Pollution and Foraging Behavior of Pied Kingfisher Ceryle rudis in Bujumbura Bay of Lake Tanganyika, Burundi: Conservation Implications [PDF]

open access: yes, 2018
Lake Tanganyika is threatened by overfishing, deforestation, climate change and water pollution. Very few studies have investigated the effects of pollution on semi-aquatic communities such as aquatic birds.

The Victoria Falls, a species boundary for the Zambezi Parrotfish, Cyphomyrus discorhynchus (Peters, 1852), and the resurrection of Cyphomyrus cubangoensis (Pellegrin, 1936) (Mormyridae: Teleostei) [PDF]

open access: yes, 2011
Cyphomyrus discorhynchus occurs in the Zambezi River and in the linked systems of the Kwando and the Okavango. We collected specimens from both above and below the Victoria Falls and recorded Electric Organ Discharges.

The paradox of mosquito net fishing: Complex socio‐ecological trade‐offs in southwestern Madagascar

open access: yesPeople and Nature, EarlyView.
Abstract Small‐scale fisheries are vital for the livelihoods, nutrition and well‐being of millions of people in coastal regions. In many parts of the Global South, rising poverty, limited alternatives and declining resources have driven the spread of mosquito net fishing (MNF), a non‐selective practice using repurposed health‐distributed nets.

Trait coevolution and causal inference using generalized dynamic phylogenetic models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Phylogenetic comparative methods are widely used to study trait coevolution across biological and cultural domains. The most common methods are phylogenetic generalized linear (mixed) models, phylogenetic path analysis, Pagel's ‘discrete’ method and Ornstein–Uhlenbeck models. While some frameworks like generalized linear mixed models are quite

On the measurement of ecological novelty: scale-eating pupfish are separated by 168 my from other scale-eating fishes. [PDF]

open access: yes, 2013
The colonization of new adaptive zones is widely recognized as one of the hallmarks of adaptive radiation. However, the adoption of novel resources during this process is rarely distinguished from phenotypic change because morphology is a common proxy ...

Self‐help and Volunteerism in Tanzania in the 1960s: Voluntary Labour, Nation Building and Constructing Modernity

open access: yesDevelopment and Change, EarlyView.
ABSTRACT The United Nations has declared 2026 the International Year of Volunteers for Sustainable Development. Against that backdrop, this article examines the experience of volunteerism, and specifically self‐help voluntary labour in Tanzania in the early colonial period, to explore the place of volunteerism in the construction of the post‐colonial ...

First insights into the diversity of gill monogeneans of ‘Gnathochromis’ and Limnochromis (Teleostei, Cichlidae) in Burundi: do the parasites mirror host ecology and phylogenetic history? [PDF]

open access: yesPeerJ, 2016
Monogenea is one of the most species-rich groups of parasitic flatworms worldwide, with many species described only recently, which is particularly true for African monogeneans.
