The exercise sex gap and the impact of the estrous cycle on exercise performance in mice

open access: yesScientific Reports, 2018
Exercise physiology is different in males and females. Females are poorly studied due to the complexity of the estrous cycle and this bias has created an exercise sex gap.

Fly pollinator foraging in boreal forests is shaped by climate, forest structure and flower resources

open access: yesOikos, EarlyView.
Most insect pollinators are ectothermic and rely on external heat sources for temperature regulation. Forests, with their diverse canopy structures and sunlight penetration levels, create a mosaic of microclimates influencing these insects' behaviour.

The effect of seawater on thermoregulator centers [PDF]

open access: yes
Experiments were done on dogs to determine the mechanism of thermoregulation. Results show that natural seawater, injected intravenously (150, 200, and 300 cc ), causes narcosis of the thermic centers and increases temperature. Diluted seawater injection

The effect of fructose and maltodextrin vs glucose and maltodextrin formulated sports beverages on mountain-bike race performance : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Sport and Exercise Science at Massey University, Wellington, New Zealand [PDF]

open access: yes, 2007
Background: Exogenous carbohydrate improves performance during prolonged high-intensity exercise. When ingested together, fructose and glucose polymers are oxidised at rates 1.5-1.7 higher than isocaloric glucose solutions.

Latitude‐specific responses of European birds' population growth rates to temperature and water availability

open access: yesOikos, EarlyView.
Climate limits distribution of species and shows considerable regional variability. However, studies relating climate variation to species population growth rates in different climatic zones while accounting for species' ecological traits are scarce.

The circadian system alters thermoregulation depending on the time of day and feeding condition [PDF]

open access: yes, 2009
The circadian rhythm of body temperature (Tb) is a well-known phenomenon. However, it is unknown how the circadian system affects thermoregulation. Food deprivation in mice induces a greater reduction of Tb particularly in the light phase.

Triiodothyronine suppresses humoral immunity but not T-cell-mediated immune response in incubating female eiders (Somateria mollissima)

open access: yes, 2007
Immunity is believed to share limited resources with other physiological functions and this may partly account for the fitness costs of reproduction. Previous studies have shown that the acquired immunity of female common eiders (Somateria mollissima) is

Predators and scavengers: Polar bears as marine carrion providers

open access: yesOikos, EarlyView.
Scavenging is a foraging strategy widely used across the animal kingdom and apex predators provide a large amount of energy in a food web by provisioning carrion. In the harsh environmental conditions of the Arctic, apex predators such as polar bears Ursus maritimus can provide scavenging opportunities for many species. Carrion can act as a buffer when
