Global Trends in the Status of Bird and Mammal Pollinators [PDF]

, 2015
Biodiversity is declining, with direct and indirect effects on ecosystem func-tions and services that are poorly quantified. Here, we develop the first globalassessment of trends in pollinators, focusing on pollinating birds and mam-mals.

Potential landscape-scale pollinator networks across Great Britain: structure, stability and influence of agricultural land cover [PDF]

, 2018
Understanding spatial variation in the structure and stability of plant-pollinator networks, and their relationship with anthropogenic drivers, is key to maintaining pollination services and mitigating declines.

Enhancement of developmental defects in the boron‐deficient maize mutant tassel‐less1 by reduced auxin levels

Journal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Plant responses to deficiencies of the micronutrient boron are diverse and go beyond the well‐characterized function of boron in cell wall crosslinking. To explain these phenotypic discrepancies, hypotheses about interactions of boron with various phytohormones have been proposed, particularly auxin.

Urban bee functional groups response to landscape context in the Southeastern US

Frontiers in Sustainable Cities, 2023
We investigated the influence of landscape cover on urban bee community functional groups. We observed a diversity of functional groups across primarily forested and primarily urban sites, however particular species were favored by forest/urban spaces ...
