt;Platylepas decorata&lt;/i&gt; on the scales of a garpike remains the only documented case of a sessile barnacle recorded from a fish host (Ryder, &lt;span&gt;1879&lt;/span&gt;). Seilacher (&lt;span&gt;2005&lt;/span&gt;) postulated that the acorn barnacle species evolved specialized anchoring mechanisms and host-specific adaptations that allow them to settle and colonize living hosts. Similarly, &lt;i&gt;Anelasma squalicola&lt;/i&gt;, a naked stalked barnacle, represents a highly specialized parasitic form that attaches to deep-sea sharks that predominantly attach to the dorsal or pectoral fins in an area where the skin is thinner, or turbulence may facilitate attachment (Eliassen, &lt;span&gt;2016&lt;/span&gt;; Ste-Marie et al., &lt;span&gt;2023&lt;/span&gt;). While ectoparasites are commonly recorded as occurring on the skin of skates in the Atlantic (superorder: Batoidea) (Boxshall, &lt;span&gt;1974&lt;/span&gt;), to our knowledge, there is no documented observation of any barnacle species colonizing skates (Family: Rajidae) to date.&lt;/p&gt;&lt;p&gt;The flapper skate, &lt;i&gt;Dipturus intermedius&lt;/i&gt; (Parnell, 1837) is the largest skate recorded in the North Atlantic, reaching over approximately 2.5 m in total length (Last et al., &lt;span&gt;2016&lt;/span&gt;).

Yet predicting how species will respond is difficult due to a complex interplay of scale-dependent factors. For understudied taxa in relatively inaccessible boreal regions, it is particularly challenging to disentangle the drivers of species distributions. Here we utilized an integrated framework to better understand the relative importance of climate and microhabitat in shaping species distributions at different spatial scales. This framework combines landscape-scale generalized linear models of species occurrence with local-scale Bayesian causal structural equation occupancy models. We tested this approach on two understudied alpine species with differing life history strategies—collared pikas (<i>Ochotona collaris</i>) and hoary marmots (<i>Marmota caligata</i>)—in Denali National Park and Preserve, Alaska (USA). While both species are projected to be sensitive to climate change, considerable uncertainty exists regarding the specific climatic factors and underlying mechanisms driving these impacts. At the landscape scale, we modeled 63 pika and 33 marmot detections and found that species occurrence was negatively linked to warmer summers and shrub-encroachment (marmots only) and positively linked to slope, colder and wetter winters (marmots only), and stable snowpack insulation (pikas only). We incorporated these predictors into structural equation occupancy models with occurrence data from 83 sites to tease apart climatic relationships and tested additional occupancy models of microhabitat conditions. At local scales, we found support for microhabitat influencing the occurrence of pikas, with occupancy positively related to talus rock size, but an inconclusive effect of climate on pika occupancy and inconclusive support for all predictors on marmot occupancy. These results are consistent with distributions of both species being constrained by climatic factors at a landscape scale, with pikas additionally limited by local microhabitat conditions. For pikas, these hierarchical constraints highlight the importance of incorporating local, environmental conditions within broad-scale climate models and suggest that large, rocky talus may confer pikas greater resilience to climate pressures than suggested by broad-scale models alone. Overall, our study provides a versatile framework for analyzing the diverse and multi-scale impacts of climate change on species.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 10","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087460","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 found that the effects of soil conditioning and physical sheltering from CWM each contributed to spatial variation in plant composition, separately. The presence or absence of CWM in the immediate vicinity of plants explained about 10% of the variation in community composition and had a significant, species-specific effect on germination and biomass for all three focal species. A larger proportion of variation (~50%) in plant assemblages was explained by the broader-scale spatial unit of experimental blocks, suggesting that broader-scale environmental factors have a greater impact on species composition in these communities than the very localized fine-scale impacts of CWM (~10%). Our study provides empirical evidence that species-specific responses to spatial heterogeneity align with spatial variation in community composition, consistent with the prerequisite necessary for the operation of spatial coexistence mechanisms.

This is especially true for vectors that transmit human pathogens. However, studies investigating the effects of environmental variation on vectors have typically investigated environmental factors in isolation or in laboratory experiments that examine constant environmental conditions that often do not occur in the field. To address these limitations, we conducted a semi-field experiment in Athens, Georgia, using the invasive Asian tiger mosquito (<i>Aedes albopictus</i>). We selected nine sites that varied in impervious surface and vegetation cover to explore effects of natural variation in microclimate (specifically, temperature, and relative humidity) on mosquitoes. We manipulated conspecific larval density at each site and repeated the experiment in summer and fall to further increase the variability in temperature and relative humidity. We then evaluated the original design features (land cover, larval density, and season), and their interactions, on the mean proportion of females emerging, juvenile development time, size upon emergence, and estimated per capita population growth (i.e., fitness). We found significant effects of larval density, land cover, and season on all response variables, including a non-intuitive decrease in development time with increasing larval density in fall. We repeated these analyses using the hypothesized microclimate drivers of these effects: temperature and relative humidity. In general, the model using the microclimate variables outperformed the model using land use and season, highlighting the roles of temperature and relative humidity and their interactions with density on mosquito traits and dynamics. Our study demonstrates that ignoring the interaction between variation in biotic (e.g., intraspecific competition) and abiotic (e.g., temperature and relative humidity) variables could reduce the accuracy and precision of models used to predict mosquito population and pathogen transmission dynamics, especially those inferring dynamics at finer spatial scales across which transmission and control occur.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 10","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.70521","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087504","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}
