Taxonomic and functional diversity of urban bees of the world

open access: yesConservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Development of a functional approach in a grassland vegetation sub-model = Desenvolvimento de uma abordagem funcional em um submodelo vegetal campestre

open access: yesActa Scientiarum: Animal Sciences, 2008
To improve our understanding of grassland dynamics under different levels of utilization, a functional description of the vegetation was introduced in a deterministic model. The selected traits and their parameterization were based on the results of a longtermexperiment in which temperate grasslands were managed for 12 years with three levels of ...

Using the capabilities approach to achieve people‐centered conservation

open access: yesConservation Biology, EarlyView.
Abstract Top‐down interventions carried out by state and nonstate institutions to conserve biodiversity and improve the lives of forest‐proximate people (FPP) in the Global South tend to reflect economistic understandings of human well‐being. More progressive and people‐centered conservation projects are guided by normative visions of how the world ...

Forest edges buffer effects of agricultural management on bee–plant interaction networks

open access: yesEcological Entomology, EarlyView.
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...

Social bees can enhance the persistence of plant–bee interactions during seasonal changes in seasonally dry tropical forests

open access: yesEcological Entomology, EarlyView.
Social bees, especially Meliponini, formed a persistent core that maintained plant–bee interactions across both dry and green seasons in the Caatinga. Persistence was not linked to broader diets; social bees used fewer plant species, despite availability, indicating selective tracking of temporally concentrated floral resources.

Does Survey Angling CPUE Reflect Population Density of Northern Pike (Esox lucius) in Small Boreal Lakes?

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Knowing the relationship between catch per unit effort (CPUE) and population density is crucial for the management of recreational fisheries. We conducted standardized angling for pike in 16 lakes (3.4–22.1 ha) to test whether lure type, color, and pike density affect CPUE and the size of captured fish.

Incorporating light pollution into projections of the future distribution of Aspisoma sticticum Gemminger, 1870 under climate change in South America

open access: yesInsect Conservation and Diversity, EarlyView.
Climate‐only models predict severe habitat contractions by 2100, especially in the Amazon, Cerrado and Caatinga, while southern and coastal Atlantic Forest areas remain refugial. Including artificial light at night increased projected stability and apparent suitability gains, especially in central and eastern South America.
