Systematics And Biogeography Of The Didymopanax Group Of Schefflera (Araliaceae), Pedro Fiaschi

Theses and Dissertations

Schefflera is the largest genus in the angiosperm family Araliaceae, with about 900 species, of which c. 300 belong to five subgeneric groups in the Neotropical region. Previous phylogenetic studies of Schefflera have been limited to a small number of species from this region, and very little is know about phylogenetic relationships in the Brazilian-centered Didymopanax group of this genus. Therefore, to gain a better understanding of the diversity and evolution of the Didymopanax group of Schefflera, I investigated the systematics of these plants in the broader context of the entire Neotropical clade. The main goals were (1) to investigate …

Taxonomic Overview Of The Greater Fritillary Genus Speyeria Scudder And The Atlantis - Hesperis Species Complexes, With Species Accounts, Type Images, And Relevant Literature (Lepidoptera: Nymphalidae), James C. Dunford

Insecta Mundi

A taxonomic overview for the fritillary genus Speyeria Scudder (= Argynnis Fabricius) and its placement within the Heliconiinae (Nymphalidae) is presented. Taxonomic accounts, type images, and relevant literature for the 25 subspecies within the Speyeria atlantis (Edwards) and Speyeria hesperis (Edwards) complexes and the 16 nominate Speyeria species are included. Errors in nomenclature are identified, taxonomic, life history, and distributional information are updated, and type locality information is discussed. Images of primary type specimens for all 16 Speyeria species and the 25 subspecies in the atlantis - hesperis complexes appear together in color here for the first time. One new …

Parallel Shifts In Ecology And Natural Selection In An Island Lizard, Ryan Calsbeek, Wolfgang Buermann, Thomas B. Smith

Dartmouth Scholarship

Natural selection is a potent evolutionary force that shapes phenotypic variation to match ecological conditions. However, we know little about the year-to-year consistency of selection, or how inter-annual variation in ecology shapes adaptive landscapes and ultimately adaptive radiations. Here we combine remote sensing data, field experiments, and a four-year study of natural selection to show that changes in vegetation structure associated with a severe drought altered both habitat use and natural selection in the brown anole, Anolis sagrei.

Results: In natural populations, lizards increased their use of vegetation in wet years and this was correlated with selection on limb length …

Wolf Spiders Of The Pacific Region: The Genus Zoica (Araneae, Lycosidae), Volker W. Framenau, James W. Berry, Joseph A. Beatty

Scholarship and Professional Work - LAS

The wolf spider genus Zoica Simon 1898 is currently known only from the Indo-Australasian region, including India in the west to northern Western Australia and Papua New Guinea in the east. Here we extend the known distribution of the genus into the Pacific region by describing two new species, Z. carolinensis new species from the Caroline Islands, Federated States of Micronesia, and Z. pacifica new species from the Republic of the Marshall Islands.

A Primitive Aphidiine Wasp In Albian Amber From Spain And A Northern Hemisphere Origin For The Subfamily (Hymenoptera: Braconidae: Aphidiinae), Jaime Ortega-Blanco, Daniel J. Bennett, Xavier Delclòs, Michael S. Engel

Faculty Publications

A description of a new genus and species of braconid, Archephedrus stolamissus, from Early Cretaceous (Albian) amber from Moraza-Peñacerrada I (Spain) is here provided. This is the first fossil Aphidiinae described in Cretaceous amber. The fossil has some typical characters of the subfamily but possesses a unique assemblage of characters among aphidiines, such as a fairly robust abdomen, with a more pronounced articulation between the first and second, instead of the second and third, metasomal segments, as well as several wing venational traits. The distribution of this and other aphidiine fossils, as well as their putative phylogenetic placement as …

The examination of entomological collections of cicadas of several Brazilian institutions revealed three undescribed species in the genus Fidicinoides Boulard & Martinelli i.e., F. dolosa sp.n., F. carmenae sp.n. and F. rosabasalae sp.n. They are described and illustrated based on the male genitalia, the right anterior femur and the operculum.

Revision Of The Ant Genus Procryptocerus (Hymenoptera: Formicidae: Myrmicinae: Cephalotini), Francisco Serna

Open Access Theses & Dissertations

Ants of the genus Procryptocerus (Hymenoptera: Formicidae) are characterized by the protrusion of the clypeus forming a broad nasus and antennal scrobes over the eyes. The toruli are located directly posterior to the flanks of the nasus opposite to each other. The vertex is deflexed in most species. I present an in-group comparison of the external morphology focusing on the workers. I also present a general morphology for gynes and males. I analize previously mentioned characters as well as new ones, and clarify their character states in different species. For the metasoma I propose a new system of ant metasomal …

Revision Of The Ant Genus Crematogaster (Hymenoptera: Formicidae) In North America, Cynthia Ellen Morgan

Open Access Theses & Dissertations

The natural history of thirty-eight species of the genus Crematogaster in North America has been discussed and distribution of specimens mapped. A dichotomous key to the workers of these species has been developed. I hypothesized that the species richness is not as great as previously thought in North America. A taxonomic review of these species has been made with the following changes:

Crematogaster cerasi Fitch 1855 senior synonym of C. browni Buren1968.

C. coarctata Mayr 1870 senior synonym of C. californica Emery 1895, C. mormonum

Emery 1895 and C. colei Buren1968.

C. depilis Wheeler 1919 senior synonym of C. larreae …

Taxonomical And Chorological Notes On The Turkish Endemic Scorzonera Amasiana Hausskn. & Bornm. (Asteraceae), Muhi̇tti̇n Di̇nç, Yavuz Bağci

Turkish Journal of Botany

Scorzonera amasiana Hausskn. & Bornm. is a stenoendemic species known from a few localities in Amasya Province. After the rediscovery of S. amasiana, it has been recorded from a new locality in Amasya. Using chorological and ecological data, morphological study of the collected specimens suggest that the recently described Scorzonera ekimii A.Duran is synonymous with S. amasiana. The conservation status of S. amasiana is also reviewed, based on the present distribution data.

Review Of The Ichthyofaunal Changes In Lake Eğirdir Between 1915 And 2007, Fahretti̇n Küçük, Hasan M. Sari, Orhan Demi̇r, İskender Gülle

Turkish Journal of Zoology

The ichthyofaunal changes in Lake Eğirdir between 1915 and 2007 were reviewed. It was understood that the most drastic change in the ichthyofauna of Lake Eğirdir occurred in 1955 with the introduction of pike-perch (Sander lucioperca), and that the process of change continued with the addition of Prussian carp (Carassius gibelio) in 1996 and big scale sand smelt (Atherina boyeri) in 2003. Today, there are 15 fish taxa (10 native, 5 non-native) in Lake Eğirdir. It was determined that, among the endemic species of Lake Eğirdir, Handlirsch^{'}s minnow (Pseudophoxinus handlirschi) is extinct (EX), Ereğli minnow (Hemigrammocapoeta kemali) disappeared, and Eğirdir …
