Abstract Context Land use changes have become a major driver of biodiversity loss, impacting natural ecosystems and the species that depend on them. As result, many isolated from their habitats cannot interact with other as they would in ecosystems. Ecological interactions are crucial for functioning stability Objectives Here, we aimed to evaluate effects landscape structure enemy community antagonistic networks consisting enemies solitary trap-nesting bees wasps, at two scales.

While describe host-natural network used robustness metric, enemy’s niche overlap, linkage density. Results The is richer when there high connectivity local scale, while heterogeneity increases abundance, diversity, rate. High similarity between species’ trophic niches occurs antagonist dominated by generalist enemies. Conclusions Our study presents one first results about functional communities interactions, highlighting importance its conservation not just insects respond only presence hosts region. specialist networks, both bee wasp hosts, may occur through increased patches landscapes restored fragments.

Abstract Vertebrate species worldwide are currently facing significant declines in many populations. Although we have gained substantial knowledge about the direct threats that affect individual species, these only represent a fraction of broader vertebrate threat profile, which is also shaped by interactions. For example, faced prey can jeopardize survival their predators due to food resource scarcity. Yet, indirect arising from interactions received limited investigation thus far. In this study, investigate consequences anthropogenic on biodiversity context European webs. We integrated data trophic among over 800 terrestrial vertebrates, along with associated human‐induced threats. quantified and mapped vulnerability various components web, including interactions, groups six major threats: pollution, agricultural intensification, climate change, exploitation, urbanization, invasive alien diseases. Direct exploitation intensification were two for webs: affecting 34% 31% respectively, they threaten 85% 69% Europe. By integrating network ecology impact assessments, our study contributes better understanding magnitude impacts biodiversity.

In response to ongoing coastal urbanization, it is critical develop effective methods improve the biodiversity and ecological sustainability of artificial shorelines. Enhancing topographic complexity infrastructure through mimicry natural substrata may facilitate establishment ecosystem engineering species associated biogenic habitat formation. However, interactions between engineers their substratum are likely determined by organismal size resource needs, thus making responses topography highly scale-dependent. Here, we assessed properties (rugosity, surface area, micro-surface orientations) that underpin abundance distribution two (fucoids, limpets) across six spatial scales (1–500 mm). Furthermore, 'biogenic' rugosity created barnacle matrices fine (1–20 Field surveys 3D scanning, conducted substrata, showed major effects variables on engineer assemblages occupancy, while additional abiotic environmental factors (compass direction, wave exposure) biotic associations only had weak influences. Natural exhibited ≤67 % higher than ones. Fucoid-covered patches were predominantly with high-rugosity horizontal micro-surfaces, homescars limpets (≥15 mm shell length) predominated smoother patches. Barnacle-driven homogenized at ≤10 mm. Our findings suggest scale-dependent a key driver fucoid formation limpet use, wider eco-engineering applications for mimicking ecologically impactful infrastructure.

Abstract Through the end of century, biodiversity is expected to markedly decline around world due climate change, habitat loss, and other factors. Because this, there an increasing need for more efficient, effective, collaborative conservation efforts worldwide. While many global national threat assessment databases exist, they may only have limited utility at regional local scales where on-the-ground best implemented. To better identify species risk a scale, 14 state fish wildlife agencies in northeastern United States worked with taxonomic experts across Northeast create most recent (2023) list Regional Species Greatest Conservation Need (RSGCN).

Abstract Ecosystems typically exhibit resilience to disturbances, yet excessive pressure can disrupt species interactions, resulting in biodiversity loss. Conservation interventions strive safeguard ecosystems and reinstate vital ecological functions. Competition between animals plays a pivotal role ecosystem persistence dynamics, but its significance is often underestimated conservation research. We conducted global review that analyzed 147 articles, focusing on the impact of competitive interactions interventions. found tendency for researchers retrospectively interpret observed patterns as competitive. Negative outcomes, such declines, were frequently associated with interactions. Despite efforts predict outcomes using characteristics competition process, we no consistent based these characteristics. Our findings underscore considerable influence may have emphasizing need proactive consideration dynamics part planning By integrating animal into planning, monitoring, mitigation efforts, unexpected negative impacts be minimized, fostering more effective outcomes.

Abstract There is an increasing disconnect between people and nature as we become more urbanised. Intensification in cities often results a reduction of natural areas, homogenised manicured green spaces, loss biota. Compared to rural urban dwellers are less likely visit areas recognise value Reconnecting with the city not only benefits human mental physical wellbeing but can also have positive effects on how biodiversity act conservation issues. However, some contexts, push reconnect may unintended negative outcomes biodiversity, particularly if place-specific used greening. In current crisis, using vegetation space design that reflective environmental context further residents, Indigenous people, from their local environment species, entrench extinction experience values. This result residents applying wildlife gardening practices, such bird feeding, specific place, benefit introduced species over indigenous species. Furthermore, gateways for invasive greening projects locally sourced has already left surrounding regions large weed legacy. Using be resource intensive, highly beneficial give unique sense place. Rather than simply adding ‘more nature’ cities, messaging should complex, emphasising need avoid impacts ecological cultural services.

Abstract Landscape structure plays a key role in mediating variety of ecological processes affecting biodiversity patterns; however, its precise effects and the mechanisms underpinning them remain unclear. While landscape have been extensively investigated both empirically theoretically from metapopulation perspective, spatial at scale poorly explored metacommunity perspective. Here, we attempt to address this gap using spatially explicit, individual‐based model explore compositional heterogeneity per se configuration on diversity patch levels via their influence long‐term community assembly processes. Our simulates communities composed species annual, asexual organisms living, reproducing, dispersing, competing within grid‐based, fractal landscapes that vary magnitude environmental degree autocorrelation. Communities are additionally subject temporal fluctuations external immigration, allowing for turnover composition. We found autocorrelation had differing richness, diversity, scales. Landscape‐level was driven by dissimilarity level increased with greater heterogeneity, while richness largely result short‐term accumulation immigrants decreased heterogeneity. Both variance indicating reduction over time. Patch‐level patterns appeared be overall local mass effects, resulting maximum patch‐level moderate high
