Next-Generation Field Guides, Elizabeth J. Farnsworth, Miyoko Chu, W. John Kress, Amanda K. Neill, Jason H. Best, John Pickering, Robert D. Stevenson, Gregory W. Courtney, John K. Vandyk, Aaron M. Ellison

John K. VanDyk

To conserve species, we must first identify them. Field researchers, land managers, educators, and citizen scientists need up-to-date and accessible tools to identify organisms, organize data, and share observations. Emerging technologies complement traditional, book-form field guides by providing users with a wealth of multimedia data. We review technical innovations of next-generation field guides, including Web-based and stand-alone applications, interactive multiple-access keys, visual-recognition software adapted to identify organisms, species checklists that can be customized to particular sites, online communities in which people share species observations, and the use of crowdsourced data to refine machine-based identification algorithms. Next-generation field guides are user …

In the future, this research suggests that designing highways and cars with features built into the structures of the roads themselves that implicitly influence typical drivers to achieve better fuel economy without making an active effort. These types of “intuitively” fuel efficient highways and cars are proposed, defined and modeled within the scope of this paper.

Cholinergic Transmission During Nicotine Withdrawal Is Influenced By Age And Pre-Exposure To Nicotine: Implications For Teenage Smoking, Laura O'Dell

Laura Elena O'Dell

Adolescence is a unique period of development characterized by enhanced tobacco use and long-term vulnerability to neurochemical changes produced by adolescent nicotine exposure. In order to understand the underlying mechanisms that contribute to developmental differences in tobacco use, this study compared changes in cholinergic transmission produced by exposure to nicotine and withdrawal from nicotine in rats of different ages, some of which had exposure to nicotine as adolescents. The first study compared extracellular levels of acetylcholine (ACh) in the nucleus accumbens (NAcc) during nicotine withdrawal in adolescent, adult and adult rats that were exposed to nicotine during adolescence. Adolescent (PND …

Insulin-Resistant Rats Display Enhanced Nicotine Reward Following A High-Fat Diet Regimen., Laura O'Dell

Laura Elena O'Dell

Tobacco use among persons displaying type II diabetes exponentially increases negative health consequences and mortality rates. Especially troubling, diabetic persons who smoke display reduced rates of tobacco cessation as compared to non-diabetic smokers. Diabetes is a metabolic syndrome that consists of insulin resistance due to disruptions in insulin signaling. Insulin has been shown to modulate mesolimbic reward circuitry in response to drugs of abuse, such as nicotine. This study utilized the conditioned place preference paradigm (CPP) to examine nicotine reward in a rat model of insulin resistance induced by the consumption of a high-fat diet (HFD). Rats were placed on …

What Can We Learn From Confusing Olivella Columellaris And O. Semistriata (Olivellidae, Gastropoda), Two Key Species In Panamic Sandy Beach Ecosystems?, Alison I. Troost, Samantha D. Rupert, Ariel Z. Cyrus, Frank V. Paladino, Benjamin F. Dattilo, Winfried S. Peters

Benjamin F. Dattilo

Abstract: Olivella columellaris (Sowerby 1825) and O. semistriata (Gray 1839) are suspension-feeding, swash-surfing snails on tropical sandy beaches of the east Pacific. While they often are the numerically dominant macrofaunal element in their habitats, their biology is poorly understood; the two species actually have been confused in all of the few publications that address their ecology. Frequent misidentifications in publications and collections contributed also to an overestimation of the geographic overlap of the two species. To provide a sound taxonomic basis for further functional, ecological, and evolutionary investigations, we evaluated the validity of diagnostic traits in wild populations and museum …

A Revision Of The Genus Kaszabister Mazur (Histeridae, Histerinae, Exosternini), Michael S. Caterino, Nicolas Degalllier, Slawomir Mazur, Alexey K. Tishechkin

Michael S Caterino

We revise the four species of Kaszabister Mazur, 1972, one of which, Kaszabister barrigai sp. n., is described as new. The other species in the genus are K. rubellus (Erichson, 1834), K. ferrugineus (Kirsch, 1873) and K. carinatus (Lewis, 1888). The species are principally known from the subtropics of South America, with one in Central America. Lectotypes are designated for K. rubellus and K. ferrugineus, and a key is provided for all the species. Ants of the genus Solenopsis Westwood, mainly S. invicta Buren and S. saevissima (Smith), are documented as hosts of three of the four species.

Seven New Species Of Cephennium Muller & Kunze (Coleptera, Staphylinidae, Scymaeninae, Cephenniini) From California With A Key To Native North American Species, Michael S. Caterino, Katie J. Hopp

The Platycerus (Coleoptera, Lucanidae) Of California, With The Recognition Of Platycerus Cribripennis Van Dyke As A Valid Species, Michael S. Caterino, M J. Paulson

Michael S Caterino

Th e status of Platycerus cribripennis Van Dyke, generally treated as a synonym of P. marginalis Casey, has been unclear. Here we recognize and redescribe P. cribripennis, which is endemic to the coastal mountains of California, as a valid species due to its unique morphology. A key to the Platycerus of California is presented, and the distributions of the recognized species are discussed.
