Cryptobia iubilans in Cichlids
EDIS, 2014 After many years of diagnostics at the University of Florida and at other laboratories around the country, it appears that Cryptobia iubilans is not uncommon among cichlids, and that environmental and other factors determine the extent of disease.

Coral reef fish visual adaptations to a changing world
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Coral reef ecosystems show fluctuations in their prevailing light environment in response to both regular (e.g. between seasons) and more prevalent stochastic events (e.g. human‐induced sediment runoff).

On the occurrence of three non-native cichlid species including the first record of a feral population of Pelmatolapia (Tilapia) mariae (Boulenger, 1899) in Europe [PDF]
Royal Society Open Science, 2017 Thermally influenced freshwater systems provide suitable conditions for non-native species of tropical and subtropical origin to survive and form proliferating populations beyond their native ranges.

Integrative Zoology, EarlyView.The urban environment may exert different selective pressures on sexually selected traits than more pristine environments. Our study shows that sexual coloration is more saturated (bluer) in male lizards from urban environments than in male non‐urban lizards. The average parasite load is lower in urban lizards than in non‐urban lizards.

Improving Whole Biodiversity Monitoring and Discovery With Environmental DNA Metagenomics
Molecular Ecology Resources, EarlyView.ABSTRACT Environmental DNA (eDNA) metagenomics sequences all DNA molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels of false positives and negatives, this approach is underexplored as a tool for biodiversity monitoring across the tree of

A novel apparatus for studying fish cognition in the wild
Methods in Ecology and Evolution, EarlyView.Abstract Fish show a huge variation of ecological, anatomical and behavioural traits, which makes them prime subjects for studying behaviour, cognition and their evolution. Lab‐based studies allow a controlled examination of some of the mechanisms underpinning cognition and have yielded many insights into fish cognitive abilities.

Cichlid: Explicit physical memory management for large machines [PDF]
arXiv, 2019 In this paper, we rethink how an OS supports virtual memory. Classical VM is an opaque abstraction of RAM, backed by demand paging. However, most systems today (from phones to data-centers) do not page, and indeed may require the performance benefits of non-paged physical memory, precise NUMA allocation, etc.

Computer simulations on the sympatric speciation modes for the Midas cichlid species complex [PDF]
arXiv, 2007 Cichlid fishes are one of the best model system for the study of evolution of the species. Inspired by them, in this paper we simulated the splitting of a single species into two separate ones via random mutations, with both populations living together in sympatry, sharing the same habitat.

Biology Open, 2019 Information transfer between individuals typically depends on multiple sensory channels. Yet, how multi-sensory inputs shape adaptive behavioural decisions remains largely unexplored.
