Summary: The stone crayfish Austropotamobius torrentium is globally endangered due to anthropogenic pressure, climate change, and the invasive signal crayfish Pacifastacus leniusculus. The study shows that climate change is likely to result in significant loss of suitable habitats for A. torrentium, putting highly diverse populations at risk of extinction. Furthermore, the threat from climate change appears to be greater for A. torrentium than the invasive crayfish species.

Summary: The study reported a stone crayfish population in a stream in southern lowlands of Romania, belonging to the most widespread phylogroup and sharing the same haplotype with specimens from Croatia. Unfortunately, this population likely disappeared due to crayfish plague, highlighting the vulnerability of isolated relic populations.

Summary: This study developed and validated species-specific assays based on hydrolysis probe chemistry to detect the presence of the stone crayfish and the white-clawed crayfish in water samples. The results confirmed the presence of the stone crayfish at several sites, including some where it was detected for the first time. Additionally, the method successfully detected the presence of the white-clawed crayfish.

Summary: This study aims to assess how habitat alteration and subsequent water quality changes affect the stone crayfish population in the Kustosak Stream (Croatia) through three selected sites under different levels of anthropogenic disturbance. The results showed that habitat alteration caused an overall reduction in population abundance and changes in size structure, however, it had not yet resulted in detectable genetic differences. Crayfish abundance was affected by the physicochemical parameters of water, including oxygen, calcium ions, nitrates, pH, and water temperature.

Summary: This study in six floristic areas of the Czech Republic explores the relationships between orchid species richness, species specialization index and altitude, revealing different trends among orchid groups classified by rooting systems. These patterns are likely influenced by the country's orography and distribution of habitats in the six floristic areas.

Summary: In recent decades, there has been a significant global decline in pollinators, with bumblebees being one of the important contributors to pollination. Factors such as habitat loss, climate change, pesticides, and pathogens have contributed to the decline of bumblebee populations. This study provides the first knowledge of the occurrence of three parasite species in bumblebees in the Czech Republic and reveals the influence of environment on parasite infection.

Summary: The incidence and risk of mosquito-borne disease outbreaks in Northwestern Europe have increased. This study examined the interactive effects of land use, soil type, and climatic conditions on the abundance of mosquitoes. The results showed that mosquito abundance and species richness varied among different land use and soil types, and that rainfall events had a significant impact on mosquito abundance. These findings highlight the importance of considering local environmental factors in studying and mitigating disease risk.

Summary: This study used bird monitoring data from Czech Republic to investigate the land use utilisation and habitat overlap of five Columbidae species. The results showed that these species primarily overlapped in farmlands and urban areas, confirming their habitat affinities. The study provides important insights into the distribution and habitat preferences of these common species.

Summary: Climate change and human activities pose a major threat to forest resources and livelihoods. Understanding the factors influencing the distribution and abundance of priority species is crucial for conservation. In this study, we investigated the factors affecting the distribution and abundance of Rici-nodendron heudelotii in Benin and assessed its population structure. Our results showed that the species is mainly distributed in highly watered areas with annual rainfall between 900 mm and 1300 mm. The abundance of the species varied between different areas and was significantly influenced by aridity index, moisture index, harvest intensity, and wildfires. Assessment of population structure revealed a predominance of small-diameter individuals, indicating population stability. Successful conservation of the species requires addressing anthropogenic pressures.

Summary: This study assessed the genetic variation levels and patterns of freshwater crayfish populations in the Iberian Peninsula, revealing high genetic diversity significantly structured into three main genetic groups. The findings suggest the importance of considering these three phylogeographic groups as essential management units for the conservation of the species' remaining genetic diversity.

Summary: Oilseed rape is often damaged by insect pests, particularly Brassicogethes aeneus, which is one of the most significant pests of spring and winter oilseed rape. Different pollen beetle species were monitored in the Czech Republic from 2011 to 2013. The species were identified based on morphometric characteristics and the morphology of male and/or female genitalia. The presence of these beetles in oilseed rape is likely due to the availability of pollen as their food source, and they may also be transported by air over long distances. Accompanying pollen beetle species may have a beneficial effect on reducing the abundance of harmful species by acting as hosts to parasitoids of the oilseed rape pest.

Summary: The distribution of mercury species was studied in the Zaskalska water reservoir near an abandoned cinnabar mine in Czech Republic. The results showed that the mercury from the mine is the major source of mercury in the reservoir. The legal maximum limit for mercury concentration was exceeded during rainy periods, and the dominant form of mercury in sediments was mercury sulphide. The mercury content in fish muscle exceeded the legal limit, posing a health risk. The study highlights the need for legal restrictions on the consumption of piscivorous fish caught downstream of abandoned cinnabar mines.

Summary: This study characterizes the spring distribution of pteropods in the Mediterranean Sea and investigates their ecological preferences. The results show that pteropod abundance is higher in the Eastern Mediterranean Sea compared to the Western basin. Environmental factors such as temperature, oxygen concentration, salinity, and aragonite saturation significantly affect the community structure of pteropods.

Summary: Transformation of food systems is necessary for feeding the growing global population. The rice-crayfish integrative system (RCIS) allows for the production of multiple types of food on the same land area and has gained popularity in Asian countries. However, there is limited information regarding the distribution of crayfish in paddy fields, which is crucial for effective management. This study conducted a 2-year field experiment and found that crayfish distribution in RCIS is influenced by water depth and field topography, with the highest densities observed in gullies near the short ridge of rectangular farmland.
