Photo-identification and its application to gregarious delphinids: Common dolphins (Delphinus sp.) in the Hauraki Gulf, New Zealand : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Marine Ecology at Massey University, Albany, New Zealand [PDF]

open access: yes, 2016
Common dolphins (Delphinus sp.) remain one of the most poorly understood delphinids within New Zealand waters. Baseline data on their abundance, site fidelity, movement patterns, and social structure remain unknown.

Demography Meets Climate Change: Life History Challenges for a Neotropical Viviparous Lizard

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Considering the current biodiversity crisis, it is crucial to understand the impact of global environmental changes on natural populations. Analyzing demographic parameters from long‐term studies is the most effective approach to uncovering patterns that describe population dynamics.

Similar population dynamics before and after a chytridiomycosis outbreak in a tropical riparian amphibian species

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Emerging infectious diseases can cause rapid, widespread host mortality, and the lack of demographic data before and after pathogen emergence complicates understanding mechanisms of host persistence. This challenge is further compounded by environmental conditions that influence host behavior, while driving pathogen growth and virulence. These

Cryptic disease-induced mortality may cause host extinction in an apparently stable host- parasite system [PDF]

open access: yes, 2017
The decline of wildlife populations due to emerging infectious disease often shows a common pattern: the parasite invades a naive host population, producing epidemic disease and a population decline, sometimes with extirpation.

A new strategy for diagnostic model assessment in capture-recapture [PDF]

open access: yes, 2016
Common to both diagnostic tests used in capture–recapture and score tests is the idea that starting from a simple base model it is possible to interrogate data to determine whether more complex parameter structures will be supported.
