Flight plays a central role in the life histories of birds but is extremely energy demanding. Reproduction is also associated with high energy demands. We might thus expect to see differences in movement behaviour between individuals that breed successfully, those that breed unsuccessfully, and those that do not breed, assuming that individuals adapt ...

Is Nocturnal Pollination Important for Crop Production? Experimental Evidence From Small Fruit Crops
ABSTRACT Insect‐mediated pollination is essential for crop production but is mainly studied considering diurnal pollinators only. Here, we use pollinator exclusion techniques to prevent either diurnal or nocturnal insect visits in small fruit crops: raspberry (Rubus idaeus), over 1 year, and red currant (Ribes rubrum) and black currant (Ribes nigrum ...

The influence of environmental conditions on the selection of spring migration routes by caribou
Abstract Animal migrations influence key ecological processes such as predator–prey dynamics, nutrient and energy cycling, and community structure. Long‐distance migrations are declining worldwide, and a better understanding of the factors influencing animal space use during migrations is essential to maintain this behavior in the wild.

Spruce Budworm Defoliation Influences Greenhouse Gas Concentrations in Streams
Abstract One of the most significant natural disturbances in the Canadian boreal and hemiboreal forest is tree defoliation by eastern spruce budworm (SBW), which may increase nutrient and carbon inputs to catchment soils, and in runoff. Closely connected to catchments, headwater streams are known to be significant emitters of greenhouse gases (GHGs ...

Protected Areas and Agricultural Biodiversity Conservation—Do Parks Increase AES Adoption?
ABSTRACT Although both protected areas and agri‐environment schemes (AES) aim to conserve biodiversity, the interaction between the two policy instruments is unknown. We investigate the effects of listing a region as a protected area (a regional nature park) on the uptake of biodiversity conservation AES within the region. Using panel data of all Swiss

Plant conservation in a changing Mediterranean world
The Mediterranean is one of five climatic regions on the planet characterised by a prolonged summer drought, exceptional plant diversity and high rates of endemism. We provide a framework to link the ecology of plant species conservation in the context of rapid and extreme climate deregulation to a philosophical typology of temporal attitudes (i.e ...
