Using a suite of methods to account for rarity, dominance, and incomplete sampling, we aimed to determine how post-fire succession influenced locally rare and cryptic reptile species in semiarid mallee woodlands in southern Australia. Contemporary fires in this system are typically high-intensity wildfires or prescribed fires, which raze aboveground vegetation. Reptiles were sampled from pitfall traps over two summer seasons (1400 trap nights) at 14 sites spanning three fire history categories based on time since the last fire: recently burnt (2–3 years post fire), medium (7–9 years), and long unburnt (42–48 years). The data comprised 2138 individual reptiles from 41 species. The effects of fire history were evident in diversity metrics where proportional abundances were weighted toward rare species (Shannon's Diversity, Fisher's α), but not in those emphasizing common species (Simpson's Diversity, Berger–Parker Index) or species richness. There were no effects of fire history on the richness or abundance of locally rare species when examined directly. However, fire effects on rare species diversity were detectable in one sub-assemblage including 20 species with fewer than eight total observations. This result indicated higher diversity in unburnt habitat; an effect that was masked when numerically dominant species were included in the analysis. When accounting for incomplete sampling using rarefaction and extrapolation, unburnt habitat was more diverse, accumulated species more quickly, and required a greater sampling effort to obtain sample coverage comparable to recently burnt and medium habitat. Overall, common and abundant reptile species appeared to dominate recently burnt and mid-succession habitats, while reptile communities in long unburnt habitat were more diverse because they had more rare or cryptic species. The data suggest that responses of rare species to fire history are harder to detect than common, dominant species which are often favored by disturbance (and scientific research). Fire management which maintains some early- and mid-successional habitat, while strategically conserving unburnt habitat, should benefit rare and cryptic reptile species in this system.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"106 6","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.70121","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144336093","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}

Niche compression occurs when species reduce resource use due to competition, and niche complementarity posits resource competition should occur sequentially among habitat, time, and food. Within this context, interspecific predator competition can be influenced by prey characteristics and landscape attributes. We examined drivers of interspecific competition among carnivores using a database of North American ungulate cause-specific mortality published during 1970–2021. We used weighted logit-linked beta-binomial generalized linear mixed models to assess the influence of seven predator species, ungulate age class, and landscape characteristics (i.e., human footprint, terrain ruggedness, and forest cover) on ungulate predation mortality. We predicted that (1) predation by individual predator species would decrease with increasing predator species richness mediated by predator size, (2) landscape characteristics would mediate predation by individual predator species, and (3) juvenile ungulate predation would increase with increasing predator species richness. As predator species richness increased, the proportions of predation attributed to individual predator species decreased, but the overall proportion of ungulate mortality attributed to predation increased. Juvenile ungulates experienced greater predation mortality than adults, with smaller predators predating proportionally more juveniles than larger predators. Landscape metrics altered observed predation patterns among caribou (<i>Rangifer tarandus</i>), wherein predation corresponded to terrain ruggedness but not predator species richness, and mule deer (<i>Odocoileus hemionus</i>), wherein predation increased with greater forest cover. We provide evidence for niche compression and complementarity using a top–down predator-centric approach by showing compression in prey resources and increased predation mortality with increasing predator species richness. However, landscape characteristics had limited effects on predator competition at large spatial extents, which counters niche complementarity. Collectively, our results support the importance of large predators to ecosystem structure and efforts to conserve and restore predator guilds.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"106 6","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.70136","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308944","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 the Gulf of Mexico, our 8-year study captured two disturbances that had contrasting effects on predator abundance and cascading effects on estuarine food webs. In 2017, Hurricane Harvey destroyed fishing infrastructure, fishing activity declined, and sportfish populations increased ~40% while intermediate trophic levels that sportfish prey upon declined ~50%. Then, in 2021, a fish kill caused by freezing temperatures during Winter Storm Uri reduced sportfish populations by ~60% and intermediate trophic levels increased by over 250%. Sportfish abundance affected the abundance and size of oyster reef mesopredators. Excluding fish predators significantly altered oyster reef community structure. These results demonstrate how extreme events shape communities and influence their resilience based on their effects on top predators.

Animals use behavior to prevent these harmful physiological states, but their need and ability to do so varies with their traits. Within species, traits such as sex and reproductive status affect heat sensitivity, perhaps eliciting differences in behavioral responses to thermal extremes. We evaluated whether sex and reproductive status affected thermoregulatory behavior and its efficacy in moose (<i>Alces alces</i>), a heat-sensitive endotherm that relies on thermal refuge. We expected traits associated with elevated heat load would be linked to heightened selection for thermal refuge and that differences in selection would successfully alleviate differing risks of overheating. Thus, reproductive females and males, who are more heat-sensitive, would have stronger selection for thermal refuge than non-reproductive females. We assessed selection of thermal refuge at bed sites and generated biophysical models to evaluate if selection mitigated risk of overheating. Reproductive status did not elicit differences in selection by females. The sexes, however, differed in selection of the trade-off between solar cover and cooling from wind. Females selected refuge with canopy cover and avoided wind. Males did not select cover and had weaker avoidance of wind than females. Yet, both sexes were more likely to overheat in areas of low cover, even if wind speeds were high. Hence, males had weaker selection of refuge than females despite being more likely to overheat, and life history trade-offs failed to explain the sub-optimal thermoregulatory behavior.

The European bee-eater <i>Merops apiaster</i>, an aerial-foraging insectivorous bird, breeds gregariously by digging tunnel nests at a sufficient depth underground to mitigate the impact of surface temperature (Casas-Crivillé & Valera, <span>2005</span>; White et al., <span>1978</span>). Additionally, substrate quality is crucial, requiring soils that are soft enough to be excavated yet firm enough to prevent nest collapse (Heneberg & Šimeček, <span>2004</span>; White et al., <span>1978</span>).</p><p>Doñana is located in the SW of the Iberian Peninsula (Figure 1a) and is mainly composed of two large flat environments: a seasonal freshwater marshland on clayey soils and an extensive system of eolian dune fields hosting Mediterranean woodlands and scrublands (Valverde, <span>1963</span>). This area includes Doñana National Park, where the European bee-eater has historically been a common nester along the ecotone between marshes and eolian dune fields (locally known as <i>La Vera</i>), on sandy islands within the marshes, and occasionally in other locations, such as the bottom of dry seasonal ponds (Valverde, <span>1960</span>; Figure 1b). In all these environments, the mixture of sandy and clay soils provides a suitable substrate for nest excavation. Historical records in the field notebooks of Doñana's ornithologists report bee-eater breeding colonies in the National Park and two Special Protection Areas (known as <i>El Acebuche</i> and <i>La Rocina</i>). During the 30-year period between 1970 and 1999, 17 colonies (ca. 77% of the colonies) and 1543 nests (ca. 87%) were recorded in the ecotone.

In the Mediterranean Sea, the world's largest warm-temperate sea, the endemic, colonial, and zooxanthellate scleractinian coral <i>Cladocora caespitosa</i> builds reefs, with growth rates exceeding 5 mm year<sup>−1</sup> and calcification rates reaching 1.7 kg CaCO<sub>3</sub> m<sup>−2</sup> year<sup>−1</sup>, similar to many tropical reef corals (Anderson et al., <span>2017</span>; Morri et al., <span>2000</span>). Fossils of reefs formed by this species are known from warmer climatic phases of the Quaternary (Aguirre & Jiménez, <span>1998</span>; Peirano et al., <span>1998</span>). Today, colonies may occur in isolation or as free-living nodules (coralliths), but when abundant, they may form beds made up of numerous sub-spherical colonies in dense populations or banks, that is, large structures reaching several decimeters high and covering areas of several square meters (see Bianchi et al., <span>2021</span>, for a recent synthesis; a list of key references on these formations and their ecology is provided in Appendix S1: Section S1).</p><p>Here, we report on a novel type of large living formation of <i>C. caespitosa</i> found at Torre delle Stelle (39.141143° N, 9.401533° E), off southeastern Sardinia (Italy, western Mediterranean Sea), about 1 km outside the western border of the Capo Carbonara Marine Protected Area. The bioconstruction occurs at the entrance of a bay characterized by a relatively flat sandy bottom, large granitic boulders, and <i>Posidonia oceanica</i> meadows. Unlike the four above-mentioned coral formation types (isolated colonies, free-living coralliths, beds, and banks), which all develop on horizontal to gently sloping substrates, the present formation has developed on a vertical wall, with colonies growing outward in parallel. Smaller similar bioconstructions on vertical substrata were described from the Columbretes Islands, Spain (Kersting & Linares, <span>2012</span>).</p><p>This peculiar coral formation is located about 25 m from the shoreline, starting on the top of a massive granite rock at 7.7 m depth and developing down to 9.8 m depth. Its maximum horizontal and vertical axes reach ~2.7 and 2.1 m, respectively, with ~0.4 m maximum thickness. The formation covers >5 m<sup>2</sup> and features a complex three-dimensional structure (Figure 1). The bioconstruction health status is relatively good, except for old necrosis signs on the top of the formation (Figure 1a) and a few localized small areas with recent necrosis, dwindled polyps, budding, or encrusted dead corallites (Appendix S1: Figure S1).</p><p>The formation has a regular periodic pattern of subequal horizontal ledges of increasing width, formed by bracket-like sub-horizontal colonies that grow outward parall","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"106 6","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.70097","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273202","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}

Lepidopterans include striking mimics of aposematic hymenopterans. Imitations may include not only visual components, but also acoustic and chemical signaling. We evaluated whether hymenopteran-mimicking clearwing moths (Lepidoptera: Sesiidae) and diurnal hawkmoths (Lepidoptera: Sphingidae) complement visual anti-predator signaling with acoustical mimicry. Through field-based experiments, we then compared the response of an avian predator, the European robin (<i>Erithacus rubecula</i>), to hymenopteran models and their lepidopteran mimics. Our work contradicts the assumption that aposematism and Batesian mimicry provide generalized protection to insects, paving the way for comparative studies involving a broader range of predators. We verified two predictions: (1) robins discriminate among different models based on their perceived risk, with avoidance behavior occurring in response to more harmful stimuli; (2) predators respond similarly within each studied pair of model and mimic. We demonstrated a clear distinction in the reaction of robins to the hornet <i>Vespa crabro</i> and its mimic, the hornet clearwing <i>Sesia apiformis</i>, in comparison to all other tested species, strongly indicating that the presence of the hornet and hornet mimic deterred the birds.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"106 6","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273203","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}
