A population of sitatungas (Tragelaphus spekei gratus) living in a forest swamp clearing, Maya Nord, in the Republic of Congo was studied over 3½ years and its grouping patterns and population dynamics were analysed. The sitatungas in this clearing formed a stable group, which remained in residence. The group (16–36 individuals) functioned like a harem. As a result of intrasexual competition, all the males and some of the females born at Maya left the group before reaching sexual maturity. We hypothesize that this large grouping resulted from the development of a tendency for females to be gregarious for reasons related to food availability. This tendency, combined with an aseasonal pattern of reproduction, favours direct monopolization of females by one male. Social and mating strategies observed at Maya fit the model of "female-defence polygyny" (Emlen and Oring). Our results provide an argument in favour of relating food availability and grouping patterns, and underline the plasticity of social organization and mating strategies in sitatungas.

On 12 June 2002, the Ministry of Health of the Republic of Congo reported six suspected cases, including five deaths, of acute haemorrhagic fever syndrome in Mbomo district, near the Gabonese border (1). The first cases occurred in a group of people who had been working in a gold mining camp in a forest south of Oloba. It seems that they may have been exposed to the same source, a chimpanzee found dead in the forest.

Constitutional Factor

Constitutions around Africa have been repeatedly tested on the issue of presidential term limits. We explore the four most recent cases of African presidents facing the end of their constitutionally mandated limit, all of which developed in Central Africa. Burundi, Rwanda, the Republic of Congo, and the Democratic Republic of Congo all adopted constitutions limiting presidential tenure to two terms; yet, in 2015, when these limits were approaching, none of the sitting presidents simply stood down. Our analysis focuses on the constitutional provisions meant to protect the two-term limit, the strategies employed by each of the four presidents, and the difficulty they faced in pursuing extended tenure. We find that constitutional provisions do constrain, but not always to the expected degree. Our analysis adds a consideration of a foundational constitutional factor to the growing literature on term limits in Africa, with implications for other regions of newly developing democracies.

AbstractAspects of human life history and cognition, such as our long childhoods and extensive use of teaching, theoretically evolved to facilitate the acquisition of complex tasks. The present paper empirically examines the relationship between subsistence task difficulty and age of acquisition, rates of teaching, and rates of oblique transmission among Hadza and BaYaka foragers from Tanzania and the Republic of Congo. We further examine cross-cultural variation in how and from whom learning occurred. Learning patterns and community perceptions of task difficulty were assessed through interviews. We found no relationship between task difficulty, age of acquisition, and oblique transmission, and a weak but positive relationship between task difficulty and rates of teaching. While same-sex transmission was normative in both societies, tasks ranked as more difficult were more likely to be transmitted by men among the BaYaka, but not among the Hadza, potentially reflecting cross-cultural differences in the sexual division of subsistence and teaching labor. Further, the BaYaka were more likely to report learning via teaching, and less likely to report learning via observation, than the Hadza, possibly owing to differences in socialization practices.

Abstract Reintroductions of large carnivore species present unique opportunities to model population dynamics as populations can be monitored from the beginning of a reintroduction. However, analysis of the population dynamics of such reintroduced populations is rare and may be limited in incorporating the complex movements and environmental interactions of large carnivores. Starting in 2004, Asiatic black bears Ursus thibetanus were reintroduced and tracked in the Republic of Korea, along with their descendants, using radio telemetry, yielding 33,924 tracking points over 12 years. Along with information about habitat use, landscape, and resource availability, we estimated the population equilibrium and dispersal capability of the reintroduced population. We used a mixed modelling approach to determine suitable habitat areas, population equilibria for three different resources-based scenarios, and least-cost pathways (i.e. corridors) for dispersal. Our population simulations provided a mean population equilibrium of 64 individuals at the original reintroduction site and a potential maximum of 1,438 individuals in the country. The simulation showed that the bear population will disperse to nearby mountainous areas, but a second reintroduction will be required to fully restore U. thibetanus. Northern suitable habitats are currently disconnected and natural re-population is unlikely to happen unless supported. Our methodologies and findings are also relevant for determining the outcome and trajectories of reintroduced populations of other large carnivores.

White Footed Mouse

Food availability often drives consumer population dynamics. However, food availability may also influence capture probability, which if not accounted for may create bias in estimating consumer abundance and confound the effects of food availability on consumer population dynamics. This study compared two commonly used abundance indices (minimum number alive (MNA) and number of animals captured per night per grid) with an abundance estimator based on robust design model as applied to the white-footed mouse ( Peromyscus leucopus (Rafinesque, 1818)) in food supplementation experiments. MNA consistently generated abundance estimates similar to the robust design model, regardless of food supplementation. The number of animals captured per night per grid, however, consistently generated lower abundance estimates compared with MNA and the robust design model. Nevertheless, the correlations between abundance estimates from MNA, number of animals captured, and robust design model were not influenced by food supplementation. This study demonstrated that food supplementation is not likely to create bias among these different measures of abundance. Therefore, there is a great potential for conducting meta-analysis of food supplementation effect on consumer population dynamics (particularly in small mammals) across studies using different abundance indices and estimators.

Gospel Narratives

Majority World readings of Matthew (and the Gospels generally) often help us to appreciate the very sorts of stories that seem most alien to readers in the West: stories of unusual cures and exorcisms of hostile spirits. Rather than simply allegorising these narratives, many Majority World readers treat them as models for experiencing healing and deliverance. Accounts of these experiences appear in a wide variety of cultures; in addition to a range of published sources, the article includes some material based on the author’s interviews with people claiming first-hand experiences of this nature in the Republic of Congo. Such readings invite a more sympathetic hearing of some Gospel narratives than they often receive in the West.
