✨ How Many Endemic Species In Madagascar

In this remote corner of Madagascar, rare raptors roost high in the canopy, flufftails lurk beneath marshland reeds, and the humble pochard, the duck that prompted it all, glides in increasing numbers across smooth mountain lakes. This story originally ran in the Summer 2019 issue as “Treasure Hunters.”. We find that 217 of 541 grass species (electronic supplementary material, S4), or 40%, are endemic to the island. Furthermore, 11 of 140 genera are endemic [49,50]. Madagascar has more endemic grass species in proportion to the total grass flora than most other regions (figure 2a). The highest proportions of grass endemics are recorded for the Endemic fish of Madagascar include two families, 15 genera and over 100 species, primarily inhabiting the island's freshwater lakes and rivers. Although invertebrates remain poorly studied on Madagascar, researchers have found high rates of endemism among the known species. Plot-level bird species richness in seven prevalent land-use types in northeastern Madagascar (n = 10, except fallow-derived vanilla n = 20) for a) all species and b) endemic species only. The black horizontal line represents the median for each land-use type, and the lower and upper hinges of each box correspond to the first and third quartiles. Of all the endemic Malagasy chelonians, E. madagascariensis has the oldest age of sexual maturity at 18–25 years old making the species especially susceptible to population decline if Madagascar is one of the planet’s biodiversity hotspots with 90% of its species found nowhere else on the planet, yet more than half of its mammal species are threatened with extinction. .
