Alabama Agricultural Producers’ Experiences With Wild Pigs (Sus Scrofa) And Their Preferences Concerning Wild Pig Management, Hailey E. Ellis, Luren M. Jaebker, Alan D. Bright, Mark D. Smith, Keith M. Carlisle

United States Department of Agriculture Wildlife Services: Staff Publications

Government agencies and landowners use a variety of lethal methods to reduce invasive wild pig populations and resulting agricultural damages. To provide decision-makers with information regarding Alabama farmers’ experiences with wild pigs and their preferences for management actions, we surveyed Alabama Farmers Federation members in 2020. We found that wild pigs were commonly present on livestock, timber, and crop production acreage, but wild pig damages and costs were much more common among crop producers. Respondents' wildlife acceptance capacity for wild pigs was low and all lethal control methods were considered aceptable by most reposndents, particularly those performed by landowners. While …

Transitions Into Freezing Environments Linked With Shifts In Phylogenetic Integration Between Vitaceae Leaf Traits, Charles Tomo Parins-Fukuchi, Gregory W. Stull, Jun Wen, Jeremy M. Beaulieu

Biological Sciences Faculty Publications and Presentations

Understanding how the intrinsic ability of populations and species to meet shifting selective demands shapes evolutionary patterns over both short and long timescales is a major question in biology. One major axis of evolutionary flexibility can be measured by phenotypic integration and modularity. The strength, scale, and structure of integration may constrain or catalyze evolution in the face of new selective pressures. We analyze a dataset of seven leaf measurements across Vitaceae to examine how correlations in trait divergence are linked to transitions between freezing and nonfreezing habitats. We assess this by applying a custom algorithm to compare the timing …

To Be Conscious Or Not To Be, Bjørn Grinde

Animal Sentience

Carolyn Ristau has done a fine job summarizing the work and life of the zoologist Donald Griffin. Most scientists now accept the existence of animal sentience, but identifying which species possess consciousness remains controversial. Griffin defined consciousness as "the subjective state of feeling or thinking about objects and events.” Nonconscious processes are faster and more energy-efficient, however, and often drive behavior. Consciousness probably evolved for complex decision-making, shaped by evolutionary continuity, with feelings as a common currency for evaluating outcomes. Its survival advantage may be limited, and its presence across species varies depending on evolutionary trajectories.

Tityopsis Rolandoi Sp. N. (Scorpiones: Buthidae) From Cuba, František Kovařík, Mark Stockmann, František Šťáhlavský, Sheyla Yong

Euscorpius

A new species Tityopsis rolandoi sp. n. is described from Cuba, fully illustrated with color photos showing its morphology and habitus. T. rolandoi sp. n. is the only species of the genus with a combination of two characters: movable finger shorter than carapace and chela length/width ratio 3.6 in male. This species also has a characteristic shape of a median smooth patch of sternite V, which is almost oval in male. In addition to morphology, we present the information about the karyotype of T. rolandoi sp. n. (2n=20) and T. sheylae (2n=22).

Communication In Noise Is The Window On Cognition, R. Haven Wiley

Animal Sentience

As Griffin surmised, communication is the window on cognition, but as shown here, only if it is noisy. This commentary is an invitation to consider the full implications of the evolution of noisy communication. A combination of Information Theory, Signal Detection Theory, and Natural Selection, in a unified theory of the evolution of communication, reveals that noise is inevitable. All organisms are thus decision makers. Perception, thought, freedom of decision, self-awareness, metabolism, and natural selection all share the consequences of signals in noise. A full understanding of each requires attention to the errors of receivers. Griffin’s hunch is correct with …

Habitat Preferences Of The Hiwassee Crayfish (Cambarus Hiwasseensis) And Appalachian Brook Crayfish (Cambarus Bartonii Cavatus) In A Headwater Stream, Johnathan G. Davis

Georgia Journal of Science

The Hiwassee crayfish Cambarus hiwasseensis (CH) is an endemic species to the Hiwassee River watershed in north Georgia and western North Carolina that is sympatric with the more widespread Appalachian Brook crayfish Cambarus bartonii cavatus (CB). This was the first study to investigate CH habitat use, comparing CH habitat to CB habitat in Corn Creek, a small, second-order stream in the Hiwassee River watershed. From August to November 2016 and January to April 2018, 15 habitat parameters were measured for 154 1-m² quadrants randomly sampled from an 800-m stream reach. Mann-Whitney U tests compared habitat parameters between present and …

The Costs Of Ecosystem Disturbances, E. Wesley F. Peterson

Cornhusker Economics

Presents an illustration of the interdependencies inherent in natural ecosystems. An ecosystem may be defined as: “… a single environment and every living (biotic) organism and non-living (abiotic) factor that is contained within it or characterizes it. An ecosystem embodies every aspect of a single habitat, including all interactions between its different elements” (Knapp 2020). In such interdependent systems, removal of one or more of the essential “elements” can severely disrupt the functioning of the system and such disruptions can give rise to negative impacts on the environment and human health and well-being.

Evaluating Growth Of Coastal Grass In Recycled Glass Sand: Evidence For Safe Application In Coastal Restoration, Allison B. Huddleston

Honors Capstones

Louisiana’s coastal land loss results from complex interactions of anthropogenic and naturally occurring processes that impact sediment supply in the Mississippi river delta. Given the coastline's vital role in the state’s economy, Louisiana has made significant investments in coastal restoration projects, including planting native vegetation and adding borrowed sediments. The amount of sediment needed to maintain Louisiana’s existing coastline exceeds the available amount that could be extracted, and state officials have since identified this lack of sustainable sediment resources as a critical limitation for future restoration projects. One proposed solution to address this shortage is using recycled crushed glass cullet …

Understanding The Welfare Of Aquarium Fish, Paul Rose

Animal Sentience

Bony fishes (Osteichthyes) are prevalent in public and domestic aquaria, yet evidence-based welfare practices exist for only a limited number of species. Oldfield & Bonano’s (O&B’s) target article highlights critical questions about the wellbeing and sociality of Osteichthyes. Advancing research on their biology, physiology, psychology, and behavior is essential to develop and validate welfare measures, ensuring guidelines for welfare-focused housing and husbandry.

Examining Wildfire Dynamics Using Ecostress Data With Machine Learning Approaches: The Case Of South-Eastern Australia's Black Summer, Yuanhui Zhu, Shakthi B. Murugesan, Ivone K. Masara, Soe W. Myint, Joshua B. Fisher

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Wildfires are increasing in risk and prevalence. The most destructive wildfires in decades in Australia occurred in 2019–2020. However, there is still a challenge in developing effective models to understand the likelihood of wildfire spread (susceptibility) and pre-fire vegetation conditions. The recent launch of NASA's ECOSTRESS presents an opportunity to monitor fire dynamics with a high resolution of 70 m by measuring ecosystem stress and drought conditions preceding wildfires. We incorporated ECOSTRESS data, vegetation indices, rainfall, and topographic data as independent variables and fire events as dependent variables into machine learning algorithms applied to the historic Australian wildfires of 2019–2020. …

New natural history elements and distribution records of several North American butterflies are reported. While diversity and distribution of butterflies in North America are commonly believed to be fully known, the findings presented here show that much is yet to be learned of our butterfly fauna.

Determining The Long-Term Effectiveness Of Seeding Post-Dam Removal In The Elwha River, Wa, Through Soil Seed Bank Analysis, Makenna Tabino, Rebecca Brown

2024 Symposium

Following the historic dam removal along the Elwha River in Olympic National Park, we are evaluating the impact of seeding in the former Lake Mills reservoir by examining the soil seed bank composition. The Elwha River had the largest dam removal project in history, and the second largest ecological restoration project in National Parks Service history. Active restoration (seeding and planting) took place in terraces and valley walls, the two dominant landform types found in the former reservoir. While the plant community in the former dam reservoirs is well documented, the soil seed bank remains unexplored.

My objective is to …

Repeated Shifts In Sociality Are Associated With Fine-Tuning Of Highly Conserved And Lineage-Specific Enhancers In A Socially Flexible Bee, Beryl M. Jones, Andrew E. Webb, Scott M. Geib, Sheina Sim, Rena M. Schweizer, Michael G. Branstetter, Jay D. Evans, Sarah D. Kocher

Entomology Faculty Publications

Comparative genomic studies of social insects suggest that changes in gene regulation are associated with evolutionary transitions in social behavior, but the activity of predicted regulatory regions has not been tested empirically. We used self-transcribing active regulatory region sequencing, a high-throughput enhancer discovery tool, to identify and measure the activity of enhancers in the socially variable sweat bee, Lasioglossum albipes. We identified over 36,000 enhancers in the L. albipes genome from 3 social and 3 solitary populations. Many enhancers were identified in only a subset of L. albipes populations, revealing rapid divergence in regulatory regions within this species. Population-specific enhancers …

Effects Of Forest Succession On Ram's Head Lady's Slipper (Cypripedium Arietinum) Populations In The Grand Sable Dunes, Mi, Katelyn J. Dewitt

All NMU Master's Theses

Ram’s head lady slipper (Cypripedium arietinum) is rare across its range, but the Grand Sable Dunes (GSD) on the southern shore of Lake Superior harbors the largest known population in North America. It thrives in jack pine (Pinus banksiana) islands throughout the dunes. In this study, I updated the population status of ram’s head lady’s slipper at GSD and tracked changes in its distribution and reproductive health after a 14- year period since Bozic (2015) first surveyed GSD. I counted orchids, flowers, and fruit set in 741 1-m radius plots using stratified random sampling across 44 islands. I also resurveyed …

What Drives Gut Microbial Diversity And Community Structure Among Closely-Related Host Species?, Rylee Jensen

All NMU Master's Theses

The gut microbiome (GMB) of mammals hosts an important community of microbes that perform countless micro-ecosystem services for the host and are influenced by numerous factors including host physiology, environment, and phylogeny. Phylogeny may have a unique effect on GMB diversity and community structure (i.e., a GMB profile) via phylosymbiosis, a theory in which the evolution of hosts matches the evolution of their associated microbiota. Elucidating phylosymbiosis in mammals is difficult because multiple intrinsic and extrinsic factors collectively drive individual GMB variation. Thus, there is a need to simultaneously analyze the role of physiology, environment, and phylogeny on shaping host …

Rabbit Control: Warren And Harbourage Destruction, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

If correctly and appropriately undertaken, the destruction of rabbit warrens, or modification of the habitat so it becomes less favourable to rabbits, can be an important and effective part of reducing the impacts of rabbits.

Destruction of warrens can improve the overall effectiveness of rabbit control programs, even though many rabbits live and shelter above-ground under bushes, and in scrub). If undertaken properly, the ripping of rabbit warrens can often provide a relatively permanent and long-term benefit. Similarly, removing or modifying other forms of rabbit-harbourage (for example, removing rock piles) can help, particularly in semi-urban areas or on smallholdings.

Rabbit Control In Urban And Semi-Urban Areas, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

This factsheet provides information on control options for rabbits in urban and semi-urban areas in Western Australia (WA).

Rabbits cause considerable losses to agricultural and horticultural industries. They can cause serious environmental problems, such as soil erosion and degradation of native vegetation. Rabbits also compete with native fauna for food and habitat.

Rabbits may be a problem or a nuisance in urban environments where they can damage lawns and gardens, buildings, garages, and sheds. Rabbits can also damage golf courses, sports grounds, and parkland reserves.

The options for control of rabbits in urban areas are more limited than in rural …

Rabbit Fencing To Protect Crops And Pastures, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

This factsheet outlines the use of fencing to protect crops and pasture from rabbits.

Rabbits cause an estimated loss of $217 million each year to Australian agricultural production and cause significant environmental damage. In Western Australia (WA), areas of native vegetation, particularly on sandy ridges that would otherwise be subject to wind erosion, have been retained on farms. Bush remnants are a major refuge habitat for rabbits, which can cause considerable damage to nearby pastures and crops. A measure of rabbit control can be achieved by poisoning around bush remnants in late summer or autumn, prior to seeding. To be …
