Persisting at the Edge of Ecological Collapse: The Impact of Urbanization on Fish and Amphibian Communities From Lake Xochimilco

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
ABSTRACT Freshwater ecosystems are globally threatened by habitat loss, pollution, and invasive species, all of which are particularly acute in urban areas. To assess the impacts of urbanization on freshwater biodiversity—specifically the effects of alien species on native primary aquatic vertebrates—we investigated the World Heritage Site, Lake ...

Exploring soil erosion in the lake basins of Michoacán, Mexico: From sediment cores to conservation policies

open access: yesJournal of Quaternary Science, Volume 40, Issue 4, Page 671-683, May 2025.
ABSTRACT Understanding soil erosion, its history and links to potential drivers such as land use (particularly agriculture and deforestation), different cultural perspectives and climate change are crucial for the development of effective management and conservation strategies.

Invisible plastics problem in intensive aquaculture: The case of polyvinylpyrrolidone

open access: yesReviews in Aquaculture, Volume 16, Issue 4, Page 1544-1554, September 2024.
An emerging contaminant of freshwater ecosystems, the water‐soluble synthetic polymer, polyvinylpyrrolidone, is a biodegradation‐resistant pollutant which may be accumulating within aquaculture systems due to its ubiquitous presence in products used as prophylactic and therapeutic agents to culture aquatic species.

Implicaciones de la alimentación continua sobre la demanda de oxígeno en un pez agástrico con intestino corto (Teleostei: Atherinopsidae)

open access: yesEcosistemas y Recursos Agropecuarios
Continuous illumination and increased feeding periods have enhanced growth in commercial fish species. However, oxygen consumption under these conditions has yet to be previously assessed in agastric short-intestine fish. This study evaluated Chirostoma

Effects of dietary hydrolysate supplementation on growth, body composition, hematological responses, and liver histology of juvenile giant trevally (Caranx ignobilis Forsskal, 1775)

open access: yesJournal of Fish Biology, Volume 104, Issue 1, Page 216-226, January 2024.
Abstract A feeding study was conducted to investigate how fish protein hydrolysate (FPH) supplementation affected the growth, feed utilization, body composition, and hematology of juvenile giant trevally (Caranx ignobilis Forsskal, 1775). Seven isonitrogenous (52% protein) and isocaloric diets (10% lipid) were formulated, wherein shrimp hydrolysate (SH)

Ameliorative Effects of Different Dietary Levels of Fish Protein Hydrolysate (FPH) on Growth and Reproductive Performance, Feed Stability, Tissues Biochemical Composition, Haematobiochemical Profile, Liver Histology, and Economic Analysis of Pabda (Ompok pabda) Broodstock

open access: yesAquaculture Research, Volume 2024, Issue 1, 2024.
This study investigated the impacts of various inclusion levels of dietary potential of fish protein hydrolysate (FPH) on the growth and reproductive performance, biochemical composition, blood parameters, and liver histology of Ompok pabda broodstock. About 600 pabda broods (11.00 ± 0.05 g) were distributed into 12 cages and fed twice in a day.
