Feeding Behaviour of Eurasian Beavers (Castor fiber) Along Small Streams in an Agricultural Landscape

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2022
In areas with high population density, the Eurasian beaver may be forced to utilise sparsely forested landscapes where living conditions may not be optimal for the species. Here, we examine the feeding strategy of Eurasian beavers along a number of small

What season suits you best? Seasonal light changes and cyanobacterial competition [PDF]

open access: yes, 2015
Nearly all living organisms, including some bacterial species, exhibit biological processes with a period of about 24 h called circadian (from the Latin circa, about and dies, day) rhythms.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Influence of diet on the morphology of the ruminal papillae in reindeer calves (Rangifer tarandus tarandus L.)

open access: yesRangifer, 1996
The influence of diet on the morphology of reindeer ruminal papillae was investigated in 4 groups of 3 free-ranging reindeer calves at different seasons, and in 11 groups of 3 reindeer calves fed experimental diets.

Seasonal changes in N-cycling functional genes in sediments and their influencing factors in a typical eutrophic shallow lake, China

open access: yesFrontiers in Microbiology
N-cycling processes mediated by microorganisms are directly linked to the eutrophication of lakes and ecosystem health. Exploring the variation and influencing factors of N-cycling-related genes is of great significance for controlling the eutrophication
