Summary: The study investigates the distribution of the rusty crayfish in North America, revealing confusion and overlap in the native and introduced ranges of this species, which has implications for conservation efforts. This review highlights the lack of clear understanding of essential concepts such as native and non-native range even for intensely studied invasive species.

Summary: The study tested a harvest removal strategy for invasive Rusty Crayfish in Lake Michigan. Results showed a statistically significant reduction in Rusty Crayfish densities at one reef, with sustained reductions over the egg maturation period for native fish. The study highlights the importance of considering density-dependent population responses in invasive species management and raises questions about the efficacy of adult-only crayfish removal strategies.

Summary: Monitoring of rusty crayfish populations in Lake Michigan revealed size-class segregation and variations in distribution and abundance on spawning reefs in response to different environmental conditions. The study also compared seasonal trends and inferred novel life-history responses from rusty crayfish in the unique habitat of Lake Michigan.

Summary: This study explores the effects of clothianidin on the behavioral ecology of rusty crayfish. The results show that clothianidin exposure affects the locomotion, chemosensory response, and agonistic encounters of crayfish. The exposed crayfish spent more time interacting and showed chemosensory dysfunction, which impaired their ability to recognize previous competitors.

Summary: The study analyzed the population structure and predicted the range expansion of signal crayfish in Northwestern Italy. Results suggest that the species may completely invade the Erro Stream network in 30-40 years, without additional introductions, highlighting the importance of preventing the spread of invasive species.

Summary: The marbled crayfish is a recently discovered freshwater crayfish species that reproduces through apomictic parthenogenesis, resulting in a monoclonal, all-female population. Despite being known for their invasive mode of reproduction, they are not more invasive than other cultured crayfish species. Their resiliency and adaptability make them suitable for closed, environmentally safe aquaculture approaches, with potential for sustainable production.

Summary: High densities of invasive rusty crayfish on critical spawning reefs may hinder the recovery of native fish in the Laurentian Great Lakes, but standard Gee minnow traps remain a sensible choice for monitoring and potential suppression efforts. However, modifications to trap design are needed to improve capture efficiency and retention.

Summary: Neogobius melanostomus, an invasive fish species, poses a potential threat to crayfish and A. aquaticus populations in river tributaries, potentially causing disruptions to the macrozoobenthic community and triggering trophic cascades. Its non-selective feeding behavior may have significant ecological impacts on the ecosystem.

Summary: Driftwood in river catchments can pose safety hazards for infrastructures like dams, but can be valorized for biochar production. This study provides a comprehensive analysis of different physico-chemical properties of river driftwood, indicating potential for utilization as feedstock for biochar production regardless of genera or type.

Summary: The Penobscot River Restoration Project in Maine removed two lowermost dams and improved fish passage to rehabilitate the river. Fish assemblages were surveyed for 3 years prior to and after rehabilitation, revealing significant changes with increased prevalence of riverine and migratory species after dam removal. Long-term sampling also showed increased abundance of alosine fish in tributaries and tidally influenced areas, while lacustrine species still dominate upstream of the lowermost dam. This study provides evidence that dam removals result in altered fish assemblages dominated by riverine and anadromous species in previously impounded habitats.

Summary: Restoring river habitat heterogeneity is valuable yet often ineffective for aquatic biota. Short-term studies fail to consider natural fluctuations and changing effects of restoration, emphasizing the need for long-term research. A case study on the Nidda River in Germany highlights the limited impact of restoration efforts on macroinvertebrate, macrophyte, and fish communities over a 10-year period. Combining local- with broad-scale restoration and addressing primary drivers may be crucial for successful river restorations.

Summary: The study found that most MPAs did not significantly impact the increase in size and abundance of reef fish in the SWMPA, but reef species with formal stock assessments increased in the SWMPA. The mean length of red porgy significantly increased in the SWMPA.

Summary: This study explores the relationship between landscape fragmentation and ecosystem service value (ESV), finding a negative correlation between ESV and landscape fragmentation. By utilizing remote sensing imagery and analytical methods, different landscape parts were identified and ESV was calculated for different areas. The study also reveals a decrease in ESV in specific areas due to vegetation and water degradation caused by fragmentation.

Summary: The aquarium pet trade is a source of potentially invasive crayfish species that can be introduced into new environments, posing a threat to native biodiversity and freshwater ecosystem functioning. Europe, particularly Serbia, is experiencing an increase in invasive crayfish species, such as the marbled crayfish and the red swamp crayfish, traded as ornamentals. The presence of these species in the pet trade could lead to their occurrence in the wild.

Summary: The expansion of woody plants is altering ecosystem structures globally, impacting fire regimes. Tree-reduction treatments are implemented to reduce fuel loads, increase ecological resilience, and improve habitat, but few studies examine long-term outcomes. The Sagebrush Treatment Evaluation Project (SageSTEP) evaluated the effects of prescribed fire and cut-and-leave treatments on sagebrush communities, showing that treatment outcomes are influenced by tree dominance, soil climate, and time since treatment.
