Phylogenetic definitions for Dipsacales, Adoxaceae, and Caprifoliaceae
Bulletin of Phylogenetic NomenclatureFormal phylogenetic definitions are here provided for the angiosperm clades Dipsacales, Adoxaceae, and Caprifoliaceae. After decades of progress in understanding the phylogeny of Asteridae and Campanulidae, the three clades here associated with those ...

The Role of Plant Evolutionary History in Shaping the Variation in Specific Leaf Area Across China. [PDF]
Ecol EvolIn this study, we analyzed the influences of climatic conditions and soil properties on the specific leaf area (SLA), calculated the phylogenetic signals of SLA, and quantified the relative contributions of evolutionary history to the spatial variation in SLA. We underscored the importance of evolutionary history in shaping the spatial variation of SLA

Herbivory Dominates the Spring Diet of American Black Bears (<i>Ursus americanus</i>) in a Wood Bison (<i>Bison bison athabascae</i>) Neonatal Range, Suggesting Minimal Bison Consumption. [PDF]
Ecol EvolIn this study, we used scat analysis and DNA metabarcoding to analyze the spring diet of black bears in the neonatal range of a small, threatened wood bison herd in northeast Alberta to assess predation risk of neonate bison. Our results suggest that consumption rates of bison are low and that predation risk to neonate wood bison, during the RLBH's ...

Duplications and expression of DIVARICATA-like genes in dipsacales. [PDF]
Molecular Biology and Evolution, 2009 The genetics underlying flower symmetry shifts between radial and bilateral symmetry has been intensively studied in the model Antirrhinum majus. Understanding the conservation or diversification of this genetic pathway in other plants is of special interest in understanding angiosperm evolution and ecology. Evidence from Antirrhinum indicates that TCP

Climate adaptation and functional constraints drive pollen evolution in Apiales. [PDF]
New PhytolSummary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

Phenolic compounds in species of the Blechnaceae. [PDF]
Plant Biol (Stuttg)The occurrence of caffeic acid derivatives in 32 species of Blechnaceae revealed differences in the presence of rosmarinic acid and blechnic acid B, a novel compound in ferns. Abstract Rosmarinic acid and other caffeic and 4‐coumaric acid derivatives are widespread in land plants.

Perspectives in Biosecurity, 2022 Aotearoa / New Zealand harbours more naturalised non-native plant species than almost any other island group in the world, some of which are serious threats to indigenous biodiversity. Japanese honeysuckle (Lonicera japonica), a non-native climbing vine,

Combining historical biogeography with niche modeling in the Caprifolium clade of Lonicera (Caprifoliaceae, Dipsacales). [PDF]
Systematic Biology, 2010 The Lonicera clade Caprifolium contains approximately 25 species distributed around the Northern Hemisphere, including in the Mediterranean climates of California and Europe. We sequenced the second intron of LFY to help resolve relationships within the clade where the internal transcribed spacer and chloroplast markers had previously failed to do so ...

Progestogens and androgens influence root morphology of angiosperms in a brassinosteroid-independent manner. [PDF]
Plant JSignificance Statement Plants produce progesterone and androgens, which alter root morphology in A. thaliana and 60% of tested angiosperms. Brassinosteroids seem uninvolved. Understanding the mechanism is like navigating an unknown city—exemplarily Dittelbrunn (a small village in Bavaria)—where the expected shortcut (interaction with brassinosteroids ...
