Foraging Observations: Novel Trophic Interactions Between the Andean Gull (<i>Chroicocephalus serrranus</i>) and Endangered Vertebrates of Lake Titicaca. [PDF]

Ecol Evol
We show that the Andean gull predates on both the Titicaca Grebe and the Titicaca Giant Frog. Both these species are critically endangered, and it was unknown that they had natural predators before this. ABSTRACT We record two new predation events and one new kleptoparasitic Andean Gull (Chroicocephalus serranus) behavior, interactions that directly ...

Blood Relatives: Linking Evolutionary History and Conservation of Medicinal Leeches (<i>Hirudo</i> spp.). [PDF]

Evol Appl
ABSTRACT Medicinal leeches of the genus Hirudo are both historically important in medicine and increasingly studied as models in ecology and biomedicine. However, the taxonomy, population structure and evolutionary history of this genus remain partially unresolved.

WABAD: A world annotated bird acoustic dataset for passive acoustic monitoring. [PDF]

Ecology
Abstract Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers.

Recommendations for Improving the Modeling of Wintering Waterbird Population Sizes and Trends. [PDF]

Ecol Evol
We assessed four statistical approaches (simple GLMM, optimized GLMM, LORI, and TRIM) for analyzing International Waterbird Census data and found that commonly used methods inadequately address zero inflation, overdispersion, and spatial autocorrelation.

A New Species of Plasmodium of the Subgenus Novyella Infecting White-Shouldered Fire-Eyes (Pyriglena leucoptera) (Aves: Thamnophilidae) in Brazil. [PDF]

Integr Zool
South America has a remarkable genetic diversity of avian haemosporidians, yet only a few species have been described combining molecular and morphological data. This study introduces Plasmodium (Novyella) pyriglenae sp. nov., a new species infecting the white‐shouldered fire‐eye (Pyriglena leucoptera) in Brazil.

Faeces, Feathers and Flight: Understanding of Escape Behaviour in Incubating Eurasian Woodcocks (<i>Scolopax rusticola</i>). [PDF]

Ecol Evol
Using a large dataset of nest photographs from open‐source platforms, we investigated defecation and fright moulting in incubating Eurasian woodcocks (Scolopax rusticola), finding defecation in 54% of nests and feathers in 67%. We suggest these behaviours may aid the female's escape rather than protect the nest, and highlight the importance of ...
