Causes and consequences of recent degradation of the Magdalena River basin, Colombia

Limnology and Oceanography Letters, Volume 7, Issue 6, Page 451-465, December 2022., 2022
Abstract The Magdalena River in Colombia is one of the world's largest (discharge = 7100 m3 s−1) tropical rivers, hosting > 170 aquatic vertebrate species. However, concise synthesis of the current ecological and environmental status is lacking. By documenting the anthropogenic stressors impacting the river on time scales ranging from centuries to ...

Ultra‐acute exposure to cadmium does not impair whitefish sperm motility

Journal of Fish Biology, Volume 99, Issue 3, Page 1130-1134, September 2021., 2021
Abstract Cadmium (Cd) exposure can impair the traits of aquatic animals associated with reproduction. In natural lakes Cd is typically detected at concentrations below 0.001 mg l−1. The authors investigated the impact of ultra‐acute Cd exposure on sperm motility in European whitefish (Coregonus lavaretus).

Border Collision Bifurcations in a Generalized Model of Population Dynamics

Discrete Dynamics in Nature and Society, Volume 2016, Issue 1, 2016., 2016
We analyze the dynamics of a generalized discrete time population model of a two‐stage species with recruitment and capture. This generalization, which is inspired by other approaches and real data that one can find in literature, consists in considering no restriction for the value of the two key parameters appearing in the model, that is, the natural

Ecological Factors and Diversification among Neotropical Characiforms

International Journal of Ecology, Volume 2012, Issue 1, 2012., 2012
Morphological and DNA sequence data has been used to propose hypotheses of relationships within the Characiformes with minimal comparative discussion of causes underpinning the major intraordinal diversification patterns. We explore potential primary morphological factors controlling the early diversification process in some Neotropical characiforms as
