Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

Cladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Ontogenetic diet shifts of Oreochromis niloticus and Tilapia rendalli of the Barra Bonita reservoir (Tietê river, São Paulo State, Brazil)=Mudanças ontogenéticas na dieta de Oreochromis niloticus and Tilapia rendalli da represa de Barra Bonita (rio Tietê, Estado de São Paulo, Brasil) [PDF]

Acta Scientiarum: Biological Sciences, 2012
The Nile Tilapia, Oreochromis niloticus, and the Congo Tilapia, Tilapia rendalli, are important members of the African cichlids, and have been introduced to many Brazilian lakes and reservoirs.

Habitat Choice as a Function of Lighting Environment in Bluefin Killifish

Ethology, EarlyView.
This experiment tested habitat preference in bluefin killifish as a function of lighting environment for fish from a swamp and a spring population. Swamps are red‐shifted habitats and springs are full spectrum. Fish from the swamp population preferred the red‐shifted lighting environment, while spring fish were tolerant of both lighting environments ...

From shallow to deep divergences:mixed messages from Amazon Basin cichlids

, 2019
Cichlids are a conspicuous component of Amazonian ichthyofauna, filling a wide range of niches. Yet taxonomy of many groups is still poorly known in the Amazon, and most of the yet-to-be discovered species are concentrated there.

Predator avoidance in extremophile fish [PDF]

, 2013
Extreme habitats are often characterized by reduced predation pressures, thus representing refuges for the inhabiting species. The present study was designed to investigate predator avoidance of extremophile populations of Poecilia mexicana and P ...

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

Fish and Fisheries, EarlyView.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

Age, growth and sexual dimorphism of the monkeyface prickleback (Cebidichthys violaceus)

Journal of Fish Biology, EarlyView.
Abstract Accurate estimates of age, growth and maturation are fundamental to fisheries assessment, conservation and the development of emerging aquaculture species. However, life‐history parameters can vary within species and may be influenced by factors such as sexual dimorphism, which is often poorly quantified in non‐commercial or understudied ...

The evolution of monogamy in cichlids and marine reef fishes

, 2022
Although several hypotheses have been proposed to explain the emergence of social monogamy, its origin is still intensely debated. Monogamy has many potential drivers, but evolutionary causality among them remains unclear.

The coincidence of ecological opportunity with hybridization explains rapid adaptive radiation in Lake Mweru cichlid fishes

Nature Communications, 2019
Recent studies have suggested that hybridization can facilitate adaptive radiations. Here, the authors show that opportunity for hybridization differentiates Lake Mweru, where cichlids radiated, and Lake Bangweulu, where cichlids did not radiate despite ...
