Morphological Changes Of The Asian Shore Crab Across Latitudes, Ainslee Mcmullin, Blaine D. Griffen

Library/Life Sciences Undergraduate Poster Competition 2022

The Asian shore crab, Hemigrapsus sanguineus , is an invasive species that has rapidly spread across the Eastern United States coastline. First observed in North America in 1988, its range currently extends from Maine to North Carolina. H. sanguineus has adapted very well to this region and has displaced several native species as the dominant crab in rocky intertidal habitats. Although the Asian shore crab’s biology and interactions with native species has been well studied, larger scale impacts (economic, potential further spread, community ecology, etc.) are under researched. We collected specimen samples of H. sanguineus throughout its entire East coast …

Reviewing The Effects Of Human-Induced Limb Damage In Crabs, Jacob B. Spencer, Blaine D. Griffen

Library/Life Sciences Undergraduate Poster Competition 2022

Limb damage in crabs comes in various forms, each with unique consequences. Brachyuran crabs shed limbs as a defensive reflex, with natural breakage occurring along a plane, otherwise known as autotomy. In addition to autotomy, crabs commonly lose limbs due to fishing practices such as declawing. In many areas, taking the limbs and releasing the crab is a common practice. The logic is that the populations won’t decline if the crab is put back. Other practices such as nicking, or cutting the main claw tendon, are used to restrict claw movement. Various effects of these fishery practices have been documented …

Introducing Xanthoria Parietina: Invasive, Naturalized, Or Opportunistic?, Mikele Baugh, Steve Leavitt

Library/Life Sciences Undergraduate Poster Competition 2022

Lichens are one of the world’s ubiquitous group of organisms. They have been documented from frigid tundras to arid deserts. While some species are known to be particularly hardy and flexible in their habitats, many species are linked to specific growing conditions. As the global climate changes, the geographical range for different growing conditions shifts. Economic trade and human travel provide new opportunities for species to access new locations that are beginning to develop habitable conditions. Xanthoria parietina has been observed in the Great Basin (a region outside of its typical coastal distribution) found in newly built horticultural landscapes. Individuals …

Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elaine Lek, Joshua Brown

Fisheries research reports

Due to the species-specific nature of otoliths and given they are often the only part of the fish preserved when fish die, otolith catalogues can be used in numerous applications, such as diet studies in fish eating animals, including pinnipeds, fish and sea birds; archaeological purposes such as reconstructing indigenous people’s diets from otoliths found in middens or evolutionary history of fish species by comparing fossilized otoliths. Given the unique mixture of subtropical and temperate fish, including many endemic species that occur off the southwest corner of WA having a catalogue for this area is extremely important for people working …

Seedling Growth And Soil Chemistry In A Chronosequence Of Forest Restoration From Agriculture, Michaela J. Woods, Sarah J. Frankenberg, Joseph R. Juodvalkis, Mary C. Lloyd, Meredith Cobb, Ryan Mcewan

Five Rivers MetroParks Collaboration Data Archive

Soils were collected from forest restorations that were 0, 7, 10, 50 and 100 years old and assessed for soil nutrients, chemistry, and enzymatic activity. Quercus macrocarpa seedlings were planted in each soil type, after 5 months of growth seedlings were destructively harvested. Seedling mass and the colonization rate of their roots by ectomycorrhizal fungi are reported.

The photo accompanying this data collection is of the researchers' germinating Quercus macrocarpa seeds.

Effects Of Invasional Meltdown On Community Structure In Marine Ecosystems In The Damariscotta Estuary Of Maine, Kate Lazzeri

Student Research Poster Presentations 2021

Basibiont organisms form the foundation of marine ecosystems by providing additional space for new species to settle on as epibionts. Invasive epibionts may take advantage of this new basibiont presence, which leads to many harmful effects on native organisms such as competition for both resources and food. In some cases, invasive species facilitate recruitment of other invasive organisms, a phenomenon referred to as invasional meltdown, but it is not known if invasion of new basibionts increases invasive epibiont occurrence. The purpose of this study is to answer the following research questions: 1) does the invasion status of the basibiont alter …
