The silver fir (Abies alba Mill.) is among the most valuable conifers in Europe for ecological and economic reasons. Throughout the course of history, primarily in the 20th century, its share in stands has been declining due to ill-suited management practices, especially clear-cut management, air pollution (SO₂ and NO_X emissions), and wildlife-induced damage. This literature review compiles findings from 338 scientific papers. It describes futures for silver fir and its distribution, ecological requirements, threats and diseases, seed production and nurseries, and forest management practices with emphasis on ongoing climate change. Based on recent knowledge of fir ecology and population dynamics, small-scale shelterwood and selection management have been introduced in fir stands, which have also stabilized them. Fir is an essential species for maintaining high stability and biodiversity, especially on planosols and in waterlogged habitats. Owing to its shade tolerance and environmental plasticity, it can coexist very well with many tree species in mixtures, which can increase the productive potential of stands within the natural range in Europe. The average stand volume of mature fir stands ranges from 237–657 m³ ha⁻¹. For its successful natural regeneration, it is essential to reduce cloven-hoofed game and thus prevent bud browsing damage. The attractiveness of fir in terms of heavy browsing is the highest of all conifers (52% damage). On the other hand, fir is a species relatively resistant to bark stripping and the spread of secondary rot compared with Norway spruce (Picea abies [L.] Karst.). Under global climate change, fir is expected to shift to higher elevations with sufficient precipitation, while in the southern part of its natural range or at lower elevations, outside water-influenced habitats, it is likely to decline. Climate change is intricately linked to the heightened prevalence of forest pathogens with significant damage potential in Europe, necessitating careful consideration and strategic adaptation within management practices of fir forests.

The long-term decline of the black grouse population throughout Europe is influenced by many factors that affect populations differently depending on the distribution range, from Central Europe to the Scandinavian countries. Therefore, we analyzed available literature sources to describe the main reasons for the population decline of this species and to suggest conservation measures. In total, 228 pieces of literature from 1955 to 2024 were analyzed for this study. Based on the literature analysis, it is clear that the drivers of population decline differ across the distributional range. In Central Europe, where the population is declining rapidly, habitat loss and forest fragmentation are crucial factors, as is the negative impact of tourism. In Scandinavia, where the population is gradually declining, decreasing breeding success and increasing chick mortality rates are generally considered the main negative factors. However, these factors also affect black grouse populations in Central Europe. It is crucial to acknowledge that a significant proportion of the contributing factors, such as predation and habitat loss, can be attributed to human activities. Therefore, it is necessary to emphasize that environmental protection should work hand in hand with wildlife managers to improve the situation.

Wild boars are an opportunistic wildlife species that has successfully colonized the human-modified landscape in Europe. However, the current population boom has negative consequences, which result in a rapid increase in human–wildlife conflicts and disease transmission, including African swine fever (ASF). The increasing frequency of conflicts requires adequate solutions for these issues through various measures. Application of deterrents is a common non-lethal measure whose effects have been insufficiently verified until recently. Thus, this study aims to evaluate the effectiveness of odor fences, often applied as a barrier against wild boar movement. For this purpose, 18 wild boars were marked with GPS collars. After 22 days of initial monitoring, 12 sections of odor fences were installed on their home ranges. The monitored wild boars crossed the area 20.5 ± 9.2 times during the pre-installation period and 19.9 ± 8.4 times after the odor fence installation. Moreover, the average home range varied between 377.9 ± 185.0 ha before and 378.1 ± 142.2 ha after the odor fence installation. Based on GPS telemetry results, we do not support using odor repellent lines for crop protection or for limiting wild boar movement to lessen ASF outbreaks.

La infección por Leucocytozoon no influye en la supervivencia de los polluelos de mochuelo boreal Aegolius funereus. Se ha observado que la infección por Leucocytozoon afecta la ecología y fisiología reproductiva de las aves hospedadoras, pero su influencia en la supervivencia de los polluelos aún no está completamente determinada. Se investigó el efecto de la intensidad de la infección por Leucocytozoon, determinada mediante análisis de muestras de PCR por triplicado, sobre la supervivencia de 256 polluelos de mochuelo boreal (Aegolius funereus) durante un estudio de ocho años. Contrariamente a nuestras expectativas, la probabilidad de supervivencia de los polluelos de mochuelo boreal no se vio influenciada por la intensidad de la infección por Leucocytozoon. La edad de los polluelos y la intensidad de la infección por Leucocytozoon en los padres machos y hembras tampoco afectaron la supervivencia de los polluelos. En cambio, la abundancia de alimento y el orden de eclosión fueron los principales factores que influyeron en la supervivencia de los polluelos. Además, se observó una intensidad de infección por Leucocytozoon significativamente mayor en los padres machos en comparación con las hembras y los polluelos. Se sugiere que una clara división de los roles parentales puede llevar a que las hembras y los polluelos que permanecen dentro de las cajas nido (cavidades) experimenten una menor exposición a vectores potenciales que transmitan parásitos sanguíneos en comparación con los individuos adultos masculinos. Nuestro estudio muestra que la enfermedad de Leucocytozoon puede no ser letal para los polluelos de mochuelo boreal, ya que exhiben una intensidad de infección por debajo del promedio en comparación con sus padres machos.

The European hare (Lepus europaeus) is one of the farmland specialists inhabiting agroecosystems. It is particularly sensitive to negative changes in agricultural management and landscape homogenization. The quality of the environment affects not only the hare population dynamics but also the behaviour of individuals, which is reflected in the variation in home range sizes. Preliminary results of the GPS telemetry monitoring in the Czech Republic revealed significant differences in the home range size of hares in high-diversified farmland (18.62 ± 4.14 ha) and conventionally managed agroecosystems (129.96 ± 55.64 ha) during the spring. These results demonstrate that the hare can thrive in a relatively small area, provided there are sufficient food sources and suitable shelter opportunities. However, increasing the biodiversity of the landscape can benefit not only the European hare but also other wildlife including protected birds and animals, which can respond to positive changes in the agroecosystem.
