Morphometric Analysis Of Subfossil Macronycteris Spp. (Chiroptera: Hipposideridae) From Madagascar, Jamie Lynn Alumbaugh
Morphometric Analysis Of Subfossil Macronycteris Spp. (Chiroptera: Hipposideridae) From Madagascar, Jamie Lynn Alumbaugh
Graduate Research Theses & Dissertations
Macronycteris bats are morphologically conservative between species but demonstrate intraspecific morphological variation between geographic locations and sexes. Two of the four living species of Macronycteris are found on Madagascar, where they are broadly distributed and demonstrate a trend in body size correlated with the latitudinal precipitation cline on the western side of the island. The presence of an extinct species, M. besaoaka, from Anhjohibe Cave in northern Madagascar suggests that Macronycteris was once more diverse, at least with respect to morphology. Since its description, taxonomic and phylogenetic revisions have reshaped our understanding of this genus. On Madagascar, these include the …
Effects Of Habitat Disturbance On The Teeth Of Propithecus Diadema In The Forests Of Tsinjoarivo, Madagascar: Implications For Species Viability And Conservation, Katie Susann Heffernan
Effects Of Habitat Disturbance On The Teeth Of Propithecus Diadema In The Forests Of Tsinjoarivo, Madagascar: Implications For Species Viability And Conservation, Katie Susann Heffernan
Graduate Research Theses & Dissertations
The accelerated transformation of Madagascar’s ecosystems is a direct result of habitat destruction which has devastating consequences for the viability of the island’s animals. This dissertation focuses on the critically endangered diademed sifaka, Propithecus diadema, living in the rainforests of Tsinjoarivo, Madagascar. Tsinjoarivo has been heavily impacted by slash and burn agriculture and transformed into isolated forest fragments. Previous research by Irwin and colleagues has demonstrated that the diet and group dynamics of Propithecus diadema differ between continuous and degraded forests, but whether fragmented landscapes provide tougher foods and lead to behavioral changes through increased tooth wear has not been …
