Population Processes of Genetic Divergence in Palearctic Buzzards During the Late Pleistocene: Advance Report

open access: yesПернатые хищники и их охрана, 2018
Our study illustrates how complex population processes over the Late Pleistocene have shaped the patterns of genetic divergence in Palearctic buzzards, due to the effects of population expansions and contractions, with hybridization at contact zones ...

Unsaturated Phosphine Oxides for Modular Antibody Rebridging and Single Reagent Peptide‐Cyclisation‐Bioconjugation

open access: yesAngewandte Chemie International Edition, Accepted Article.
Achieving modular, selective and homogeneous protein modifications is of utmost importance for the design of next generation biopharmaceuticals; especially in the context of antibody‐drug conjugates (ADCs). Here, we introduce unsaturated phosphine oxides as versatile triple‐reactive reagents, allowing orthogonal chemoselective bioconjugation schemes ...

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

open access: yesThe Anatomical Record, EarlyView.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

The Relationship Between Water Level, Prey Availability and Reproductive Success in Roseate Spoonbills Foraging in a Seasonally-Flooded Wetland While Nesting in Florida Bay [PDF]

open access: yes, 2014
The coastal wetlands of northeastern Florida Bay are seasonally-inundated dwarf mangrove habitat and serve as a primary foraging ground for wading birds nesting in Florida Bay.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Cats kill millions of vertebrates in Polish farmland annually

open access: yesGlobal Ecology and Conservation, 2019
We estimated the predation rate by free ranging domestic cats on vertebrates in rural areas of central Poland. We performed a door-to-door survey on the number of cats owned and type of food provided and combined results of the survey with the previous ...
