Phylogenetic systematics of Juncaceae. [PDF]

open access: yesAm J Bot
Abstract Premise Juncaceae has needed taxonomic revision for some time. Specifically, the genus Juncus s.l. is known to be paraphyletic because five small southern‐hemisphere genera have been shown repeatedly to be nested within it. In 2022, a new classification was proposed, based on phylogenies built from one nuclear and three plastid regions ...

One Century of Change: Stronger Diversity Decline in Lowland Than in Mountain Grasslands in Central Europe. [PDF]

open access: yesGlob Chang Biol
Written Summary: We resampled 416 historical vegetation records (originally sampled between 1884 and 1931) from grasslands across Switzerland at a wide range of elevations and moisture levels. We found severe declines in alpha, beta, and gamma taxonomic diversity as well as functional and phylogenetic alpha diversity over the last century.

A Recent Lineage Split in <i>Cladium mariscus</i> Preceding the Disjunction of Two Biodiversity Hotspots: Evidence From Plastid Genomes. [PDF]

open access: yesEcol Evol
Our complete plastome analysis of Cladium mariscus reveals a Late Pleistocene divergence (~68.5 kya) between disjunct Tibetan (Bomi) and Yunnanese (Ninglang) populations—predating the tectonic disjunction of the Hengduan and Yarlung Tsangpo biodiversity hotspots.

Phylogenomic Barcoding of Soil Seed Bank-Persistent and Wind-Dispersed Non-Native Plant Species in South Georgia. [PDF]

open access: yesMol Ecol Resour
ABSTRACT Climate change and invasive species are leading drivers of biodiversity loss, with island ecosystems being especially vulnerable. South Georgia, a remote sub‐Antarctic island, is 170 km long with approximately 30,000 ha of vegetated coastal areas, as snow and ice dominate the inland regions.

Mowing Modulates the Biotic Filter of Expansive Species. [PDF]

open access: yesEcol Evol
Management type and expansive species influence plant community diversity in complex ways. Overall increase of expansive species cover acts as biotic filter in reducing the alpha and beta taxonomic and phylogenetical diversity. However, the filtering effect is modulated by management type, being more intense under mown grasslands.

Metabarcoding Reveals Fine Scale Patterns of Trophic Resource Use and Partitioning Along Gradients of Land Use and Deer Density in a Multi-Species Ungulate Community. [PDF]

open access: yesEcol Evol
We used DNA metabarcoding of 2,568 fecal samples to examine seasonal diets and resource partitioning among four deer species (moose, roe deer, red deer, fallow deer) across two Swedish landscapes. Deer consumed a wide range of plants, but diets were typically dominated by a few key taxa, with distinct dietary separation between moose and smaller deer ...
