“…-Indigofereae is a pantropical, mainly woody tribe, with extensions into the subtropics and the Mediterranean-type Fynbos biome of southern Africa. It is placed as sister to the Millettioid group (Hu & al., 2000;Kajita & al., 2001) and has been well characterised in studies by Schrire and collaborators (see Schrire & al., 2009). The Indigofereae is strongly supported as monophyletic with the novel finding that the monospecific Madagascan Disynstemon R.…”

“…The Indigofereae is strongly supported as monophyletic with the novel finding that the monospecific Madagascan Disynstemon R. Vig., previously placed in tribe Millettieae, is sister to the tribe (Schrire & al., 2009). With insufficient apomorphies to expand the circumscription of Indigofereae to include this genus, Schrire & al. maintain it as part of a basal grade, together with Xeroderris Roberty, Dalbergiella Baker f., Platycyamus Benth.…”

“…We sequenced 29 accessions of C. mathewsii (Table S2), collected from diverse locations in Mantaro (9 accessions), Apurimac (9 accessions), Marañon (5 accessions), and Loja (6 accessions) for the ITS region, including the 5.8S subunit, according to methods of Schrire et al (35). To assess the monophyly of C. mathewsii and to ensure that age estimation was not biased by inadequate sampling of related taxa (cf.…”

The Andes are the most species-rich global biodiversity hotspot. Most research and conservation attention in the Andes has focused on biomes such as rain forest, cloud forest, and páramo, where much plant species diversity is the hypothesized result of rapid speciation associated with the recent Andean orogeny. In contrast to these mesic biomes, we present evidence for a different, older diversification history in seasonally dry tropical forests (SDTF) occupying rain-shadowed inter-Andean valleys. High DNA sequence divergence in Cyathostegia mathewsii, a shrub endemic to interAndean SDTF, indicates isolation for at least 5 million years of populations separated by only ca. 600 km of high cordillera in Peru. In conjunction with fossil evidence indicating the presence of SDTF in the Andes in the late Miocene, our data suggest that the disjunct small valley pockets of inter-Andean SDTF have persisted over millions of years. These forests are rich in endemic species but massively impacted, and merit better representation in future plans for science and conservation in Andean countries.biogeography | dispersal limitation | Neotropics | phylogenetic niche conservatism | phylogeography G eotemporal patterns of historical species assembly in the world's biodiversity hotspots and especially in species-rich tropical biomes are poorly understood. Many questions remain to be answered about how the biota of biodiversity hotspots were assembled and how comparable different hotspots are. To gain insights into these questions, we investigate plant species diversification in the tropical Andes, which contain ca. 40,000 plant species, ≈15% of the global total, in only 1% of the world's land area. Most of this diversity is found in the lowland and midelevation mesic forests of the Andean flanks. The "excess" of species in these forests largely explains why the Neotropics contain more plant species than both tropical Africa and Asia, and was hypothesized by Gentry (1, 2) to have been produced by recent, rapid species diversification coinciding with the accelerated orogeny of the Andes over the past 10 million years. Gentry's recent-species diversification model has received support from several dated phylogenies of plant clades with distributions

The Occurrence and Toxicity of Indospicine to Grazing Animals

Indospicine is a non-proteinogenic amino acid which occurs in Indigofera species with widespread prevalence in grazing pastures across tropical Africa, Asia, Australia, and the Americas. It accumulates in the tissues of grazing livestock after ingestion of Indigofera. It is a competitive inhibitor of arginase and causes both liver degeneration and abortion. Indospicine hepatoxicity occurs universally across animal species but the degree varies considerably between species, with dogs being particularly sensitive. The magnitude of canine sensitivity is such that ingestion of naturally indospicine-contaminated horse and camel meat has caused secondary poisoning of dogs, raising significant industry concern. Indospicine impacts on the health and production of grazing animals per se has been less widely documented. Livestock grazing Indigofera have a chronic and cumulative exposure to this toxin, with such exposure experimentally shown to induce both hepatotoxicity and embryo-lethal effects in cattle and sheep. In extensive pasture systems, where animals are not closely monitored, the resultant toxicosis may well occur after prolonged exposure but either be undetected, or even if detected not be attributable to a particular cause. Indospicine should be considered as a possible cause of animal poor performance, particularly reduced weight gain or reproductive losses, in pastures where Indigofera are prevalent.
