Game Theory And Artificial Intelligence In Just Preservation, David L. Dowe, Nader Chmait

Animal Sentience

We humans can show presumption, arrogance and many dubious traits. By virtue of being land-dwelling, dexterous, relatively intelligent, and having good communication hardware and (good) fortune, we have for recent millennia largely had dominion of our planet. Yet humans often do not treat themselves (let alone other species) particularly well. Treves et al.’s idea of a multispecies justice system — not “prioritizing humans” but “finding practical ways to work within human systems” — invites consideration.

Just Preservation, Trusteeship And Multispecies Justice, Francisco J. Santiago-Ávila, Adrian Treves, William Lynn

Animal Sentience

We are grateful to all the commentators who engaged with our target article. Some commentators have offered important insights into our proposed design and methods for legally intervening on behalf of futurity. Others have focused on theoretical considerations central to our proposal for multispecies justice and trusteeship. All have inspired modifications and further elaboration of our initial proposal. In this Response, we engage with the commentaries, integrating their suggestions, striving for convergence and complementarity, but also discussing points of divergence with our proposed framework where necessary. There is substantial overlap in the points of view of the three co-authors, but …

Efficient Coi Barcoding Using High Throughput Single-End 400 Bp Sequencing, Chentao Yang, Yuxuan Zheng, Shangjin Tan, Guanliang Meng, Wei Rao, Caiqing Yang, David G. Bourne, Paul A. O'Brien, Junqiang Xu, Sha Liao, Ao Chen, Xiaowei Chen, Xinrui Jia, Ai-Bing Zhang, Shanlin Liu

Background

Over the last decade, the rapid development of high-throughput sequencing platforms has accelerated species description and assisted morphological classification through DNA barcoding. However, the current highthroughput DNA barcoding methods cannot obtain full-length barcode sequences due to read length limitations (for example, a maximum read length of 300 bp for the Illumina’s MiSeq system), or are hindered by a relatively high cost or low sequencing output (e.g. a maximum number of eight million reads per cell for the PacBio’s SEQUEL II system).

Results

Pooled cytochrome c oxidase subunit I (COI) barcodes from individual specimens were sequenced on the …

Natural history collections are leading successful large-scale projects of specimen digitization (images, metadata, DNA barcodes), thereby transforming taxonomy into a big data science. Yet, little effort has been directed towards safeguarding and subsequently mobilizing the considerable amount of original data generated during the process of naming 15,000–20,000 species every year. From the perspective of alpha-taxonomists, we provide a review of the properties and diversity of taxonomic data, assess their volume and use, and establish criteria for optimizing data repositories. We surveyed 4,113 alpha-taxonomic studies in representative journals for 2002, 2010, and 2018, and found an increasing yet comparatively limited use …

Energy Development And Production In The Great Plains: Implications And Mitigation Opportunities, Jacqueline P. Ott, Bruce B. Hanberry, Mona Khalil, Mark W. Paschke, Max Post Van Der Burg, A.J. Prenni

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Energy is an integral part of society. The major US energy sources of fossil fuels (coal, oil, natural gas); biofuels (ethanol); and wind are concentrated in grassland ecosystems of the Great Plains. As energy de- mand continues to increase, mounting pressures will be placed on North American grassland systems. In this review, we present the ecological effects of energy development and production on grassland sys- tems. We then identify opportunities to mitigate these effects during the planning, construction, and pro- duction phases by using informed methodology and improved technology. Primary effects during energy development include small- and large-scale soil disturbance …

Temporospatial Shifts In Sandhill Crane Staging In The Central Platte River Valley In Response To Climatic Variation And Habitat Change, Andrew J. Caven, Emma M. Brinley Buckley, Kelsey C. King, Joshua Wiese, David M. Baasch, Greg D. Wright, Mary Harner, Aaron T. Pearse, Matt Raabe, Dana Varner, Brice Krohn, Nicole Arcilla, Kirk D. Schroeder, Kenneth F. Dinan

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Over 80% of the Mid-Continent Sandhill Crane (Antigone canadensis) Population (MCP), estimated at over 660,000 individuals, stops in the Central Platte River Valley (CPRV) during spring migration from mid-February through mid-April. Research suggests that the MCP may be shifting its distribution spatially and temporally within the CPRV. From 2002 to 2017, we conducted weekly aerial surveys of Sandhill Cranes staging in the CPRV to examine temporal and spatial trends in their abundance and distribution. Then, we used winter temperature and drought severity measures from key wintering and early migratory stopover locations to assess the impacts of weather patterns …

Host Relationships And Geographic Distribution Of Species Of Blanchard, 1848 (Onchoproteocephalidea, Onchobothriidae) In Elasmobranchs: A Metadata Analysis, Francisco Zaragoza-Tapia, Griselda Pulido-Flores, Scott L. Gardner, Scott Monks

Scott L. Gardner Publications

Species of Acanthobothrium have been documented as parasites of the spiral intestine of elasmobranchs. Results of a metadata analysis indicate that 114 species of elasmobranchs have been reported as hosts of 200 species of Acanthobothrium. The metadata analysis revealed that 3.7% of species of sharks and 14.9% of species of rays that have been reported as hosts to date; some species are parasitized by more than one species of Acanthobothrium. This work provides a Category designation, as proposed by Ghoshroy and Caira (2001), for each species of Acanthobothrium. These Category designations are a tool to facilitate comparisons …

Obituary: Sydney Anderson (1927–2018), Scott Lyell Gardner, Robert M. Timm, Nancy Olds, Hugh H. Genoways

Scott L. Gardner Publications

On August 12, 2018, the American Society of Mammalogists (ASM) lost one of its giants of the latter half of the 20th century when Sydney Anderson quietly passed away at his home in Birmingham, Alabama, at the age of 91. “Syd,” to his many friends and colleagues, was born on January 11, 1927 in Topeka, Kansas, to Robert Grant and Evelyn Fern (Hunt) Anderson.

Anderson began his professional career at the University of Kansas, where for four years (1955–1959) he served as Assistant Curator in charge of mammals in the Museum of Natural History, and Instructor in the Department of …

More Than Meets The Eye: A Taxonomic Revision Of The Nearctic Species In The Eye-Gnat Genus Amiota Loew (Diptera: Drosophilidae), Lance E. Jones

Dissertations and Theses

Thorough biotic inventories are still needed even in families as seemingly well-studied as fruit flies (Diptera: Drosophilidae). Drosophilidae have had an outsize effect on the history of biology because of their pivotal role in the study of genetics, development, and evolution. Even with more than a century of intensive study, large gaps remain in our understanding of diversity in this fly family, including well-studied areas such as North America. This thesis presents a taxonomic revision of the Nearctic species of the genus Amiota Loew. Twenty-three species are identified as being new to science for publication at a later date. This …

Small Mammal Communities In Grasslands At The Grand Forks Air Force Base, North Dakota, Usa, Lynda R. Lafond, Elizabeth H. Rave, Kathryn A. Yurkonis

The Prairie Naturalist

Small mammals are important in grasslands but are often overlooked in management and reconstruction efforts. We sampled small mammals in three sites on the Grand Forks Air Force Base (GFAFB) located in central Grand Forks County, North Dakota, USA. The study sites varied in their management history and represented the three major types of grasslands (reconstructed prairie, old field, and hay field) within Grand Forks County. We captured 463 individuals of six species with Sherman live traps in summer (June, July, August) 2014 and 2015. We captured the most individuals and species (295 individuals of 5 species), including all shrews …

Wood Frogs (Rana Sylvatica) In Southwestern Roberts County And Western Grant County, South Dakota, Dennis R. Skadsen, Drew R. Davis

The Prairie Naturalist

Historically, only six records of Wood Frogs (Rana sylvatica) existed from South Dakota, all represented by museum specimens. A single specimen was collected from Hartford Beach on Big Stone Lake, Roberts County in 1922 (National Museum of Natural History, Smithsonian Institution [USNM] 65452) and five Wood Frogs were collected near the outlet of Blue Dog Lake, Day County in 1929 (USNM 312618– 312622; Fig. 1). After the 1920s, no other Wood Frogs were reported in South Dakota for the next six decades, and the species was presumed extirpated. Over (1923, 1943) reported the species was common in the …

Trends In A Greater Prairie Chicken Population Established By Translocation In North Dakota, Gary Huschle, John E. Toepfer

The Prairie Naturalist

In 1992, an effort was undertaken by the North Dakota Game and Fish Department (NDGFD), U.S. Fish and Wildlife Service, and North Dakota Chapter of the Wildlife Society to reestablish a viable population of greater prairie chickens (Tympanuchus cupido pinnatus; hereafter prairie chickens) in northeast North Dakota. The release area was centered on the Prairie Chicken Wildlife Management Area located 22.5 km northwest of Grand Forks, North Dakota, in the northern part of Grand Forks County. Topography consists of poorly drained, saline flats and swells separated by poorly drained swales and sloughs in the Red River Valley (Beringer 1995). Permanent …

Patterns And Potential Causes Of Changing Winter Bird Distributions In South Dakota, David L. Swanson, Reza Goljani Amirkhiz, Mark D. Dixon

The Prairie Naturalist

Average winter temperatures in the north-central United States have been increasing since the 1970s, and this warming might influence winter distributions of birds in the region. Species potentially influenced by such winter warming include short-distance migrants for which the northern boundary of the winter range is influenced by temperature, such as hermit thrush (Catharus guttatus), yellow-rumped warbler (Setophaga coronata), and fox sparrow (Passerella iliaca). We examined winter records during 1974–2017 from a citizen-science bird observation database for South Dakota to determine recent trends in winter records for these three species. We compared their occurrence patterns with those for three benchmark …

Short-Term Estimate Of Finfish Bycatch Discards In The Inshore Artisanal Shrimp Fishery Of Guyana, Leanna Kalicharan, Hazel A. Oxenford

Gulf and Caribbean Research

The artisanal shrimp fishery in Guyana is important for livelihood and food security, involving around 300 vessels owned and crewed exclusively by Guyanese nationals. This fishery uses Chinese seines and operates in major river estuaries. It targets penaeid shrimp, but also retains some finfish and is known to discard a significant but undocumented quantity of smaller finfish bycatch. The lack of knowledge regarding the bycatch is a concern for fishery management and biodiversity conservation. In this study, we quantify for the first time the finfish bycatch discards through onboard observations (July—August 2016) of a single typical vessel operating in the …

The Effects Of Woody Vegetation Encroachment And Removal Within A Coastal Fen, Joseph Saler

Cal Poly Humboldt theses and projects

Early successional wetland habitat is being lost in temperate regions worldwide as a result of changes in disturbance regimes that allow for the establishment and dominance of woody species. In particular, this phenomenon is pronounced in fens, which harbor high numbers of rare herbaceous species that require early successional habitat. I investigated the relationship between woody vegetation encroachment and herbaceous species diversity within a Northern California coastal fen that has been undergoing encroachment by woody vegetation for ca. 80 years by recording species richness and cover data from 338 permanent plots throughout the fen. I also investigated the effect of …

The Importance Of Surface Mining As A Landscape Variable In Shaping Wild Bee Communities In Central Appalachian Forests, Amanda Sheryl Dunaway

Online Theses and Dissertations

Anthropogenic disturbance has led to widespread losses in biodiversity. Native bees (Hymenoptera, Apoidea) provide essential pollination services and have been declining in abundance dramatically in recent years. One potential cause of these declines is anthropogenic disturbance. Eleven sites were established in Southeastern Kentucky, U.S.A. where surface mining for coal is common. Data was analyzed using generalized linear mixed-effect models to detect the most important landscape scale variables, including mining, in shaping bee communities. Bee species richness was significantly lower on sites that contained surface mines, but abundance was similar between mined and unmined sites. The proportion of each nesting group …

Measuring Variation In Body Morphology And Life History Traits In Brook Stickleback (Culaea Inconstans), Eastern Washington, Usa, Lily Crytser

EWU Masters Thesis Collection

For freshwater ecosystems, invasive species are considered a major threat to biodiversity, and pose a challenge to those attempting to advance management strategies aimed at conserving natural populations. An invasive species’ ability to successfully invade a new ecosystem may be influenced by phenotypic plasticity, flexibility of life history traits, and the ability to migrate/disperse, among other factors. Brook stickleback (Culaea inconstans) have been a concern in eastern Washington since 1999 when they were discovered in water bodies on Turnbull National Wildlife Refuge. The purpose of this project was to describe potential variation in body morphology traits between systems that differed …

The Vezo Communities And Fisheries Of The Coral Reef Ecosystem In The Bay Of Ranobe, Madagascar, Shane Abeare

LSU New Orleans Theses and Dissertations

Madagascar, a country whose extraordinary levels of endemism and biodiversity are celebrated globally by scientists and laymen alike, yet historically has received surprisingly little research attention, is the setting of the present dissertation. Here, I contribute to the need for applied research by: 1) focusing on the most intensely fished section of the Toliara Barrier Reef, the Bay of Ranobe; 2) characterizing the marine environment, the human population, and the fisheries; and 3) collecting the longest known time-series of data on fisheries of Madagascar, thereby providing a useful baseline for future analyses. In Chapter 1, the bathymetry of the Bay …
