March 2024 issue of Aquatic Invasions is now online!
This new issue of Aquatic Invasions includes eight research articles that report the presence and distribution of aquatic invasive species, showcasing diverse methods and findings.

The adaptability of Chthamalus challengeri in China's Zhoushan sea area is explored, revealing its ability to survive and thrive across various temperatures and salinities. The research offers insights into the species' survival, growth, and settlement patterns, suggesting its potential for widespread invasion due to its robust adaptability to environmental conditions.

The successful colonization of the Red Sea Yellowspotted Puffer, Torquigener flavimaculosus, in the Mediterranean without a genetic bottleneck is examined. Genetic analysis indicates comparable genetic variability between the migrant and source populations, highlighting the species' successful colonization without the expected genetic bottleneck effects.

An investigation into the ecological impacts of Pontederia crassipes on Jeju Island focuses on its ability to alter water pH and affect native plant growth, coupled with its overwintering capabilities facilitated by climate change. The study emphasizes the need for vigilant management strategies to mitigate the invasive species' environmental threats.

The spread of the invasive Chinese pond mussel, Sinanodonta woodiana, across Europe is studied using occurrence data, climate, and environmental variables. Modelling predicts its potential spread, underscoring the necessity for proactive conservation strategies to manage its invasion across the continent.

A study challenges the predictive accuracy of climate match for non-native freshwater fish introductions in Florida, revealing that climate match does not reliably predict establishment success. The findings highlight the limitations of climate matching tools and suggest the exploration of more complex models to better predict invasion outcomes.

The trophic positions and niche overlaps among native and invasive fish species in a Dutch lowland brook are analyzed, demonstrating significant dietary overlap and potential competition. The study underscores the ecological roles of invasive species and the importance of niche differentiation for coexistence.

Research on the growth of silver carp (Hypophthalmichthys molitrix) in Missouri River tributaries indicates a slowdown in growth rates as the population transitions from introduction to establishment stages. This aligns with expectations of decreased growth rates as populations stabilize, calling for further investigation into the ecological impacts of silver carp establishment.

The invasion of Pterygoplichthys spp. in Bangladesh is detailed, highlighting its widespread presence and the ecological and socio-economic threats posed. Climate match analysis predicts further spread, emphasizing the need for monitoring, public awareness, and government intervention to manage the invasion effectively.
