Crop and landscape heterogeneity increase biodiversity in agricultural landscapes: A global review and meta‐analysis

Ecology Letters, Год журнала: 2024, Номер 27(3)

Опубликована: Март 1, 2024

Abstract Agricultural intensification not only increases food production but also drives widespread biodiversity decline. Increasing landscape heterogeneity has been suggested to increase across habitats, while increasing crop may support within agroecosystems. These spatial effects can be partitioned into compositional (land‐cover type diversity) and configurational arrangement), measured either for the mosaic or both crops semi‐natural habitats. However, studies have reported mixed responses of in these components taxa contexts. Our meta‐analysis covering 6397 fields 122 conducted Asia, Europe, North South America reveals consistently positive heterogeneity, as well plant, invertebrate, vertebrate, pollinator predator biodiversity. Vertebrates plants benefit more from invertebrates derive similar benefits heterogeneity. Pollinators predators favour are consistent vertebrates tropical/subtropical temperate agroecosystems, annual perennial cropping systems, at small large scales. results suggest that promoting increased by diversifying current UN Decade on Ecosystem Restoration, is key restoring agricultural landscapes.

Abstract Context Birds, as indicators of biodiversity, are experiencing habitat reduction and loss due to landscape changes. Evidence is mounting that the response bird richness patterns remains controversial on a global scale. In this study, we conducted quantitative synthesis gain comprehensive understanding relationship. Our findings contribute development conservation strategies align with objectives SDG15. Objective Through review, study investigated effects analyzed sources heterogeneity in results. Methods A random-effects model was utilized merge impacts metrics richness, meta-regression analysis performed investigate origins heterogeneity. Results The review encompassed 101 articles from 51 countries worldwide. Field sampling emerged primary method for acquiring data, multiple linear regression generalized models main analytical approaches. meta-analysis results highlighted area crucial factor influencing richness. Regarding composition, proportions forests, shrublands, water bodies positively impacted while agricultural land urban had negative effects. relationship between complexity influenced by factors, including net productivity (NPP) precipitation.

Regional differences of functional and taxonomic bird diversity in tropical agroforests of Peru

Abstract Diversity and functionality of bird communities in tropical agroforests are shaped by their surrounding landscape, particularly the extent type natural forest. However, most evidence comes from rainforest landscapes, whereas bearing such trends other forest types remains understudied. We compared functional beta diversity 23 cacao embedded landscapes two contrasting Peruvian regions: seasonally‐dry forests subtropical rainforests Andean foothills. Strong climatic seasonality affects both but vegetation structure complexity differ. found higher species richness ( n = 179 spp) turnover than dry landscape 64 spp). Only distance increased dissimilarity driven loss, that is, nestedness component diversity. This points to importance conserving within broader matrix, with known benefits for pest control yield. Functional indices were not influenced either proportion insects birds' diet decreased 27% along a 1 km gradient landscape. In however, it only 3% across same gradient. Far (≥1 km), specialization ~33% 20% respectively. These differences indicate regionally‐adapted agroforest management is paramount ecosystem services as control.

Understanding biodiversity is essential for preserving the stability of river ecosystems. However, impact landscape configurations and seasonal variations on within undammed ecosystems remains unexplored. Therefore, we selected Chishui River-a naturally flowing tributary upper Yangtze River-for a survey periphytic algae. The present study focuses fluctuations in β-diversity algae River its correlation with surrounding patterns. Our findings indicate that there substantial influence community structure these ecosystem. Concurrently, observed turnover component predominantly contributes to β-diversity. In light findings, recommend conservation measures be implemented across entire basin safeguard regional biodiversity. Redundancy analysis elucidated water temperature, conductivity, pH were primary environmental drivers shaping algal communities. Furthermore, additional analyses using random forest model indicated fragmentation complexity key determinants Notably, number patches was strongly correlated It important highlight maintaining an optimal balance between their size crucial enhancing ecosystem's capacity preserve summary, our provide insights into interplay land-use practices complex riverine environments, thereby offering scientific foundation management
