Changes in population characteristics and structure of the signal crayfish at the edge of its invasive range in a European river
The recorded differences in population structure and male morphometry along the invasion pathway could lead to important clues about dynamics of range expansion and population establishment, highlighting the traits that promote dispersal and better response to local conditions in new habitats.
Differences in aggressive behaviour along the expanding range of an invasive crayfish: an important component of invasion dynamics
The observed difference in aggression along the invasion pathway demonstrates that traits that help individuals to overcome challenges of their environment, such as competition against conspecifics, can drive the invasion dynamics of a successful invader in a new environment in terms of both niche competition and intrinsic expansion dynamics.

- 1 September 2012
Long-term trends of hydrological and temperature conditions, prior to closure of new large dam, in five connected karst rivers of central Croatia are analyzed, revealing significant positive trends in average annual temperature at three gauging stations on three rivers with increase of 0.44 and 0.48°C per decade and climate change as the primary cause.
The role of aggression in range expansion and biological invasions
The role of aggression in range expansion of in- vasive species, and its potential role as a driver of range expansion are reviewed, and how these different mechanisms could affect trait variation in expanding and invasive populations are analyzed.

Recent changes in distribution pattern of freshwater crayfish in Croatia − threats and perspectives
Analysis of Croatian freshwater crayfish populations, aiming to gather new distributional data and complement previous surveys (2005–2011), was performed during 2014–2016, within the frame of Natura…
