Why do some fish fight more than others? [PDF]
, 2012 Reversible changes in how readily animals fight can be explained in terms of adaptive responses to differences in the costs and benefits of fighting. In contrast, long-term differences in aggressiveness raise a number of questions, including why animals ...

Ecohydrology, Volume 19, Issue 1, January‐February 2026.ABSTRACT Benthic macroinvertebrates are indicators of water quality and riparian ecosystem health. Their abundance and distribution in streams are associated with river basin environmental factors, including stream biotic and abiotic fluvial processes. We examined benthic macroinvertebrate diversity and abundance in relation to large wood (LW) and pool‐

Oikos, Volume 2026, Issue 1, January 2026.Demographic resilience refers to the capacity of a population to resist and recover from disturbances in terms of both population size and structure. Resilience to severe disturbance events, such as heatwaves, floods, and cold snaps, is likely to vary with the life‐history characteristics of the population, such as migratory strategy, and demographic ...

River Research and Applications, Volume 42, Issue 1, Page 123-148, January 2026.ABSTRACT Today, salmonid management is largely based on river restoration. One of the fundamental elements is the creation of functional spawning sites. Key values of sedimentological characteristics must be defined in terms of granulometry, permeability, and oxygen concentration to ensure the best possible success of the operations.
