As a case study, the project will focus on the Eastern Arc Mountain Range (EAM) in Kenya and Tanzania, a region of exceptional biodiversity and endemism
, but which has lost most (80 %) of its native forest cover.
In this context, studies of fern biogeography have focused on the dispersal capability of spores to account for the low levels of endemism
and reduced geographic differentiation observed in fern species (Barrington, 1993; Kato, 1993; Kramer, 1990, 1993; Shepherd et al.
Kerry O'Neill from Secret Compass, said, “Madagascar is referred to as 'the 8th continent' for the richness and endemism
of its flora and fauna, yet much of this is threatened by encroaching deforestation.
The senior researcher emphasised that now endemism
( occurrence) pattern and conservation requirements of these amphibians need to be looked into.
In this study, two selected caves from Glan, Sarangani Province and one cave from Wao, Lanao del Sur were assessed to determine the species richness, diversity, relative abundance, and endemism
of reptiles and amphibians.
These authors discussed endemism
within the archipelago and increased our understanding of species distributions across these islands.
Thus, in this contribution, we use the historical biogeographic method of Parsimony Analysis of Endemicity (PAE) to examine patterns of endemism
and dispersal within Laurentia and between Laurentia and Baltica before and during the Richmondian Invasion.
Our priority was to try to identify the possibility of endemism
at the national scale by carefully studying the known biogeographical information.
The Balsas Basin is one of the biggest and most important basins in Mexico with an abundance and endemism
of plant and animal species brought about by the confluence of the Nearctic and Neotropical regions (Rzendowski, 1991; Flores and Gerez, 1994; Escalante et al.
Madagascar is a priority country for international conservation efforts, due to its unparalleled levels of endemism
(80% of species in Madagascar are found nowhere else on earth), biodiversity (it is home to approximately 5% of the world's plant and animal species) and rates of habitat loss, especially through deforestation to open up farming land, industrial logging and mineral resource extraction.
Examples of relictual and autochthonous endemism
among island taxa will be described and adaptive radiation among successful island colonizers will be emphasized.
Additionally, a fish survey conducted in 2013 in rivers in the Herakles Farms plantation area found high levels of endemism
and diversity and concluded that the rivers were of extreme aquatic conservation value.
