Spatio-temporal variation in small mammal species richness, relative abundance and body mass reveal changes in a coastal wetland ecosystem in Ghana

Abstract: Coastal wetlands in Ghana are under severe threat of anthropogenic drivers of habitat degradation and climate change, thereby increasing the need for assessment and monitoring to inform targeted and effective conservation of these ecosystems. Here, we assess small mammal species richness, relative abundance and body mass in three habitats at the Muni-Pomadze Ramsar site of Ghana, and compare these to baseline data gathered in 1997 to evaluate changes in the wetland ecosystem. Small mammals were live-trapped us… Show more

“…Les différents peuplements des communautés de petits rongeurs ont été caractérisés à l'aide des indices d'abondance relative et de diversité. Pour évaluer les différences entre les compositions et les structures des peuplements des communautés, l'analyse des données a été réalisée à l'aide des packages pgirmess R (Giraudoux et (Ofori et al, 2016). L'abondance relative (Pi) qui est l'expression de l'importance de chacune des espèces par rapport à toutes celles enregistrées dans un habitat a été calculée à l'aide de la formule suivante : Pi = (ni/N) x 100 ; avec ni = nombre d'individus de l'espèce i ; N = nombre total de spécimens capturés.…”

“…This is why several animals are used as biological indicators to assess habitat's quality. Among terrestrial small mammals, shrews and rodents communities have demonstrated their great ability to reflect the state of conservation of their environment (Decher et al, 2010;Avenant, 2011;Ofori et al, 2016). Thus, survey of shrews and rodents communities has become an integral part of environmental and social impact assessments (Avenant, 2011;Ofori et al, 2016).…”

This paper presents species richness and relative abundances of terrestrial small mammals at four blocks of Sime Darby Gross Concession Area (GCA) showing different environments in Bong and Gbarpolu counties.…”

“…The order Rodentia is documented as the largest order of mammals with about 2277 species worldwide, while insectivore fauna is of 429 species with more than 70% being shrews (Kingdon, 1997). Rodents and insectivores are important components of many terrestrial ecosystems, as major consumers of primary productivity, as well as important prey for many vertebrate predators (Ofori et al, 2016). Alterations in the community structure of these small mammals can be used as alternative and a quick way of measuring environmental disturbance, due to their sensitivity to small changes in the environment (Avenant, 2011;Ofori et al, 2016).…”
