The Amur Paradise Flycatcher ( Terpsiphone incei ) with distinct male dichromatism: implications for nest-site selection and nesting success

Journal of Field Ornithology
Nest-site selection plays a crucial role in reproductive success and survival of birds, particularly for territorial birds. Therefore, it is important to understand how birds identify and select their nesting sites.

A high incidence of non-cavity nesting in an introduced population of House Sparrows suggests that the species should not be constrained by cavity-nest site availability

Avian Research, 2017
Background The House Sparrow (Passer domesticus) has undergone dramatic population declines in many parts of Europe. It has been widely hypothesised that a lack of cavity nest sites has contributed to this decline.

Ring‐necked pheasant nest site selection in a landscape with high adoption of fall‐seeded cover crops

Wildlife Society Bulletin, 2023
Grasslands provide important nesting cover for ring‐necked pheasants (Phasianus colchicus), but they have been largely reduced with intensification of row‐cropping systems, resulting in population declines for pheasants and other grassland birds across ...

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

Molecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

Molecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Flycatchers copy conspecifics in nest-site selection but neither personal experience nor frequency of tutors have an effect. [PDF]

PLoS ONE, 2013
Using the behavior of others in guiding one's own behavior is a common strategy in animals. The prevailing theory predicts that young age and the inexperience of an individual are expected to increase the probability of adopting the behaviors of others ...

Colony and nest site selection by roseate and common terms in the Azores archipelago - a multivariate analysis [PDF]

, 1990
Multivariate techniques were used to examine overall characteristics of colonies, and detailed characteristics of nest sites within colonies, of Roseate and Common terns in the Azores archipelago.

Heterotropic regulation and negative homotropic cooperativity

FEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

IGF2 knockout reduces but does not abolish osteosarcoma growth in vitro and in vivo

FEBS Open Bio, EarlyView.
To test whether endogenous IGF2 promotes osteosarcoma growth, IGF2 was knocked out in Saos2 cells via CRISPR‐Cas9. KO cells showed reduced proliferation in vitro, and knockout xenografts in mice reached only ~25% of wild‐type tumor volume. Insulin‐like growth factor 2 (IGF2) is implicated in osteosarcoma, but direct functional evidence of its role is ...

Measuring congruence between available and selected vegetation at wild turkey nest sites

Wildlife Society Bulletin
Processes underlying nest‐site selection are often considered drivers influencing wild turkey (Meleagris gallopavo ssp.) nest success. Thus, decisions by females to identify nest sites should govern all other components of reproductive habitat selection ...
