Does the abiotic environment influence the distribution of flower and fruit colors?
American Journal of Botany, EarlyView.Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Microbiology SpectrumClostridioides difficile (C. difficile) is widely distributed in the intestinal tract of humans, animals, and in the environment. It is the most common cause of diarrhea associated with the use of antimicrobials in humans and among the most common ...

Revision of the Maddenia clade of Prunus (Rosaceae)
PhytoKeys, 2012 The Maddenia clade of Prunus L. is monographed based on herbarium and field studies. Four species are currently accepted in this group: Prunus himalayana J.Wen, Prunus hypoleuca (Koehne) J.Wen, Prunus hypoxantha (Koehne) J.Wen, and Prunus gongshanensis J.Wen, with the last described herein as a new species.

American Journal of Botany, EarlyView.Abstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.

The Molecular Phylogenetic Signature of Clades in Decline
PLoS ONE, 2011 Molecular phylogenies have been used to study the diversification of many clades. However, current methods for inferring diversification dynamics from molecular phylogenies ignore the possibility that clades may be decreasing in diversity, despite the fact that the fossil record shows this to be the case for many groups.

American Journal of Botany, EarlyView.Abstract Premise Pollinator‐mediated plant‐plant interactions may be negative (i.e., competition, reproductive interference) or positive (i.e., facilitation). Especially when co‐flowering with close relatives (e.g., congeners), negative interactions through reproductive interference may be strong and result in floral trait divergence and increased ...

DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces
Applications in Plant Sciences, EarlyView.Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...
