Bridging Prairie Restoration And Regenerative Agriculture With Compost Tea / The Rocket Incident: Post-Fire Soil Microbe Recovery On The Eastern Washington University Restoration Site, April Hersey Jan 2025

Bridging Prairie Restoration And Regenerative Agriculture With Compost Tea / The Rocket Incident: Post-Fire Soil Microbe Recovery On The Eastern Washington University Restoration Site, April Hersey

EWU Masters Thesis Collection

Inland Pacific Northwest prairie is an endangered ecosystem that has been reduced by conversion to agriculture. There is growing interest in the role of soil microorganisms in prairie ecosystems, which may be crucial for restoration of the plant community through interspecies interactions within the rhizosphere. One method for improving soil microorganism community composition is compost tea: enriched liquid compost extract. Compost tea is used in regenerative agriculture to improve crop yields and protect against pathogens. While research has supported compost tea application in regenerative agriculture, it has not been widely studied in the context of ecosystem restoration. After beginning a …

Shrubsteppe Birds Under Fire: Guiding Post-Wildfire Habitat Restoration In The Whiskey Dick And Quilomene Units, Washington, Kevin Clements Jan 2025

Shrubsteppe Birds Under Fire: Guiding Post-Wildfire Habitat Restoration In The Whiskey Dick And Quilomene Units, Washington, Kevin Clements

All Master's Theses

Bird species, globally, are declining at an alarming rate. Birds of the shrubsteppe are particularly vulnerable to habitat loss caused by agricultural development, invasive vegetation, and heightened wildfire frequency and severity. Fire and invasive vegetation create a positive feedback cycle that threatens complete conversion of shrubsteppe to grasslands. Restoring habitat following wildfire is a top priority for land managers. As bioindicators of ecosystem health, bird populations reflect landscape changes and restoration efficacy. I analyzed bird populations in the Whiskey Dick and Quilomene units of the L.T. Murray Wildlife Area in Kittitas County, Washington following the 2022 Vantage Highway fire. Using …

More Than One Way To Be A Planktivore: The Vast Morphospace Of Plankton-Feeding Reef Fishes, Isabelle Ng, David R. Bellwood, Jan M. Strugnell, Sergio R. Floeter, Alexandre C. Siqueira

Research outputs 2022 to 2026

Planktivorous reef fishes are thought to possess unique morphological traits to feed on small, evasive prey. Despite the multitude of family-level studies addressing this hypothesis, results remain inconclusive. Our goal, therefore, was to determine whether specialised traits and patterns of morphological convergence are congruent across a comprehensive phylogeny of reef-associated fishes. We measured 15 morphological traits from 815 images of 299 species in 12 globally distributed families. Using phylogenetic comparative methods, we mapped the evolution of plankton-feeding across lineages; assessed the effect of planktivory on body shape; and tested for the presence of morphological convergence among planktivores. We demonstrate that …

Seagrasses Are Most Vulnerable To Marine Heatwaves In Tropical Zones: Local-Scale And Broad Climatic Zone Variation In Thermal Tolerances, Nicole Said, Chanelle Webster, Simone Strydom, Natasha Dunham, Matthew P. Adams, Kathryn Mcmahon

Research outputs 2022 to 2026

Under a changing climate, it is imperative that we understand how species may respond to temperature impacts, which can differ among populations of the same species due to local drivers. Thermal tolerance data, which can be used to assess an organism's upper thermal limits, is valuable to identify species and/or populations' susceptibility to thermal stress. This study assessed the variation in thermal tolerance of six seagrass species at both broad latitudinal (c. 500–1000 km) and local scales (c. 25 km). Photosynthesis–temperature curves (15–45°C) were conducted, by measuring oxygen in closed incubation chambers, and thermal optima (Topt) was extracted. We found …

Joint Estimation Of Paternity, Sibships And Pollen Dispersal In A Snapdragon Hybrid Zone, Thomas James Ellis, David Luke Field, Nicholas H. Barton Jan 2025

Joint Estimation Of Paternity, Sibships And Pollen Dispersal In A Snapdragon Hybrid Zone, Thomas James Ellis, David Luke Field, Nicholas H. Barton

Research outputs 2022 to 2026

Inferring genealogical relationships of wild populations is useful because it gives direct estimates of mating patterns and variance in reproductive success. Inference can be improved by including information about parentage shared between siblings, or by modelling phenotypes or population data related to mating. However, we currently lack a framework to infer parent–offspring relationships, sibships and population parameters in a single analysis. To address this, we here extend a previous method, Fractional Analysis of Paternity and Sibships, to include population data for the case where one parent is known. We illustrate this with the example of pollen dispersal in a natural …

Research outputs 2022 to 2026

Epilithic algae dominate cover on coral reefs globally, forming a critical ecological interface between the benthos and reef organisms. Yet, the drivers of epilithic algal composition, and how composition relates to the distribution of key taxa, remain unclear. We develop a novel metric, the Epilithic Algal Ratio, based on turf cover relative to total epilithic algae cover, and use this metric to assess cross-scale patterns. We reveal water quality and hydrodynamics as the key environmental drivers of the Epilithic Algal Ratio across the Great Barrier Reef (GBR), and reefs globally. On the GBR, the abundance of herbivorous fishes and juvenile …

Research outputs 2022 to 2026

Released (or discarded) fish from recreational and commercial line fisheries can experience significant levels of post-release mortality (PRM), affecting sustainability. Although PRM effects are often considered in data-rich (integrated model) assessments, this is uncommon in data-limited assessments. This study investigates impacts of PRM when applying data-limited, length-based assessment methods for four reef-dwelling demersal fish species in temperate Western Australia (Glaucosoma hebraicum, Chrysophrys auratus, Choerodon rubescens and Epinephelides armatus). These species differ considerably in their biology and susceptibility to PRM. For each species simulations were undertaken to (1) evaluate the reliability of a length-based catch curve (LBCC) method for estimating fishing …

Research outputs 2022 to 2026

Recent advances in microCT are facilitating the investigation of microstructures in spiders and insects leading to an increased number of studies investigating their neuroanatomy. Although microCT is a powerful tool, its effectiveness depends on appropriate tissue preparation and scan settings, particularly for soft, non-sclerotized tissues, such as muscles, organs, and neural tissues. As the application of microCT in spiders is only in its infancy, published protocols are often difficult to implement due to substantial size variation of the specimens. The present study was initiated to determine how to account for this variation. Our work builds on previous methods using microCT …

Research outputs 2022 to 2026

The social brain hypothesis predicts that the relative size of specific brain regions is driven by the cognitive capacity required to manage complex (social) situations. Spiders are intriguing models to test this hypothesis, as sociality is rare in this usually solitary and aggressive group. Here, we used microCT to compare the central nervous system and brain volumes between social and solitary females of the species in two taxonomic groups, huntsman and crab spiders. Overall, we found no difference in relative CNS and brain volume between social and solitary species. However, social huntsman spiders Delena cancerides had larger arcuate and mushroom …

Predator Exposure And Gene Flow As Tools To Preserve Antipredator Traits In Havened Populations: Behavioural Observations Of Quenda, Natasha D. Harrison, Nicola J. Mitchell, Harriet Mills, Anna J.M. Hopkins, Ben L. Phillips

Research outputs 2022 to 2026

When predation pressure is relaxed, for example, in predator-free conservation havens, populations can rapidly lose antipredator traits. Such trait loss is thought to be accelerated when resource competition becomes the dominant selection pressure in the absence of predation risk. Under these circumstances, antipredator traits may be retained by reducing resource competition through predator exposure (both of which reduce selection against antipredator traits) or by maintaining gene flow with predator-savvy populations. Here, we examine differences in antipredator traits in quenda, Isoodon fusciventer, inside and outside of a conservation haven in which low levels of gene flow and predator exposure have been …

The Australian EEZ provides habitat for ten species of mysticete whales seasonally supporting critical life functions ranging from feeding to breeding. All of these species produce downsweeping calls, which may confound passive acoustic monitoring efforts. In an attempt to optimize a detector for Eastern Indian Ocean pygmy blue whale (EIOPBW) downsweeps, we tried a spectrogram correlator based on confirmed templates and a neural network trained on general blue whale D-calls followed by clustering algorithms. Outputs were manually validated by bioacousticians. We found that downsweeps exhibit significant variability and form a graded continuum of acoustic features, as opposed to clusters. Comparative …

Detection Of Vkorc1 Single Nucleotide Polymorphisms Indicates The Presence Of Anticoagulant Rodenticide Resistance In Australia's Introduced Rats, Alicia F. Gorbould, Quinton F. Burnham, Michael T. Lohr, Annette Koenders

Research outputs 2022 to 2026

BACKGROUND: Anticoagulant rodenticides (ARs) are used globally to manage pest rodent populations. However, resistance to ARs in target rodent populations challenges pest control efforts and can increase risks to nontarget species. Resistance is frequently associated with nonsynonymous single nucleotide polymorphisms (nsSNPs) in the Vkorc1 gene, and this study carried out the first Vkorc1 survey of introduced rats on the Australian mainland. RESULTS: We identified three species of introduced rat using the cytochrome b gene across Brisbane, Melbourne, Perth and Sydney: Rattus rattus (Linnaeus 1758) (Lineage I); Rattus norvegicus (Berkenhout 1769); and Rattus tanezumi (Temminck 1844) (Lineage II).

Research outputs 2022 to 2026

Jasmonic acid (JA) and its methyl ester, methyl jasmonate (MeJA), are increasingly being recognised as unique phytohormones, linked to a variety of physiological and molecular functions. Endogenous concentrations of jasmonates (JAs) vary among plant parts, stages of fruit development, maturity, ripening and during the postharvest period. MeJA expresses prime cellular responses, where as an elicitor of secondary metabolite production, aids in inter-plant communications, regulates the biosynthesis of associated phytohormones, supports plant defence systems against pathogenic infections, and helps in abiotic stress conditions. The potential of MeJA has been extensively studied in modulating fruit ripening, enhancing colour development, and improving the …

Research outputs 2022 to 2026

Building a comprehensive understanding of geo-ecological functions is viewed as a critical step in the quantification of carbonate and sediment budgets on coral reefs. Although parrotfishes are known to play key roles in such functions, the roles of surgeonfishes are less well understood. This is despite surgeonfishes being some of the largest and most abundant, nominally herbivorous fishes on reefs, with the potential to play a major role in sediment dynamics. Here, we quantified the role of four focal surgeonfish species across two functional groups (sediment suckers and brushers) in cross-habitat sediment dynamics by combining data on behavioural observations, fish …

A literature review was undertaken, and data on received levels at the animal when certain types of responses were observed were compiled in an online supplementary spreadsheet. Based on this, an overview of responses was written, organized first by species and then by sound type. In-air and underwater sound sources were considered. The most studied sound types were mid-frequency sonar and acoustic deterrent devices and then impact pile driving and vessels. The most frequently reported response was avoidance, followed by changes in swim …

Samples of the ariophantid genera Oxytesta, Bensonies, Himalodiscus, Ariophanta, Khasiella, and Sesara collected in Bhutan are treated. For all species distributional data for the kingdom are summarized on maps. Shells are described and figured on the basis of specimens from Bhutan, with radulae and genital tracts whenever possible. Six Oxytesta species are dealt with, 3 of which new to science, viz. O. delicata E. Gittenberger & Sherub, O. dubitata E. Gittenberger & Kezang Tobgay, and O. lhuentsensis E. Gittenberger & Sherub. Five Bensonies species are recognized, one of which could not be identified and 4 are described as new, viz. …

Research outputs 2022 to 2026

This study evaluated the phytoremediation potential of pot marigolds on green wall systems for removing soil cadmium. The experiment was a factorial arrangement in a randomized complete block design. The first factor was cadmium (0, 1, 2, and 3 mg/kg soil), and the second was seven single or mixed plant growth-promoting rhizobacteria (PGPR) and the control treatments. All root and flower-related traits significantly increased after bacterial treatments (p ≤ 0.05). Substrates inoculated with Thiobacillus thioparus strain 300, Mix2 (Aztobactor chorococcum strain D0941 + Azosporillum liposferum strain So131), and Mix3 (Thiobacillus thioparus strain 300+ Pseudomonas putida strain G0951+ Aztobactor chorococcum strain …
