Importance Of Forest Structure For Amphibian Occupancy In North-Central Florida: Comparisons Of Naturally Regenerated Forests With Planted Pine Stands, Christopher J E Haggerty

USF Tampa Graduate Theses and Dissertations

Once dominant, longleaf pine forests of the southeastern United States have been modified by 97 percent, resulting in several animal species being listed as endangered and threatened. Pine plantation silviculture (tree plantings) now occupies half of the original longleaf range where several animal species of conservation concern have experienced recent local population declines. In North America, the accepted practice of pine plantations is to plant pines densely in rows for wood production. Given that land use is considered a primary local driver for the 30% of amphibian species currently at risk of extinction, and planted pine is predicted to expand …

A New Species Of Psalidognathus Gray, 1831 From Peru (Coleoptera: Cerambycidae: Prioninae), Taketsune Noguchi, Antonio Santos-Silva

Insecta Mundi

Psalidognathus antonkozlovi (Coleoptera: Cerambycidae: Prioninae), a new species from Peru, is described and illustrated. The new species is included in a previous key.

Currently, Psalidognathus Gray, 1831 encompasses 10 species distributed from Costa Rica to northern South America (Monné 2016). The species can be included in two groups: the “modestus” group, species without a spine at the apex of the basal antennomeres; and the “friendii” group, species with a spine at the apex of the basal antennomeres. Santos-Silva and Komiya (2012) published a provisional study of the species of the “modestus” group, considering seven species in it. The key to …

Annotated Checklist And Biogeographic Composition Of The Lycaenidae (Lepidoptera) Of Trinidad, West Indies, Matthew Cock, Robert K. Robbins

Insecta Mundi

A revised annotated checklist for the butterfl y family Lycaenidae (Lepidoptera) of Trinidad is presented, updating nomenclature, and indicating synonyms from earlier lists and papers. The checklist includes 131 species of Lycaenidae, comprising 127 species of 49 genera of Eumaeini, Theclinae, and four species of three genera of Polyommatinae. There are more than 30 new island records. No lycaenid species is endemic to Trinidad, and the fauna consists primarily of widespread species (71%) that occur from Central America to the Amazon Basin. However, the primary biogeographic affi nity is the Amazon Region, where 94% of the Trinidad lycaenid fauna also …

Parajulid Milliped Studies Xi: Initial Assessment Of The Tribe Gosiulini (Diplopoda: Julida), Rowland M. Shelley, Jamie M. Smith

Insecta Mundi

The parajulid milliped tribe Gosiulini (Diplopoda: Julida) comprises two genera – Gosiulus Chamberlin, with three projections on the posterior gonopod and two species in the southcentral/southwestern United States (US) [Arizona, Colorado, New Mexico, and Texas], and monotypic Minutissimiulus Shelley, n. gen., with two projections, in Nuevo León, Mexico. Gosiulus conformatus Chamberlin occupies the plains/fl atlands of Texas, while its congener inhabits high elevations to the west in all four US states. Both are anticipated in Mexico (Coahuila, Chihuahua, and Sonora), and G. conformatus is expected in southeastern Colorado, eastern New Mexico, and the Oklahoma panhandle. The eastern boundary …

The Archaeopalynology Of Crystal River Site (8ci1), Citrus County, Florida, Kendal Jackson

USF Tampa Graduate Theses and Dissertations

The Woodland-period (ca. 1000 B.C. to A.D. 1050) fisher-hunter-gatherers of the Crystal River drainage on Florida’s Big Bend Coast are well known among southeastern archaeologists for their elaborate shell mound architecture, maritime lifeway, and exotic exchange goods. Recent archaeological investigations at the Crystal River site have employed high-resolution topographic mapping, geophysical surveys, trench excavations, and coring to model the temporality of mound construction and occupation at the site; this work has set the stage for subsequent research focusing on community structure, resource extraction, and human-ecosystem dynamics. However, like many central and north peninsular Gulf Coast sites, our understanding of Crystal …

Feeding Patterns And Trophic Food Web Dynamics Of Armases Cinereum Across A Mangrove/Upland Ecotone, Erin Paige Kiskaddon

USF Tampa Graduate Theses and Dissertations

The feeding ecology of a common saltmarsh crab, Armases cinereum (Armases), was investigated to determine how habitat (mangrove vs. ecotone, natural mangrove vs. modified mangrove fringe) influenced this species’ feeding behavior and trophic ecology in its southwestern Florida, USA, distribution. In the laboratory, Armases’ preference for mangrove material was examined using leaves of three mangrove species (Avicennia germinans, Laguncularia racemosa, and Rhizophora mangle) and leaves of different degradation levels (fresh, senescent, and partially-decomposed). Leaf material from A. germinans was preferentially consumed over the other taxa at fresh and partially-decomposed levels of leaf decay. When Armases were …

The Evolution Of Line-1 In Vertebrates, Stephane Boissinot, Akash Sookdeo

Publications and Research

The abundance and diversity of the LINE-1 (L1) retrotransposon differ greatly among vertebrates. Mammalian genomes contain hundreds of thousands L1s that have accumulated since the origin of mammals. A single group of very similar elements is active at a time in mammals, thus a single lineage of active families has evolved in this group. In contrast, non-mammalian genomes (fish, amphibians, reptiles) harbor a large diversity of concurrently transposing families, which are all represented by very small number of recently inserted copies. Why the pattern of diversity and abundance of L1 is so different among vertebrates remains unknown. To address this …

A New Species Of Centruroides (Scorpiones: Buthidae) From Quiché, Northwestern Guatemala, Rony E. Trujillo, Luis F. De Armas

Euscorpius

A new species of the genus Centruroides Marx, 1890 is described from Sotzil Village (15.61775°N, -91.09745°W, 1173 m a.s.l.), Chajul Municipality, Quiché Department, Guatemala, on basis of one female and one male. It closely resembles Centruroides caral Armas et Trujillo, 2013 from northeastern Guatemala (240 Km southeast of Chajul), but male differs by having a most globose pedipalp manus, as well as metasoma clearly more attenuate (len-gth/width ratio: segments II–IV = 2.4, 2.7 and 1.4, respectively; 1.7, 2.2 and 2.5 in the holotype of C. caral, the only known specimen of this taxon). Data on its habitat and some …

Reproductive Schedule Of The Silver Shiner (Notropis Photogenis) In The Flint River Of Alabama, Kelly Hodgskins, Stephanie Greenleaf, Jonathan Hillman, Bruce Stallsmith

Southeastern Fishes Council Proceedings

Many river-dwelling species of fish are dependent upon and stimulated by fluctuations in river flow for successful reproduction. This is especially true of pelagophils, a reproductive guild whose eggs and larvae require free drifting on river currents for several days. Notropis photogenis (Silver Shiner) is a rheophilic species with a broad distribution from Ontario to the southeastern United States including northern tributaries to the Tennessee River in Alabama. Little is known of its reproductive biology. The purpose of this study was to describe aspects of reproductive biology such as timing and pattern of ovarian development and oocyte maturation of N. …

Consciousness And The Unity Of Mind, Mark Rowlands

Animal Sentience

Several types of objection have been raised against the arguments I presented in my target article, “Are animals persons?” Among the objections are the following: (1) the claim that animals are persons is of little significance, (2) my use of the Lockean conception of the person is questionable, (3) whether a creature qualifies as a person is a matter of social construction rather than objective fact, (4) reflective consciousness is more important than I realize, (5) my reliance on implicit self-awareness in the account of personhood is ill-advised, (6) my account entails that too many creatures qualify as persons, and …

The North American Sea Ducks: Their Biology And Behavior, Paul A. Johnsgard

Zea E-Books Collection

The 21 species of sea ducks are one of the larger subgroups (Tribe Mergini) of the waterfowl family Anatidae, and the 16 species (one historically extinct) that are native to North America represent the largest number to be found on any continent, and also the largest number of endemic sea duck species native to any continent.

Although generally not important as game birds, the sea ducks include some economically important birds such as the eiders, the basis for the Arctic eiderdown industry and a historically important food source for some Native American cultures. They also include what is probably the …

Insects: Still Looking Like Zombies, Christopher S. Hill

Animal Sentience

In arguing that insect brains are capable of sentience, Klein & Barron rely heavily on Bjorn Merker’s claim that activity in the human mid-brain is sufficient for conscious experience. I criticize Merker’s claim by pointing out that the behaviors supported by midbrain activity are much more primitive than the ones that appear to depend on consciousness. I raise a similar objection to Klein & Barron’s contention that insect behaviors are similar to behaviors that manifest consciousness in human beings. The similarity is weak. I also respond to the related view that integrative activity in mid-brain structures is sufficient to explain …

Mitochondrial Dna Sequence And Lack Of Response To Anoxia In The Annual Killifish Austrofundulus Limnaeus, Josiah Tad Wagner, Florisela Herrejon Chavez, Jason E. Podrabsky

Center for Life in Extreme Environments Publications

The annual killifish Austrofundulus limnaeus inhabits ephemeral ponds in regions of Venezuela, South America. Permanent populations of A. limnaeus are maintained by production of stress-tolerant embryos that are able to persist in the desiccated sediment. Previous work has demonstrated that A. limnaeus have a remarkable ability to tolerate extended periods of anoxia and desiccating conditions. After considering temperature, A. limnaeus embryos have the highest known tolerance to anoxia when compared to any other vertebrate yet studied. Oxygen is completely essential for the process of oxidative phosphorylation by mitochondria, the intracellular organelle responsible for the majority of adenosine triphosphate production. Thus, …

Lessons From The Far End: Caterpillar Frass-Induced Defenses In Maize, Rice, Cabbage, And Tomato, Swayamjit Ray, Saumik Basu, Loren J. Rivera-Vega, Flor E. Acevedo, Joe Louis, Gary W. Felton, Dawn S. Luthe

Department of Entomology: Faculty Publications

Plant defenses to insect herbivores have been studied in response to several insect behaviors on plants such as feeding, crawling, and oviposition. However, we have only scratched the surface about how insect feces induce plant defenses. In this study, we measured frass-induced plant defenses in maize, rice, cabbage, and tomato by chewing herbivores such as European corn borer (ECB), fall armyworm (FAW), cabbage looper (CL), and tomato fruit worm (TFW). We observed that caterpillar frass induced plant defenses are specific to each host-herbivore system, and they may induce herbivore or pathogen defense responses in the host plant depending on the …
