Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co-occurring invaders jointly influence pollination networks. We leveraged the relative simplicity of the Ogasawara archipelago to assess the combined impacts of multiple invaders on pollination networks. We surveyed floral and pollinator communities and quantified plant-pollinator interactions across four islands with varying degrees of invasion. We characterized invasion degree based on the abundance of three invasive taxa: green anoles (Anolis carolinensis), a predator; western honey bees (Apis mellifera), a floral competitor; and several flowering plants. Structural equation models were used to quantify direct and indirect effects of these invaders on effective plant-pollinator partners (niche breadth or variety of partners a species interacts with in a given community) and the degree of specialization (d', niche partitioning or selectivity of a species) of plant and pollinator communities. All invaders strongly affected pollinator diversity and, to a lesser extent, plant diversity. Anoles had the strongest negative effect on pollinator diversity, triggering cascading effects across the trophic chain. Directly or indirectly, all invaders negatively affected plant resource use. Honey bee abundance had a direct negative effect on plant effective partners and specialization, and anole abundance and the proportion of invasive plants indirectly affected plant resource use through a reduction in pollinator diversity. Degree of invasion and network structure mediated whether honey bees contributed to functional compensation or facilitated invasional meltdown. Our findings demonstrated that co-occurring invaders generated synergistic pressures on pollinators and plants, underscoring the importance of evaluating invasions in a multistressor context. Integrative approaches are essential for developing conservation strategies in vulnerable ecosystems, particularly oceanic islands, where biological invasions are the principal driver of biodiversity loss.</p>","PeriodicalId":10689,"journal":{"name":"Conservation Biology","volume":" ","pages":"e70304"},"PeriodicalIF":5.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13613568/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147764887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Botswana's Kalahari hosts one of sub-Saharan Africa's largest unprotected areas supporting free-ranging wildlife. The role of multiuse areas as a wildlife habitat and movement corridor is increasingly threatened by land-use change, particularly the expansion of sedentary livestock farming. In light of these changes, updated information on wildlife status and their use of these areas is lacking. Leveraging the Kalahari's sandy substrate and Indigenous tracking skills, we demonstrated the potential of animal track surveys for large-scale wildlife monitoring. We conducted biannual surveys over 3 years across 22,000 km² of multiuse wildlife management areas and used the Formozov-Malyshev-Pereleshin formula approach-a population density estimator-to collect large herbivore and carnivore track data. We analyzed 22,793 tracks from 13 species collected over 6222 km of transects with three objectives: estimate species population densities, identify key environmental predictors of their spatial variation, and derive predictive maps to highlight higher wildlife density areas. Although some herbivores declined, no changes in carnivore densities were detected over the study period. Cattleposts were negatively associated with most species, whereas burned areas showed contrasting associations with herbivore and carnivore densities. Vegetation characteristics and distance to mineral pans were also often associated with species density. The region still supports large wildlife and potential movement pathways-albeit less than in the past-especially away from human activity. We identified key areas for preservation in future land-use planning, with potential to also support nature-based livelihood development. Where tracking substrates and Indigenous knowledge coexist around the world, track-based monitoring can effectively inform conservation. Its cultural and economic benefits to local communities, in addition to relational engagement with the natural world, may also contribute to human-wildlife coexistence, uphold land rights, and support community-led resource management.</p>","PeriodicalId":10689,"journal":{"name":"Conservation Biology","volume":" ","pages":"e70397"},"PeriodicalIF":5.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149105269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Based on a pan-European database for occurrence and abundance of breeding birds collected in the 2010s, we applied the Zonation algorithm to identify key areas that would maximize the protection of ranges and populations for 435 species of breeding birds across Europe using either continental or national prioritization targets.

When 10% and 30% of the highest priority lands were selected, compared with prioritization using occurrence data, prioritization using abundance data resulted in a higher percentage of species' populations, especially rare and range-restricted species, being represented for protected area coverage. Stratifying prioritization by habitat criteria greatly enhanced habitat-specific conservation efficiency, enabling coverage of over 80% of breeding bird species' populations in tundra, Mediterranean, and coastal habitats with a selection of 10% of the highest priority areas for each.

We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator. We applied this approach across five broad benthic habitat types in the Bay of Biscay and the Gulf of Cádiz, two regions that are subject to substantial trawling pressure. Using data from over 2000 monitoring locations, we assessed habitat sensitivity to trawling through generalized additive models (GAMs) and the SoS indicator, which quantifies benthic habitat quality based on the proportion of sentinel species (i.e., species typical of the habitat and sensitive to the pressure). We also sought to establish scientifically grounded quality thresholds to assess bottom-trawling impacts by applying three complementary approaches: distance to degradation, natural variation, and detectable change. We conducted a temporal analysis to evaluate changes in trawling impacts over time. Impact assessments varied depending on the method used to determine thresholds, although the natural variation and distance to degradation approaches yielded consistent results. Despite the methodological differences, all approaches identified offshore circalittoral mud and offshore circalittoral mixed sediments as the most affected habitats. The Gulf of Cádiz had more overall impacts than northern Spain. Impacts decreased significantly across all benthic habitats in association with declining trawling intensity, although extensive areas remained at risk. Our approach provides a scalable and robust way to assess seabed condition at broad spatial scales. By establishing critical benchmarks for habitat quality and pressure, it offers a scientifically sound tool to inform national and regional marine management strategies.

Drawing on an extended theory of planned behavior (TPB), we modeled frame-specific claim agreement, attitudes, subjective norms, perceived behavioral control, and perceived self-efficacy with structural equation models. Conservation and legality messages significantly reduced purchase intention relative to a no-message control (mean declines of 0.37-0.84 points on a 5-point scale across treatment arms) primarily through indirect psychological pathways. Conservation messages heightened harm-based evaluations and moral concern, whereas legality messages strengthened illegality appraisals and deterrence-related cognitions. Across models, claim agreement was a key proximal antecedent, subjective norms consistently predicted lower self-efficacy, and self-efficacy emerged as the most proximal positive predictor of intention. Perceived behavioral control showed no direct effect. Species-specific differences in pathways, suggestive of reactance in the big-headed turtle conservation model, reflected variation in legal signals and market narratives.

This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey availability, human disturbance, and predation by invasive non-native species. Using site monitoring data acquired from 2000 to 2023, we investigated drivers of species presence and abundance for 15 seabird species (nine Laridae, three Sulidae, two Fregatidae, and one Procellariidae) on 100 coral reef islands around New Caledonia, South Pacific. We established presence and abundance estimates using a compendium of 2805 observations and tested the relative influence of onsite breeding habitat area, characteristics of neighboring marine environments, human visitation, and rodent presence. Responses to ecological drivers varied across species and highlighted distinct functional and taxonomic groups. The presence and abundance of pelagic-feeding species with high site fidelity were predominantly determined by the availability of breeding habitat, whereas the presence of coastal foragers, including most gulls and terns, appeared constrained by resource availability near breeding sites. Human disturbance had a significant negative influence on the presence of brown noddy (Anous stolidus; [-3.41; -1.20]), masked (Sula dactylatra; [-3.85; -1.21]), and brown (Sula leucogaster; [-4.57; -1.46]) and red-footed booby (Sula sula; [-9.58; -1.20]) and a significant positive influence on the abundance of the commensal silver gull (Larus novaehollandiae; [0.03; 0.09]). Our results emphasize the importance of habitat restoration and mitigation of human disturbance for preserving breeding sites of pelagic-feeding species. However, it may be difficult to sustain populations of coastal seabirds whose presence is mostly driven by small-scale prey distribution.
