Embryogenesis and early larval development in bocachico (Prochilodus magdalenae) in Colombia
Journal of Basic and Applied Zoology, 2022 Background The bocachico (Prochilodus magdalenae) is a migratory freshwater fish and one of the main species of Colombian continental fishery. Interest in it is due to the fish’s excellent reproductive characteristics and sociocultural value in its ...

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

People and Nature, Volume 8, Issue 3, Page 782-796, March 2026.Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Total Suspended Solids (TSS) significantly degrade water quality by reducing light penetration and oxygen availability, while facilitating the transport of toxic contaminants. Managing TSS in watersheds requires an understanding of both hydrological connectivity and pollutant dynamics; however, these efforts are significantly constrained by ...

Aquaculture Research, Volume 2025, Issue 1, 2025.Milt cryopreservation facilitates native fish’s constant production of commercial interest. However, it can damage spermatozoa (sptz) due to the osmotic stress of diluents and low temperatures. This study compares spermatic quality in fresh (SF) and cryopreserved (CS) milt in B. amazonicus for 24 h, 1 month, and 3 months.

Reviews in Aquaculture, Volume 16, Issue 4, Page 1981-1995, September 2024.Abstract A healthy skeletal system is fundamental to fish welfare and performance and a key physiological feature of a robust fish. The presence of skeletal deformities in farmed salmonids is a persistent welfare problem in aquaculture, and one which threatens to impede industry growth.
