Changes in surface water drive the movements of Shoebills [PDF]

Scientific Reports, 2021
Animal movement is mainly determined by spatial and temporal changes in resource availability. For wetland specialists, the seasonal availability of surface water may be a major determinant of their movement patterns.

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

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 ...

Isotopic systematics of zircon indicate an African affinity for the rocks of southernmost India [PDF]

Scientific Reports, 2020
Southern India lies in an area of Gondwana where multiple blocks are juxtaposed along Moho-penetrating structures, the significance of which are not well understood.

A novel index to aid in prioritizing habitats for site-based conservation. [PDF]

Ecol Evol, 2022
We developed and tested a novel conservation priority index (CPI) that ranks habitats to aid in prioritizing them for conservation. The species richness, endemicity, threat status, and surface area were incorporated in the index. Abstract Funding biodiversity conservation strategies are usually minimal, thus prioritizing habitats at high risk should be

Diversity of the southern Africa Lacustricola Myers, 1924 and redescription of Lacustricola johnstoni (Günther, 1894) and Lacustricola myaposae (Boulenger, 1908) (Cyprinodontiformes, Procatopodidae) [PDF]

ZooKeys, 2020
Through the analysis of a comprehensive database of COI sequences, with the sequencing of 48 specimens, a first insight into the genetic diversity, distribution and relationships between the southern Africa “Lacustricola” species is presented.

New Records and Descriptions of Three New Species of Quadriacanthus (Monopisthocotyla: Dactylogyridae) from Catfishes (Teleostei: Siluriformes, Clariidae) in the Upper Congo Basin [PDF]

Animals
In the Upper Congo Basin, there are few records of monopisthocotylan parasites from clariids. More surveys of clariid fishes can lead to the discovery of multiple monopisthocotylan species that are new to the region or new to science.

First record of epizootic ulcerative syndrome from the Upper Congo catchment: An outbreak in the Bangweulu swamps, Zambia [PDF]

Journal of Fish Diseases, 2017
AbstractWe report on the first outbreak of epizootic ulcerative syndrome (EUS) amongst wild fish populations in the Bangweulu swamps, an inland delta, in the north of Zambia during 2014. The area supports a large and diverse fish fauna related to, but distinct from, that of the Zambezi River system where EUS outbreaks have occurred since 2006.

Modeling land use/land cover changes using quad hybrid machine learning model in Bangweulu wetland and surrounding areas, Zambia

Environmental Challenges, 2023
Wetlands are among the most productive natural ecosystems globally, providing crucial ecosystem services to people. Regrettably, a substantial 64 % –71 % of wetlands have been lost worldwide since 1900, mainly due to changes in land use and land cover ...

Disjunct distributions of freshwater snails testify to a central role of the Congo system in shaping biogeographical patterns in Africa. [PDF]

BMC Evol Biol, 2014
BACKGROUND: The formation of the East African Rift System has decisively influenced the distribution and evolution of tropical Africa´s biota by altering climate conditions, by creating basins for large long-lived lakes, and by affecting the catchment ...
