Ancient hybridization and phylogenetic discordance: Exploring evolutionary complexity in Asteraceae
Applications in Plant Sciences, EarlyView.Abstract Premise Conflicting phylogenetic signals are common in plant phylogenomics and often reflect evolutionary histories shaped by processes like hybridization, incomplete lineage sorting, and whole‐genome duplication (WGD). We aimed to identify and assess these complex processes in the hyper‐diverse family Asteraceae to offer insight into the ...

AN EMPIRICAL ANALYSIS OF HONEYBEE POLLINATION MARKETS
Pollination by honeybees plays an important role in modern agriculture. Some crops are greatly dependent on honeybees (almonds, apples, avocados, blueberries, and cherries are examples) while the yields and quality of other crops are significantly ...

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

An Economic Valuation of Pollination Services in Georgia
The production of many crops depends on biotic pollination. As pollinator populations decline, assessments of the potential consequential loss of economic value are critical.

The Anatomical Record, EarlyView.Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Evidence of widespread pollen limitation in diverse specialty crops on commercial farms
Royal Society Open ScienceSpecialty crops (non-staple fruits and vegetables) have diverse pollination requirements and pollinator communities, yet production may be limited by pollen limitation.

The Effect of Flower Development and Pollination on the Fruit Set of Kalanchoe
, 2014 鵝鑾鼻燈籠草及其變種花朵開放後4天，花柱明顯的伸長並與花藥相互接觸。長壽花'Isabella'於開花當天，花柱已與花冠內下層的花藥相接觸，於花朵開放後1天，花柱已伸出花藥之外。三種親本以人工雜交、人工自交、自交(套袋使其授粉)、開放授粉或除雄後套網處理，結果以人工自交以或開放授粉能得到最多種子，其次為人工雜交授粉，自花授粉處理種子數較少，而以除雄後再套網處理者則未收得任何種子。使用鵝變鼻燈籠草為母本與長壽花'Isabella'雜交時，每朔果中平均收得135顆種子，反交時每朔果中平均收得33粒種子。The
