Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Overwintering performance of Nile tilapia Oreochromis niloticus (L.) broodfish and seed at ambient temperatures in northern Vietnam

, 2000
Two experiments (E1 and E2) to assess the performance of tilapia broodstock and tilapia sex-reversed fry in overwintering were conducted at the Research Institute for Aquaculture No.1 (RIA-1) in the cold seasons of 1995–96 and 1996–97.

Weathering the storm: Most maternal and environmental drivers of individual reproductive success do not scale up to population recruitment in a large herbivore

Journal of Animal Ecology, EarlyView.
Using 18 years of data on eastern grey kangaroos, we show that drivers of individual reproductive success often do not scale up to population recruitment. Birth asynchrony could buffer population recruitment against environmental variability, such that variables affecting individual reproduction have little impact at the population level.

Cold hardiness and overwintering survival of the grain aphid Sitobion avenae in Northern England [PDF]

, 1987
Laboratory maintained Sitobion avenae of all developmental stages had a mean inherent supercooling ability below -20°C. Acclimation alone, or in conjunction with starvation had no significant effect on supercooling.

Continuous acoustic studies of overwintering sprat Sprattus sprattus reveal flexible behavior

, 2012
The clupeid fish Sprattus sprattus was studied in a 150 m deep Norwegian fjord throughout an entire overwintering period during which the fjord froze over and a major water renewal occurred.

Early‐life environment drives long‐term decrease in adult body mass in a wild bird population

Journal of Animal Ecology, EarlyView.
Using more than 90,000 body mass measures of adult and nestling great tits Parus major, we show that the 1 SD decline in adult mass between 1978 and 2024 is a consequence of changes in the environment (i.e. increase in population density) experienced at early life.

Behavior and ecology of overwintering sprat Sprattus sprattus

, 2017
Sprat Sprattus sprattus is a marine, forage fish of high ecological and economical value. This thesis addresses the ecology and behavior of sprat during overwintering, a phase that is poorly studied in marine pelagic fish.

Playing with fire: Wolf response to active wildfires, fire fronts and smoke

Journal of Animal Ecology, EarlyView.
This study is one of the first, to our knowledge, to explicitly examine fine‐scale behavioural responses of a large carnivore to actively burning wildfires, fire fronts and smoke. The study found that wolves balanced the potential risks and benefits associated with wildfires, with implications for predator–prey dynamics in fire‐prone regions.

“Alien versus predator”: predatory effect of coccinellid Exochomus quadripustulatus on the scale insect Toumeyella parvicornis. An open‐field experimentation on the Pinus pinea of Rome

Insect Science, EarlyView.
The release of gravid Exochomus quadripustulatus females proved to be effective in containing Toumeyella parvicornis infestations on stone pine trees, under open‐field condition. The ladybugs caused a lower infestation level compared to the trees that did not receive any ladybugs during the observation season.
