Bioenergetics of the western spruce budworm (Lepidoptera: Tortricidae) with comments on endotherm and ectotherm population energetics [PDF]

open access: yes, 1985
Energetic components (respiration, consumption, frass production, and growth) for larvae of the western spruce budworm (WSB), Choristoneura occidentalis, were modeled using multiple regression techniques for a range of temperatures (10-31°C) and body ...

Geometric factors influencing the diet of vertebrate predators in marine and terrestrial environments [PDF]

open access: yes, 2014
Predator–prey relationships are vital to ecosystem function and there is a need for greater predictive understanding of these interactions. We develop a geometric foraging model predicting minimum prey size scaling in marine and terrestrial vertebrate ...

A Case of Mortality Caused by Aeromonas hydrophila in Wild-Caught Red-Eyed Crocodile Skinks (Tribolonotus gracilis)

open access: yesVeterinary Sciences, 2019
Aeromonas hydrophila, a Gram-negative bacterium commonly found in aquatic environments, is pathogenic to amphibians, reptiles, and mammals. In human medicine, the clinical symptoms of aeromonad infection include not only gastroenteritis but also ...

Low temperatures impact species distributions of jumping spiders across a desert elevational cline. [PDF]

open access: yes, 2020
Temperature is known to influence many aspects of organisms and is frequently linked to geographical species distributions. Despite the importance of a broad understanding of an animal's thermal biology, few studies incorporate more than one metric of ...

The influence of environmental factors on pond activity of aquatic red-spotted newts Notophthalmus viridescens

open access: yesJournal of Freshwater Ecology, 2017
Many important components of animal behavior, growth, and reproduction are tightly linked to environmental conditions, particularly for ectothermic freshwater organisms.

Impacts of invasive plants on animal diversity in South Africa: A synthesis

open access: yesBothalia: African Biodiversity & Conservation, 2017
Background: Increasing numbers of invasive alien plant (IAP) species are establishing around the globe and can have negative effects on resident animal species function and diversity.

Challenges of measuring body temperatures of free-ranging birds and mammals [PDF]

open access: yes, 2015
The thermal physiology of most birds and mammals is characterised by considerable spatial and temporal variation in body temperature. Body temperature is, therefore, a key parameter in physiological, behavioural and ecological research.

The cDNA sequences of cytochrome c oxidase subunit VIa from carp and rainbow trout suggest the absence of isoforms in fishes1The sequence data in this paper have been submitted to the GenBank data library under the accession numbers: BankIt88656 U83980 (trout) and BankIt88644 U83907 (carp).1 [PDF]

open access: yes, 1997
The cDNAs of subunit VIa of cytochrome c oxidase from rainbow trout liver and carp heart are presented, revealing 82% identity of their deduced amino acid sequences. The two cDNAs are evolutionary equally distant from the livertype (VIaL) and heart-type (

On the generality of the latitudinal diversity gradient [PDF]

open access: yes, 2004
The decline of biodiversity with latitude has received great attention, but both the concise pattern and the causes of the gradient are under strong debate.

MAPPING THERMAL HABITAT OF ECTOTHERMS BASED ON BEHAVIORAL THERMOREGULATION IN A CONTROLLED THERMAL ENVIRONMENT [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Thermal environment is especially important to ectotherm because a lot of physiological functions rely on the body temperature such as thermoregulation.
