Predator declines and morphological changes in prey: Evidence from coral reefs depleted of sharks

Predator declines and morphological changes in prey: Evidence from coral reefs depleted of sharks

by jjmeeuwig | Jan 15, 2018 | Publication, Shanta Barley, Jessica Meeuwig

Evidence from the wild as to the ecological and evolutionary consequences of top predator depletions remains limited, especially in marine systems. Given the pace and extent of predator loss, an understanding of these processes is important. Two sets of adjacent coral reef systems …

Diet and condition of mesopredators on coral reefs in relation to shark abundance

Diet and condition of mesopredators on coral reefs in relation to shark abundance

by jjmeeuwig | Apr 19, 2017 | Publication, Shanta Barley, Jessica Meeuwig

Reef sharks may influence the foraging behaviour of mesopredatory teleosts on coral reefs via both risk effects and competitive exclusion. We used a “natural experiment” to test the hypothesis that the loss of sharks on coral reefs can …

Species diversity, abundance, biomass, size and trophic structure of fish on coral reefs in relation to shark abundance

Species diversity, abundance, biomass, size and trophic structure of fish on coral reefs in relation to shark abundance

by jjmeeuwig | Feb 17, 2017 | Publication, Shanta Barley, Jessica Meeuwig

Theory predicts that loss of gape-limited sharks should lead to increases in the abundance and biomass of smaller size classes of prey. We used stereo-baited remote underwater video stations (stereo-BRUVS) …

Dr. Shanta Barley goes in search of the elusive platypus

by jjmeeuwig | Sep 23, 2016 | Media, Spotlight, Shanta Barley

Check out the new show on BBC One in which our postdoc Dr Shanta Barley goes in search of that elusive evolutionary oddity, the platypus. Entitled “Bodies”, the episode explores the anatomical secrets of some of the weirdest animals on Earth. The platypus is an egg-laying mammal …

The power and the pitfalls of large-scale, unreplicated natural experiments

The power and the pitfalls of large-scale, unreplicated natural experiments

by jjmeeuwig | Aug 29, 2016 | Publication, Shanta Barley, Jessica Meeuwig

Large-scale, unreplicated natural experiments (LUNEs) have a unique power to test hypotheses at ecologically realistic scales and have delivered in-sights of great power into cosmology, evolution and geology. Yet, LUNEs are relatively rare in the …

You ain’t seen knotting yet – novel feeding behaviours in moray eels

You ain’t seen knotting yet – novel feeding behaviours in moray eels

by jjmeeuwig | Oct 8, 2015 | Publication, Shanta Barley, Jessica Meeuwig

We report observations of a novel feeding behaviour in the moray eel Gymnothorax favagineus (Bloch & Schneider, 1801) and a previously undocumented application of “knotting” behaviour in G. fimbriatus (Bennett, 1832). Moray eels were filmed …
