Abstract:

Madagascar was one of the last major land masses to be inhabited by humans. It was initially colonized by Austronesian speaking Indonesians 1500–2000 years ago, but subsequent migration from Africa has resulted in approximately equal genetic contributions from Indonesia and Africa, and the material culture has mainly African influences. The dog, along with the pig and the chicken, was part of the Austronesian Neolithic culture, and was furthermore the only domestic animal to accompany humans to every continent in ancient times.

Abstract:

The Afro-Madagascan genus Craterispermum (Craterispermeae, Rubiaceae) is taxonomically badly known. Hitherto, no species were described from Madagascar, although several taxa occur in the humid lowland forests in the eastern and northern regions of the island. In this contribution three new Madagascan Craterispermum species are described, C. motleyanum, C. puffianum and C. cervicorne. All are illustrated and their distribution is discussed. An identification key for the three new species is given.

Abstract:

Prey animals can reduce their risk of predation by detecting potential predators before encounters occur. Some animals gain information about nearby predators by eavesdropping on heterospecific alarm calls. Despite having well-developed ears, most lizards do not use vocal information for intraspecific communication, and few studies have shown practical use of the ears in wild lizards. Here, we show that the Madagascan spiny-tailed iguana ( Oplurus cuvieri cuvieri ) obtains auditory signals for predator detection.

Abstract:

Abstract The relationships of Madagascan plant and animal taxa have been the object of much fascination, Madagascar sharing numerous lineages with Africa, others with Asia, Australia, or the Americas, and many others being of uncertain relationships. In commonly accepted global regionalization schemata, Madagascar is treated together with Africa for animals, and with Africa, tropical Asia and the Pacific islands in the case of plants. Here we examine the similarities between the biotic assemblages of (i) tropical Africa, (ii) Madagascar, and (iii) the rest of the world, on a basic taxonomic le

Abstract:

Melastomataceae sensu stricto (excluding Memecylaceae) comprise some 3000 species in the neotropics, 1000 in Asia, 240 in Africa, and 230 in Madagascar. Previous family–wide morphological and DNA analyses have shown that the Madagascan species belong to at least three unrelated lineages, which were hypothesized to have arrived by trans–oceanic dispersal. An alternative hypothesis posits that the ancestors of Madagascan, as well as Indian, Melastomataceae arrived from Africa in the Late Cretaceous. This study tests these hypotheses in a Bayesian framework, using three combined sequence datasets

Abstract:

Chameleons of the Madagascan endemic genus Brookesia Gray are small to extremely small reptiles with a mostly terrestrial lifestyle, and due to their low mobility and their camouflage they are nearly invisible in the leaf litter of Madagascar's forests. The genus Brookesia is widely distributed (except in the arid south and south-west) but many Brookesia species are restricted to a relatively small area of the island (Glaw & Vences 2007). Speciation has been most prolific in the northern parts of Madagascar, an area that currently host about two-thirds of the 27 nominal Brookesia species (

Abstract:

The genus Cestradoretus Ohaus, 1912 was erected by Ohaus (1912) to accommodate a Madagascan Adoretini species, C. tenuirostris Ohaus, 1912. This genus is characterized by the adults having the apex of the labrum with a long, fine, acute process curved downwards. In the addition to the above mentioned paper, Ohaus (1912) also described C. acomys Ohaus, 1912 from Tanzania, and later moved Adoretus tarsatus Klug, 1855, described from Mozambique, to Cestradoretus (Ohaus 1916). Later, Machatschke (1965) described two species from Africa, C. freyi Machatschke, 1965 from Botswana and C. minusculus Ma

When Rauh & Hebding in Rauh (1995: 15) suggested the reclassification of the Madagascan K. juelii Raymond-Hamet & Perrier de la Bâthie (1914: 135, as ‘jueli’) as a variety of K. beauverdii Hamet (1907: 887), they did not cite the basionym, with the result that their proposed new combination, ‘Kalanchoe beauverdii Raym.-Hamet var. juelii, as ‘jueli’(Raym.-Hamet

Abstract:

AbstractA new anuran species of the genus Boophis from the rainforests of eastern Madagascar is described. This species differs from the other Boophis by the presence of lateral dermal fringes on the arms, legs and lower lip, and its lichen-like dorsal colouration. It is included in the B. tephraeomystax group due to several morphochromatic characters. Tadpoles probably belonging to this species have a peculiar colouration: black with a bright yellow transverse stripe on the body and a yellow spot at the tip of the snout. Behavioural observations support the assumption that frogs of this speci

Abstract:

A broad overview of the current state of taxonomic knowledge on the Apiaceae of Sub-Saharan Africa and Madagascar is presented. Sub-Saharan Africa has about 69 indigenous genera in the family, with 38 of them endemic, while Madagascar has at least 16 genera, of which six are endemic. Many taxa are poorly known and show unusual combinations of character states. Generic delimitations have not yet reached stability but monographic work, in which morphological, anatomical and some chemical characters are rigorously analysed, is contributing steadily to an improved understanding of generic relation

Gastrodia madagascariensis, a leafless achlorophyllous orchid, is described and illustrated here. The epithet was originally coined by Perrier de la Bâthie in 1939 for fruiting material found on the eastern coastal plain of Madagascar more than a century ago, but the name was never validly published. This new species is closely related to G. similis from Reunion Island, from which it can be distinguished by the perianth tube spreading towards the apex, the shape of the column and stigma, and the flower colour. The achlorophyllous genus Gastrodia currently comprises five species in the tropical

Antisera were made to serum albumin of the African Chamaeleo quilensis and the Madagascan Chamaeleo pardalis. Our results are compared to phylogenetic hypotheses based on other characters (

The recently extinct New Zealand adzebills (Aptornithidae, Aptornis spp.) were an enigmatic group of large flightless birds that have long eluded precise taxonomic assignment as they do not closely resemble any extant birds. Adzebills were nearly wingless, weighed approximately 16–19 kg, and possessed massive adze-like reinforced bills whose function remains unknown. Using hybridisation enrichment and high-throughput sequencing of DNA extracted from subfossil bone and eggshell, near-complete mitochondrial genomes were successfully assembled from the two Quaternary adzebill species: the North I
