Impact of Bee Species and Plant Density on Alfalfa Pollination and Potential for Gene Flow

Psyche: A Journal of Entomology, 2010
In outcrossing crops like alfalfa, various bee species can contribute to pollination and gene flow in seed production fields. With the increasing use of transgenic crops, it becomes important to determine the role of these distinct pollinators on alfalfa

Sublethal neonicotinoid insecticide exposure reduces solitary bee reproductive success

, 2014
1.Pollinating insects provide crucial and economically important ecosystem services to crops and wild plants, but pollinators, particularly bees, are globally declining as a result of various driving factors, including the prevalent use of pesticides for

Conservation of solitary bees in power-line clearings: Sustained increase in habitat quality through woody debris removal

Global Ecology and Conservation, 2020
Declining populations of wild pollinators have increased the interest in the management of human-modified landscapes for pollinator conservation. Modified landscape features, such as power-line clearings, may provide valuable habitats with increased ...

Foraging ranges of solitary bees

Journal of Animal Ecology, 2002
Summary Habitat requirements of solitary bees include nesting sites, food resources and nesting material. We used translocation experiments to establish foraging distances and measured foraging trip duration to analyse how solitary bees cope with the distance between nesting sites and suitable food plants in different habitat types.

Wild solitary bees and their use of bee hotels in southwest Spain

Journal of Apicultural Research, 2021
There is an increasing interest in preserving and, if possible, increasing wild bee populations as evidenced by increasinginvestigations into providing supplemental nesting resources, commonly called bee hotels. The study presented herewas carried out in 2017 and 2018 with two objectives: a) to understand the role that insect refuges could have ...

Mitigating the Effects of Habitat Loss on Solitary Bees in Agricultural Ecosystems

Agriculture, 2020
Solitary bees and other wild pollinators provide an important ecosystem service which can benefit both the agricultural economy and the sustainability of many native ecosystems. Many solitary bees, however, are experiencing decreases in their populations

Honey bee viruses in solitary bees in South America: simultaneous detection and prevalence

, 2023
Viruses and Nosema spp. presence was investigated in solitary bees, honey bees, and in stingless bees from an apiary site and a non-apiary site in Brazil.

Desynchronizations in bee–plant interactions cause severe fitness losses in solitary bees [PDF]

Journal of Animal Ecology, 2017
Abstract Global warming can disrupt mutualistic interactions between solitary bees and plants when increasing temperature differentially changes the timing of interacting partners. One possible scenario is for insect phenology to advance more rapidly than plant phenology.

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...
