Characterization of the imaginal reproductive diapause of Oebalus poecilus (Dallas) (Hemiptera: Pentatomidae)

Brazilian Journal of Biology
The state of development of the internal reproductive organs of male and female Oebalus poecilus (Dallas) as well as the body fat amount in the abdominal cavity during hibernation, of individuals sampled in bamboo litter in Eldorado do Sul (30º02'S and ...

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Plasma insulin‐like growth‐factor 1 (IGF‐1) concentrations predict early life‐history traits in a wild mammal

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The hormone insulin‐like growth factor 1 (IGF‐1) is a key player in the insulin/IGF signalling (IIS) pathway. Extensive biogerontological research demonstrates that this evolutionarily conserved nutrient‐sensing pathway plays a causal role in the regulation of growth ...

Juvenile predation overwhelms nutritional effects on female ungulate fat reserves in a high‐predation system

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ungulate body fat reserves reflect the nutritional environment, often serving as a useful indicator of bottom‐up resource availability. However, body fat reserves also integrate energetic costs associated with avoiding predation risk and reproductive effort, and it is ...

Marketable yield quantity and quality of leek and residual soil mineral nitrogen in relation to nitrogen fertilization

, 2019
In Flanders threshold values of soil mineral nitrogen (Nmin) in the soil profile (0-90 cm) in autumn are used in legislation to judge fertilization practices and evaluate the nitrate (NO3-) leaching risk during winter.

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.

Multilocus sequence typing of the invasive pest Halyomorpha halys (Hemiptera: Pentatomidae) and associated endosymbiont reveals unexplored diversity

Insect Science, EarlyView.
A multilocus sequence typing approach is proposed to explore Halymorpha halys genetic diversity, taking into consideration both insect nuclear markers and markers from the gut symbiont “Candidatus Pantoa carbekii.” Increased information was revealed regarding the number of distinct holobiont haplotypes in native and invasive populations of the pest ...

Protection of Overwintering Aphid Parasitoid, Lysiphlebia japonica [Hym.: Aphidiidae] [PDF]

, 1991
Tonghua County is located in the Changbaishan mountain area where there are about 130 days yearly with average temperature below 0ºC and the lowest temperature can reach - 35ºC. To understand the natural survival of overwintering Lysiphlebia japonica, we

“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.
