Plight of the bumblebee [PDF]

open access: yesCurrent Biology, 2003
AbstractOne group of insects highlight some of the potential economic damage that loss of biodiversity may entail for the future of human food crops. Nigel Williams reports.

Spontaneous Lorentz and Diffeomorphism Violation, Massive Modes, and Gravity [PDF]

open access: yes, 2008
Theories with spontaneous local Lorentz and diffeomorphism violation contain massless Nambu-Goldstone modes, which arise as field excitations in the minimum of the symmetry-breaking potential.

Warm Temperatures Reduce Flower Attractiveness and Bumblebee Foraging

open access: yesInsects, 2021
Simple Summary In the context of climate warming, modifications in plant pollination and reproductive success constitute a crucial issue. Modifications of both floral signals (display, size of flowers) and rewards (nectar and pollen) due to increased air

Insects Associated with Michigan Bumblebees (\u3ci\u3eBombus\u3c/i\u3e Spp.) [PDF]

open access: yes, 2017
(excerpt) Studies of insect associates of bumblebees are not new. For example, Tuck (1896, 1897) reported over 50 species of insects associated with nests of British bumblebees. Sladen (1912) discussed nest associates and parasites of European bumblebees,

Spatial Relation of Bumblebees (Hymenoptera-Apidae) with Host-Plant and their Conservation Issues: An Outlook from Urban Ecosystem of Kathmandu Valley, Nepal [PDF]

open access: yes, 2019
Ecology and conservation status of bumblebee species remains poorly understood, especially in rapidly degrading urban ecosystems, which is important considering the role of bumblebees in the pollinations. We collected more than 200 bumblebee (Bombus

Strain-level analysis reveals the vertical microbial transmission during the life cycle of bumblebee

open access: yesMicrobiome, 2021
Microbial acquisition and development of the gut microbiota impact the establishment of a healthy host-microbes symbiosis. Compared with other animals, the eusocial bumblebees and honeybees possess a simple, recurring, and similar set of gut microbiota ...

Bumblebee gravity with a Kerr–Sen like solution and its Shadow [PDF]

open access: yesThe European Physical Journal C, 2020
We have considered the bumblebee gravity model where lorentz-violating (LV) scenario gets involved through a bumblebee field vector field Bμ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb}

Einstein–Bumblebee-dilaton black hole solution

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We obtain new black hole solutions in a Einstein–Bumblebee-scalar theory. By starting with a Einstein–Bumblebee theory in ( $$D+d$$ D + d ) dimensions, the scalar dilaton field and its interaction with the gravitational and Bumblebee fields are obtained ...

Monitoring bee health in European agro-ecosystems using wing morphology and fat bodies [PDF]

open access: yesOne Ecosystem, 2021
Current global change substantially threatens pollinators, which directly impacts the pollination services underpinning the stability, structure and functioning of ecosystems.

The role of automated feedback in training and retaining biological recorders for citizen science [PDF]

open access: yes, 2016
The rapid rise of citizen science, with lay people forming often extensive biodiversity sensor networks, is seen as a solution to the mismatch between data demand and supply while simultaneously engaging citizens with environmental topics.
