Abstract Aim The mechanisms determining the distribution of number sites species occupy, occupancy frequency (OFD), remain incompletely understood despite decades research. To explore dominant responsible for shape and temporal dynamics empirical OFD, we develop a simple patch framework with intrinsically regulated local richness fit model to highly replicated dataset describing macroinvertebrate, macrophyte diatom occupancy. Location England. Time period Up years between 1990 2020. Major taxa studied Macroinvertebrates, macrophytes diatoms. Methods We study OFD in freshwater metacommunities England across time. consider change richness, composition, OFD. Goodness‐of‐fit steady state model—which predicts log‐series OFD—to observations is assessed. Additionally, test capacity predict metacommunity‐scale processes. Results Our provides consistently good OFDs. It can additionally be used turnover. Main conclusions results support view that metacommunity structure reflects dynamic controlled by limits coexistence.

Abstract Enhancing global biodiversity is one of the key pillars UN’s Sustainable Development Goals, widely acknowledged as necessary to mitigate climate change. Nevertheless, an annual additional US$ 700 billions funding required reach ‘30 by 30’ target set out in Kunming-Montreal Global Biodiversity Framework. The proposed voluntary credit market aims bridge this gap via a market-based mechanism assigning financial value and ecosystem services. To capitalise on nascent market, several credits are emerging from independent start-ups, internationally respected NGOs, established carbon companies. Projects which primary funded sales must align their objectives with issuance methodology avoid underdelivering commitments. In pioneering study, diderences behaviour between six diderent well-established were investigated, highlight impact choice evaluate accuracy representing level changes. Our results indicate that all suitable for tracking basic restoration edorts, however there significant methodologies thus responsiveness interventions. Furthermore, not was successfully track distinct nature-positive or nature-loss experiments simulated, suggesting universal remains unattainable.

Biological invasions are complex scale-dependent processes. Metacommunity ecology provides the means to understand effects of invasive non-native species (INNS) because it explicitly considers how local and regional processes interact drive three main components bio-diversity: alpha, beta, gamma. White-popinac (Leucaena leucocephala (Lam.) de Wit) is a widely distributed INNS in regenerating forests Atlantic Forest (Brazil). results particular spatial structure as forms dense homogeneous patches, instead spreading individuals throughout invaded areas. Here we took advantage this unique configuration formed by patches native forest, areas, white-popinac investigate dynamics plant (meta-)communities under natural regeneration affected white-popinac.
