Vocalisations of the New Zealand morepork (Ninox novaeseelandiae) on Ponui Island : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2015
Vocalisations provide an effective way to overcome the challenge of studying the behaviour of cryptic or nocturnal species. Knowledge of vocalisations can be applied to management strategies such as population census, monitoring, and territory mapping ...

Host Exploitation by Cuckoos in China: A Review and Real‐Time Tracking Program for Parasitism Records

open access: yesIntegrative Zoology, EarlyView.
China is a global hotspot for cuckoo‐host diversity, with 17 cuckoo species, exploiting 142 host species. We reveal adaptive matching in body size and egg traits, along with niche partitioning among cuckoos, while identifying eight new host species.

New sounds and extended composition techniques [PDF]

open access: yes, 2012
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This commentary supports my PhD composition portfolio. The composition processes of each piece are related to my central research questions, which concern ...

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

open access: yesIntegrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

Deer browsing alters sound propagation in temperate deciduous forests.

open access: yesPLoS ONE, 2019
The efficacy of animal signals is strongly influenced by the structure of the habitat in which they are propagating. In recent years, the habitat structure of temperate forests has been increasingly subject to modifications from foraging by white-tailed ...

Senescence of song revealed by a long-term study of the Seychelles warbler (Acrocephalus sechellensis)

open access: yesScientific Reports, 2020
Senescence is widespread in nature, often resulting in diminishing survival or reproduction with age, but its role in age-dependent variation in sexual traits is often poorly understood. One reason is that few studies of sexual traits consider non-linear

A microtonal wind controller building on Yamaha’s technology to facilitate the performance of music based on the “19-EDO” scale [PDF]

open access: yes, 2016
We describe a project in which several collaborators adapted an existing instrument to make it capable of playing expressively in music based on the microtonal scale characterised by equal divsion of the octave into 19 tones (“19-EDO”).

Genomic Content in Avian Haemosporidian Parasites Suggests Co‐Regulation of Apicoplast and Mitochondrial Nucleoids

open access: yesIntegrative Zoology, EarlyView.
Apicoplast genomic content and mitochondrial genomic content were found to be strongly correlated (rho = 0.93) for infections going from low to high. Apicoplast and mitochondrial genomic content were deemed as more predictive factors of parasitemia for different infection intensities.

Age effect of deafening on stereotyped song maintenance in adult male bengalese finches Lonchura striata domestica

open access: yesCurrent Zoology, 2009
Birdsong is a complex learned vocal behavior that relies on auditory experience for development. However, it appears that among different species of close-ended songbirds, there are some variations in the necessity of auditory feedback for maintaining ...

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

open access: yesIntegrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...
