“…The high concentration of narrowly endemics at that region of the Espinhaço range may be an indicative of the presence of a pattern similar to that found by Davies et al (2011) We are grateful to the curators of CEN, HBG, NY, P, R, SPF and UB herbaria for providing access to the collec- ogy, chemistry, etc., and, thus, help us to propose stronger phylogenetic hypothesis, particularly for groups with poor resolution on lower levels, as observed in the DNA-based phylogenies of Chamaecrista and Mimosa (Borges et al Chapter 1;Conceição et al 2009;Rando et al unpublished data).…”

Aos que participaram dissoQue é mais que um produto É um processo Don't worry about doing research. Just search. Austin KleonSteal like an artist AGRADECIMENTOS Agradecer a todos que participaram de quatro anos (e um pouco mais) de pesquisas, viagens, alegrias e pirações talvez seja a parte mais difícil de escrever a tese. Primeiro, então, ataca-se a parte mais fácil e objetiva. Agradeço às instituições que ampararam esse doutorado: Instituto de Biocências da Universidade de SãoPaulo, Fundação de Amparo à Pesquisa do Estado de São Paulo, Conselho Nacional de Pesquisa e Desenvolvimento e National Science Foundation (EUA).E agora partimos para a parte mais querida.Expresso toda minha gratidão às seguintes pessoas:Em primeiro lugar aos meus orientadores José Rubens Pirani, por já me conhecer e mesmo assim aceitar continuar a parceria, e Marcelo Fragomeni Simon, que não me conhecia, mas se aventurou mesmo assim. A ajuda, conselhos e conversas foram essenciais para essa tese, mas principalmente, para minha formação. À toda família Aureliano, sempre presente para o que desse e viesse, especialmente à Renilde, que muito me ensinou e nunca me deixou na mão em todos esses anos de amizade fantástica. Talvez o futuro incerto nos separe fisicamente, mas estaremos sempre juntos.Mozzicato, Vinson Doyle, Ricardo Kriebel, Carlos Rodrigues, Elizabeth McCarthy, Julian Aguirre, Liz Kiernan, Nelson Salinas, Nicole Tarnowsky, Charlie Zimmerman, Mike Bevans, Ricardo Kriebel e John MitchAos meus pais Josias e Katia, por misturarem tudo e me fazerem bom e ruim do jeito que sou, particularmente minha mãe, pela firmeza nos anos difíceis. Aos meus irmãos Marcelo e Isabella, sempre parceiros, especialmente minha linda irmãzinha. Não tem jeito, então agradeço também ao meu cunhado Eduardo Vasconcelos Jr. Uma menção mais que especial à minha mais que tia Eny Borges, a qual está sempre com seus pensamentos (e ações) voltados para nós.Dizem por aí que por fim você agradece ao seu grande amor, mas farei diferente.Agradeço pelo próprio amor, dado abundantemente por Deus através de todas as pessoas mencionadas acima e de tantas outras que fizeram parte da minha vida nesses anos.Sem ele, chegar até aqui teria sido muito difícil. Valeu! -Leonardo Maurici Borges

“…Although somewhat beyond the scope of the present work, we propose that the high extinction rates and declining speciation rates may be linked to the evolutionarily young ages of the groups in question and their presence in a biodiversity hotspot (i.e., the H-D Mountains; Myers et al, 2000;Wilson, 1992; http://www.biodiversityhotspots.org/xp/Hotspots; Richardson et al, 2001a,b). A recent study has shown that loss of biodiversity among recent clades in species rich areas is independent of anthropogenic effects and may be part of the natural, stochastic evolutionary course of such species (Davies et al, 2011). Future studies using Lilium-Nomcharis as a model system may seek to better understand the relationships among geomorphology, evolutionary rates, and extinctions within the Q-T Plateau and H-D Mountains regions.…”

“…Studies of several vertebrate groups [2][3][4][5][6][7][8][9] have found that taxa from older and species-poor lineages are most likely to face extinction. Davies et al [10] found the opposite pattern in South African plants: fast-evolving and speciose lineages are more prone to extinction. Selectivity in extinction risk could be explained by evolutionary history, represented by a clade's size and age.…”

Phylogenetic correlates of extinction risk in mammals: species in older lineages are not at greater risk

Phylogenetic information is becoming a recognized basis for evaluating conservation priorities, but associations between extinction risk and properties of a phylogeny such as diversification rates and phylogenetic lineage ages remain unclear. Limited taxon-specific analyses suggest that species in older lineages are at greater risk. We calculate quantitative properties of the mammalian phylogeny and model extinction risk as an ordinal index based on International Union for Conservation of Nature Red List categories. We test for associations between lineage age, clade size, evolutionary distinctiveness and extinction risk for 3308 species of terrestrial mammals. We show no significant global or regional associations, and three significant relationships within taxonomic groups. Extinction risk increases for evolutionarily distinctive primates and decreases with lineage age when lemurs are excluded. Lagomorph species (rabbits, hares and pikas) that have more close relatives are less threatened. We examine the relationship between net diversification rates and extinction risk for 173 genera and find no pattern. We conclude that despite being under-represented in the frequency distribution of lineage ages, species in older, slower evolving and distinct lineages are not more threatened or extinction-prone. Their extinction, however, would represent a disproportionate loss of unique evolutionary history.

Extinction Risk and Diversification Are Linked in a Plant Biodiversity Hotspot

Abstract: Plant extinction risks in the Cape, South Africa differ from those for vertebrates worldwide, with young and fast-evolving plant lineages marching towards extinction at the fastest rate, but independently of human effects.
