Variability In Epifaunal Assemblages Between Sargassum Muticum And Zostera Marina: A Functional Group Approach, Jenny Hickman Dec 2021

Variability In Epifaunal Assemblages Between Sargassum Muticum And Zostera Marina: A Functional Group Approach, Jenny Hickman

The Plymouth Student Scientist

Marine macrophytes are globally important to coastal ecosystems, providing refugia, nutrients and important ecological processes. The structure and composition of macrophytes have a bottom-up effect on the epifauna they support. Due to their wide-reaching effects, invasive algae are considered one of the greatest threats facing marine ecosystems. Sargassum muticum is a Japanese algae increasing its non-native range in coastal habitats globally. A highly dispersive algae, able to colonise soft substratum, it is considered a threat to seagrass beds across the North East Atlantic. In Salcombe Estuary, Devon, beds of Zostera marina have seen increasing levels of invasion by S. muticum. …

Geocaching: A New Instructional Tool For Natural Resources Extension And Outreach, Jacob Smith, Dave Coyle, John Thomason, Todd Matthews, John J. Riggins

The Journal of Extension

Nonnative pests and pathogens severely affect forest health and are often spread in firewood. Our objectives were to create an extension education program using “Don’t Move Firewood”-themed geocaches and travel bugs which were placed near campgrounds across Mississippi, and to assess the efficiency and effectiveness of this outreach method. Interactions with caches and travel bugs were monitored over nearly one year and summarized to provide a measure of outreach success. With a one-time per-unit cost of $45.95 for caches and $6.75 for travel bugs, these tools provide ongoing, cost-effective educational approaches well suited to augment existing or launch new outreach …


Interspersed Denuded Zone (Idz): How Patchy Leaf Litter Dynamics In A Buckthorn-Invaded Urban Woodland Can Affect Microarthropod Species Richness, Angela Stenberg Aug 2021

Interspersed Denuded Zone (Idz): How Patchy Leaf Litter Dynamics In A Buckthorn-Invaded Urban Woodland Can Affect Microarthropod Species Richness, Angela Stenberg

DePaul Discoveries

Biodiversity loss may serve as a key diagnostic of the Anthropocene. An important driver of this loss is by means of invasive species. In this study of a forest preserve in Chicago, Illinois we examined Interspersed Denuded Zones (IDZs for short), which are areas of patchy leaf litter in invaded forests caused in this case by the rapid decomposition of litter from buckthorn (Rhamnus cathartica). We characterized the leaf litter mass in IDZs and enumerated litter-inhabiting microarthropod populations. We found that plots of high buckthorn density are associated with IDZs: there was significantly less leaf litter mass in …

A Profile Of Wild Pig Hunters In Texas, Usa, Rachael L. Connally, Maureen G. Frank, Gary E. Briers, Nova J. Silvy, Keith M. Carlisle, John M. Tomeček

Human–Wildlife Interactions

Wild pigs (Sus scrofa) are a widespread exotic, invasive species that poses ecological, agricultural, and human health risks in invaded areas. Wildlife managers often manage wild pig abundance and expansion to mitigate these risks. The diversity of stakeholders involved in the issue of wild pig management complicates efforts to manage the species, and, to be successful, wildlife professionals should consider the human dimensions associated with wild pig management. The prevalence of privately owned lands in Texas, USA necessitates cooperation to enact effective management policies. In this study, we investigate the factors that affect a hunter’s likelihood to participate …

Habitat Use And Movements Of Feral Mallards (Anas Platyrhynchos) And Invasive Muscovy Ducks (Cairina Moschata) In Tampa, Florida, Joni Downs, Mehrdad Vaziri, Lucy Deba Enomah, Zachary J. Smith

Florida Field Naturalist

Feral Mallards (Anas platyrhynchos) and invasive Muscovy Ducks (Cairina moschata) are common waterfowl in urban areas in many parts of the world, though relatively little is known about their habits and movements. This study quantified the fine-scale movements and habitat-use patterns of feral Mallards and Muscovy Ducks in an urban area of Tampa, Florida, from hour-long observational and tracking data. Mallards spent more time in water than Muscovy Ducks (41.0% vs. 9.1%), less time in grass (2.8% vs. 21.5%), and less time in urban areas (0.5% vs. 8.0%). Times spent by Mallards and Muscovy Ducks in …


Sirex Nigricornis (Hymenoptera: Siricidae) Larval Development Correlated With Tree Characteristics And Ophiostomoid Fungal Infection, Jess Hartshorn, Larry D. Galligan, Fred Stephen Feb 2021

Sirex Nigricornis (Hymenoptera: Siricidae) Larval Development Correlated With Tree Characteristics And Ophiostomoid Fungal Infection, Jess Hartshorn, Larry D. Galligan, Fred Stephen

The Great Lakes Entomologist

The native North American wood wasp, Sirex nigricornis F., has received significant attention over the last several years due to the introduction and successful establishment of the European wood wasp, S. noctilio L. in eastern North America. Larval size and development of S. nigricornis are important variables that can help to compare demography of the two species and predict future interactions. We measured head capsule width, body length, and weight of S. nigricornis larvae removed from 14 pine trees, felled across the Ozark and Ouachita National Forests of Arkansas in 2012. We also recorded the height at which larvae were …

The Probability Of Spotted Lanternfly, Lycorma Delicatula (Hemiptera: Fulgoridae), Escape Differs Among Life Stages And Between Two Trapping Techniques Commonly Used By Landowners, Sticky Bands And Duct Tape., Matthew Desko, Carolyne Schiebel, Samantha Silverman, Jessica Bickel, Karen Felton, Jennifer L. Chandler

The Great Lakes Entomologist

The invasive Lycorma delicatula (White) was first identified in Pennsylvania, U.S.A. in 2014, and has since increased its range to several Eastern states. Lycorma delicatula pose a serious threat to many native species, including hardwoods and grapes, and land owners are continually seeking effective traps to control populations. Both commercially-produced Web-Cote brand sticky bands and less expensive duct tape are often used by land owners to trap L. delicatula. However, the probability of escape from these adhesives has not been formally assessed, and almost certainly differs as a function of life stage and type of adhesive used. The purpose …

Oldest Indo-Pacific Lionfish (Pterois Volitans/P. Miles) Recorded From The Northwestern Gulf Of Mexico, Raven D. Blakeway, Alexander Q. Fogg, Glenn A. Jones

Gulf and Caribbean Research

Indo-Pacific lionfish (Pterois volitans/miles) were first detected off the coast of Florida in the 1980s, with aquaria release being the most likely mechanism for introduction. Since then, lionfish have proliferated through the Western Atlantic Ocean, Caribbean Sea, and Gulf of Mexico (GOM). Here, we report the oldest lionfish aged on record in the Western Atlantic, removed from Flower Garden Banks National Marine Sanctuary (FGBNMS) in the GOM. In August 2018, a research expedition removed 745 lionfish from FGBNMS, of which a subset were retained for age and growth estimation. The oldest lionfish was a 10 y old male, …


Raven Control From A Conservation Biology Perspective, David J. Delehanty Jan 2021

Raven Control From A Conservation Biology Perspective, David J. Delehanty

Human–Wildlife Interactions

The common raven (Corvus corax; raven) is a large, highly intelligent passerine songbird with a Holarctic distribution attributable to a high degree of plasticity in its foraging and nesting behavior. Historically, ravens have received special attention in human culture, being either respected or vilified. In the western United States, ravens are exploiting the expanding human enterprise, which provides them with unintended subsidies of food, water, and breeding locations, allowing ravens to expand their range and increase in population density and resulting in raven depredation threatening species of conservation concern. From a conservation biology perspective, increased raven populations present …

Turkish Journal of Zoology

The Harlequin Ladybird, Harmonia axyridis (Pallas, 1773), is native to Eastern Asia but it has been introduced to many countries in Africa, America, and Eurasia. In Turkey, H. axyridis is one of the most fast-spreading invasive alien species. Since the collection of the first specimens in 2010, H. axyridis spread almost all over the country. The species spreads fast in Turkey according to the new records, obtained originally from the field studies and the citizen science data. It was recorded for the first time from 19 of 81 Turkish provinces (Ankara, Antalya, Balıkesir, Bolu, Bursa, İstanbul, İzmir, Karaman, Kastamonu, Kırklareli, …

Turkish Journal of Zoology

The Asian chestnut gall wasp (ACGW), Dryocosmus kuriphilus, native to China was accidentally introduced into many countries worldwide, including Italy. Different susceptibilities have been reported in literature among cultivated plants belonging to different gene pools worldwide, but this aspect has not been sufficiently explored among wild chestnut populations. The aims of this multiyear study were (i) to assess differences in susceptibility to ACGW in wild C. sativa plants coming from different parts of Europe grown in an experimental plot in Central Italy, (ii) to preliminarily analyse the relationships between temperature, relative humidity and rain variables of winter and summer and …
