A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
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 ...

Male New Zealand robins (Petroica longipes) cater to their mate's desire when sharing food in the wild. [PDF]

, 2017
In many species that have bi-parental care, food-sharing males provide vital nutritional resources to their mates during reproduction. However, it is currently unknown whether females can signal specific desires to their mates, or if males can cater to ...

tidypopgen: Tidy population genetics in R

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 480-487, February 2026.
Abstract As genome‐wide data have become increasingly available, software libraries for their analysis have proliferated. While new tools for downstream analyses are constantly emerging, existing workflows are hindered by inefficiencies. Switching between coding languages and object types in the early stages of pipelines wastes researchers' time ...

Archaic mitochondrial DNA inserts in modern day nuclear genomes

, 2019
Traces of interbreeding of Neanderthals and Denisovans with modern humans in the form of archaic DNA have been detected in the genomes of present-day human populations outside sub-Saharan Africa.

Palaeogenomes of Eurasian straight-tusked elephants challenge the current view of elephant evolution [PDF]

, 2017
The straight-tusked elephants Palaeoloxodon spp. were widespread across Eurasia during the Pleistocene. Phylogenetic reconstructions using morphological traits have grouped them with Asian elephants (Elephas maximus), and many paleontologists place ...

What are the important landscape components for habitat selection of the ortolan bunting Emberiza hortulana in northern limit of range? [PDF]

, 2015
Ortolan buntings Emberiza hotulana have undergone one of the most severe population declines of any European farmland bird over the last thirty years. The aim of this study was to find out which habitat features, including crop characteristics,

Does Seasonal Variation in Agility of Avian Prey Influence Body Size of Breeding Male Cooper's Hawks? And Comments on the Putative Influence of Avivory on Reproductive Output in Cities

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Our findings regarding prey of breeding Cooper's Hawks in British Columbia and Wisconsin expand knowledge of their food habits and support the premise that seasonal agility of prey influences body size of nesting males. We deem it untenable to assume greater production of young at urban vs. rural nests based on proportion of avian prey use.

Exploring narratives of human–nature connections in protected areas

People and Nature, Volume 8, Issue 1, Page 37-50, January 2026.
Abstract Protected areas have become the most widespread strategy for nature conservation, and are currently expanding worldwide. Many of them are inhabited or close to inhabited areas, shaping and being shaped by connections between people and nature. These connections are not always positive.

Introduced wild pigs affect the foraging ecology of a native predator as both prey and scavenger

Wildlife Biology, Volume 2026, Issue 1, January 2026.
Introduced species can disrupt trophic interactions by acting as novel predators, prey, or scavengers. Predicting the impacts of these disruptions can be integral to the conservation of native species and the maintenance of ecological function, but is challenging, especially for species involved in multiple trophic interactions.

GEOMETRIC MODELLING OF EGG VARIABILITY IN CORVIDAE

Амурский зоологический журнал, 2015
We analyzed the egg shape in bird family Corvidae using a polynomial model and a compound ovoid model. We constructed a geometric model that reflects the relationship between cloacal and infundibular arcs, and the length and the diameter of the egg ...
