The Arctic Ocean Region : Biodiversity, Governance And Protective Measures, Antonios Andreadakis, Graeme Chesters, Dimitrios Dalaklis, 90 North Foundation

Reports

EXECUTIVE SUMMARY

• The Arctic Ocean region stands at the forefront of global environmental transformation, serving as a harbinger of climate change and a frontier for emergent geopolitical and economic interests.

• The Arctic region's economic potential, particularly in shipping and resource extraction, appears to offer shorter trade routes, reduced fuel consumption, and increased access to high-value resources. However, this analysis largely ignores the complex geo-physical, environmental and geographical limitations of the region.

• The fragility of Arctic Ocean ecosystems – characterized by slow ecological recovery, specialised biodiversity, and extreme environmental conditions – renders them especially vulnerable to anthropogenic disturbances. …

Women's Involvement In Fisheries Co-Management Of The World's Largest Desert Lake, Turkana, Kenya, Maurice O. Ogoma, Judith C. Koskey

Journal of Bioresource Management

Despite their significant presence in the fisheries workforce, women's roles are often less recognized compared to men's. This study investigated the participation of women in beach management units (BMUs) and fisheries activities in Lake Turkana, the world’s largest permanent desert Lake. Data were collected from 200 women respondents across eight purposively sampled BMUs, focusing on gender representation, leadership roles, participation in fisheries activities, factors influencing participation, and strategies for promoting gender equity. Descriptive statistical analysis was conducted to provide an in-depth understanding of women's involvement in fisheries activities. Findings indicated that while gender representation aligned with Kenya's constitutional one-third gender …

Tourism Carrying Capacity At Petungkriyono Forest And Its Supporting Areas, Nurwidya Ambarwati

Journal of Environmental Science and Sustainable Development

Supported by a variety of diversity and landscapes, the development of tourism in the Petungkriyono area is growing rapidly. Optimizing ecotourism services in the Petungkriyono forest without disrupting the ecosystem and damaging the environment can be done by limiting the number of visitors at tourism sites. This study aims to find out information about the tourism capacity of some tourist attractions in the local forest. This study uses the Cifuentes model to predict the maximum number of visitor capacities that can be accommodated in a tourist attraction called Physical Carrying Capacity (PCC), Real Carrying Capacity (RCC), and Effective Carrying Capacity …

Chiropterophagy By The Siberian Weasel (Mustela Sibirica): The First Record In The Russian Far East, Valeriya E. Omelko, Mikhail P. Tiunov

International Journal of Speleology

Chiropterophagy is a widespread phenomenon, but only one case of bat consumption by sable has been documented in the Russian Far East. This study presents the first recorded instance of chiropterophagy by the Siberian weasel (Mustela sibirica) in the southern Russian Far East, based on excrement collected from the Solyanik Cave in the southern Sikhote-Alin Mountains in 2007. The excrement included bones from three bat species (Murina hilgendorfi, Myotis bombinus, Plecotus ognevi) and one vole species (Myodes rutilus). Our findings suggest that the Siberian weasel visits caves during the cold season, although …

Seasonal Occupancy Of The Thermal Plume Of A Spring Tributary To The South Fork Roanoke River, Virginia., Steven L. Powers, Michael M. Calvert, Charlotte M. Spaulding

Southeastern Fishes Council Proceedings

Detection of temperate stream fishes varies widely across seasons as streams teeming with life in summer often appear empty during winter sampling efforts. While much literature documents the disproportionate use of the thermal plumes of spring tributaries by cold water fishes during summer, few studies have investigated occupancy of those habitats by warm water fishes in winter. We conducted quantitative snorkeling observations within the near uniform temperatures (10-14^oC) of the thermal plume of a spring tributary to the South Fork Roanoke River across seasons and compared number of fishes observed and species richness to control observations made just …

Scorpiops Reini Sp. N. From Yunnan, China (Scorpiones: Scorpiopidae), Victoria Tang

Euscorpius

Scorpiops reini sp. n. is described from Yingjiang County (Dehong Prefecture, Yunnan Province) based on an adult pair. It can be readily discriminated from all of its congeneric geographic neighbors in Yunnan, namely S. jendeki Kovařík, 1994, S. shidian (Zhu et al., 2005), S. tongtongi Tang, 2022, and S. zhangshuyuani (Ythier, 2019). Within Yunnan, it resembles S. validus (Di et al., 2010) and S. yangi (Zhu et al., 2007) most, but can be identified by its large median ocelli (relative to the width of ocular subislet), pedipalp chelal finger morphology and pectinal tooth count.

Re-Indigenizing And Collaboratively Tending Urban Greenspaces, Divinity Nnenne Adewale

University Honors Theses

This work details the active process of land tending with the intention of re-Indigenization in the Pacific Northwest at several Portland sites; The Native American Student Community Center, PSU Oak Savanna, and the Ridgefield National Wildlife Refuge. Land tending is an intuitive process, one rooted in love and respect for life of all forms as well as becoming the perpetual student; land tending is not a skill to be mastered, only practiced. Unlike environmental management, tending cannot be done separate from the earth, in a classroom or otherwise. Connections are what tending is built on top of: the foundation; effort …

Star-Studded Stingers: Fluorescent Sensilla On The Scorpion Aculeus (Arachnida: Scorpiones), Graeme Lowe

Euscorpius

The aculeus of the scorpion telson was studied by UV fluorescence microscopy. Numerous brightly fluorescent punctae were observed on the non-fluorescent distal aculeus, including the tip region. The punctae were identified as aculear sensilla coeloconica (ASC), and were connected to fluorescent canals running through the cuticle. ASC were present in both sexes, and in adults and immatures as early as the second juvenile instar, but were absent from the first instar. The distal aculeus was found to be encased in a thick, non-fluorescent dark exocuticle (DX), covering an underlying thin, fluorescent hyaline exocuticle (HX). Fluorescent ASC were recorded from 183 …

Study Of The Brain Anatomy Of Three Extinct Marsupials: Thylacinus Cynocephalus, Thylacoleo Carnifex, And Silvabestius Johnnilandi, Francisco Garcia

Honors Program Theses and Research Projects

Marsupials are pouched mammals that today are mainly found in Australasia and South America. Marsupials have proven to be quite intriguing to evolutionary biologists who note how some marsupials resemble placentals in anatomy due to convergent evolution, with both marsupials and placentals filling similar niches in their respective environments. As of today, studies interested in marsupial brain evolution have published descriptions of cranial endocasts for several species of marsupials, with the number of descriptions seeing a massive boost over the last 20 years with the arrival of CT imaging technology. However, no comprehensive study of brain evolution in marsupials has …

Spatiotemporal Patterns In Orbicella Faveolata Wound Regeneration As An Indicator Of Colony Health, Alexander G. Wheeler

All HCAS Student Capstones, Theses, and Dissertations

Anthropogenic (e.g. damage from anchors, scuba divers, tissue sampling) and natural disturbances (e.g. predation, storm damage) can result in wounding of live tissue on coral colonies. Wounding has been shown to detract from a common resource pool, increasing disease susceptibility and impairing coral growth and reproductive activity. Regeneration not only varies between species, but also between conspecifics in the same location. A colony’s capacity to regenerate tissue can be an indicator of a colony’s condition and resilience. Understanding the physiological and environmental factors that affect tissue regeneration alongside the ultimate impact of sampling (disease and predation correlations) are needed for …

The methods employed to investigate the transition to organic vineyards include qualitative and quantitative approaches, such as interviews with vintners and data analysis of annual crop yields and the economic impact of certified organic vineyards in Napa Valley. The investigation reveals that vineyard proprietors face significant early challenges, including a steep …

Finding Them Before They Find Us: Solving The Emerging Infectious Disease Crisis, Daniel R. Brooks

MANTER: Journal of Parasite Biodiversity

The human population grows daily, it’s on the move, and it’s carving a deep technological footprint on our planet. We alter landscapes and perturb ecosystems, inserting ourselves and other species into novel regions of the world, leading to potentially irreversible changes in the biosphere. This is not news. More than 75 years ago, Charles Elton, one of the founders of modern ecology, wrote, “We must make no mistake; we are seeing one of the greatest historical convulsions in the world’s fauna and flora.” We are also in the midst of a public health and epidemiological crisis. Climate change alters movements …

The Puzzling Distribution Of Platphalonidia Aenigmana, New Species, From The Western U. S. A. And Colombia (Lepidoptera: Tortricidae: Cochylina), John W. Brown

Insecta Mundi

Platphalonidia aenigmana Brown, new species (Lepidoptera: Tortricidae), is described and illustrated from Arizona, California, and Oregon, U. S. A. and Colombia, South America. The new species has been reared on numerous occasions from Garrya elliptica Dougl. ex Lindl. (Garryaceae) in northern California and Oregon, once on Arctostaphylos sp. (Ericaceae) in southern California, and once on Gomphrena globosa L. (Amaranthaceae) in Colombia. Various hypotheses are explored to explain the unusual disjunct geographic distribution of the species. In addition, Phalonidia bassii Razowski (Tortricidae) is transferred to Saphenista Walsingham, resulting in Saphenista bassii (Razowski, 1999), new combination.

A New Species Of Cymatodera Gray (Coleoptera: Cleridae) From Central Arizona, Jacques Rifkind

Insecta Mundi

Cymatodera campbelli, new species (Coleoptera: Cleridae), is described from central Arizona, United States. Though superficially similar to several other small species of Southwestern Cymatodera Gray that are commonly collected at lights, this apparently rare species has distinctive coloration and surface sculpturing. Its discovery suggests that systematic collecting even in areas that have historically attracted entomological attention may still yield additions to our fauna.
