The Path to Sustainability: Apricot Growers' Willingness to Adopt Agroecological Practises in Malatya, Türkiye

open access: yesSustainable Development, EarlyView.
ABSTRACT The global food system faces sustainability, safety, and equity challenges. Agroecological practises offer solutions through sustainable production and resource conservation. This study examines apricot producers' willingness to adopt agricultural practises in Malatya, Türkiye, focusing on their attitudes, behaviours and the factors ...

Bumblebee Abundance in Species-Rich Grasslands in Southern Sweden Decreases with Increasing Amount of Arable Land at a Landscape Level

open access: yesInsects
Conservation of bumblebee populations is essential because of their role as pollinators. Declines in bumblebee abundance have been documented in recent decades, mostly attributed to agricultural intensification, landscape simplification and loss of semi ...

Diversity and Trophic Relationships of Functional Groups of Bumblebees (Hymenoptera: Apidae, Bombus Latreille, 1802) in Urban Habitats

open access: yesPsyche: A Journal of Entomology, 2020
Species composition, distribution, and trophic relationships of bumblebees are studied in six types of urban habitat: urban parks, botanical gardens, least-disturbed areas within the city, residential areas, and roadsides.

The genomes of two key bumblebee species with primitive eusocial organization [PDF]

open access: yes, 2015
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies.

Development of optimized methods for unbiased dusky grouse population monitoring using real and simulated data

open access: yesWildlife Biology, EarlyView.
Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.

The Role of Pathogens in Bumblebee Decline: A Review

open access: yesPathogens
Bumblebees, the most important wild pollinators in both agricultural and natural ecosystems, are declining worldwide. The global decline of bumblebees may threaten biodiversity, pollination services, and, ultimately, agricultural productivity.

Flower angle favors pollen export efficiency in the snowdrop Galanthus nivalis (Linnaeus, 1753) but not in the lesser celandine Ficaria verna (Huds, 1762)

open access: yesPlant Signaling & Behavior, 2023
Flower angle is crucially important for accurate pollination and flower protection against abiotic factors. Evolutionary factors shaping floral traits are particularly strong for bilaterally symmetric flowers because these flowers require more ...

Emergent electrodynamics from the Nambu model for spontaneous Lorentz symmetry breaking [PDF]

open access: yes, 2012
After imposing the Gauss law constraint as an initial condition upon the Hilbert space of the Nambu model, in all its generic realizations, we recover QED in the corresponding non-linear gauge A_{\mu}A^{\mu}=n^{2}M^{2}.

Does "Flight of the Bumblebee" resemble bumblebee flight?

open access: yes, 2022
"Flight of the Bumblebee" is one of the rare pieces of classical music which, through its association with bees, has cemented its place in pop culture. However, it is unclear whether its composer, Nikolai Rimsky-Korsakov, actually took inspiration from bumblebee flight patterns.
