I tried as well to present my BioArea but we did not have Museum of Natural History in Madagascar. Even if all the Earth is under climate change, habitat loss and loss of biodiversity pressure, either there are authorities working on conservation patterns and protected areas in Madagascar, its case seems to be worsted by political, demographical, agricultural and economical situations.

It would be great to receive your evaluation

1. Your BioArea needs some elaboration and enrichment.

2. Your BioArea is looking good.

3. Your BioArea is looking excellent!

1) Cases of lemurs :  (Propithecus coronatus) and Decken’s sifaka (Propithecus deckenii)
2) Cases of trees in forests :
- Cadotte et al. (2002) surveyed the vegetation of three littoral forest fragments in Sainte Luce and one fragment in Lokaro to the north of Tolagnaro. The Lokaro fragment is closer to the sea, more isolated and more heavily impacted by local communities than the Sainte Luce fragments, and contained significantly fewer species and families than the latter forest blocks. The Lokaro fragment also demonstrated significantly lower tree density.
- Sussman & Rakotozafy (1994) investigated forest structure and composition in three areas at Beza Mahafaly: gallery forest on humid soils, spiny thicket on dry soils (both of which were fenced and therefore not subject to grazing), and an unfenced patch of spiny thicket on dry soils. They found tree density to be lower in the grazed area than the equivalent, fenced spiny thicket area, but higher than in the gallery forest. The grazed forest also had a higher proportion of indigenous trees than the fenced areas, although indigenous tree species richness was lower.

Given its geographic location, Madagascar is regularly subject to powerful cyclones that damage ecosystems and infrastructure, particularly on the coasts, and climate change is predicted to increase both their number and severity. In addition, rainfall patterns in some areas of the country will intensify leading to increased flooding and erosion, while rainfall in the south will lessen and become more unpredictable. The prolonged drought in the south has already caused extensive hardship for people living there and the long-term toll on the region’s biological resources has yet to be fully assessed. Increased carbon dioxide levels in the atmosphere are leading to rising sea temperatures and ocean acidity levels, which threaten coral ecosystems and other marine habitats of high economic and ecological value. Finally, sea level rise around Madagascar, which has the longest coastline of any country in Africa, will subject communities and habitats to increased damage from cyclonic and flooding events and may force many people permanently from their homes.

Each bioarea has his particularities, in terms of biodiversity resources are differently formed. Most of similarities are facts on the threats. All parts of the world are under pressure by overexploitation, climate change, loss of habitat and invasive species and so on.

The main issue is that human does not awake about how critical is the situation. Because globalization teached for a long time a scheme of "a civilized society" focusing ofocusing on individual performance to have a place inside a consumer society.

But always, there is hope. All people should act together facing the loss of biodiversity. An important step is to encompass biodiversity and civilization aspects of each bioarea. Collecting materials for museum has great input important for research and biodiversity conservation. But "real histories" of each people of each patches of the Earth can tell much what is the role even of a single species. "There is always hope." as said Dr. Jane Goodall

Food partitioning among Malagasy primates

Food partitioning among lemurs was studied in relation to food patch size and plant chemistry in the eastern rainforest and a western deciduous forest of Madagascar. Patch size (i.e. crown diameter of food trees) is significantly correlated with group body weight of different lemur species. But intraspecific variability is high and prevents effective species separation. Chemical analyses of more than 400 plant parts eaten by seven different lemur species revealed major differences in their food choice with respect to protein concentrations, condensed tannins and alkaloids. Among the leaf eating lemurs discriminant analysis segregates three groups two species based on chemical characteristics of their food. Whereas differences in food chemistry are pronounced between groups they are lacking between the two species within each group. The two species of each group avoid interference competition by different activity rhythms. Actual competition for slowly renewable resources such as leaves and fruit, however, can not be reduced by different activities. Here interspecific differences in gross categories of food, food species composition and different habitat utilization due to other constraints may contribute to the possible coexistence of species. Thus interspecific differences in food selection in relation to primary and secondary plant chemicals is an integrated part of the mechanisms allowing several primate species to coexist in sympatry.

The Malagasy orogeny and more...
After dislocation, Madagascar inherited the shape of a slightly inclined left foot, whose big toe would be the Cap d'Ambre, the little toe Cap Saint André and the heel Cape Sainte Marie, as if the geological mutations had wanted to leave their footprint. Located 400 km from the East African coast, stretched over 1600 km from Cap d'Ambre in the North to Cape Sainte Marie in the far south, Madagascar is 592,000 km2. The fourth largest island in the world, it aligns a coastline of 5,000 km with a very marked difference between the western coast well protected from the trade winds and that from the east offered to the powerful swell of the Indian Ocean. A kind of backbone made of high peaks separates Madagascar in two asymmetrical parts in the direction of the length.

1)   The Madagascar hissing cockroach (Gromphadorhina portentosa) They are excellent climbers and can scale smooth glass. Males can be distinguished from females by their thicker, hairier antennae and the very pronounced "horns" on the pronotum. Females carry the ootheca internally, and release the young nymphs only after her offspring have emerged within her. As in some other wood-inhabiting roaches, the parents and offspring will commonly remain in close physical contact for extended periods of time. In captivity, these insects have been known to live up to 5 years. They feed primarily on vegetable material.

2) Myzopoda aurita :  Because of their unique habitat, sucker-footed bats don't carry ectoparasites, due to the smooth surface of the Ravenala leaves being inhospitable to small arthropods. The majority of sucker-footed bats caught in eastern Madagascar were within or close to stands of traveller's trees, and according to research, the maximum distance they will travel while foraging is about 1.8 km (1.1 mi).Sucker-footed bats feed largely on beetles and small moths.

Bats feed on arthropods.
Two communities of bats from two localities do not show the same species richness.
There are differences between diveristy and proportion of insects that bats prey. Seems that the biggest bat species in size have most restricted diet choices ;)
But it is confirmed that tehre is more fuctional diversity within a community with highest species richness.
Insectivorous bats could help by providing lots of ecosystem services and especially on pest controlling.
