Bromeliads (Bromeliaceae) are classic examples, as their leaf axils provide suitable habitats for bacteria, algae, protozoa, invertebrates and vertebrates, including anurans. Frogs associated with bromeliads are classified as bromelicolous when they use these plants occasionally, or bromeligenous when they complete their life cycle within them. Such associations may facilitate dispersal mechanisms, including phoresy, in which organisms are passively transported by animals. During a herpetological expedition in Mucugê Municipal Park, Bahia, individuals of <i>Scinax montivagus</i> were observed carrying ostracods of the genus <i>Elpidium</i>. This constitutes the first record of phoresy for this anuran and evidence of its association with bromeliads. Although frogs were collected near a water body, the presence of <i>Hohenbergia caatingae</i> bromeliads nearby strongly suggests that ostracods were transported from these plants. This finding expands current knowledge of bromeliad–vertebrate interactions, particularly regarding ostracod dispersal by frogs, previously documented only in the Atlantic Forest and now also recorded in the Cerrado. It further raises the hypothesis that frogs may mediate ostracod dispersal not only among bromeliads but also into other aquatic habitats, potentially contributing to colonization across heterogeneous landscapes. Our results highlight the ecological complexity and functional importance of bromeliad-associated systems, emphasizing the role of dispersal in population dynamics and habitat connectivity, and underscore the need for further studies on these multi-species interactions and their implications for Neotropical biodiversity conservation.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"51 5","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70227","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148068419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Consequently, our understanding of behavioural ecology is shaped by such biases, even though these studies have provided important insights. Rarer or more cryptic behaviours, especially in historically neglected taxa, can nonetheless reveal key aspects of ecological and evolutionary dynamics. One such underexplored phenomenon involves nesting associations between social wasps and ants. Here we present the first photographic and video documentation of <i>Agelaia pallidiventris</i> nesting within a <i>Azteca</i> ant nest in the Brazilian Amazon. The wasps occupied chambers inside the ant nest through three circular openings, coexisting without visible aggression. The observation suggests a stable, possibly mutualistic association. This finding provides unprecedented evidence of an intimate wasp–ant nesting relationship and highlights the need for renewed natural history research. Understanding whether such interactions are commensal (e.g., where wasps gain passive protection from the ants' territoriality), parasitic (e.g., cleptoparasitism), or mutualistic (e.g., a defence system against shared predators) will illuminate the selective pressures shaping behavioural evolution in Amazonian insect communities.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"51 5","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70226","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148064786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Understanding the threats to and risk status of alpine and subalpine ecosystems is vital to guide their conservation, inform monitoring programs and identify the relative impact of activities currently degrading these ecosystems. We applied the IUCN Red List of Ecosystems criteria to 15 alpine and subalpine ecosystem types across Australian mountains. We found that seven ecosystem types were classified as threatened and three as Near Threatened, together accounting for 83% of the alpine and subalpine region. The primary threats were climate change and associated changes in fire regimes. There were insufficient data to quantify the environmental or biotic integrity of six ecosystem types, and one ecosystem type was listed as Data Deficient overall. Our study highlighted key knowledge gaps in the integrity of alpine and subalpine systems that limited our capacity to reliably assess risk to these ecosystems. We recommend expanding on-ground monitoring of ecosystem integrity to improve understanding of risks, key threats and actions to mitigate them. To reduce risks to these ecosystems, climate change must be aggressively mitigated, collateral pressures from invasive plants and animals must be reduced, and critical knowledge gaps that will allow conservation action prioritisation must be quickly filled. These strategies should be co-ordinated, resourced and enacted urgently in cross-jurisdictional Alps-wide work plans.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"51 5","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148095937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

We evaluated the efficiency of three frog sampling methods (active search, plot sampling, and pitfall traps) across Atlantic Forest remnants to estimate species richness and abundance of forest-specialist species during rapid assessment surveys. We also examined the effectiveness of these methods in assessing the influence of forest cover on different functional groups of frogs: water-dependent and water-independent species. Across 146 sampling days, we recorded 1450 individuals from 53 species. Active searches yielded the highest species richness (50 species), surpassing plot sampling (18 species) and pitfall traps (16 species). Active search was more efficient than plot and pitfall methods for estimating richness, while active search and plot were more efficient than pitfall traps for estimating abundance. Among the statistically significant models assessing the effects of forest cover on estimated richness, the highest fits were obtained for models that used data from the three methods combined (90% of the variance) or active search combined with pitfall (88%). For water-dependent species, the models that provided significant results with highest fits used data from the three methods combined (93%) or active search combined with pitfall traps (92%). Active searches combined with plot sampling improved detection of forest cover effects on frog abundance (60%), mainly for water-independent species (71%). Richness of water-dependent species had stronger sensitivity to forest loss, while water-independent species had abundance declines associated with forest loss. Despite being labor-intensive, pitfall traps uniquely detected rare taxa, emphasizing their complementary role. For rapid assessments, we advocate for integrating active searches with targeted passive methods, as prioritizing multi-method approaches combined with functional trait analyses can enhance the detection of ecologically distinct groups and generate more robust data to guide biodiversity conservation efforts.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"51 5","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70223","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148095380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

We present the first continental-scale assessment of climate-driven range shifts for cave-dwelling bats in sub-Saharan Africa, using <i>Miniopteridae</i> as an obligate cave-dependent model taxon, by integrating species distribution models with a validated karst-based roost suitability layer and a landscape-stability index reflecting projected land-cover vulnerability. Using 551 curated occurrence records, MaxEnt models under six CMIP6 climate scenarios projected substantial range contractions of 36%–64% by 2061–2080, with future suitability restricted mainly to southern Africa, the eastern highlands, and Madagascar. Geological constraints further limited persistence: only ~5% of roost-suitable karst overlapped with future climatically suitable areas, and this overlap decreased to ~2% after weighting for land-cover vulnerability. Similarity metrics revealed extremely low spatial congruence between roost availability and stable climatic refugia. Migration ecology suggests that fragmentation of seasonal roost networks may further hinder persistence by disrupting movement corridors and increasing energetic costs. Collectively, these results show that long-term persistence of cave-dwelling species like <i>Miniopteridae</i> will depend on conserving climate–karst refugia and maintaining connectivity between seasonal roosts.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"51 5","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70224","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148095383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
