Phenotypic Divergence Despite High Levels Of Gene Flow In Galapagos Lava Lizards (Microlophus Albemarlensis), Mark Jordan, H. Snell, H. Snell, W. Jordan

Mark A. Jordan

The extent of evolutionary divergence of phenotypes between habitats is predominantly the result of the balance of differential natural selection and gene flow. Lava lizards (Microlophus albemarlensis) on the small island of Plaza Sur in the Galápagos archipelago inhabit contrasting habitats: dense vegetation on the western end of the island thins rapidly in a transitional area, before becoming absent on the eastern half. Associated with these habitats are phenotypic differences in traits linked to predator avoidance (increased wariness, sprint speed, and endurance in lizards from the sparsely vegetated habitat). This population provides an opportunity to test the hypothesis that reduced …

The Influence Of Historical Landscape Change On Genetic Variation And Population Structure Of A Terrestrial Salamander ( Plethodon Cinereus ), Mark Jordan, Douglas Morris, Scott Gibson

Mark A. Jordan

Forest loss and fragmentation is expected to shape the genetic structure of amphibian populations and reduce genetic variation. Another factor widely understood to have impacted these same parameters in North America is the range expansion that occurred following glacial retreat at the end of the Pleistocene. The Eastern Red-Backed Salamander (Plethodon cinereus) has been subjected to both processes. In this context, we investigated the historical events that are likely to have shaped genetic variation in this species using a panel of six microsatellite markers screened on individuals sampled across ten localities in northeastern Indiana, USA. We found low genetic diversity …

Results Of A Preliminary Shoreline Shellfish Sanitary Survey Near Banjul, Gambia Conducted On 18 June 2011, Kanyi Babanding, Michael A. Rice

Michael A Rice

A preliminary shoreline survey was conducted along the Bund Road (frequently referred to as Bond Road) levee and the Banjul-Serrekunda Highway in the northern Tanbi Wetlands oyster harvesting area in the metropolitan Banjul area. In part this was designed as a training exercise for Gambian officials will be assuming responsibility for future shoreline surveys in the Gambia. Key identified areas of concern include the Banjul fish landing area on Bund Road utilized by a number of artisanal fishers; an over-water toilet facility for fishers near the fish landing site; evidence of illegal waste and rubbish dumping along Bund Road; an …

Description Of The Larva And Female Genitalia Of Trechus Gamae With Data On Its Ecology, Ana Reboleira, Vicente Ortuño

Ana Sofia P.S. Reboleira

The third instar larva and the female genitalia of Trechus gamae Reboleira et Serrano (Coleoptera Carabidae Trechini) are described, illustrated and commented. Larvae and imagos were collected in deep parts of caves from Estremenho karstic massif in the centre Portugal. The work provides the first study on hypogean beetle larvae from Portugal, increasing the knowledge about hypogean microendemic species from the Lusitanic district of the Iberian Peninsula. The morphological diagnostic characters of the female genitalia corroborate the inclusion of T. gamae in the “T. fulvus-group”. Some new data on the ecology of this species are also given.

Carbohydrate Response Element Binding-Protein Is Activated By Elevated Glucose Levels In The Normal Murine Liver Cell Line Nmuli, Jackson Adams, Daniel G. Peterson

Daniel G. Peterson

Carbohydrate response element (ChRE) binding protein (ChREBP) is a transcription factor that is regulated by intracellular glucose levels and activates several lipogenic genes including acetyl CoA carboxylase (ACC). Previous studies of the ChREBP system have used both in vivo models as well as isolated primary hepatocytes. Due to the difficulties in isolation and genetic variability of primary cell culture, we propose the use of a normal murine liver cell line (NMuLi) as a convenient alternative to primary isolated hepatocytes. We show that high (25 mM) but not low (0.5 or 5 mM) glucose activates a luciferase reporter driven by 4 …

North American Pollinator Partnership Conference: Making A Difference One Pollinator At A Time, Tammy Horn

Tammy Horn

The North American Pollinator Protection Campaign 10th Anniversary conference, held in Washington DC 2010, is the last place I saw myself being invited to a couple of years ago. Unemployed and changing careers, I withdrew from conventional academe to work bees on surface mine sites in Kentucky, which are not conventional places to define new careers.

High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt.

Paul F. Eschenfelder

Commercial aircraft are capable of, and in fact, do, operate at high speed (>250 knots indicated airspeed [KIAS]) at low altitude (below 10,000’ above ground level) worldwide. Design, construction and certification standards for these aircraft were developed over 40 years ago. Since the development of these standards populations of large flocking birds have increased dramatically in many parts of the world. Yet neither design/construction standards nor operational practice have changed to reflect the new threat. Subsequent serious damage resulting from recent collisions indicates change is necessary. Since 2003, flight rules in Canada and the United States have been amended, …

Integrating Avian Radar Into The Aviation Operating Environment, Richard Sowden, Paul Eschenfelder

Paul F. Eschenfelder

Avian radar technology has matured to the point where robust data and analysis tools are now able to provide the aviation industry with high quality information to support bird strike risk mitigation activities. The aviation operating environment is dynamic and challenging with complex interactions between the primary bird strike risk mitigation stakeholders; airport operators, air traffic service providers and flight crews. The transfer of this proof of concept technology into a suite of tools that is integrated into the aviation industry requires the engagement and support of the user community in the next critical evolutionary step of this emerging technology. …

Conservation Genetics Of The Endangered Eastern Freshwater Cod, Maccullochella Ikei, Catherine Jane Nock

Dr Catherine J Nock

Fragmentation over evolutionary time scales following vicariant and dispersal events has long been recognised as a dominant process in biological diversification and speciation; while anthropogenic habitat fragmentation in recent times is considered a threat to the long-term persistence of species and ecosystems. The eastern freshwater cod Maccullochella ikei is Australia’s largest endangered freshwater fish species. Abundant in the Clarence and Richmond River systems at the time of European settlement, populations crashed in the early 1900s causing local extinctions and range reduction. Recovery efforts, including a prohibition on fishing for M. ikei and hatchery breeding programs, were initiated in an attempt …

Intracellular Invasion Of Green Algae In A Salamander Host, Ryan Kerney, Eunsoo Kim, Roger Hangater, Aaron Heiss, Cory Bishop, Brian Hall

Ryan Kerney

The association between embryos of the spotted salamander (Ambystoma maculatum) and green algae (“Oophila amblystomatis” Lamber ex Printz) has been considered an ectosymbiotic mutualism. We show here, however, that this symbiosis is more intimate than previously reported. A combination of imaging and algal 18S rDNA amplification reveals algal invasion of embryonic salamander tissues and cells during development. Algal cells are detectable from embryonic and larval Stages 26–44 through chlorophyll autofluorescence and algal 18S rDNA amplification. Algal cell ultrastructure indicates both degradation and putative encystment during the process of tissue and cellular invasion. Fewer algal cells were detected in later-stage larvae …

Symbioses Between Salamander Embryos And Green Algae, Ryan Kerney

Ryan Kerney

The symbiosis between Ambystoma maculatum (spotted salamander) embryos and green algae was initially described over 120 years ago. Algae populate the egg capsules that surround individual A. maculatum embryos, giving the intracapsular fluid a characteristic green hue. Early work established this symbiosis to be a mutualism, while subsequent studies sought to identify the material benefits of this association to both symbiont and host. These studies have shown that salamander embryos benefit from increased oxygen concentrations provided by their symbiotic algae. The algae, in turn, may benefit from ammonia excreted by the embryos. All of these early studies considered the associ- …
