There has been continuous and growing interest in edible insects. Worldwide, various levels of insect farming are emerging, ranging from small domestic farms to vertical farms reaching heights of 36 meters, accommodating several million growing insects. The appeal of insects lies in their ecological benefits, as they contribute to the valorization of unde-rutilized organic residues while requiring minimal space and water. The selection of insect species is influenced not only by their biology and behavior but also by local preferences and customs, varying with the scale of production and geographi-cal location. This review article aims to provide an updated overview …

The Effects Of Native Perennial Cover On Physiological Indicators Of Habitat Quality For Sparrows In California Coastal Prairie Rangelands, Madeleine A. Ybarra

Cal Poly Humboldt theses and projects

Prescribed grazing management can have myriad effects on wildlife, with low to moderate grazing being associated with an increased abundance of some grassland birds. Specifically, Grasshopper Sparrow (Ammodramus savannarum) and Savannah Sparrow (Passerculus sandwichensis) abundance have been shown to be positively associated with both grazing and a higher percentage of native plant cover. However, measures of abundance provide an incomplete assessment of habitat quality for birds. Physiological and morphological measurements can help indicate environmental stress in individual birds, which reveals more information about habitat quality. We measured body condition and heterophil:lymphocyte ratios to gauge avian stress …

Escarpments Within Mediterranean Seagrass Posidonia Oceanica Meadows Increase Habitat Heterogeneity And Structural Complexity Enhancing Fish Diversity And Biomass, Enric Gomis, Enric Ballesteros, Irene Bernabeu, Karina Inostroza, Miguel A. Mateo, Oscar Serrano

Research outputs 2022 to 2026

Seagrass meadows provide important ecosystem services including carbon sequestration, coastal protection from erosion, and sustained biodiversity and fisheries thereby improving the wellbeing and livelihoods of coastal communities. The erosion of millenary deposits of intertwined roots and rhizomes of Posidonia results in the formation of three-dimensional structures named escarpments that constitute a biogenic reef habitat. However, the natural history of seagrass escarpments including their formation processes and their role as habitat for reef fauna and flora remains poorly understood. This research located and characterized Posidonia oceanica escarpments in Menorca (Balearic Islands) and compared structural complexity and fish assemblages among seagrass escarpments, …

Gómez-Aparicio, B. J. Graae, S. Kuś, S. Lindmo, A. Orczewska, F. Rodríguez-Sánchez, P. Vangansbeke, T. Vanneste, M. E. Hanley

School of Biological and Marine Sciences

In addition to well-known effects on species ecophysiology, phenology, and distributions, climate change is widely predicted to impact essential ecosystem services such as decomposition and nutrient cycling. While temperature and soil moisture are thought to influence litter decomposition, elucidating consistent soil process responses to observed or predicted shifts in climate have proven difficult to evidence. Here we investigated how aspect (i.e., north-south orientation), a natural model for variation in soil temperature, influenced soil physico-chemical conditions and decomposition of two standardised litter types (Green tea and Rooibos teabags) in Pole-facing (PF) and Equator-facing (EF) roadside verges spanning a 3000 km and …

Inconsistent Bioreceptivity Of Three Mortar Mixes In Subtidal Sites, Jessica R. Bone, Alice E. Hall, Rick Stafford, Roger J.H. Herbert

School of Biological and Marine Sciences

Concrete is extensively used in coastal engineering and development which, in addition to its high carbon footprint, threatens intertidal habitats and ecosystems. Eco-engineering addresses this by designing habitat features into coastal infrastructure. The chemical bioreceptivity of cement has been shown to vary, but ordinary Portland cement is generally considered to be the least bioreceptive. In this study, we compare two low carbon mortars (a natural, single source cement (VP), and an ordinary Portland cement/ ground granulated blast furnace slag blend (GGBS)) with an ordinary Portland cement-based control mix (OPC). The three mortars were made into smooth blocks which were secured …

Examining The Role Of Microbial Communities In Soil Carbon Cycling Across Levels Of Complexity, Chansotheary Dang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Microorganisms provide the foundation for many ecosystem processes and are important drivers of carbon and nutrient cycling. The advancement of next generation sequencing has allowed researchers to lift open the lid on the ‘black box’ in microbial ecology. While previously unculturable microbes can now be characterized with the 16S rRNA gene, answering ‘who’s there?’ is only part of the challenge. Hidden inside the ‘black box’ remains the question, ‘who’s doing what?’. Recent development in trait-based methods like quantitative stable isotope probing (qSIP) equipped microbial ecologists with the tool to connect taxon-specific traits to ecosystem processes. Despite the growing body of …

Measures Of Feed Efficiency In Beef Cattle: Biological Basis And Effect On Response To Dietary Supplementation, Modoluwamu Idowu

Graduate Theses, Dissertations, and Problem Reports (ETD)

During the feedlot receiving period, newly weaned beef cattle face various stressors, including weaning, transportation, vaccination, and exposure to pathogens. Additionally, changes in diet and low dry matter intake contribute to nutrient deficiencies, heightening susceptibility to disease and performance declines. Therefore, we examined the effects of dietary supplementation with a multicomponent blend of prebiotics and probiotics on the health, immune status, metabolism, and performance of newly weaned beef steers during a 35-day receiving period. Our results showed that compared to the control group, the supplemental additive (SYNB) increased average daily gain (ADG), dry matter intake, and meal events during the …

Development And Implementation Of Occupational Therapy Group Protocols For Individuals In Recovery For Substance Use Disorder: Considering Social Determinants Of Health And Occupational Areas Of Need, Samantha Jane Windisch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Substance use disorders (SUDs) are becoming a more widespread issue globally. According to the National Survey on Drug Use and Health, 19.7 million adults in the U.S. suffered from an SUD in 2017.

Articles

Background: Most government efforts to control the COVID-19 pandemic revolved around non-pharmaceutical interventions (NPIs) and vaccination. However, many respiratory diseases show distinctive seasonal trends. In this manuscript, we examined the contribution of these three factors to the progression of the COVID-19 pandemic. Methods: Pearson correlation coefficients and time-lagged analysis were used to examine the relationship between NPIs, vaccinations and seasonality (using the average incidence of endemic human beta-coronaviruses in Sweden over a 10-year period as a proxy) and the progression of the COVID-19 pandemic as tracked by deaths; cases; hospitalisations; intensive care unit occupancy and testing positivity rates in six …

Sediment Sorting Within A Relatively Wave-Exposed And Sandy Subtidal Seagrass (Zostera Marina) Meadow, Gerd Masselink, Tom Brown, Tim Scott, Liane Brodie

School of Biological and Marine Sciences

Seagrasses impact on sedimentary intertidal and subtidal ecosystems by affecting local hydrodynamics, geomorphology and sediment properties. Their influence on hydrodynamics is to reduce flow velocities in their canopies, and this leads to increased net sedimentation rates and reduction of the grain size. Most investigations of the seagrass-hydrodynamics-sediment feedback system has been carried out over silt and fine-sand beds under tide-dominated conditions, mostly in the intertidal zone. Here, we use sedimentological data from a relatively wave-exposed and subtidal seagrass (Zostera marina) meadow in the Isles of Scilly with a fine-to-medium sand bed and show that the sand within the seagrass meadow …

We argue that the integration of research with planning tools is key to achieving environmental planning and development that …

Using Multi-Spectral Satellite Data For Mapping Bathymetry Of Bitter Lakes, Suez Canal, Asmaa H. Mohammed, Sarah S. Abdel-Hamid, Hozaifa S. Ibrahim, Esraa E. Abouelmaaty

Blue Economy

The Suez Canal runs through an important water body, the Bitter Lakes which are deepened regularly to suit passing by or parking vessels of different drafts. The bottom topographic is dynamically changing due to sedimentation by ships and water current movements that are usually impacting and requiring those continuing dredging processes performed by the Suez Canal Authority. Basically, studying the bottom dwellers of any lake requires bathymetric data which is very costly. Therefore, bathymetry maps can be derived from passive optical satellite sensors (multispectral). The present study used Landsat-8 and Sentinel-2 satellite imagery to produce water depth of the Bitter …
