Snow is an important driver of ecosystem processes in cold biomes. accumulation determines ground temperature, light conditions, and moisture availability during winter. It also affects the growing season’s start end, plant access to nutrients. Here, we review current knowledge snow cover’s role for vegetation, plant-animal interactions, permafrost microbial processes, biogeochemical cycling. We compare studies natural gradients with experimental manipulation assess time scale difference...
Widespread use of neonicotinoid insecticides, such as imidacloprid, is often associated with diminishing populations bees; this loss pollinators presents a concern for food security and may cause unpredictable changes in ecological networks. However, little known about the potential behavioural mechanisms behind neonicotinoid-associated pollinator decline. We quantified effects low-dose (1 ppb) imidacloprid exposure on foraging behaviour bumblebees (Bombus terrestris). Individual were...
Abstract. Climate change is expected to impact the methane budget of boreal peatlands, highlighting need understand factors that influence cycling, including plant community structure. In northern majority transported through plants, and magnitude this process strongly linked composition. Therefore, detailed information about role plants regulating year-round fluxes highly valuable. This paper explores causes spatial variability in plot-scale a rich fen. Methane were measured using manual...
Human observations during behavioral studies are expensive, time-consuming, and error prone. For this reason, automatization of experiments is highly desirable, as it reduces the risk human errors workload. The robotic system we developed simple cheap to build handles feeding data collection automatically. was built using mostly off-the-shelf components has a novel mechanism that uses servos perform refill operations. We used in two separate with bumblebees (Bombus terrestris): both for...
Food deception as a pollination strategy has inspired many studies over the last few decades. Pollinator evolved in orchids possibly to enhance outcrossing. Food-deceptive usually have low pollinator visitation rates compared rewarding species. They may benefit visitations from presence (magnet-species hypothesis) or, alternatively, absence of coflowering species (competition hypothesis). We present data on deceptive, terrestrial orchid Calypso bulbosa , with single flower per plant and...
Abstract Many pollinating animals visit a variety of flowering plant species. Rare species pollinated by such generalists may experience low quality or quantity pollination, depending on the pollinators’ foraging behaviour. How plants cope with this rarity disadvantage is not well understood. One possibility would be to offer higher floral reward, for example, nectar sugar concentration. However, since production costly, rare only able increase their concentration limited time and little...
