Challenges of Monitoring Endangered Bryde's Whales During a Period of Rapid Environmental Change

open access: yesAnimal Conservation, EarlyView.
Estimating population size is challenging for rare and elusive species that occur at low densities and are difficult to detect during sampling. We estimated the abundance of a Nationally critical whale species—Aotearoa New Zealand Bryde's whales—using a custom‐formulated POPAN model which incorporated transience to account for their complex residency ...

Differential segment‐specific signalling pathways for guanylate cyclase C‐activated anion secretion in murine ileocolon

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Guanylate cyclase‐C (GC‐C) is the receptor for endogenous (uro)guanylin peptides, bacterial toxins and pharmacological analogues. Receptor activation leads to intestinal fluid loss, but also activates an antiproliferative pathway and is a promising target in colorectal cancer therapy.
