Data from: Landscape diversity and local temperature, but not climate, affect arthropod predation among habitat types
<p>Arthropod predators are relevant for top-down regulation of insect herbivores. Biotic and abiotic factors influence predator communities and their activity with consequences for the strength of top-down regulation ('arthropod predation'). Anthropogenic climate and land-use change urges a deeper understanding of the combined effects of potential drivers on arthropod predation. This study obtained arthropod predation rates on 113 plots of open herbaceous vegetation adjacent to different habitat types (forest, grassland, arable field, settlement) along climate and land-use gradients in Bavaria, Germany, using a standardized method of artificial caterpillars at ground level. Predation rates were analysed with regard to habitat characteristics (habitat type, plant species richness, local mean temperature and mean relative humidity during artificial caterpillar exposure), landscape diversity (0.5–3.0-km, six scales), climate (multi-annual mean temperature, 'MAT') and interactive effects of habitat type with other drivers. Arthropod predation rates did not substantially differ between the studied habitat types, related to plant species richness and across the Bavarian-wide climatic temperature gradient, and also no interactive effects were observed. However, arthropod predation rates were limited by low local mean temperatures, tended to decrease towards higher relative humidity and increased towards more diverse landscapes at a 2-km scale. Thus, high arthropod predation rates in open herbaceous vegetation are favoured by diverse landscapes independent of the dominant habitat in the vicinity. Diversifying landscapes may help to improve top-down control of herbivores, e.g. agricultural pests, but more research is needed to derive specific recommendations on landscape management. Little influence of MAT on predation rates suggests that moderate increases of MAT may not strongly alter this process in the near future.</p>
Functional traits and metacommunity theory reveal that habitat filtering and competition maintain bird diversity in a human shared landscape
<p>Human shared landscapes cover much of Earth, yet their conservation value is contested. This controversy may persist because previous studies have examined species diversity, rather than the processes through which such diversity is maintained. For example, a site exhibiting high diversity may not actually bolster populations if the diversity is only maintained through net immigration. Recent research has begun to isolate the processes that maintain metacommunities and develop functional trait methods to identify these processes. However, the processes underlying bird communities remain obscure. Here, we leverage metacommunity theory, functional trait partitioning, and a Bayesian multispecies abundance model to assess whether a shared landscape – woody perennial polyculture farms – bolsters bird diversity. Such farms grow multiple species of food-producing woody perennials together with vegetative groundcover. We surveyed birds and their <em> in situ </em> functional traits across the US Midwest in traditional agriculture, woody perennial polyculture, prairie, and woods. We found that woody perennial polycultures exhibited the highest bird diversity and were the most preferred by many species (including threatened ones). Moreover, our functional trait analysis suggests that this diversity is maintained through habitat filtering and competition, rather than merely immigration. Thus, shared landscapes can likely conserve birds by providing a distinct habitat. These results suggest that woody perennial polyculture farms offer substantial potential to support bird populations in the US Midwest. Our study demonstrates the utility of <em> in situ </em> functional trait partitioning within a Bayesian framework to unmask ecological processes and help assess the conservation value of landscapes.</p>
