In this talk, we travel back to the cradle of plant geography both in the literal and figurative sense. I present the results of a 2012 resurvey of Chimborazo, finding strong upward shifts in the vegetation, and discuss some of the challenges and potentials of using historical datasets for documenting biotic responses to global environmental change. We also explore Humboldt’s pioneering insights on the broad-scale patterns of nature and relevance to biogeography. I highlight a few ways in which our understanding of the world has remained much the same as Humboldt’s, and views that have changed drastically thanks to new theories, data, and methods. Finally, I argue that his holistic approach and view that “everything is interconnected” remains ever so important both to the field and for addressing global challenges of the Anthropocene. P2 Hybridization fuels adaptive radiation of cichlid fishes Joana Meier, University of Cambridge; Ole Seehausen, University of Bern and EAWAG, Switzerland Lake Victoria in East Africa was colonized by five different lineages of cichlid fishes. One of them diversified into 500 species, whereas the others did not even speciate once. This is highly replicated among all major lakes in the Lake Victoria Region, whereby always the same lineage diversified in each lake forming so-called adaptive radiations. With genomic and phylogenetic methods, we found that this one lineage is able to diversify rapidly because it is of hybrid origin between two divergent cichlid lineages from different drainage systems. The large genetic variation resulting from the combined gene pools of the two ancestral lineages, facilitated rapid diversification. Even though Lake Victoria is only 15,000 years old, this lineage diversified into 500 species ranging from algae scrapers, molluscivores, and zooplanktivores to large predators. We show that these species really evolved in only 15,000 years in the lake through selection on pre-existing variation that was generated through the hybridization event at the origin of the species group. Similarly, in the African Lake Mweru, we discovered multiple adaptive radiations of cichlid fishes. We found that all of them evolved from hybrid ancestry between two or more ancestral lineages from different drainage systems that came into contact during a river capture event about 1 million years ago. Also in this system the large genetic variation generated during the hybridization event facilitated rapid diversification. We propose that hybridization may be key to rapid diversification in general. Page 7 of 150 PLENARY TALKS (CONT’D) P3 The Origin of Elevational Replacements in Neotropical Birds: Uncovering the Roots of Humboldt’s Elevational Zonation Daniel Cadena, Universidad de los Andes Tropical mountains are biodiversity hotspots. In particular, mountains in the Neotropics exhibit remarkable beta diversity reflecting species turnover along elevational gradients. Elevational replacements of species have been known since early surveys of the tropics as evidenced by work by Alexander von Humboldt on the geography of plants, but data on how such replacements arise are scarce, limiting our understanding of mechanisms underlying patterns of diversity. I will present data from recent studies in which collaborators and I evaluated hypotheses posed to account for the origin of elevational replacements in Neotropical birds including the Henicorhina leucophrys complex (Troglodytidae) and the genus Scytalopus (Rhinocryptidae), two groups with limited dispersal abilities but broad geographic ranges in tropical mountains. Using phylogeographic data for H. leucophrys and a robust molecular phylogeny for Scytalopus, we found that most cases of elevational replacements involve populations or species not closely related to each other. These results, as well as our research on other clades, suggest that replacements of species along elevational gradients result primarily from secondary contact following allopatric speciation and not via parapatric speciation along mountain slopes. Our study suggests that accumulation of species diversity in montane environments reflects colonization processes as opposed to in situ divergence even in dispersal- limited animals.

    Boletín de la Sociedad Entomológica Aragonesa (S.E.A.), nº 47 (2010) : 71‒126. REVISION OF THE GENERA TINIOCELLUS PÉRINGUEY, 1901 AND NITIOCELLUS GEN. N. (COLEOPTERA, SCARABAEIDAE, ONITICELLINI) Tristão Branco Rua de Camões, 788, 2º Dto, P-4000-142 Porto, Portugal − [email protected] Abstract: The taxonomical history of the genus Tiniocellus Péringuey, 1901 and the 10 species-group names that have been associated with it is reviewed, and the reasons that justify the creation of Nitiocellus gen. n. for Oniticellus panthera Boucomont, 1921 and Oniticellus collarti Janssens, 1939, are explained. The taxonomy of the Oniticellini is briefly reviewed and a key is provided for the separation of Tiniocellus and Nitiocellus gen. n. from all the other genera currently ranged in the tribe. The synonymies of Oniticellus variegatus Fåhraeus, 1857 and Oniticellus humilis Gerstaecker, 1871 with Tiniocellus spinipes (Roth, 1851) are confirmed. The Asian Tiniocellus imbellis (Bates, 1891) and the African Tiniocellus setifer (Kraatz, 1895) are rehabilitated as good species. Oniticellus modestus Arrow, 1908 is synonymised with T. imbellis, and Tiniocellus asmarensis Balthasar, 1968 with T. spinipes. Three Afrotropical species, one of them containing two subspecies, are described: T. praetermissus sp. n. from western Africa, T. dolosus sp. n. from eastern, central and western Africa, T. eurypygus sp. n. from South Africa, the nominotypical subspecies from the uplands west of the Drakensberg mountain range, and T. eurypygus transdrakensbergensis ssp. n. from the lowlands east of the same mountain range. Keys are provided to the species and sub- species of Tiniocellus, and to the species of Nitiocellus gen. n. For this study 4,628 specimens were examined, including the name-bearing types of all the species-group names, except that of T.

Hopkins The most effective way to reduce or eliminate pest problems and risks posed by pesticides is to first prevent pests from entering your home. Around the home, pest prevention measures include removing sources of food and water and eliminating pest shelters and breeding sites: • Store food in sealed plastic or glass containers. Make sure food and food scraps are tightly sealed and garbage is regularly removed from the home. Garbage containing food scraps should be placed in tightly covered trash cans. • Fix leaky plumbing and do not let water accumulate anywhere in the structure. Don't let water accumulate in trays under houseplants or under the refrigerator. • Don't leave pet food and water out overnight. Also, if you Before purchasing or using any pesticide, always read and then apply pesticides, pet food and water should be removed carefully follow the directions on from the area. the container label. • Clutter provides shelter for pests-places for roaches and mice to breed and hide-and makes it difficult to provide effective pest control. Keep the level of clutter down. Stacks of newspapers, magazines, or cardboard provide excellent shelter for roaches and other pests.

  • Digit Evolution in Gymnophthalmid Lizards JULIANA G
    Int. J. Dev. Biol. 58: 895-908 (2014) doi: 10.1387/ijdb.140255jg www.intjdevbiol.com Digit evolution in gymnophthalmid lizards JULIANA G. ROSCITO*,1, PEDRO M.S. NUNES2 and MIGUEL T. RODRIGUES1 1Departamento de Zoologia, Instituto de Biociências, Universidade de São Paulo-SP and 2Departamento de Zoologia, Centro de Ciências Biológicas, Universidade Federal de Pernambuco, Brazil ABSTRACT The tetrapod limb is a highly diverse structure, and reduction or loss of this structure accounts for many of the limb phenotypes observed within species. Squamate reptiles are one of the many tetrapod lineages in which the limbs have been greatly modified from the pentadactyl generalized pattern, including different degrees of reduction in the number of limb elements to complete limblessness. Even though limb reduction is widespread, the evolutionary and develop- mental mechanisms involved in the formation of reduced limb morphologies remains unclear. In this study, we present an overview of limb morphology within the microteiid lizard group Gymn- ophthalmidae, focusing on digit arrangement. We show that there are two major groups of limb- reduced gymnophthalmids. The first group is formed by lizard-like (and frequently pentadactyl) species, in which minor reductions (such as the loss of 1-2 phalanges mainly in digits I and V) are the rule; these morphologies generally correspond to those seen in other squamates. The second group is formed by species showing more drastic losses, which can include the absence of an ex- ternally distinct limb in adults. We also present the expression patterns of Sonic Hedgehog (Shh) in the greatly reduced fore and hindlimb of a serpentiform gymnophthalmid.

This study investigates morphometric and genetic differentiation in the T. graeca complex in Turkey using the densest sampling to date. We sequenced two mt-DNA loci (ND4 and cyt b) of 199 samples and combined them with previously published data. Bayesian analysis yielded six well-supported clades, four of which occur in Turkey (ibera, terrestris, armeniaca and buxtoni). The armeniaca mtDNA clade locally represents a morphometrically distinct burrowing ecomorph. However, previous studies have shown that individuals outside Turkey possessing armeniaca mtDNA lack the distinctive armeniaca morphotype we observed, precluding taxonomic conclusions.

Zoological Studies 51(4): 484-493. The diet of the frog Crossodactylus schmidti was studied from Sept. 2009 to Mar. 2010 in the Turvo State Park, a locality of mesophytic semideciduous forest in southern Brazil, based on 93 stomach contents obtained by stomach-flushing (n = 80) and analysis of preserved specimens (n = 13). In addition to describing the diet, we determined the niche breadth on the basis of prey categories, and calculated electivities to evaluate the relation between the diet and prey availability in the environment. We also tested for differences in diets between sexes and between adults and juveniles. Crossodactylus schmidti consumed 19 categories of prey, of which ants, beetles, and dipterans had the highest importance values. Despite the varied diet, the niche breadth was narrow, with only a few prey categories being consumed predominantly. Ants, dipterans, and spiders were consumed in proportions similar to those estimated in the environment.
