Determining trophic niche width: a novel approach using stable isotope analysis [PDF]

open access: yes, 2004
1. Although conceptually robust, it has proven difficult to find practical measures of niche width that are simple to obtain, yet provide an adequate descriptor of the ecological position of the population examined. 2.

The Effect of Digestive Capacity on the Intake Rate of Toxic and Non-Toxic Prey in an Ecological Context. [PDF]

open access: yesPLoS ONE, 2015
Digestive capacity often limits food intake rate in animals. Many species can flexibly adjust digestive organ mass, enabling them to increase intake rate in times of increased energy requirement and/or scarcity of high-quality prey.

First report of lionfish prey from Western Florida waters as identified by DNA barcoding [PDF]

open access: yesPeerJ, 2020
DNA barcoding was used to identify prey fragments recovered from the stomachs of lionfish harvested during the 2016 Sarasota Lionfish Derby. A total of 305 prey fragments were recovered from 50 stomachs (mean = 4.6 per stomach), of which 184 (60.3 ...

Colour change and assortment in the western rainbowfish [PDF]

open access: yes, 2010
Grouping behaviour is widespread across the animal kingdom, and is known to reduce an individual's risk of predation, for example through predator confusion.

Spotted hyaena Crocuta crocuta feeding ecology and selectivity of large herbivorous prey in the Namib desert

open access: yesEcology and Evolution, 2021
We have investigated the relationship between spotted hyaenas in the south Namib Desert and large herbivorous prey and have summarized an updated overview of predator‐prey relationships in this resource‐limited arid environment.

Taste and the algorithm [PDF]

open access: yes, 2018
Today, a consistent part of our everyday interaction with art and aesthetic artefacts occurs through digital media, and our preferences and choices are systematically tracked and analyzed by algorithms in ways that are far from transparent.

Plant Resources as a Factor Altering Emergent Multi-Predator Effects. [PDF]

open access: yesPLoS ONE, 2015
Multiple predator effects (MPEs) can modify the strength of pest regulation, causing positive or negative deviations from those that are predicted from independent effects of isolated predators.
