Frogs of the genus <em>Phrynobatrachus </em>Günther, 1862 are endemic to sub-Saharan Africa. These are increasingly threatened by a number of factors and are believed to be declining. We report on captive breeding experiments involving <em>Phrynobatrachus auritus</em> Boulenger, 1900. We provide a comprehensive life history for this frog with emphasize on tadpole development time, as well as a description of both the advertisement call and calling behaviour of the adult.

This book charts the transformation of one of the world's great religions during an age marked by world wars, genocide, nationalism, decolonization, and powerful ideological currents, many of them hostile to Christianity. The book traces how Christianity evolved from a religion defined by the culture and politics of Europe to the expanding polycentric and multicultural faith it is today—one whose growing popular support is strongest in sub-Saharan Africa, Latin America, China, and other parts of Asia. The book sheds critical light on themes of central importance for understanding the global contours of modern Christianity, illustrating each one with contrasting case studies, usually taken from different parts of the world. Unlike other books on world Christianity, this one is not a regional survey or chronological narrative, nor does it focus on theology or ecclesiastical institutions. The book provides a history of Christianity as a popular faith experienced and lived by its adherents, telling a compelling and multifaceted story of Christendom's fortunes in Europe, North America, and across the rest of the globe. It demonstrates how Christianity has had less to fear from the onslaughts of secularism than from the readiness of Christians themselves to accommodate their faith to ideologies that privilege racial identity or radical individualism.

In East Africa, the prevalent Bemisia tabaci whiteflies on the food security crop cassava are classified as sub-Saharan Africa (SSA) species. Economically damaging cassava whitefly populations were associated with the SSA2 species in the 1990s, but more recently, it has been to SSA1 species. To investigate whether biological traits (number of first instar nymphs, emerged adults, proportion of females in progeny and development time) of the cassava whitefly species are significant drivers of the observed field abundance, our study determined the development of SSA1 sub-group (SG) 1 (5 populations), SG2 (5 populations), SG3 (1 population) and SSA2 (1 population) on cassava and eggplant under laboratory conditions. SSA1-(SG1-SG2) and SSA2 populations’ development traits were similar. Regardless of the host plant, SSA1-SG2 populations had the highest number of first instar nymphs (60.6 ± 3.4) and emerged adults (50.9 ± 3.6), followed by SSA1-SG1 (55.5 ± 3.2 and 44.6 ± 3.3), SSA2 (45.8 ± 5.7 and 32.6 ± 5.1) and the lowest were SSA1-SG3 (34.2 ± 6.1 and 32.0 ± 7.1) populations. SSA1-SG3 population had the shortest egg–adult emergence development time (26.7 days), followed by SSA1-SG1 (29.1 days), SSA1-SG2 (29.6 days) and SSA2 (32.2 days). Regardless of the whitefly population, development time was significantly shorter on eggplant (25.1 ± 0.9 days) than cassava (34.6 ± 1.0 days). These results support that SSA1-(SG1-SG2) and SSA2 B. tabaci can become highly abundant on cassava, with their species classification alone not correlating with observed abundance and prevalence.

The crossroads of nationalist historiographies in sub-Saharan Africa and of the history of developmentalist attempts that characterise the European late colonial states, have left us with very incomplete images of important trajectories. In the seemingly more “liberal” large colonial empires—notably the French and British—sails were set by 1945 towards a policy of investment and economic change. Some of the scholarly debates question whether this investment was genuine or just a last resort to avoid (rapid) decolonisation; others put the emphasis on inadequate routines of development implemented in these territories, many of which have apparently been continued since decolonisation.In this context, we encounter a clear lack of understanding about how decisions made by individual actors on the administrative level interacted with the larger panorama of social conditions in colonial territories, and of the consequences that these interactions had for the paths towards decolonisation. For a smaller empire such as the Belgian colony of Congo-Léopoldville, these processes are still more obscure; and for the colonies ruled by authoritarian metropoles, as in the cases of territories under Spanish and Portuguese rule, stagnation and absence of change are often taken for granted. In other words, these territories, which were under the rule of metropoles regarded as rather weak in economic terms, are treated as unrepresentative of the broader, European movement towards change in colonial policies. However, the conditions of change towards economic and social modernisation in this latter group of empires, even when inhibited by lack of funding and weak professionalisation of the administration, are frequently very telling for the broader range of challenges that the late colonial states faced.

Gabon, a small oil-rich country straddling the equator on the west coast of Africa, is the wealthiest of France’s former colonies. An early period of colonization in the 19th century resulted in disease, famine, and economic failure. The creation of French Equatorial Africa in 1910 marked the beginning of the sustained lucrative exploitation of Gabon’s natural resources. Gabon began off-shore oil production while still a colony of France. Uranium was also discovered in the last decade of the French Equatorial African empire. Coupled with rich reserves in tropical woods, Gabon has achieved, since independence in 1960, a higher level of export revenue per capita of population than any other country in sub-Saharan Africa in the postcolonial era. However, significant inequality has characterized access to wealth through paid employment throughout the recorded history of monetized labor. While fortunes have been amassed by a minute proportion of the female population of Gabon associated with the ruling regime, and a professional female middle-class has emerged, inequalities of opportunity and reward continue to mark women’s experience of life in this little-known country of West Central Africa. The key challenge facing scholars researching the history of women in Gabon remains the relative lack of historical resources. While significant strides have been made over the past decade, research on women’s history in Francophone Africa published in English or French remains embryonic. French research on African women began to make a mark in the last decade of colonization, notably with the work of Denise Paulme, but then remained a neglected area for decades. The publication in 1994 of Les Africaines by French historian Catherine Coquery-Vidrovitch was hailed at the time as a pioneering work in French historiography. But even this new research contained no analysis of and only a passing reference to women in Gabon.

This chapter looks at the history of romantic love in Sub-Saharan Africa. This text comes from a lecture given at the British Academy's 2009 Raleigh Lecture on History. This text attempts to explore some of the methodological and theoretical issues involved in an historical study of love in Africa. It argues that romantic love in Africa is not simply an extension of an imperialist cultural and political project and that emotional regimes cannot be divorced from economic circumstances. It explains that though the configurations of interest and emotion take specific forms in African societies, there is nothing peculiarly African about the evident need of individuals to balance realism and idealism in their emotional lives.

Abstract A long-standing enigma concerns the geographic and ecological origins of the intensively studied vinegar fly, Drosophila melanogaster. This globally distributed human commensal is thought to originate from sub-Saharan Africa, yet until recently, it had never been reported from undisturbed wilderness environments that could reflect its precommensal niche. Here, we document the collection of 288 D. melanogaster individuals from multiple African wilderness areas in Zambia, Zimbabwe, and Namibia. The presence of D. melanogaster in these remote woodland environments is consistent with an ancestral range in southern-central Africa, as opposed to equatorial regions. After sequencing the genomes of 17 wilderness-collected flies collected from Kafue National Park in Zambia, we found reduced genetic diversity relative to town populations, elevated chromosomal inversion frequencies, and strong differences at specific genes including known insecticide targets. Combining these genomes with existing data, we probed the history of this species’ geographic expansion. Demographic estimates indicated that expansion from southern-central Africa began ∼13,000 years ago, with a Saharan crossing soon after, but expansion from the Middle East into Europe did not begin until roughly 1,800 years ago. This improved model of demographic history will provide an important resource for future evolutionary and genomic studies of this key model organism. Our findings add context to the history of D. melanogaster, while opening the door for future studies on the biological basis of adaptation to human environments.

The history of African film began in the 1960s with the independence of the colonies. Despite all kinds of political and economic difficulties, numerous films have been made since then, featuring wide-ranging processes of consolidation, differentiation and transformation which were characteristic of post-colonial sub-Saharan Africa. However, these feature films should not merely be viewed as back references to specifically African problems. The glimmering fictions are imagination spaces. They preserve ideas about how the post-colonial circumstances should be approached. Seen from this perspective, the history of African film may be studied as a history of African utopias.

Nyctimantis rugiceps Boulenger, 1882 (Fig. 1A) is a Neotropical treefrog (Duellman & Trueb 1976; Faivovich et al. 2005) known only from disjunct localities in Amazonian Colombia, Ecuador, and Peru (Pérez-Villota et al. 2009). This species has the skin of the skull co-ossified and reproduces—including calling behavior, egg deposition and tadpole development—in water-filled tree or bamboo cavities (Duellman & Trueb 1976; Duellman 1978). Given its secretive behavior, this is a poorly known species and, as noted by Duellman (1978: 169), “the major clue to the life history of Nyctimantis is the calling behavior of the males”. Unfortunately, the only quantitative description of the advertisement call of N. rugiceps is a brief passage in Duellman (1978) based on four specimens from Santa Cecilia, Ecuador, where important variables are missing (e.g., call duration). More importantly, graphs illustrating the waveform and spectrogram are missing. Considering these limitations and the importance of advertisement calls to the study of anurans (Köhler et al. 2017), we provide a quantitative description using a call recording obtained in Leticia, Amazonas, Colombia.

The continued influence of traditional governance in sub-Saharan Africa has sparked increasing attention among scholars exploring the role of non-state and quasi-state forms of governance in the modern state. However, little attention has been given to cross-country and over-time variation in the interaction between state and traditional governance structures, particularly in regard to its implications for intrastate peace. This study examines the conditions under which traditional governance contributes to state capacity to maintain peace. The article argues that the type of institutional interaction between the state and traditional authority structures influences a country’s overall governance dynamics and its capacity to maintain peace. By combining new data on state–traditional authorities’ interaction in sub-Saharan Africa from 1989 to 2012 with intrastate armed conflict data, I conduct a systematic comparative analysis of whether concordant state–traditional authorities’ interaction strengthens peace. The empirical results support the argument that integrating traditional authorities into the public administration lowers the risk of armed conflict in comparison to when they remain unrecognized by the state. Moreover, the analysis suggests that the added value of this type of interaction is conditional on the colonial history of a country.
