Suggestions of collapse in small herbivore cycles since the 1980s have raised concerns about loss essential ecosystem functions. Whether such phenomena are general and result from extrinsic environmental changes or intrinsic process stochasticity is currently unknown. Using a large compilation time series vole abundances, we demonstrate consistent cycle amplitude dampening associated with reduction winter population growth, although regulatory processes responsible for cyclicity not been...
Abstract With rapid development and the spread of urbanized land, there is an increasing need to understand species' responses urban conditions. Carnivores are considered be sensitive urbanization; however, ample evidence that some carnivore species successfully inhabit areas, human‐modified habitats have recently been recognized as important refuge for several species. Despite number studies on ecology, no comprehensive cross‐species comparisons made in order assess effects urbanization...
Background White-nose syndrome is a disease of hibernating insectivorous bats associated with the fungus Geomyces destructans. It first appeared in North America 2006, where over million died since then. In Europe, G. destructans was identified France 2009. Its distribution, infection dynamics, and effects on Europe are largely unknown. Methodology/Principal Findings We screened hibernacula Czech Republic Slovakia for presence during winter seasons 2008/2009 2009/2010. 2009/2010, we found...
Abstract Common voles ( Microtus arvalis ) are widespread in the European agricultural landscape from central Spain to Russia. During population outbreaks, significant damage a variety of crops is caused and risk pathogen transmission people increases. In 2019, increasing or unusually high common vole densities have been reported several countries. This highly important terms food production public health. Therefore, authorities, extension services farmers need be aware rapid increase take...
A new geographical gradient in the dynamics of small rodents is demonstrated by analysing 29 time series density indices common vole (Microtus arvalis) from Poland, Czech Republic and Slovak Republic. This extends more stable northerly populations coastal Poland to variable cyclic southernmost parts Republic, hence a reversal Fennoscandian gradient. All studied variables (such as mean density, cycle amplitude, variability coefficients second–order autoregressive model) exhibit consistent...

Abstract We investigated the effect of multiple variables on amplification success rate microsatellite DNA extracted from faeces wild Eurasian otters. The was affected by (i) type sample, with higher rates in anal jelly samples than faeces, and (ii) temperature, a negative increased temperature at time collection. To increase effectiveness genotyping otter we recommend collecting cold months early morning, preferably frozen state, collection samples, or part whenever possible.

Using long-term data on incidences of Lyme disease and tickborne encephalitis, we showed that the dynamics both diseases in central Europe are predictable from rodent host densities climate indices. Our approach offers a simple effective tool to predict risk 1 year advance.
Vole population sex ratio varies seasonally. However, ratios have usually been estimated using naïve estimators that do not allow for biases owing to the difference in capture probabilities and movement distances (i.e., effective areas sampled). Here we aimed advance methodological approach, recognizing there are two different classes of contributing mechanisms pattern which best addressed separately: (1) those mechan isms imposing a systematic error (bias) estimates (2) generating true...
Abstract To evaluate host responses towards repeated brood parasitism we experimentally parasitized and continuously videotaped blackcap nests in two consecutive trials. The ejection of a foreign egg was the most common response (94.5%) both trials, but desertion (4.1%) acceptance (1.4%) also occurred. general method puncturing. In 9.8% identified ejections, already punctured eggs stuck to abdominal feathers incubating bird were carried out nest. Females responsible for majority ejections...
Spatial synchrony of population fluctuations is ubiquitous in nature. Theoretical models suggest that correlated environmental stochasticity, dispersal, and trophic interactions are important promoters nature to leave characteristic signatures distance-dependent decays synchrony. Recent refinements this theory have clarified how distance-decay curves may steepen if local dynamics governed by different density-dependent feedbacks should vary regionally the importance correlation stochasticity...
Summary Using long‐term data sets from two lowland floodplain forest bank vole populations in central Europe, we tested predictions that with increasing densities: (i) proportions of nonparous females winter would increase; and (ii) age both parous increase. These follow the assumption changes structure are driven by density‐dependent shifts at first reproduction. Both were sampled snap trapping between 1956 1976. For each year, examined samples animals collected November April for without...
Abstract The subject of population cycles is regarded as controversial due to a number unsettled questions such whether or not cyclic patterns are governed by the same processes at high and low latitudes in Europe. Recent evidence suggests that dynamics share common temporal pattern vole referred collapsing cycles. Despite concurrent interest, key contention around causal mechanisms drive remains hot topic ecology. aims this study supplement information on seasonal field Microtus agrestis...

This study focuses on the bioconversion of agricultural wastes (AWs) in rural Egypt.We analyzed data derived from literature to implement a future image suiting Egypt's situation.Despite limited information field management Egypt and gap between formal practical data, studies consistently showed that is suitable sustainably treat unused part AWs, which about 52% total 46.7×10 6 tons year -1 .Bioconversion can convert those AWs into 12.6×10 9 m 3 biogas with 60% methane, equal 7.6×10 natural...
