Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

open access: yesWildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

A Tale of Appendages: Investigating Limb and Tail Variation in Salamanders

open access: yesIntegrative Zoology, EarlyView.
We analyzed limb and tail proportions in 44% of known salamander species using a phylogenetic comparative approach. Our results revealed significant variation among families and ecological groups, with aquatic species showing longer limbs and basal lineages having shorter tails.

Counting Real Connected Components of Trinomial Curve Intersections and m-nomial Hypersurfaces

open access: yes, 2002
We prove that any pair of bivariate trinomials has at most 5 isolated roots in the positive quadrant. The best previous upper bounds independent of the polynomial degrees were much larger, e.g., 248832 (for just the non-degenerate roots) via a famous ...

Species‐Specific Genetic Patterns in Sympatric Freshwater Turtles Challenge a Generalized Multi‐Species Conservation Approach

open access: yesAnimal Conservation, EarlyView.
We compared genetic diversity and spatial genetic structure in the snapping turtle (Chelydra serpentina; left panel), Blanding's turtle (Emydoidea blandingii; bottom right), and spotted turtle (Clemmys guttata; top right) sampled in areas of co‐occurrence across ~49,160 km2.

NEWT, a new taxonomy portal [PDF]

open access: yesNucleic Acids Research, 2003
NEWT is a new taxonomy portal to the SWISS-PROT protein sequence knowledgebase. It contains taxonomy data, which is updated daily, for the complete set of species represented in SWISS-PROT, as well as those stored at the NCBI. Users can navigate through the taxonomy tree and access corresponding SWISS-PROT protein entries.

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

open access: yesAndrology, EarlyView.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

An examination of core beliefs in generalized anxiety disorder

open access: yesBritish Journal of Clinical Psychology, EarlyView.
Abstract Objective Generalised anxiety disorder (GAD) is characterised by uncontrollable worries. Cognitive behaviour therapy (CBT) is an effective treatment for GAD; however, manualised treatments rarely include interventions to target core beliefs. This study aimed to (1) explore the core beliefs about the self that are endorsed by individuals with ...

How Has the Rise of Direct‐To‐Consumer Genetic Testing Impacted Genetic Counselling Practice? A Scoping Review

open access: yesClinical Genetics, EarlyView.
This scoping review consolidated research on genetic health practitioners' (GHPs) and direct to consumer genetic testing (DTC‐GT) consumer needs and identified gaps. Thematic analysis identified four domains: GHPs' views, GHPs' perceptions of the impact of DTC‐GT on consumers, how DTC‐GT impacted services and how DTC‐GT impacted roles.
