Opis:
Fire is a disturbance that influences global ecosystem structure and function. It is also widely used as a management tool to achieve conservation goals. Wildfires can have highly destructive effects on habitats and their biota. Non-volant animals, such as small mammals, are among the most vulnerable to fire. To date, little is known about the reaction of these animals to fire events in fire-adepted, fast-recovering habitats. Here, we present a systematic literature review to analyse and evaluate the impact of fire on small mammals in open habitats. Most studies were carried out in the New World (Australia, North and South America) in fire-prone habitats. Most of them (74%) focused on forests, and only a quarter (26%) were conducted in habitats with herbaceous vegetation. These 15 articles formed the basis for analysing the response of small mammals living in open areas to fire disturbance. Surprisingly, the effects of fire were of short duration (less than one year) in most studies, and the regeneration of small mammal communities was related to the rate of regeneration of vegetation cover and habitat structure. A crucial factor was fire intensity; the highest diversity of small mammals was associated with low-intensity fires, that resulted in unburned habitat patches (so-called microrefugia). In open areas such as pastures, prairies and meadows, small mammals can survive fires in shelters such as burrows. This systematic review demonstrates that there is a continued focus almost exclusively on fire-prone habitats, whereas due to global change, fire disturbances will be more common and severe in "fire naive" ecosystems in boreal and temperate zones. Significant gaps in the understanding of the recovery ecology of small mammals in open habitats after fires have been identified. Future research should focus on how individual traits of small mammals affect their settling success in burnt

Opis:
Ungulates, primarily cervids, are keystone species as they play a crucial role in the forest ecosystem functioning. In commercial forests, hunting is the most intuitive and straightforward solution to regulate ungulate population density; managing large herbivores in protected areas is much more complicated. On the one hand, deer pressure on vegetation is a part of the natural processes shaping these ecosystems. On the other hand, however, when at high densities, deer can alter natural plant succession trajectories and generate conflicts in nature conservation. Nevertheless, information on population density or trends of these mammals is necessary to predict the potential role of ungulates in forest ecosystems and manage herbivore population densities. Unfortunately, most often, the managers of protected areas do not know the current population status of the large mammals living there. Furthermore, it could be impossible to analyse the large herbivore population trends based on historical inventory data collected using different methods with unknown accuracy. Here we discuss the advantages and disadvantages of three most commonly used inventory methods for large mammals in Poland, such as snow tracking, driving censuses, and pellet group counting. Conclusions on the reliability of the three methods were drawn based on the results of ungulate inventories in the Roztocze National Park, Poland. Snow tracking generates an error of unknown magnitude; therefore, historical data estimated by this method should be cautiously approached. Additionally, with this method, only coefficients are obtained, based on which it is impossible to estimate the population size. The pellet group counting is the least variable method regarding errors; it is cheap and logistically straightforward. Moreover, it also allows the analysis of winter habitat preferences of ungulates. It is therefore recommended as a method for estimating deer and wild boar abundance in many countries worldwide. In summary, long-term trends in abundance are most important for analysing and managing large mammal populations. Therefore, it is necessary to carry out inventories over several years, for which, due to the minor estimation errors and simple logistics, the pellet group counting method seems best.

Opis:
Masting, the highly variable production of synchronized large seed crops, is a common reproductive strategy in plant populations. In wind-pollinated trees, flowering and pollination dynamics are hypothesized to provide the mechanistic link for the well-known relationship between weather and population-level seed production. Several hypotheses make predictions about the effect of weather on annual pollination success. The pollen coupling hypothesis predicts that weather and plant resources drive the flowering effort of trees which directly translates into the size of seed crops through efficient pollination. In contrast, the pollination Moran effect hypothesis predicts that weather affects pollination efficiency, leading to occasional bumper crops. Furthermore, the recently formulated phenology synchrony hypothesis predicts that Moran effects can arise because of weather effects on flowering synchrony, which, in turn, drives pollination efficiency. We investigated the relationship between weather, airborne pollen, and seed production in common European trees, two oak species (Quercus petraea and Q. robur) and beech (Fagus sylvatica) with a 19-year data set from three sites in Poland. Our results show that warm summers preceding flowering correlated with high pollen abundance and warm springs resulted in short pollen seasons (i.e. high flowering synchrony) for all three species. Pollen abundance was the best predictor for seed crops in beech, as predicted under pollen coupling. In oaks, short pollen seasons, rather than pollen abundance, correlated with large seed crops, providing support for the pollination Moran effect and phenology synchrony hypotheses. Fundamentally different mechanisms may therefore drive masting in species of the family Fagacae.
