The effects of acoustic misclassification on cetacean species abundance estimation
(2013-12-25) - Journal article
To estimate the density or abundance of a cetacean species using acoustic detection data, it is necessary to correctly identify the species that are detected. Developing an automated species classifier with 100% correct ...
Imperfect observations in ecological studies
(2016-09) - Journal article
Every ecological data set is the result of sampling the biota at sampling locations. Such samples are rarely a census of the biota at the sampling locations and so will inherently contain biases. It is crucial to account ...
Movement and biosonar behavior during prey encounters indicate that male sperm whales switch foraging strategy with depth
(2018-11-28) - Journal article
Despite their apex predator role, relatively little is known about the foraging strategies that deep-diving marine mammals employ to target prey resources available at different depths with different costs of access. Using ...
A novel Meloidogyne incognita chorismate mutase effector suppresses plant immunity by manipulating the salicylic acid pathway and functions mainly during the early stages of nematode parasitism
(2018-03-15) - Journal article
Meloidogyne incognita is the most economically important plant-parasitic nematode. M. incognita manipulates plant cell development and metabolism by injecting effectors from the esophageal glands into the plant host. ...
Gradients in predation risk in a tropical river system
(2018-04-01) - Journal article
The importance of predation risk as a key driver of evolutionary change is exemplified by the Northern Range in Trinidad, where research on guppies living in multiple parallel streams has provided invaluable insights into ...
Cognitive ability is heritable and predicts the success of an alternative mating tactic
(2015-06-22) - Journal article
The ability to attract mates, acquire resources for reproduction, and successfully outcompete rivals for fertilisations may make demands on cognitive traits - the mechanisms by which an animal acquires, processes, stores, ...
Species richness in marine phytoplankton communities is not correlated to ecosystem productivity
(2013-08-15) - Journal article
Divergent mechanisms of acoustic mate recognition between closely related field cricket species (Teleogryllus spp.)
(2017-08) - Journal article
Effective recognition of conspecific mating signals reduces the risk of maladaptive hybridization. Dissecting the signal recognition algorithms that underlie preferences is a useful approach for testing whether closely ...
How insightful is ‘insight’? New Caledonian crows do not attend to object weight during spontaneous stone dropping
(2016-12-14) - Journal article
It is highly difficult to pinpoint what is going through an animal’s mind when it appears to solve a problem by ‘insight’. Here, we searched for an information processing error during the emergence of seemingly insightful ...
Summer at the beach : spatio-temporal patterns of white shark occurrence along the inshore areas of False Bay, South Africa
(2018-05-22) - Journal article
Background: Understanding white shark (Carcharodon carcharias) habitat use in coastal areas adjacent to large cities, is an important step when formulating potential solutions to the conservation conflict that exists ...
