Using stable isotopes in hummingbird breath to estimate reliance on supplemental feeders

open access: yesEcology and Evolution, 2023
Understanding the ecological consequences of supplemental feeding to both hummingbirds and the plants they pollinate is complicated by logistical challenges associated with assessing relative dietary resource use with commonly applied observational ...

A multi-taxonomic survey to determine the conservation status of native pollinators

open access: yesFrontiers in Ecology and Evolution, 2023
The worldwide decline of insects calls for understanding the conservation status of key insect groups at local and regional scales. Pollinators are widely recognized as especially important to native ecosystems and agriculture and their declines have ...

GbSER02 Interacts With GhVOZ1 to Promote Fiber Elongation by Modulating Gibberellin Synthesis in Cotton

open access: yesAdvanced Science, EarlyView.
GbSER02 with a single base change (SNP517G) encodes normal serpin protein and interacts with transcription factor VOZ1 to alleviate the repression of VOZ1 on GA3ox1 and promote GA3 biosynthesis. Further, GA3 induces the expression of cell wall loosening‐related genes and decreases flavonoid content, ultimately facilitating fiber cell elongation in ...

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

open access: yesJournal 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.

Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]

open access: yes, 2015
Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...

Solar park management and design to boost bumble bee populations

open access: yesEnvironmental Research Letters, 2022
Solar photovoltaics is projected to become the dominant renewable, with much capacity being installed as ground-mounted solar parks. Land use change for solar can affect ecosystems across spatial scales and solar parks offer a unique opportunity for ...

The Pollination of the Olive [PDF]

open access: yesNature, 1908
As Knuth's great work on flower pollination, compiled from all available sources, says nothing whatever about the olive, I recently asked Prof. J. E. Coit, of Arizona, to look out for insects upon the flowers. He carefully examined many olive trees in flower at Tucson, and did not find a single insect at the flowers, with the exception of a thrips ...

Antagonistic Ghd7‐OsNAC42 Complexes Modulate Carbon and Nitrogen Metabolism to Achieves Superior Quality and High Yield in Rice

open access: yesAdvanced Science, EarlyView.
The complex centered on Ghd7 binds to numerous carbon and nitrogen metabolism genes on the genome through the corresponding motifs and transactivates the transcriptional expression of these carbon and nitrogen metabolism genes. With the assistance of OsNAC42 and other unknown Ghd7‐interacting proteins, this complex can regulate different metabolic ...

The Insecticide Imidacloprid Decreases Nannotrigona Stingless Bee Survival and Food Consumption and Modulates the Expression of Detoxification and Immune-Related Genes

open access: yesInsects, 2022
Stingless bees are ecologically and economically important species in the tropics and subtropics, but there has been little research on the characterization of detoxification systems and immune responses within them.
