Contemporary Management

In the Democratic Republic of the Congo (DRC), the protectionist conservatism influenced by colonialism, which exploited African countries for the prosperity of the colonizing countries, still has a high visibility in the Salonga National Park (PNS). If, in theory, the Central Africans seem to free themselves from the colonial powers on their land, in practice they are still there. The hostility of settlers who have become neo-colonists to the development of Central Africa remains intact, he adds (Ndinga, 2003). This reflects a "logic from above" that has disregarded local values. Yet, in the era of sustainable development and globalization, African protected areas appear to be essential tools for States to reposition themselves in a complex set of actors with the aim of capturing and using the new environmental rent (Giraut, Guyot, & Houssay-Holzschuch, 2003). This is a "bottom-up logic", placing people at the heart of all activities and aiming to reorganize their long-term relationships with the environment. From these two logics, a third "logic from the other side" emerges, reflecting a collective awareness of the fragility of the planet. The restoration of the rights of Africans in the various national frameworks constitutes a major challenge for the contemporary management of African protected areas. Because the protected areas inherited from the different colonial systems must accompany the change in management methods and the redefinition of their functions in order to better serve the local community in the long-term.

A New Species

Here we publish a new species of forest tree of the genus Drypetes Vahl (Putranjivaceae), D. umbricola D. J. Harris & Quintanar, which has a wide distribution in Central Africa (Cameroon, Central African Republic, Democratic Republic of the Congo, Gabon, and Republic of the Congo). It is known from 70 herbarium collections and additional sterile plot vouchers. A differential diagnosis, detailed morphological description, photographs, an illustration, and information about its habitat, distribution, and conservation status are provided.

Restrictive Pattern

Lung function in patients with sickle cell anaemia (SCA) living in sub-Saharan Africa is largely unknown. Anthropometry and spirometry were cross-sectionally evaluated in patients with SCA (HbSS) aged 6–18 years and in schoolchildren from the Democratic Republic of the Congo. The Global Lung Initiative 2012 spirometry reference values were used. A total of 112 patients and 377 controls were included. Twenty-six per cent of patients with SCA had spirometry findings suggestive of a restrictive pattern and 41% had a FEV1 z-score <5th percentile. Wasting, increasing age and female sex were independently associated with increased risk of restrictive spirometry pattern in patients with SCA. Longitudinal studies could clarify the prognostic meaning of these findings.

Three New Species

Three new species of Graphidaceae are described as new to science from tropical Africa: Graphis aptrootiana Van den Broeck, Lücking & Ertz and Redingeria desseiniana Van den Broeck, Lücking & Ertz from the Democratic Republic of the Congo, and G. vandenboomiana Ertz, Lücking & Van den Broeck from Reunion. A key is presented to all known species of Redingeria. The lichenicolous fungus Etayoa trypethelii is mentioned as new to Central Africa.

No Elachistinae have ever been recorded from Cameroon and only one species (Eretmograptis coniodoxa) was described by Meyrick in 1938 from the Democratic Republic of the Congo. Here, we present ten new species of the subfamily Elachistinae from Central Africa: Elachista cordata sp. n., Urodeta absidata sp. n., U. aculeata sp. n., U. crenata sp. n., U. cuspidis sp. n. U. faro sp. n., U. tortuosa sp. n. from Cameroon and U. acerba sp. n., U. bucera sp. n., U. talea sp. n. from the Democratic Republic of the Congo. The new species are diagnosed and illustrated with photographs of the adults and genitalia.

Materials Used

The realization of civil engineering works always produces impacts on the economic and social development of a given region. Some of these impacts can be positive and others negative. In the majority of cases, the options that exist, in relation to the design and project of these works, make it possible to establish a link between the realization of these works, and the materials used for these works while preserving the environment. To illustrate that it is possible to link the development of a region with civil engineering works, this article uses a few examples of materials used in the realization of these works, including wood, which is a natural renewable source that we nd in vast areas in most provinces of the Democratic Republic of Congo being poorly exploited, an optimal management of these woods can effectively contribute to the development of this large country and consequently of Central Africa.

Real Challenge

Lower Congo rock art is concentrated in a region that stretches from Kinshasa to the Atlantic coast and from northern Angola to southern Congo-Brazzaville. Although Lower Congo rock art was identified as early as the 19th century, it had never been a subject of thorough investigation. Presently inhabited by the Ndibu, one of the Kongo subgroups, the Lovo Massif is situated north of the ancient Kongo Kingdom. With 102 sites (including 16 decorated caves), the massif has the largest concentration of rock art in the entire region. In 2008 and 2010, we were able to collect pigment samples directly on the panels of the newly discovered decorated cave of Tovo. Unlike the Sahara and southern Africa, both extensively prospected, rock art of central Africa is still widely unknown and not dated. Radiocarbon dating of rock art in Africa is a real challenge and only a few direct dates have been obtained thus far. After verifying that the pigment samples were indeed charcoal, we proceeded to 14C date them using accelerator mass spectrometry (AMS). The results indicate dates between cal AD 1480 and 1800, confirming that the occupation of Tovo Cave was contemporaneous with the ancient Kongo Kingdom.

Eunotia rudis sp. nov. is described from material collected in acid rivers in an almost pristine tropical rain forest in the Congo Basin in Central Africa. The benthic diatom community was dominated by other Eunotia spp. and small naviculoid taxa. The morphological features of the new species are described and documented based on light and scanning electron microscopy investigations. Eunotia rudis sp. nov. can be distinguished from other taxa within the genus Eunotia by its typical slightly asymmetric valve shape with four dorsal undulations and the rough surface of the thick silica wall. In contrast to other Eunotia species, the number of dorsal undulations was constant in all observed populations. Differences between the new species and the related Eunotia garucisa and E. garucisa var. polydentula are discussed.
