Identifying drivers of tropical riverine larval fish abundance and diversity [PDF]

, 2022
Several hypotheses and conceptual models propose to explain mechanisms mediating riverine fish abundance, but few empirical studies to date have explored their utility in tropical systems.

Food web pathways for fish communities in small tropical streams [PDF]

, 2020
It is often assumed that invertebrate consumers in small tropical streams are dependent on allochthonous sources, although recent studies indicate that algae can form the base of food webs in tropical streams.

Macroalgal meadow habitats support fish and fisheries in diverse tropical seascapes [Elektronisk resurs] [PDF]

, 2020
Canopy-forming macroalgae can construct extensive meadow habitats in tropical seascapes occupied by fishes that span a diversity of taxa, life-history stages and ecological roles.

Local and regional rarity in a diverse tropical fish assemblage [PDF]

, 2012
Because most species in an ecological assemblage are rare, much of the species richness we value is due to taxa with few individuals or a restricted distribution.

Population and Transcriptomic Changes of the Tropical Fish Parasite Caligus confusus (Copepoda: Caligidae) with Seasonal Variations in Sea Temperature [PDF]

, 2023
Fish–parasite systems could be subject to two scenarios under climate change: (i) increased water temperature might enhance parasite metabolism, allowing the parasite to spread rapidly; (ii) parasitism could decrease if the optimal temperature for ...

Implications of differences between temperate and tropical freshwater ecosystems for the ecological risk assessment of pesticides [PDF]

, 2010
Despite considerable increased pesticide use over the past decades, little research has been done into their fate and effects in surface waters in tropical regions.

Reproductive strategies and genetic variability in tropical freshwater fish

Genetics and Molecular Biology, 2007
We estimated the genetic variability of nine fish species from the Brazilian upper Paraná River floodplain (Astyanax altiparanae, Hoplias malabaricus, Leporinus lacustris, Loricariichthys platymetopon, Parauchenipterus galeatus, Pimelodus maculatus ...

Climate change and its implications for Australia's freshwater fish [PDF]

, 2011
Freshwater environments and their fishes are particularly vulnerable to climate change because the persistence and quality of aquatic habitat depend heavily on climatic and hydrologic regimes.

TUBERCULOSIS IN MARINE TROPICAL FISHES IN AN AQUARIUM [PDF]

Journal of Wildlife Diseases, 1980
Skin, gill and visceral tubercle lesions were detected in marine tropical fish in an aquarium. Ninety-seven fish of 17 different genera were affected. The tubercles consisted of a wall of densely packed epithelioid cells and necrotic center packed with acid-fast bacilli identified as Mycobacterium marinum.
