Recommendations For Establishing A Market For Invasive Green Crabs In New England, Eve Fischer, Jesse Minor, Marissa Mcmahan
Recommendations For Establishing A Market For Invasive Green Crabs In New England, Eve Fischer, Jesse Minor, Marissa Mcmahan
Student Scholarship
Green crabs are one of the most invasive marine species in the world. Their populations in New England have grown significantly due to climate change, increasing their environmental and socioeconomic impacts. Green crabs are voracious predators of soft shell clams, and have had a detrimental impact on the region’s valuable clam fisheries. They also prey on juvenile lobsters and other shellfish and compete with native crab species for resources. Green crabs burrow into and damage eelgrass beds, which are a vital habitat for many marine species and an important “blue carbon” sink. Due to their rapid rate of reproduction as …

The tortoise beetle, Cassida sphaerula Boheman, 1854 (Coleoptera: Chrysomelidae: Cassidinae: Cassidini) is endemic to South Africa. Its endemic host, Arctotheca prostrata (Salisb.) Britten (Asteraceae) has been introduced in other countries where it is becoming invasive. Cassida sphaerula could provide a potential biocontrol of Arctotheca weeds as it spends the entire life cycle on this host. An intensive field study, with rearing, photography, and short films of C. sphaerula was conducted in its native habitat to document the life cycle. A checklist of Cassidinae genera in South Africa, along with 19 new host records for Cassidini species in South Africa are …
Whiteflies (Hemiptera: Aleyrodidae) Intercepted On Plant Product Imported To South Korea From 2013–2021, Suhyeon Lee, Soo-Jung Suh
Whiteflies (Hemiptera: Aleyrodidae) Intercepted On Plant Product Imported To South Korea From 2013–2021, Suhyeon Lee, Soo-Jung Suh
Insecta Mundi
Current globalization and technological progress has facilitated and increased the international trade of plant products worldwide and has promoted the long-distance movement of immobile sucking pests such as whiteflies attached on plants. Therefore, being able to compile and update information on intercepted insect pests will help to improve the inspection procedures, to detect, identify and mitigate the damage caused by exotic invasive pests. Records of whiteflies (Hemiptera: Aleyrodidae) intercepted on import plants from 2013 to 2021 in the Pest Information System (PIS) database of South Korea were analyzed. A total of 32 species belonging to 19 genera were intercepted on …

Identification Of A Potential Pathway Of The Exotic Black Weevil (Coleoptera: Curculionidae) In South Korea, Sohee Kim, Seon Woo Lee, Soo-Jung Suh
Identification Of A Potential Pathway Of The Exotic Black Weevil (Coleoptera: Curculionidae) In South Korea, Sohee Kim, Seon Woo Lee, Soo-Jung Suh
Insecta Mundi
The black weevil, Aclees taiwanensis Kôno (Coleoptera: Curculionidae), is one of the primary pests of fig trees in southeastern Asia and southern Europe. Thought to be of subtropical and tropical Asian origin, including China, the weevil was first found in southern areas of South Korea in July 2020. Subsequently, it was found in the following five cities: Haenam, Hampyeong, Jindo, Sinan, and Tongyeong (RDA 2020). Attempts to trace a possible pathway for the exotic black weevil suggested that this species probably followed pathways of illegal importation of infested plants from Taiwan and was unintentionally introduced into South Korea based on …

gars and to engine and flight surfaces of moored aircraft. We questioned whether consistent removal of nest material would negatively affect use of a nest site, measured by a reduction in material accumulation. We conducted our study on a 2,200-ha site in Erie County, Ohio, USA (41° 22’ N, 82° 41’ W), from April 15 through June 2, 2020. We used 120 wooden nest boxes on utility poles, protected by an aluminum predator guard below the box. Our treatments included (1) twice weekly, repeated nest material removal (RMR; n = 40 nest boxes); (2) complete nest removal, but only after …
Non-Native Non-Apis Bees Are More Abundant On Non-Native Versus Native Flowering Woody Landscape Plants, Daniel A. Potter, Bernadette M. Mach
Non-Native Non-Apis Bees Are More Abundant On Non-Native Versus Native Flowering Woody Landscape Plants, Daniel A. Potter, Bernadette M. Mach
Entomology Faculty Publications
Urban ecosystems can support diverse communities of wild native bees. Because bloom times are conserved by geographic origin, incorporating some non-invasive non-native plants in urban landscapes can extend the flowering season and help support bees and other pollinators during periods when floral resources from native plants are limiting. A caveat, though, is the possibility that non-native plants might disproportionately host non-native, potentially invasive bee species. We tested that hypothesis by identifying all non-native bees among 11,275 total bees previously collected from 45 species of flowering woody landscape plants across 213 urban sites. Honey bees, Apis mellifera L., accounted for 22% …

Dispersal drives invasion dynamics of nonnative species and pathogens. Applying knowledge of dispersal to optimize the management of invasions can mean the difference between a failed and a successful control program and dramatically improve the return on investment of control efforts. A common approach to identifying optimal management solutions for invasions is to optimize dynamic spatial models that incorporate dispersal. Optimizing these spatial models can be very challenging because the interaction of time, space, and uncertainty rapidly amplifies the number of dimensions being considered. Addressing such problems requires advances in and the integration of techniques from multiple fields, including ecology, …

Invasive Crayfish Faxonius Rusticus Do Not Prefer Pheromones Of Conspecifics, Michelle Yohe
Invasive Crayfish Faxonius Rusticus Do Not Prefer Pheromones Of Conspecifics, Michelle Yohe
Biology: Student Scholarship & Creative Works
The invasive crayfish Faxonius rusticus has invaded multiple watersheds throughout Pennsylvania and the country. Current trapping methods are time consuming, labor intensive, and ineffective. Because crustaceans produce and utilize pheromones to communicate social status and mating condition, baited pheromone traps might serve as an effective alternative to the current trapping methods. The aim of this study was to examine if F. rusticus can distinguish between pheromones produced by conspecifics during breeding and non-breeding seasons. Previous research in our lab showed that during the breeding season females prefer male pheromones, but that preference disappears during the non-breeding season. We collected pheromones …

New Records Of Digenetic Trematodes Infecting Melanoides Tuberculata (O.F. Müller, 1774) In Florida, Usa, Lori R. Tolley-Jordan, Michael A. Chadwick, Jimmy K. Triplett
Research, Publications & Creative Work
Melanoides tuberculata is a well-known invasive, freshwater snail and intermediate host for many species of parasitic trematodes. Despite being well established in Florida’s freshwater systems, little work has been conducted to document the associated trematodes of the snails. Live snails were collected from 11 sites from 25 locations sampled across the state of Florida, USA of which individuals from six sites were found to be infected with trematodes. Gross morphological characters and phylogenetic analysis using 18S rRNA and ITS2 gene regions, were used to identify these trematode taxa. Snails infected with the gill flukes, Centrocestus formosanus and Haplorchis pumilio (Heterophyidae) …

Small Indian mongooses are detrimental introduced predators in the United States, where they depredate native species, serve as vector of disease, and threaten public safety. Due to the risk of accidental introduction to mongoose-free islands, high cost and limitations to trapping, and no national (Section 3) Environmental Protection Agency (EPA)-registered toxicants for mongoose control, there is a need for an efficacious toxic bait for mongooses for use in conservation areas and at points of entry in the United States. Over the last five years, the National Wildlife Research Center (NWRC) worked to develop a toxic bait for mongooses for registration …

Invasive wild pigs are widely known to cause damage to agricultural properties and commodities, but less has been reported about damages to other types of property. A survey was distributed to golf courses and cemeteries across Texas to explore the extent of damage these properties experience. While both property types reported significant damages, golf courses were found to experience more damage than cemeteries. Using average reported costs and predicted county-level damage, total costs for all golf courses and cemeteries across the state were estimated to exceed $1.6 million USD per year.
Changes In The Zooplankton Community In Barren River Lake (South Central Ky) Between 2008 And 2020, Laurel Philpott
Changes In The Zooplankton Community In Barren River Lake (South Central Ky) Between 2008 And 2020, Laurel Philpott
Mahurin Honors College Capstone Experience/Thesis Projects
Zooplankton are small aquatic animals that serve an important role in transferring energy from phytoplankton to higher trophic levels. The zooplankton community composition in Barren River Lake from 2008 and 2020 was compared. A field study was conducted to not only describe the seasonal population dynamics of zooplankton in Barren River Lake, but also to determine if an invasive zooplankton, Daphnia lumholtzi, was present. While D. lumholtzi was found throughout Barren River Lake in 2008, it was absent from both resampled sites in 2019 and 2020. This, along with erratic patterns of emergence in several other zooplankton species, indicates …

Biology Faculty Scholarship
Climate change and invasive species threaten many ecosystems, including surface freshwater systems. Increasing temperatures and reduced hydroperiod due to climate change may promote the persistence of invasive species and facilitate new invasions due to potentially higher tolerance to environmental stress in successful invaders. Amphibians demonstrate high levels of plasticity in life history characteristics, particularly those species which inhabit both ephemeral and permanent water bodies. We tested the influence of two projected effects of climate change (increased temperature and reduced hydroperiod) on Pacific chorus frog (Pseudacris regilla) tadpoles alone and in combination with the presence of tadpoles of a …
