Biojardineras In Monteverde: A Mixed Method Approach To Examine Greywater Treatment, Elyssa Allen, Jackson Anderson, Brayden Dostal, Alan Hernandez, Kacy Moe, Facundo Pereya-Kluser

Monteverde Institute: Tropical Ecology and Conservation

Rural and semi-rural regions around the globe often struggle with inadequate wastewater treatment infrastructure, thereby negatively impacting the public and environmental health of the region. Due to its rural nature and current infrastructure, the Monteverde Zone (MVZ) in Costa Rica lacks a centralized wastewater system, with many homes relying on septic tanks for wastewater treatment. To prevent overloaded flows to septic tanks, greywater from kitchens, laundry, showers, and sinks is often discharged separately to the environment with no treatment. This pollutes the surrounding water bodies and streets with pathogens, soap, excess nutrients, as well as fats, oils, and grease (FOG). …

Where Are The Criminologists?: The Persistent Absence Of The Field In Genocide Research, Grace Allbaugh, Susan A. Woollen, Jacqueline L. Schneider, Joanne Savage

Genocide Studies and Prevention: An International Journal

The rallying cry of “Never Again” was heard worldwide after the Nazis’ annihilation of Jews and other victims were discovered after WWII. The global community promised that the crime of genocide would be prevented and signatory parties of the United Nations Convention on the Prevention and Punishment of Genocide (December 9, 1948) would do everything in their power to prevent another Holocaust from occurring. Unfortunately the “crime of all crimes” remains an almost permanent fixture in international news while signatory parties remain reluctant to call the ongoing conditions genocide. The field of genocide studies is built upon an interdisciplinary field …

Teaching Ai Ethics And Skepticism: The Impact Of Instruction On Ethical Usage On Students’ Perceptions, Jenna D. Justin Jul 2025

Teaching Ai Ethics And Skepticism: The Impact Of Instruction On Ethical Usage On Students’ Perceptions, Jenna D. Justin

Journal of Practitioner Research

This study investigates the ethical implications of artificial intelligence (AI) in K-12 education, focusing on how explicit instruction influences students' perceptions of AI tools like ChatGPT. Conducted with 80 sixth-grade students at A.D. Henderson University School and FAU High School, the research tracks changes in student understanding and skepticism of AI following a World History unit. Pre- and post-instruction surveys revealed a decline in comfort with AI as students became more aware of its ethical concerns, including plagiarism, bias, and misinformation. The findings suggest integrating AI ethics into the middle school curriculum to foster responsible AI usage among students.

Marine Ornithology

In 2022, highly pathogenic avian influenza (HPAI) virus resulted in mass mortality throughout seabird colonies in the North Atlantic Ocean. While mortalities and transmission of the virus are being documented, other effects are less understood. We documented nest abandonment and unprecedented reproductive failure by Northern Gannets Morus bassanus at Cape St. Mary’s, Newfoundland and Labrador, Canada, the species’ southernmost colony. Reproductive success in 2022 was the lowest on record at 17%, which was likely a result of adults abandoning the nest and succumbing to avian influenza virus (AIV) infection. Following the AIV outbreak at Cape St. Mary’s, we also documented …

Tracked Gulls Help Identify Potential Zones Of Interaction Between Whales And Shipping Traffic, Megan A. Cimino, Heather Welch, Jarrod A. Santora, David Kroodsma, Elliott L. Hazen, Steven J. Bograd, Pete Warzybok, Jaime Jahncke, Scott A. Shaffer

Marine Ornithology

Seabird-vessel interactions are often studied through the lens of fisheries bycatch, but seabirds encounter many watercraft types. Western Gulls Larus occidentalis breeding on the Farallon Islands (California, USA) have a foraging domain that encompasses both shipping lanes and productive fishing grounds, resulting in ample opportunities for vessel encounters. Previous research showed that these Western Gulls can serve as ecosystem indicators because their foraging behavior is linked to ocean prey conditions, and because their foraging grounds overlap with that of Humpback Whales Megaptera novaeangliae, which can make prey accessible. Because ship strikes and entanglement in fishing gear are concerns for whales …

Effects Of A Vagrant Arctic Fox Alopex Lagopus On An Isolated Newfoundland Seabird Community, Raul Zabala Belenguer, Amy C. Wilson, Katja H. Kochvar, Sabina I. Wilhelm, Pierre-Paul Bitton

Marine Ornithology

We report predation by an Arctic Fox Alopex lagopus on two seabird species, Atlantic Puffins Fratercula arctica and Leach’s Storm Petrels Hydrobates leucorhous, nesting on Bakeapple Island, Little Fogo Islands, Newfoundland, Canada. This event took place in 2022, when a whole-island inspection revealed that fox, facilitated by over-ice invasion, killed at least 139 adult storm petrels and 8 puffin chicks. The fox also dug out 83 storm petrel and 4 puffin burrows. Breeding by seabirds on the island, which harbours some of the northernmost colonies in Newfoundland, was also largely disrupted; we documented extremely low egg and chick production values …

Intra-Annual Shifts In Atlantic Puffin Fratercula Arctica Depredation And Kleptoparasitism By Larus Gulls At A Multi-Species Seabird Colony, Gibson M. Rieger, Gail K. Davoren

Marine Ornithology

Great Black-backed Gulls Larus marinus and American Herring Gulls L. argentatus smithsonianus are considered dietary generalists at the population level: they consume a variety of prey types, including the adults and offspring of other seabirds, and they shift among prey types as availability varies. Atlantic Puffin Fratercula arctica adults, eggs, and chicks are often the target of depredation, and adults are also susceptible to kleptoparasitic attacks by large gulls during their summer breeding season in coastal Newfoundland, Canada. We investigated the depredation and kleptoparasitism of puffins by large gulls during July–August 2021/22 at a multi-species breeding colony on the northeast …
