Increased songbird nest depredation due to Aleppo pine (Pinus halepensis) encroachment in Mediterranean shrubland

BMC Ecology, 2019
Background In recent decades, a decrease of passerine densities was documented in Mediterranean shrublands. At the same time, a widespread encroachment of Aleppo pines (Pinus halepensis) to Mediterranean shrubland occurred.

Forest Bird Abundance Is Linked to the Interactions Between Forest Characteristics and Species Ecological Traits: Implications for Forest Management. [PDF]

Ecol Evol
Using extensive bird monitoring data from Czechia and detailed forest and species trait information, this study found strong interactions between bird traits—especially migration distance and habitat specialization—and forest characteristics. These findings highlight the need for targeted forest management strategies, such as coppicing or old‐growth ...

Analysis of the human Y-chromosome haplogroup Q characterizes ancient population movements in Eurasia and the Americas [PDF]

, 2019
Background: Recent genome studies of modern and ancient samples have proposed that Native Americans derive from a subset of the Eurasian gene pool carried to America by an ancestral Beringian population, from which two well-differentiated components ...

In situ aerial bioacoustic monitoring from extremely noisy drone recordings

Methods in Ecology and Evolution, EarlyView.
Abstract Aerial bioacoustic monitoring has the potential to transform biodiversity surveys by enabling rapid acoustic sampling across large and inaccessible habitats. However, its application from unmanned aerial vehicles (UAVs) has remained limited because strong rotor self‐noise overwhelms target sounds such as bird vocalisations, compromising the ...

Pigeon and Poultry Breeders, Friends or Enemies of the Northern Goshawk Accipiter gentilis? A Long-Term Study of a Population in Central Poland

Animals, 2019
In this study, we focused on a goshawk population in central Poland (study area 105 km2, forests 24 km2, seven small forest complexes) which was monitored long-term (with high densities recorded in the 1980s of 16.3 pairs/100 km2 despite persecution by ...
