Citizen science project on urban canids provides different results from camera traps but generates interest and revenue

open access: yesWildlife Biology, EarlyView.
As urbanization increases, wildlife increasingly encounters people. Coyotes Canis latrans and red foxes Vulpes vulpes are two canid species that have readily adapted to urban environments. Citizen science has emerged as a low‐cost method of collecting data on urban‐adapted species that can benefit management agencies but may provide different results ...

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems

open access: yesWildlife Biology, EarlyView.
Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

Consumption of anthropogenic foods influences the nutritional and reproductive condition of hunter‐harvested black bears

open access: yesWildlife Biology, EarlyView.
The consumption of human food subsidies influences ecological processes, and can affect individual behavior and fitness with population level changes in abundance and distribution. American black bears Ursus americanus often consume human food subsidies, which have been correlated with increased bear body size, age‐specific fertility and mortality ...

On the Morphology of Toponyms: What Greek Inflectional Paradigms Can Teach us

open access: yesTransactions of the Philological Society, Volume 123, Issue 1, Page 77-96, March 2025.
Abstract The research is a contribution to the investigation of the grammatical status of toponyms from the point of view of inflectional paradigmatic morphology. By examining data from Standard Modern Greek, as well as select data from its historical development, the analysis reveals that the inflectional morphology of toponyms shows significant ...
