Genome‐Wide Association Studies Reveal the Genetic Architecture of Ionomic Variation in Grains of Tartary Buckwheat

Advanced Science, EarlyView.
In this study, variation and genetic basis of ionome among Tartary buckwheat population are investigated, illuminating their significance in the domestication and diversification of Tartary buckwheat. And three genes (FtACA13 for Na content, FtYPQ1 for Zn content, FtNHX2 for As content) are identified with the dominant haplotypes and functional ...

Self-fertility studies of some sweet cherry (Prunus avium L.) cultivars and selections

International Journal of Horticultural Science, 2004
Fruit set of two sweet cherry cultivars (Alex' and 'Stella' ) and four Hungarian selections have been studied over two years following open pollination, unassisted self-pollination (autogamy) and artificial self-pollination (geitonogamy).

Post‐pollination barriers contribute to coexistence of partially pollinator‐sharing Arisaema species (Araceae)

Ecology and Evolution, 2023
Reproductive isolation plays an important role in maintaining the species integrity of sympatric close relatives. For sympatric Arisaema species, interspecific gene flow is expected to be effectively prevented by pre‐pollination barriers, particularly ...

Pollinator conservation—the difference between managing for pollination services and preserving pollinator diversity

Current Opinion in Insect Science, 2015
Our review looks at pollinator conservation and highlights the differences in approach between managing for pollination services and preserving pollinator diversity. We argue that ecosystem service management does not equal biodiversity conservation, and that maintaining species diversity is crucial in providing ecosystem resilience in the face of ...

Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

Advanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Where the Bee Sucks -- A Dynamic Bayesian Network Approach to Decision Support for Pollinator Abundance Strategies [PDF]

arXiv, 2022
For policymakers wishing to make evidence-based decisions, one of the challenges is how to combine the relevant information and evidence in a coherent and defensible manner in order to formulate and evaluate candidate policies. Policymakers often need to rely on experts with disparate fields of expertise when making policy choices in complex, multi ...

Assessing flower‐visiting arthropod diversity in apple orchards through metabarcoding of environmental DNA from flowers and visual census

Environmental DNA, Volume 5, Issue 1, Page 117-131, January 2023., 2023
The diversity of flower‐visiting arthropods in four Danish apple orchards was assessed using molecular (metabarcoding) and non‐molecular techniques. The aim was to obtain a broader overview of arhtropod communities present to support future management practices towards more sustainable agricultural systems.

A horizon scan of future threats and opportunities for pollinators and pollination [PDF]

PeerJ, 2016
Background. Pollinators, which provide the agriculturally and ecologically essential service of pollination, are under threat at a global scale. Habitat loss and homogenisation, pesticides, parasites and pathogens, invasive species, and climate change have been identified as past and current threats to pollinators.

The Pollination of the Olive [PDF]

Nature, 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 ...

Impacts of geopolitics and policy on Latin American biodiversity and water resources

Agribusiness, EarlyView.
Abstract Latin America is a major agricultural producer with important natural resources. Efforts have been made to protect sensitive areas but are hindered by agricultural trade disruptions outside the control of individual countries due to globally integrated crop markets.
