A Conceptual Framework and Methods for Studying the Connectivity of Fishes

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Integrative phylogenomics and morphology reveal the evolution and biogeography of Encephalartos (Zamiaceae)

open access: yesJournal of Systematics and Evolution, EarlyView.
We aimed to conduct phylogenetic analyses of Encephalartos, a cycad genus endemic to Africa, using 3545 single‐copy nuclear genes extracted from transcriptome data, covering 64/65 of the recognized species, along with inference of divergence times using two secondary calibration points.

Comparative evaluation of the attractiveness of new polyethylene screens versus West African tiny target for the control of tsetse flies

open access: yesMedical and Veterinary Entomology, EarlyView.
The material has no significant difference in captures (non‐shiny cotton‐polyester screens vs. the shiny polyethylene screens), but the vertical screen attracted significantly more G. tachinoides for each type of material. Full white horizontal screen was significantly lower than the reference WATT.

Gall responses to drying habitats: Insights from the community of galling herbivores associated with the superhost Caryocar brasiliense Cambess. (Caryocaraceae)

open access: yesPlant Biology, EarlyView.
Drying processes in the Brazilian palm swamps or Veredas, impact the gall community in adjacent vegetation by reducing the abundance of more sensitive galls, while more resilient galls acclimate to increased dryness by developing thicker protective tissues. Abstract Galls are new plant organs formed in response to the stimuli of gall‐inducing organisms,

Validating habitat suitability assessments with post‐translocation animal movement data

open access: yesRestoration Ecology, EarlyView.
Wildlife translocations are essential for restoring species to their native habitats, and species distribution models (SDMs) have proven useful for identifying suitable habitats to guide this process. Validating model predictions with data from individual's post‐translocation, however, is rare due to the frequent lack of monitoring data from ...
