Kinixys homeana Bell 1827 – Home’s Hinge-Back Tortoise

Analyse de situation de l'UICN concernant la faune terrestre et d'eau douce en Afrique centrale et de l'Ouest

“…Luiselli et al (2006) ont estimé peu probable que cette espèce puisse résister aux niveaux de pression actuels au-delà de 2-3 générations (15 ans). Les prélèvements annuels ont été estimés à 236 532 individus, soit environ 5,6 % de la population totale, mais ces chiffres reposent sur des relevés effectués dans les parcs nationaux, avec une faible densité humaine, et comme ces sites couvrent moins de 3 % de l'aire de répartition, le nombre total de prélèvements réels doit être bien plus élevé (Luiselli & Diagne 2013). Les relevés effectués sur les marchés de viande de brousse dans le sud du Nigeria en 2013 ont indiqué que cette espèce était bien moins courante que 10 ans plus tôt, et elle a complètement disparu de deux marchés du delta du Niger sur lesquels elle était autrefois courante .…”

Kinixys erosa (Schweigger 1812) – Forest Hinge-back Tortoise, Serrated Hinge-back Tortoise, Serrated Hinged Tortoise.

“…According to Broadley Testudinidae -Kinixys erosa 084.7 (1989) it inhabits lowland evergreen forest, marshy areas, and forest galleries growing along rivers and streams, where it is locally threatened by clearance of forest for cultivation, e.g., around Nfainchang (Lawson 1993). In Nigeria, its abundance tends to increase in hilly forests, whereas the relative abundance of K. homeana tends to decrease with altitude (Luiselli and Diagne 2013), so that K. homeana tends to be more abundant in the Niger Delta forests and K. erosa more abundant in Cross River National Park. All authorities agree in considering this species a typical inhabitant of dense forests.…”

“…-Most of the data available on the habitat preferences of K. erosa populations are based on anecdotal observations. It is generally reported that this species occurs in forests throughout its range, generally of a wetter type than the forests inhabited by K. homeana, according to Ernst and Barbour (1989), but of a drier type than K. homeana in Cameroon and Nigeria (Luiselli and Diagne 2013). According to Broadley Testudinidae -Kinixys erosa 084.7 (1989) it inhabits lowland evergreen forest, marshy areas, and forest galleries growing along rivers and streams, where it is locally threatened by clearance of forest for cultivation, e.g., around Nfainchang (Lawson 1993).…”

“…-The species is threatened by subsistence hunting by local people living in desperately poor economic conditions (Noss 1998;Lawson 2000, Luiselli 2003c), agricultural and industrial expansion and deforestation (Akani et al 1998;Segniagbeto et al 2015a), and trade for the pet industry (Harris 2001;Ineich 2011). These threats are particularly strong in southern Nigeria (Luiselli and Diagne 2013), where heavy deforestation occurs due to oil and natural gas industry development, this region being the most important oil-producing zone in all of Africa (Akani et al 1998;Akani and Luiselli 2010).…”

Aspects of the ecology of the tortoiseKinixys nogueyi(Lataste, 1886) in Togo and Nigeria (West Africa)

“…Aspects of the ecology of the tortoise Kinixys nogueyi (Lataste, 1886) in Togo and Nigeria (West Africa) Introduction Tortoises of the genus Kinixys Bell, 1827 are endemic to Africa (Branch 2007) and are declining rapidly throughout the continent (Mifsud and Stapleton 2014), particularly in West Africa (e.g., Luiselli and Diagne 2013). As a consequence, urgent management is required to conserve these species, especially those that are most endangered (Luiselli and Diagne 2013;Mifsud and Stapleton 2014).…”
