Journal of Biogeography, EarlyView.ABSTRACT Aim The role of historical drainage connectivity and the influence of water level fluctuations in African lakes on the evolution and distribution of macroinvertebrates remain poorly understood. This is partly because evolutionary biology research has largely focused on mobile vertebrates, such as cichlids.

RORS: Enhanced Rule-based OWL Reasoning on Spark
, 2016 The rule-based OWL reasoning is to compute the deductive closure of an ontology by applying RDF/RDFS and OWL entailment rules. The performance of the rule-based OWL reasoning is often sensitive to the rule execution order.

Ecophenotypic Variation of Midas Cichlid, Amphilophus citrinellus (Gunther, 1864), in Lake Batur, Bali, Indonesia [PDF]
Brazilian Journal of BiologyCichlid fishes exhibit rapid adaptive radiations with significant diversification rates in response to ecological variability, i.e., ecological opportunity or geographical isolation.

Hybrid Breakdown in Cichlid Fish
PLOS ONE, 2015 Studies from a wide diversity of taxa have shown a negative relationship between genetic compatibility and the divergence time of hybridizing genomes. Theory predicts the main breakdown of fitness to happen after the F1 hybrid generation, when heterosis subsides and recessive allelic (Dobzhansky-Muller) incompatibilities are increasingly unmasked.

Journal of Biogeography, EarlyView.ABSTRACT Aim Southern Africa harbours a diverse array of dung beetles (Scarabaeidae: Scarabaeinae), with many species endemic to the region. Despite this diversity, the historical drivers of their evolution remain largely unexplored. This study investigates the evolutionary history of the flightless dung beetle genus Macroderes, testing its monophyly ...

Selectivity in regeneration of the oculomotor nerve in the cichlid fish, Astronotus ocellatus [PDF]
, 1965 It has long been considered a general rule for nerve regeneration that the reinnervation of skeletal muscle is nonselective. Regenerating nerve fibers are supposed to reconnect with one skeletal muscle as readily as another according to studies covering ...

Island time and the interplay between ecology and evolution in species diversification. [PDF]
, 2015 Research on the dynamics of biodiversity has progressed tremendously over recent years, although in two separate directions - ecological, to determine change over space at a given time, and evolutionary, to understand change over time.

Sex group composition, social interaction, and metabolism in the fish Nile tilapia
Brazilian Journal of BiologyWe tested whether the fish Nile tilapia (Oreochromis niloticus) in a monosex male group spends more energy and displays an agonistic profile, differently from males in male-female groups.

Journal of Fish Biology, Volume 107, Issue 5, Page 1519-1531, November 2025.Abstract A new species of ghost electric knifefish, Porotergus sambaibensis sp. nov., is described from the Javaés River, a tributary of the Araguaia River in Brazil. The new species was assigned to the genus Porotergus as the closest relative to Porotergus gimbeli through maximum likelihood reconstruction of a concatenated multilocus dataset ...
