Investigação em apicultura em Portugal: Portugal, apicultura e Nosema [PDF]

, 2012
A Nosemose é uma doença das abelhas melíferas (Apis mellijera L.), cujo agente etiológico tradicional, (o microsporídio unicelular Nosema apis Zander), foi identificado há cerca de cem anos (Paxton, 2010). Considerada uma das patologias mais predominante e prejudicial para as abelhas ocidentais, tem sido intensamente estudada (apesar de nem sempre ser ...

Superinfection Exclusion in Neotropical Honey Bees May Block DWV-B, an Emerging Infectious Disease Variant of Deformed Wing Virus. [PDF]

Evol Appl
ABSTRACT RNA viruses often comprise multiple variants that co‐circulate in a host population, with potentially complex dynamics. Deformed wing virus (DWV), arguably the most impactful virus of honey bees (Apis mellifera), nowadays exists as two major variants, genotypes A (DWV‐A) and B (DWV‐B), which provide an amenable window into the dynamics of ...

Proximity to Natural Habitat Is Not Consistently Associated With Pollination Services in Tropical Smallholder Farms: A Systematic Review and Meta-Analysis. [PDF]

Ecol Lett
We conducted a systematic review and meta‐analysis of 35 studies to examine the relationship between distance to natural habitat and pollinator abundance, species richness and crop fruit set in tropical smallholder farms. We found no consistent effects on abundance or fruit set, and only a slight, highly variable negative effect on pollinator richness,

Dominance of African racial ancestry in honey bee colonies of Mexico 30 years after the migration of hybrids from South America. [PDF]

Evol Appl
Abstract The Africanized honey bee, a hybrid of Apis mellifera scutellata from Africa with European subspecies, has been considered an invasive species and a problem for beekeeping. Africanized bees arrived in Mexico in 1986, 30 years after their accidental release in Brazil.

Spatial mismatch between wild bee diversity hotspots and protected areas

Conservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract Wild bees are critical for multiple ecosystem functions but are currently threatened. Understanding the determinants of the spatial distribution of wild bee diversity is a major research gap for their conservation. We modeled wild bee α and β taxonomic and functional diversity in Switzerland to uncover countrywide diversity patterns and ...

Facilitating biodiversity conservation through partnerships to achieve transformative outcomes

Conservation Biology, Volume 37, Issue 3, June 2023., 2023
Abstract Conservation biology is a mission‐driven discipline that must navigate a new relationship between conservation and science. Because conservation is a social and political as well as an ecological project, conservation biologists must practice interdisciplinarity and collaboration.

Antimicrobial, Antioxidant, Anti-Inflammatory, and Cytotoxic Activities of Propolis from the Stingless Bee Tetragonisca fiebrigi (Jataí). [PDF]

Evid Based Complement Alternat Med, 2015
Propolis from stingless bees Tetragonisca fiebrigi found in Brazil is used in folk medicine by their nutritional and therapeutic properties. However, there are no scientific records evidencing such properties. The present study was designed to investigate the chemical composition and the biological properties of propolis from T. fiebrigi. For this, the
