How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I am a PhD researcher on Cohort 5 of the London NERC DTP, based at the Institute of Zoology and University College London. My PhD project focuses on investigating hatching failure in managed captive and wild endangered bird populations, distinguishing the factors leading to infertility and early embryo death in these populations and examining the management techniques and egg manipulation procedures which are utilised to maximise hatching success. More broadly, I am interested in behavioural ecology, conservation, and sustainability.
Reproductive failure is ubiquitous. However, research on the mechanisms underpinning reproductive failure is still lacking in most species. This gap in our understanding has particularly strong repercussions for threatened species and it hinders our ability to establish effective interventions to improve survival. In this review, we focus on why eg...
Analyses of phenotypic integration and modularity seek to quantify levels of covariation among traits to identify their shared functional, developmental and genetic underpinnings ('integration'), which may delineate semi-independent subsets of highly integrated traits ('modules'). Existing studies have focused mainly on mammals or model organisms,...
Ecosystem collapse, i.e. the endpoint of ecosystem decline, is a central concept of IUCN Red List of Ecosystems (RLE) assessments and the identification of ecosystems most vulnerable to global environmental change. Estimating collapse risk can be challenging for ecosystems reliant on a few dominant species to perform most of their functions because...
