- Madagascar's biota is hyperdiverse and includes exceptional levels of endemicity. We review the current state of knowledge on Madagascar's past and current terrestrial and freshwater biodiversity by compiling and presenting comprehensive data on species diversity, endemism, and rates of species description and human uses, in addition to presenting an updated and simplified map of vegetation types. We report a substantial increase of records and species new to science in recent years; however, the diversity and evolution of many groups remain practically unknown (e.g., fungi and most invertebrates). Digitization efforts are increasing the resolution of species richness patterns and we highlight the crucial role of field- and collections-based research for advancing biodiversity knowledge and identifying gaps in our understanding, particularly as species richness corresponds closely to collection effort. Phylogenetic diversity patterns mirror that of species richness and endemism in most of the analyzed groups. We highlight humid forests as centers of diversity and endemism because of their role as refugia and centers of recent and rapid radiations. However, the distinct endemism of other areas, such as the grassland-woodland mosaic of the Central Highlands and the spiny forest of the southwest, is also biologically important despite lower species richness. The documented uses of Malagasy biodiversity are manifold, with much potential for the uncovering of new useful traits for food, medicine, and climate mitigation. The data presented here showcase Madagascar as a unique " living laboratory" for our understanding of evolution and the complex interactions between people and nature. The gathering and analysis of biodiversity data must continue and accelerate if we are to fully understand and safeguard this unique subset of Earth's biodiversity.

Distribution and ecology of dictyostelids in Madagascar
- 2021

- Samples for isolation of dictyostelid cellular slime molds were obtained from 20 collecting sites at 18 localities in south central and southeastern Madagascar during May 2009. At least thirty species of dictyostelids representing seven genera were recovered from 52 samples of soil/humus. This total included 17 species described as new to science, 13 species already known from various localities throughout the world, and four isolates that remain unidentified. Fourteen of the new species isolated from these samples are members of the whorl-branched, light-spored genus Heterostelium (formerly Polysphondylium). The overall level of species richness of dictyostelids in Madagascar is greater than what is known for all of mainland Africa sampled to date. Levels of biodiversity in Madagascar were higher for mesic than for xeric vegetation types, and each of the newly described species of Heterostelium appeared to have a limited distribution among the localities sampled.

New species of Polysphondylium from Madagascar

- Two series of samples collected for isolation of dictyostelid cellular slime molds (dictyostelids) in Madagascar yielded a relatively large number of isolates of Polysphondylium. Most of these turned out to be species new to science that show varying degrees of clustering from unclustered to coremiform as well as an ability to migrate. Migratory ability (phototaxis) is a common feature of species assigned to Group 2 of the Polysphondylia and is common in the new species from Madagascar. Another common feature, clustering, appears to be a strategy for keeping fruiting bodies erect for a longer time in a climate that is relatively dry, whereas migratory ability may function seasonally when there is more rainfall. Thirteen species are described herein. Each of these is characterized by a particular set of distinguishing features, and collectively they expand our concept of the genus Polysphondylium.

Bristly versus juicy : Phylogenetic position and taxonomy of Sphaerocoma (Caryophyllaceae)
- 2012

Ingår i: Taxon. - 0040-0262 .- 1996-8175. ; 61:1, s. 67-75

Tidskriftsartikel (refereegranskat)abstract
- The phylogenetic position of the Afro-Asian genus Sphaerocoma is investigated using DNA sequences from plastid rps16 and ndhF, as well as from nuclear ITS and RPB2. Seven accessions of Sphaerocoma, representing all three currently recognized taxa, are analyzed along with sequences from genera that have been found to be closely related to Sphaerocoma in broader studies of Caryophyllaceae. The Afro-Arabian Pollichia is indicated as sister to Sphaerocoma, and this Sphaerocoma-Pollichia clade is sister to a clade with Macaronesian Polycarpaea and the widely distributed Polycarpon prostratum. A close relationship between the anemochorous Sphaerocoma and the endozoochorous Pollichia has never previously been suggested, but some similarities in, e.g., floral characters are pointed out. Sphaerocoma is strongly supported as monophyletic, but no significant molecular variation within the genus could be detected. A new taxonomy of Sphaerocoma is proposed, where a single species with two geographically and morphologically defined subspecies are recognized: S. hookeri subsp. hookeri in coastal areas along the Red Sea in Egypt, Sudan and Saudi-Arabia, near Aden in Yemen, and in Somalia, and S. hookeri subsp. aucheri comb. & stat. nov. in coastal areas in south-eastern Yemen, Oman, United Arab Emirates, Bahrain, Iran, and Pakistan. A lectotype is designated for S. hookeri.
