Summary: Increasing patch richness may support a greater number of bee taxa, but individual bee taxa vary considerably in their response to components of landscape complexity. The total abundance of wild bees and its response to contagion also show temporal variability, with the amount of cropland positively associated with abundance earlier in the season and negatively later in the growing season.

Summary: The study revealed that urban cover and garden size are positively associated with bee species richness and abundance. Urban cover is also related to the prevalence of specific bee traits, suggesting that urbanization selects for species with certain characteristics.

Summary: The study reveals that the form of functional response for foragers can vary depending on the temporal and spatial scales, requiring a hierarchy of functional responses to represent consumption rates. Different scales may require prey-centered or patch-centered functional responses to describe prey consumption rates accurately. The landscape pattern changes through time may also influence the functional response at a colony level over longer time scales.

Summary: This article examines the relationship between forest landscape restoration (FLR) and landscape ecology, identifying areas of convergence such as landscape, integration, and connectivity, as well as areas of divergence including process versus analysis, transformative nature, and political nature of FLR. Suggestions for integration between the two disciplines are proposed for future research and practice.

Summary: Species' cognitive traits are influenced by their ecology, with individuals in different roles within a species exhibiting varying cognitive capabilities. Through experiments with wild bees, it was found that queens performed better than workers in certain learning tasks, indicating a potential link between cognitive abilities and ecological requirements for different roles within a colony.

Summary: Agricultural intensification may lead to declines in bumble bee species, while high crop diversity is beneficial for insect conservation. Increasing on-farm and landscape-level crop diversity is predicted to have positive effects on bumble bees, even in agriculturally dominated areas.

Summary: The study found that colonies with more larger workers had positive effects on worker production under low or fluctuating resource environments, while colonies with more smaller workers had negative effects. This research demonstrates the potential application of functional linear models in exploring high-dimensional ecological systems, such as the contributions of individuals with different traits to colony dynamics.

Summary: This study assessed the impact of surrounding habitat on monarch presence and reproduction in specific habitat patches, finding that optimal sites for monarch habitat restoration are within landscapes with little habitat. High milkweed density and floral richness and abundance should be conservation goals in these landscapes.

Summary: This paper presents landscape design models that can enhance the symbiotic associations between farming production and beekeeping in Greece. By analyzing four agricultural farms, the study found that the design models, which involve planting enrichment and integration of natural patches, can increase crop yields when beehives are installed. Therefore, landscape design models are important for improving agricultural production and protecting biodiversity.

Summary: The changes in a host's microbiome over its lifespan can affect its development and aging. In this study, the temporal dynamics and stability of the bumble bee worker gut microbiome were characterized. It was found that microbiome assembly is highly predictable at the community level, similar to patterns observed in the human gut. However, at the strain level, there were stochastic colonization events. Differences in temporal dynamics among symbiont species were also observed. The gut microbiome and host transcriptome were found to stabilize, rather than senesce, with age. These findings provide a foundation for further exploring the mechanisms and functional outcomes of bee microbiome succession.

Summary: Southern Poland is home to diverse bumblebee habitats, with over 25 species identified in the Malopolska Upland. However, bumblebee populations have declined significantly in recent years, likely due to habitat fragmentation. Understanding the impact of habitat fragmentation is crucial for the conservation of bumblebee species.

Summary: Land use intensification affects wildlife movements, especially specialist carnivores. Our study investigates the influence of agricultural practices and landscape configuration on the spatial behavior of wildcats in Europe. We found that wildcat home range size increases with high impact agriculture proportion and forest integrity, but decreases with forest edge density. Forest edge density buffers the detrimental effects of high impact agriculture. To conserve wildcats in Europe, it is important to protect sustainable mosaic-structured landscapes.

Summary: In this study, the infection of V. bombi among Japanese bumblebees and the alien species, Bombus terrestris, was investigated using PCR and microscopy. It was found that V. bombi infected the subgenus Bombus s. str. species/subspecies with a low prevalence, suggesting it may be native to Japan. A new microsporidian parasite was also discovered, which infected the subgenus Diversobombus species/subspecies with a high prevalence.

Summary: The study introduces an automated pollen analysis method based on deep learning convolutional neural networks, which improves the efficiency and reliability of pollen analysis. It shows that merging a large number of species into a small number of pollen types can increase the accuracy of the model. Validation experiments demonstrate that this automated method can analyze large quantities of real pollen data with reasonable accuracy, providing widely accessible and shareable pollen analysis resources.

Summary: In southernmost Sweden, the relative abundance of Bombus terrestris has increased significantly over the past 150 years, largely due to rising temperatures. The activity period of males has also advanced by 41 days, indicating better adaptation of Bombus terrestris to contemporary conditions.

Summary: The introduction of nonnative plants may negatively impact native invertebrate fauna, with nonnative trees in urban environments hosting significantly fewer invertebrates compared to native trees. The effect of tree species origin on urban invertebrate abundance was greater than the effect of urbanization.

Summary: This study examines the gap between data availability and implementation of BGI in urban planning authorities in Sweden, identifying challenges related to data availability, data management, and GIS knowledge. Improvements in data management organization and trans-disciplinary cooperation are necessary to understand and interpret different types of data for efficient planning of BGI. Developing pan-municipal data management systems to bridge sectors and disciplines is essential to ensure efficient management of the urban environment.

Summary: Urbanisation can lead to declines in insect pollinators, but urban green spaces in densely populated areas can benefit a range of pollinators. The abundance of bee species was influenced by vegetation cover and human population density, with different effects on non-eusocial and eusocial species. Hoverflies were negatively affected by human density but positively influenced by vegetation cover, supporting the idea that urban greening can benefit insect pollinators.

Summary: Green infrastructure is used in policymaking to promote biodiversity and enhance ecosystem services. The Swedish GI policy assemblage consists of policy ideas developed in Sweden and the EU, but its implementation may promote less disruptive GI measures, making its capacity to halt biodiversity loss marginal.
