Fine‐scale genetic structure of the cloud forest tree Ocotea psychotrioides revealed by genome‐wide SNP data

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Recent advances in genomic technologies now enable the reconstruction of evolutionary histories at fine spatial scales, illuminating the complex dynamics that shape biodiversity patterns in naturally discontinuous, archipelago‐like ecosystems such as cloud forests.

Comparative Profiles of Lipophilic Nutrients and In Vitro Antioxidant Activity in Commercial Arabica and Robusta Green Coffee Beans

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
Integrated compositional profiling of ten commercial green coffee lots showed higher mean total phenolic content, DPPH radical‐scavenging activity, β‐carotene, and total phytosterols in Robusta‐labeled lots, whereas Arabica‐labeled lots showed higher mean total tocopherols and total measured fatty acids.

Scale‐space image analysis for mapping spotted knapweed in grassland ecosystems

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise This study investigates the value of scale‐space representations of spatial features for the identification and mapping of invasive plants using high‐resolution multispectral imagery. Scale‐space representations combine the two‐dimensional spatial domain with a third dimension representing spatial scale, such that features can be ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe 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 ...

Oribatid mite (Acari: Oribatida) species inventory on an altitudinal gradient in the Piatra Craiului Mountains (Southern Carpathians, Romania)

open access: yesTravaux de l'Institut de Speologie Emile Racovitza, 2017
Oribatid mite species from Piatra Craiului Mountains (Southern Carpathians, Romania) were studied according to their altitudinal distribution. The mites were sampled from four sites (beech forest, fir and beech forest, nude scree and subalpine grassland)

Changes in the taxonomic and functional composition of fishes along the altitudinal gradient of the Piedmont-Lowland in the Meta River basin

open access: yesNeotropical Ichthyology
Altitudinal gradients provide a natural framework for evaluating how fish communities respond to environmental variation at both local and regional scales.

Clade‐wide morphological and functional variation of the sauropsid columella

open access: yesThe Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.
