The PteridoPortal: A publicly accessible collection of over three million records of extant and extinct pteridophytes. [PDF]

Appl Plant Sci
Abstract Premise Pteridophytes—vascular land plants that disperse by spores—are a powerful system for studying plant evolution, particularly with respect to the impact of abiotic factors on evolutionary trajectories through deep time. However, our ability to use pteridophytes to investigate such questions—or to capitalize on the ecological and ...

A preliminary world checklist of fern-mining insects [PDF]

Biodiversity Data Journal, 2021
Compared to the leaf-miners and stem-miners on flowering plants, the miners on ferns (including both Lycopodiophyta and Polypodiophyta in the broad sense) are less known.

The Role of Forage Quantity and Quality in the Migration and Diet of a Northern Ungulate During Their Neonatal Period. [PDF]

Ecol Evol
In this article, we examined the differences in forage quantity and quality between two defined ranges of a wood bison population as an attempt to identify possible factors influencing their migration during the neonatal period. We found significant differences in the forage quantity and quality between ranges, suggesting a link between these factors ...

Structure of Equisetum variegatum (Equisetaceae) populations in natural and anthropogenic habitats

Botanica, 2023
Many native plant species colonise anthropogenic habitats, but relatively little information is available on the status and development of their populations under unusual conditions.

Variation in stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope compositions along antlers of Qamanirjuaq caribou (Rangifer tarandus groenlandicus). [PDF]

Ecol Evol
Stable isotopes in antler tissue may provide a non‐lethal means of studying short and long‐term changes in caribou ecology. Carbon and Nitrogen isotopes of antler collagen showed variation from pedicle to tip and varied among the individuals sampled.
