Reproductive consequences of mate retention and divorce in a short‐lived migratory passerine

Ibis, EarlyView.
In socially monogamous birds, pair‐bond duration varies across species, from single‐breeding associations to long‐lasting, multi‐year bonds. Studies of pair retention and divorce have focused on long‐lived and sedentary species rather than short‐lived and migratory species.

Basic density and crown parameters of forest forming species within Steppe zone in Ukraine

Folia Oecologica, 2018
The parameters of wood density (WD), bark density (BD) and tree crown characteristics are not only important for estimation of the aboveground biomass, but they also serve as indicators for the timber quality. This study had two objectives: Black locust (

Winners and losers in subarctic moth communities in a changing climate: Marine regime shifts as predictors for terrestrial insect biomass

Insect Conservation and Diversity, EarlyView.
1972–2017, the total moth biomass ina subarctic community had a positive trend but biomass trends differ betweenmoth groups based on taxonomy, phenology and resource use. In the northern latitudes,outbreaking species impact greatly moth biomass Moth biomass is associated withtemperature variables and marine Regime shifts, which can be effective ...

Climate Sensitivity and Drought Legacy of Tree Growth in Plantation Forests in Northeast China Are Species- and Age-Dependent

Remote Sensing
The occurrence, frequency, and severity of drought are accelerating due to global warming. Understanding the vulnerability of plantation forests to climate change, particularly to drought events, is critical to revealing the underlying mechanisms of tree

Temporal and Spatial Change in Diameter Growth of Boreal Scots Pine, Norway Spruce, and Birch under Recent-Generation (CMIP5) Global Climate Model Projections for the 21st Century

, 2018
We investigated how climate change affects the diameter growth of boreal Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies (L.) H. Karst.), and silver birch (Betula pendula Roth) at varying temporal and spatial scales. We generated data with a
