The Effect of Assisted Reproductive Technologies on Human Sex Ratios

open access: yesAustralian and New Zealand Journal of Obstetrics and Gynaecology, EarlyView.
ABSTRACT Background Modern assisted reproductive technology (ART), including pre‐implantation genetic testing for aneuploidy (PGT‐A), has opened new avenues in understanding early embryonic events and has simultaneously raised questions about the impact of ART itself on sex ratios.

Functional characterisation of constitutive expresser of pathogenesis-related genes 5 : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Molecular Biology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2017
As reported previously, CPR5 negatively regulates the onset of leaf death, hypersensitive response, disease resistance and early leaf senescence. cpr5 plants contain aberrant trichomes and higher levels of ROS, SA and JA.

The BioColour Library

open access: yesColoration Technology, EarlyView.
Abstract The attraction of adopting natural and bio‐based colourants in applications has grown, but their use suffers from a lack of certification bodies, standards and reference data. In the BioColour project, we are developing an open database and tools for the characterisation, authentication and quality analysis of biocolourant sources ...

Inferring Variation in Copy Number Using High Throughput Sequencing Data in R

open access: yesFrontiers in Genetics, 2018
Inference of copy number variation presents a technical challenge because variant callers typically require the copy number of a genome or genomic region to be known a priori.

Reproductive biology of invasive grass carp (Ctenopharyngodon idella) in two North American systems

open access: yesJournal of Fish Biology, EarlyView.
Abstract Grass carp (Ctenopharyngodon idella) are nonnative, herbivorous freshwater fish that represent an ecological threat in North American waters. However, data are limited on reproductive biology specific to wild populations in midwestern North America, despite recent concern for grass carp establishment within the Great Lakes.

Acclimation conditions and subsequent acute hypoxia challenges do not affect the frequency of erythrocyte nuclear segmentation in triploid brook charr Salvelinus fontinalis (Mitchill 1814)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Routine observations of blood smears have repeatedly shown that triploid fish have a greater proportion of erythrocytes with nuclear segmentation (ENS) than diploids; however, there is as yet no understanding of why this is the case and whether it affects erythrocyte function.
