Policy Design For Biodiversity: How Problem Conception Drift Undermines "Fit-For-Purpose" Peatland Conservation, Benjamin Cashore, Ishani Mukherjee, Altaf Virani, Lahiru S. Wijedasa

Research Collection School of Social Sciences

For over two decades, scientists have documented the alarming decline of global Peatland ecosystems, regarded as the planet’s most crucial carbon sinks. The deterioration of these unique wetlands alongside their policy attention presents a puzzle for policy scientists and for students of anticipatory policy design. Two contrasting explanations have emerged. Some argue that pressures from economic globalization compel governments to relax environmental standards, while others point to deficiencies in policy design and implementation. Our paper applies Cashore’s Four Problem Types framework to assess a more nuanced explanation: that failure of global and local policies to curb ecosystem degradation is owing …

Morphometric Analysis And Taxonomic Re-Evaluation Of Pepsis Cerberus Lucas And P. Elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini), Frank E. Kurczewski, Akira Shimizu, Diane H. Kiernan

Insecta Mundi

Hurd (1952) separated Pepsis cerberus Lucas from P. elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini) based on external morphology and biogeography. Vardy (2005) synonymized the familiar and historically well-documented P. cerberus and P. elegans, combining these Nearctic taxa with several Neotropical variants in an extremely broad definition of P. menechma Lepeletier. In doing so, Vardy (2005) breached the principle of nomenclatural stability. He ignored the prevailing usage and clearly violated articles 23.2, 23.3 and 23.9.1.2 of the ICZN (1999). Morphological differences, ecological divergence, and narrow sympatric geographic distribution of P. cerberus and P. elegans …

A New Species Of Paranthrene Hübner (Lepidoptera: Sesiidae) From The Northern Midwest United States, William H. Smith Iii, William H. Taft Jr., Anthony I. Cognato

Insecta Mundi

A clearwing moth species, Paranthrene sogaardi Taft and Smith, 2024, new species, is described from Michigan and Minnesota. The recognition of this new species is based on a phylogeny estimated from mitochondrial cytochrome oxidase I and wingless DNA sequences of 25 specimens representing all Paranthrene Hübner species including individuals from various locations. Paranthrene sogaardi new species was monophyletic and differed from Paranthrene tabaniformis Rottenburg, 1775 by a mean of 7.6% COI pairwise “p” distance, coloration, and genitalic morphology.

Taxonomic Notes On Velvet Ants Of The Genus Timulla Ashmead, 1899 (Hymenoptera: Mutillidae) In The United States Of America And Canada, George C. Waldren

Insecta Mundi

The exclusively New World velvet ant genus Timulla Ashmead, 1899 (Hymenoptera: Mutillidae: Mutillinae: Trogaspidiini) contains 180 species and ten subspecies. Most of these species are known from a single sex, and the validity of the subspecies has not been evaluated since their original description in 1937 and 1938. The Timulla fauna of the United States of America includes thirty species and eight subspecies, and the fauna of Canada includes three species. The faunas of these two countries were critically studied with the following results. Out of the eight total subspecies, seven were found to be structurally identical to and sympatric …

Internet-Based Data Platforms Re-Define The Distributions Of Some Large Crabronid Wasps In Arkansas (Hymenoptera: Crabronidae), David E. Bowles

Insecta Mundi

The geographic distributions of three large wasps, Sphecius speciosus (Drury), Stictia carolina Fabricius, and Stizus brevipennis Walsh (Hymenoptera: Crabronidae), occurring in Arkansas are defined using museum specimens and three internet-based data platforms. The internet-based data platforms generally provided more county location records than museum records. Using data from internet sources for easily identified species can better serve to illustrate the known distributions for some species thus making for a powerful tool elucidating distributional patterns and conservation planning.

Reassignment Of Some Caryospora Species (Apicomplexa: Eimeriidae) To Eumonospora (Apicomplexa: Sarcocystidae) And A Summary, Donald W. Duszynski

MANTER: Journal of Parasite Biodiversity

This review was crafted to clear up some of the current confusion regarding the correct taxonomic placement of those apicomplexan coccidians that produce unique monosporocystic octosporozoic (1 sporocyst with 8 sporozoites) oocysts during the sexual phase of their life history in vertebrate hosts. Currently, such oocysts have been placed in 1 of 4 genera, Avispora, Caryospora, Karyospora, or Eumonospora, 2 of which are no longer accepted or useful (Avispora and Karyospora). My review suggests that to present (2023) there are 62 valid Caryospora and 26 valid Eumonospora species. Caryospora species are recorded from a bird …

Biodiversity Loss & Urban Heat: A Nature- Based Wildlife Policy For The Las Vegas Metro, Zachary Billot

Student Research

As the population of the Las Vegas Metro continues to grow, new developments expand on the periphery. As Las Vegas continues to increase in size and develop further into wildlife habitat, not only are native animals and plants endangered, but residents are at risk of increasingly dangerous urban heat given the increase in impervious cover that makes Las Vegas the 2nd fastest warming metro in the U.S. This policy brief examines current policy and practice in place to highlight the need for positive human-wildlife interaction that will address the growing threat of biodiversity loss and heat vulnerability. This policy brief …

Land Use Intensification And Bio-Resource Utilisation In The South Pacific Islands, David Lopez Cornelio

International Journal of Islands Research

The long and gradual colonisation of the Pacific islands created settlements of cohesive social networks that fused or were displaced by western ways of life, trade and governance through the centuries. In this paper, a historical review of the processes of island discovery, plants domestication, and of land use practices are discussed alongside the main socioeconomic drivers of land cover change. The native trees of the South Pacific constitute an invaluable resource for sustainable development; they were used and domesticated for thousands of years but logging, commercial agriculture, mining, the introduction of exotic species and urban expansion are threatening them …

With Love, ; An Interdisciplinary And Intersectional Look At Why Creativity Is Essential, Theo Starr Gardner

Whittier Scholars Program

My Whittier Scholars Program self-designed major, Teaching Creativity, is a mixture of Art, Literature, and Education classes. My research and praxis classes have been focused on the ‘how?’s and 'why?’s of creativity, so it felt only right that my project should be a constructivist, generative project. The project I have been working on throughout my time at Whittier, and that has just fully come to fruition on April 11th, 2024, was a solo art gallery/open mic event entitled ‘With Love,’. With Love, was conceptually inspired by the research I’ve conducted on creativity and creative arts education over the past few …

Greening The Edge: Investigating Riparian Buffer Restorations In A Pastoral Setting And Their Effects On Soil Carbon And Microbial Community Composition., Seth Mccullough

Masters Theses, 2020-current

Riparian buffer restoration represents a critical strategy for enhancing ecosystem health and resilience in agricultural landscapes. This study investigates the effects of riparian buffer restoration on soil properties, microbial communities, and carbon dynamics in Rockingham County, VA. Through a comprehensive field study, we assessed the physicochemical properties of soil, microbial biomass, community composition, and soil carbon storage in restored and unrestored riparian buffers. Our findings reveal significant improvements in soil physical properties in restored buffers, including increased soil moisture (p < 0.05) and decreased bulk density (p < 0.01), indicating enhanced soil structure and water retention capacity. While no significant differences were detected in soil pH or cation exchange capacity, restored buffers exhibited higher soil carbon stocks (p < 0.05) and carbon-to-nitrogen ratios, suggesting potential differences in nutrient cycling processes and organic matter decomposition rates. Moreover, restored buffers showed increased microbial biomass (p < 0.01), potentially driven by improved habitat conditions and shifts towards a fungal-dominated microbial community.

Although no significant differences were found in overall microbial community composition between restored and unrestored sites, specific shifts in bacterial …

Climate Change And Environmental Crises In Coastal Cities: Charleston Vs New York City, Nolan Rodriguez

Student Theses 2015-Present

This paper addresses the increasing vulnerability that coastal communities face regarding climate crises and rising sea levels. Specifically, this paper investigates the environmental crises facing Charleston, South Carolina, and New York City. The geographical location of these cities places a more severe threat upon their environment, as opposed to urban collectives removed from the immediate effect of rising sea levels. A cross-examination of politics and economics is discussed in order to determine the causal relationship of each city’s engagement with its surrounding environment. This paper examines how each city is affected by climate change, what measures are in place to …

Fecal Genomics Provides Insights On Connectivity Of Endangered Wildlife In A Human Dominated Landscape, Abhinav Tyagi

Theses and Dissertations

Many mammalian species, facing severe historic range reductions, now inhabit fragmented habitats. Habitat fragmentation involves the reduction of habitat into smaller patches, increasing distances between them, and eventually leading to small isolated populations. Species' responses to habitat alteration may vary based on factors such as body size, dispersal ability, and abundance. Understanding these differences is crucial for effective multispecies conservation planning. Genomic data, within a landscape genetic framework, are increasingly applied to evaluate the effects of habitat fragmentation and understand influential landscape features for connectivity. The quantity of data enhances the power and precision of assessing landscape impacts on gene …

Three Additions To The False Click Beetle (Coleoptera: Elateroidea: Eucnemidae) Fauna In The Nearctic Region, Robert L. Otto

Insecta Mundi

Three species of false click beetles (Coleoptera: Eucnemidae) are added to the Nearctic fauna. One new species, Isorhipis bicolor, is described from a small series collected in Florida, U.S.A. Eighteen specimens collected from Georgia were identified as Dyscharachthis amplicollis (Fleutiaux), new U.S.A. records for a species previously taken from Japan and Southeast Asia. Examination of a series of eucnemids collected by Kyle Schnepp in Florida allowed me to revisit the Deltometopus fauna in eastern North America. Antennal structures present in a series of male specimens in the loan and past examined specimens are definitive enough to resurrect Deltometopus …
