Species Speciation

Biological diversity results from speciation, which generally involves the splitting of an ancestral species into descendant species due to adaptation to different niches or the evolution of reproductive incompatibilities (Coyne and Orr 2004). The diverse flora and fauna of the world, including the native inhabitants of the Greater Yellowstone Area (GYA), exist as a result of the speciation process. The central role speciation plays in generating biological diversity imbues importance to our understanding of this process. The general importance of a thorough understanding of speciation is amplified because of the current high rates of extinction on the planet. This is because a long term solution to the present extinction crisis will require maintaining the processes that create species (speciation) not simply preventing extinction. However, many central questions regarding speciation remain to be answered. One fundamental question in speciation research is whether diverging species are isolated (i.e., prevented from interbreeding) due to differences in one, a few, or many characters and whether each of these character differences results from different alleles at a few or many genes. For example, speciation and reproductive isolation might involve divergence along multiple phenotypic axes, such as mate preference, habitat use or preference, and phenology (the timing of life-cycle events). Alternatively, isolation could result from differentiation of a single character. I propose to address this question by assessing patterns of variation for a suite of characters across a hybrid zone between two butterfly species. This is possible because patterns of character variation across hybrids zones allow for inferences about reproductive isolation (Barton and Hewitt 1985).

Jackson Hole, the Teton Range and the Yellowstone Country are perhaps unmatched in alpine beauty. Millions of Americans yearly draw inspiration and renewal through visiting this diverse region of nature's splendors unsurpassed. Yet the region was among the last to be revealed to the American people. Certainly not because the region is uninteresting. On the contrary, it represents one of the most geologically intriguing and scenically compelling lands within America. No, the region was unknown for more practical reasons. It was hundreds of miles distant from the primary immigrant routes across the nation. No significant mineral strikes provided "instant urbanization." Not even pioneer farmers or cattlemen found the region attractive. Altitude, deep snows, shallow soil, and a short growing combined to discourage farmers. Ranchers did better but struggled during the long winters. Even the timber was classed inferior. Lodgepole Pine trees of marginal commercial worth carpeted the hills. Lumbermen found opportunity further west, amongst the mist and fog-shrouded coastal ranges of the Pacific Slope. In short, aside from scenery and some rather bizarre geothermal activity, there was little attraction to the Greater Yellowstone area, and no reason for settlement.

Natural fires are common in coniferous forests in the Rocky Mountains, and one of the largest fires in recent history occurred in the Greater Yellowstone Area (GYA) in 1988 when over a million acres of lodgepole pine (Pinus contorta), subalpine fir (Abies lasiocarpa) and Engelmann spruce (Picea engelmannii) burned. In the summers of 1989, 1990 and 1991 and again in 1997 and 1998, we trapped small mammals in two burned and two adjacent unburned forests in the Huckleberry Mountain fire in the Rockefeller Memorial Parkway, 0.5 km north of Grand Teton National Park (GTNP). Here we report on the captures and recaptures of the two most common species of small mammals, the deer mouse (Peromyscus maniculatus) and the southern red-backed vole (Clethrionomys gapperi); and analyze retrapping frequency for each species in the burned and unburned forest. Our intent was to test the hypothesis that the probability of recapture is the same for both species in burned and unburned habitats. These capture/recapture data will be used by other co-investigators in additional publications to report on estimated population sizes and microhabitat associations.

New Zealand Mud Snail

Invasive species are one of the top two threats to native biodiversity worldwide (Mack et al. 2000). A primary goal of invasion biology is to predict which introduced species become invasive, or reach pest status, and which systems are susceptible to invasion (Heger and Trepl 2003). In order to complete this goal, it is vital to understand long-term dynamics of invasive species populations and their interactions with native communities in their introduced range. Most studies of invasions by non-native species are not extensive enough to determine long-term effects on the native systems (Strayer 2010). The first objective of this study is to determine the long-term abundance and biomass of the New Zealand mud snail, (Potamopyrgus antipodarum), in the Greater Yellowstone Area (GYA). The second objective is to analyze the long-term effects of P. antipodarum on the biomass, abundance, and taxon diversity of native benthic invertebrate assemblages in the GYA. The ten-year span of data available for P. antipodarum and the native macroinvertebrate communities at Lower Polecat Creek in Grand Teton National Park and the Gibbon and Firehole Rivers in Yellowstone National Park provide a unique opportunity to study the macroinvertebrate community succession over time. Data from the proposed macroinvertebrate community survey in the summer of 2011 will be compiled with previous surveys from 2001-2009 to evaluate the long-term changes in the macroinvertebrate community at Polecat Creek and the Gibbon and Firehole Rivers.
