Counting animals in orthomosaics from aerial imagery: Challenges and future directions

Methods in Ecology and Evolution
The use of drones to survey and monitor wildlife populations has increased exponentially. A common protocol used for data collection is planning flights with substantial overlap between successive photographs and lateral lines and then creating ...

An integrated approach for predicting the fate of reintroduced populations : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Conservation Biology at Massey University, Palmerston North, New Zealand [PDF]

, 2017
I provide a comprehensive account of the fate of a reintroduced population of North Island robins (Petroica longipes) at Tawharanui Regional Park, a predator-free peninsular site in the Auckland Region.

Recovery of critically endangered Nassau grouper (Epinephelus striatus) in the Cayman Islands following targeted conservation actions. [PDF]

, 2020
Many large-bodied marine fishes that form spawning aggregations, such as the Nassau grouper (Epinephelus striatus), have suffered regional overfishing due to exploitation during spawning.

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

Molecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Assessing the success of conservation translocation establishment: Post‐translocation demography of Nubian giraffe (Giraffa camelopardalis camelopardalis) in Uganda

Conservation Science and Practice
Conservation translocations are increasingly important for restoring and augmenting wild populations of extirpated species or those diminishing rapidly.

Orangutan population monitoring methods

Biological Conservation
Orangutan population sizes have been declining rapidly during the past decades. Proxies for the status of populations range from simple presence/absence data to estimations of absolute density. A variety of monitoring methods are available, including human observations, camera trapping, acoustic monitoring and aerial surveys.

Molecular characterisation of human penile carcinoma and generation of paired epithelial primary cell lines

Molecular Oncology, EarlyView.
Generation of two normal and tumour (cancerous) paired human cell lines using an established tissue culture technique and their characterisation is described. Cell lines were characterised at cellular, protein, chromosome and gene expression levels and for HPV status.
