This subfamily is widespread throughout the Neotropics and Ancestral ranges centered in the Andes, presenting an excellent opportunity to study diversification across much of temperate and Andes mid to high-elevation areas of South America. Despite that, no studies have addressed the historical biogeo- Biogeography graphy of the Loasoideae to date, leaving an important knowledge gap in this plant group. Here, we used four Divergence times plastid markers (i.e., trnL–trnF, matK, trnS–trnG, and rps16) and sequenced 170 accessions (134 ingroup taxa) to Loasaceae infer the phylogeny of Loasoideae. We then used this phylogeny as basis to estimate divergence times using an Loasoideae uncorrelated relaxed molecular clock approach and seven fossils as primary calibration points. We employed the Dispersal-Extinction-Cladogenesis (DEC) approach to reconstruct the ancestral ranges of the subfamily. Our results indicate that stem Loasoideae diverged from its sister group in the Late Cretaceous to Early Paleocene (ca.

  • Originis of Mexican Malpighiaceae
    Acta Botanica Mexicana 104: 107-156 (2013) ORIGINS OF MEXICAN MALPIGHIACEAE William R. andeRson University of Michigan Herbarium Ann Arbor, Michigan 48108, USA [email protected] ABSTRACT The approximately 42 lineages of Malpighiaceae currently known in Mexico are identified and briefly described and discussed. All the Mexican lineages have their ultimate roots in South America, although in some cases the connections are inferred only through phylogeny and several Mexican genera probably originated in Mexico. All the lineages have effective adaptations for dispersal except the genus Galphimia, but distributions outside Mexico and a phylogenetic tree suggest that while many Malpighiaceae reached Mexico through “stepping-stone” dispersal, some lineages probably arrived as the result of episodes of long-distance dispersal from South America. Key words: biogeography, Malpighiaceae, Mexico, phylogeny. RESUMEN Se identifican y se describen y discuten brevemente los aproximadamente 42 linajes de Malpighiaceae que se conocen hasta ahora para México. Todos los linajes mexicanos tienen sus últimas raíces en Sudamérica, aunque en algunos casos las conexiones se infieren únicamente mediante filogenia y algunos géneros mexicanos probablemente se originaron en México. Todos los linajes tienen adaptaciones efectivas para su dispersión excepto el género Galphimia, pero las distribuciones fuera de México y un árbol filogenético sugieren que aunque muchas Malpighiaceae llegaron a México mediante el modelo de dispersión de “piedras de paso”, algunos linajes probablemente arribaron desde Sudamérica mediante dispersión a larga distancia. Palabras clave: biogeografía, filogenia, Malpighiaceae, México. 107 Acta Botanica Mexicana 104: 107-156 (2013) INTRODUCTION In a recent review of the literature on the Mexican seasonally dry tropical flora, Pérez-García et al.

  • Induction and Transfer of Resistance to Poisoning by Amorimia (Mascagnia) Septentrionalis in Goats
    Research Article Received: 31 October 2012, Revised: 27 December 2012, Accepted: 27 December 2012 Published online in Wiley Online Library: 12 February 2013 (wileyonlinelibrary.com) DOI 10.1002/jat.2860 Induction and transfer of resistance to poisoning by Amorimia (Mascagnia) septentrionalis in goats Amélia L. L. Duartea, Rosane M. T. Medeirosa, Fabrício K. L. Carvalhoa, Stephen T. Leeb, Daniel Cookb, James A. Pfisterb, Valéria M. M. Costaa and Franklin Riet-Correaa* ABSTRACT: Amorimia septentrionalis contains sodium monofluoroactetate (MFA) and can cause acute heart failure in ruminants when ingested in toxic doses. In this study, we demonstrate that resistance to poisoning by A. septentrionalis can be improved in goats by the repeated administration of non-toxic doses of A. septentrionalis. We also show that increased resistance to poisoning by A. septentrionalis can also be achieved by the transfaunation of ruminal content from goats previously conditioned to be resistant to naïve goats. These methods of improving resistance require further study, but appear to provide potential management solutions to mitigate toxicity problems from A. septentrionalis, and perhaps other plant species containing MFA.

In Northeastern Brazil there are numerous anecdotal accounts indicating that In Brazil, there are at least 12 plants that cause acute heart failure animals grazing in areas invaded by A. rigida are more resistant in ruminants, which are responsible for nearly 500,000 cattle to poisoning than animals introduced from areas where A.

ABSTRACT: In Brazil sodium monofluoroacetate (MFA) containing plants are represented by 16 species that belong to three principle genera: Palicourea (Rubiaceae), Amorimia (Malpighiaceae), and Tanaecium (Bignoniaceae). These plants can cause acute cardiac failure often referred to as sudden death syndrome. The objective of this paper was to determine ifN. stannea contains MFA and to report the clinical signs and pathology of cattle experimentally poisoned by this plant. MFA was detected in all N. stannea plant parts except mature leaves.
