This study was conducted to determine and evaluate the heavy metal concentrations levels: lead (Pb), cadmium (Cd), and mercury (Hg) in the meat of some commercial fish species: Grouper (Epinephelus areolatus), Emperor (Lethrinus nebulosus) and Cuttlefish (Sepia Pharaonis). A total of 84 fish samples were caught and collected from different sites in the Gulf of Aden and the Arabian Sea between January 2020 and December 2022. Some of them were sold in the cities markets of Hadhramout governorate- Yemen, and some of them were exported abroad. All samples were analyzed at the laboratories of the Faculty of Environmental Sciences and …
The Introduction Of Nursery Seedlings And Their Fungi To A Spruce-Fir Forest In Newfoundland, 2023 Western University
The Introduction Of Nursery Seedlings And Their Fungi To A Spruce-Fir Forest In Newfoundland, Alicia G. Banwell
Electronic Thesis and Dissertation Repository
A few species of boreal trees form symbiotic relationships with many ectomycorrhizal (ECM) fungi that allow trees to thrive on nutrient poor soils in Canada. A small number of ECM species grow on tree seedlings raised in nurseries for reforestation of clearcut sites. The native ECM fungal community composition of a mixed spruce-fir forest in Newfoundland was determined through next generation sequencing. With the introduction of nursery seedlings, the transfer of native ECM fungi to seedlings and nursery-established ECM fungi to roots was investigated over 20 months. ECM community composition was found to be similar to that of other boreal …
Twelve Wallace Myths, 2023 Western Kentucky University
Twelve Wallace Myths, Charles H. Smith
Faculty/Staff Personal Papers
Alfred Russel Wallace’s (1823-1913) bicentennial year is a good time to take stock. In this presentation I discuss twelve Wallace-related issues that I feel have been poorly taken up. These range from the biological to the biographical, including subjects such as social criticism, human evolution, autobiographical memory, natural selection, national affinities, spiritualism, and wokeism.
Fusion Of Pectinal Teeth In Scorpio Kruglovi Birula, 1910 (Scorpiones: Scorpionidae), 2023 Marshall University
Fusion Of Pectinal Teeth In Scorpio Kruglovi Birula, 1910 (Scorpiones: Scorpionidae), Ersen A. Yağmur, Gülhanım Yağmur
Euscorpius
A rare teratological anomaly of pecten is described and illustrated: a case of fusion in pectinal teeth in the scorpion Scorpio kruglovi Birula, 1910). It was observed that 7th and 8th teeth are fused in the right pecten. The resulting fused tooth is larger than other teeth. A smaller fulcrum located inside of the large, fused tooth whereas other fulcra are located between normally developed teeth.

Highly pathogenic avian influenza viruses (HPAIVs) of subtype H5 of the Gs/GD/96 lineage remain a major threat to poultry due to endemicity in wild birds. H5N1 HPAIVs from this lineage were detected in 2021 in the United States (US) and since then have infected many wild and domestic birds. We evaluated the pathobiology of an early US H5N1 HPAIV (clade 2.3.4.4b, 2021) and two H5N8 HPAIVs from previous outbreaks in the US (clade 2.3.4.4c, 2014) and Europe (clade 2.3.4.4b, 2016) in chickens and turkeys. Differences in clinical signs, mean death times (MDTs), and virus transmissibility were found between chickens and …

Understanding how tropical systems have responded to large-scale climate change, such as glacial-interglacial oscillations, and how human impacts have altered those responses is key to current and future ecology. A sedimentary record recovered from Lake Junín, in the Peruvian Andes (4085 m elevation) spans the last 670,000 years and represents the longest continuous and empirically-dated record of tropical vegetation change to date. Spanning seven glacial-interglacial oscillations, fossil pollen and charcoal recovered from the core showed the general dominance of grasslands, although during the warmest times some Andean forest trees grew above their modern limits near the lake. Fire was very …
Incorporating Biodiversity-Ecosystem Function Relationships Into Models And Conservation Planning, 2023 University of Massachusetts Amherst
Incorporating Biodiversity-Ecosystem Function Relationships Into Models And Conservation Planning, Sarah R. Weiskopf
Doctoral Dissertations
Unsustainable use of nature and climate change are leading to unprecedented biodiversity declines. These declines have cascading impacts on ecosystem function and ecosystem services, and ultimately on human well-being. International agreements have been adopted that aim to address both crises. The Paris Agreement, adopted in 2015, set global emission reductions targets. In 2022, most countries agreed to the Kunming-Montreal Global Biodiversity Framework (GBF). The GBF sets 23 ambitious targets for 2030 ranging from reducing threats to biodiversity, meeting people’s needs through sustainable use and benefit sharing, and solutions for implementation.
Although adopting global goals and targets is an important first …
The Discovery Of A Novel Bacteria From A Large Co-Assembly Of Metagenomes, 2023 University of Massachusetts Amherst
The Discovery Of A Novel Bacteria From A Large Co-Assembly Of Metagenomes, Matthew Finkelberg
Masters Theses
In the summer of 2022, a co-assembly of metagenome was created using the microbes found at Barres Woods in Harvard Forest. 14 samples were taken, and sample was split into the organic and mineral layer, which totals 28 Bulk MAGs. Within this Co-assembly, 4 different genomes were found which were designated with the phylum of FCPU426. Three of which were considered medium quality and one being assigned high quality. The novel phyla first appeared in NCBI and GTDB databases in June 2018. The name FCPU426 dates to 2010 and was named based on the 16s amplicon sequencing.
The novel phylum …
Climate Change Attitudes Of United States Family Forest Owners And Their Influence On Forest Management Practices, 2023 University of Massachusetts Amherst
Climate Change Attitudes Of United States Family Forest Owners And Their Influence On Forest Management Practices, Logan Miller
Masters Theses
Understanding family forest owners’ (FFOs’) attitudes and behaviors towards climate change will allow for more sustainable forest management practices to be implemented, helping to combat climate change and its impacts. The goals for this research are (1) to begin measuring U.S. FFO attitudes toward climate change, (2) to determine what factors impact these attitudes, and (3) to determine how they influence the FFO’s management practices using the Responsible Environmental Behavior (REB) framework (Hines et al. 1987). Chapter 1 explores the different facets of my thesis project focusing on forests and forests’ ecosystem services, forest ownership in the United States, and …

Brown Anole (Anolis Sagrei) Hoxa5: Insights Into The Divergence Of Hoxa5 Gene Expression And Regulation Across Evolutionarily Divergent Gnathostome Vertebrates, Jennifer A. Lange, Amber L. Rittgers, Adam Davis
Georgia Journal of Science
Hox genes are evolutionarily conserved developmental regulatory genes that function, in part, to pattern the anterior-posterior (AP) axis of organs and organ systems during animal embryonic development. Hoxa5, specifically, is shown to be expressed in the spinal cord, somites, or transient compartments giving rise to the vertebrae and ribs, developing gut, lungs, and limbs of the mouse (Mus musculus). The cis-regulatory elements (CREs), or short DNA sequences, that direct Hoxa5 expression in these embryonic domains have been mapped and functionally tested in the mouse as well. Similar Hoxa5 expression patterns have been observed in chicken ( …

Raccoon Spatial Ecology In The Rural Southeastern United States, Jacob E. Hill, Madison L. Miller, James L. Helton, Richard B. Chipman, Amy Gilbert, University Of Georgia, Guha Dharmarajan, Olin E. Rhodes Jr.

The movement ecology of raccoons varies widely across habitats with important implications for the management of zoonotic diseases such as rabies. However, the spatial ecology of raccoons remains poorly understood in many regions of the United States, particularly in the southeast. To better understand the spatial ecology of raccoons in the southeastern United States, we investigated the role of sex, season, and habitat on monthly raccoon home range and core area sizes in three common rural habitats (bottomland hardwood, upland pine, and riparian forest) in South Carolina, USA. From 2018–2022, we obtained 264 monthly home ranges from 46 raccoons. Mean …
