The Burundi Heart Centre: From concept to design. [PDF]

open access: yes, 2015
Burundi is one of the worlds poorest nations, which is also reflected in its relative lack of cardiac facilities, particularly those catering to young children and adults.

An Approach for the Assessment of Climate Smart Technologies for Fisheries and Aquaculture in an Afrotropical System

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Climate variability and environmental stressors increasingly undermine the productivity and stability of fisheries and aquaculture systems across regions. Although technologies, such as recirculating aquaculture systems (RAS), integrated aquaculture–agriculture (IAA), Biofloc systems and solar powered hatcheries, have been promoted as climate ...

Expression variations in ectodysplasin-A gene (eda) may contribute to morphological divergence of scales in haplochromine cichlids

open access: yesBMC Ecology and Evolution, 2022
Background Elasmoid scales are one of the most common dermal appendages and can be found in almost all species of bony fish differing greatly in their shape.

Diazotrophic Cyanobacteria are Associated With a Low Nitrate Resupply to Surface Waters in Lake Tanganyika

open access: yesFrontiers in Environmental Science, 2021
In Lake Tanganyika, blooms of nitrogen-fixing (diazotrophic) cyanobacteria emerge, when the upper water column re-stratifies after a period of upwelling and convective mixing.

Evolutionary History of Lake Tanganyika’s Predatory Deepwater Cichlids [PDF]

open access: yesInternational Journal of Evolutionary Biology, 2012
Hybridization among littoral cichlid species in Lake Tanganyika was inferred in several molecular phylogenetic studies. The phenomenon is generally attributed to the lake level-induced shoreline and habitat changes. These allow for allopatric divergence of geographically fragmented populations alternating with locally restricted secondary contact and ...

Performance of Lacustrine Protected Areas (LPAs) on Lake Victoria: A Case of Bulago, Uganda

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Bulago Lacustrine Protected Area (LPA) on Lake Victoria, Uganda, serves as a sanctuary for fish stocks and biodiversity. This study assesses fish catch per unit effort (CPUE) within LPA and in fishing grounds outside LPA. Using five years of quarterly data, CPUE outside LPA rises first, then declines due to increased effort, with southern sites ...

Impact of Load Shedding on Fresh Fish Suppliers and Consumers in Chinsali District, Zambia

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Fresh fish is highly perishable and requires an efficient cold chain to maintain quality and safety. In Zambia, recurrent load shedding disrupts refrigeration and storage systems, increasing the risk of post‐harvest losses and food safety. This study examined the effects of load shedding on fresh fish handling, supply and consumer access in ...

Depositional and stratigraphic evolution of a Permian megalake system: Implications for seiche‐influenced models

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Testing Models for Upper Mantle Earthquakes in the Tanganyika‐Rukwa Rift, Africa

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Rifts that initiate in mechanically strong, stable continental lithosphere are characterized by M > 5 earthquakes at depths >35 km near or below the crust mantle interface. Current models for deep rift zone earthquakes invoke elevated pore pressures associated with magmatism, and rapid stressing from magma intrusions.

Assembly processes of gastropod community change with horizontal and vertical zonation in ancient Lake Ohrid: a metacommunity speciation perspective [PDF]

open access: yes, 2016
The Balkan Lake Ohrid is the oldest and most diverse freshwater lacustrine system in Europe. However, it remains unclear whether species community composition, as well as the diversification of its endemic taxa, is mainly driven by dispersal limitation ...
