Multi-season Observational Study of the Thermodynamic, Kinematic and Precipitation Structures within Flooding and Typical Storms in the Oregon Cascades
… of single parameters and the combination of multiple parameters. All flooding storms were associated with land-falling atmospheric rivers, deep rain layers, strong cross-barrier flow, and long durations of precipitation. Flow being multi-layered with the presence of shear is shown to have a …

Determining habitat and biotic factors driving puma (<i>Puma concolor</i>) space use and underlying dynamic processes (colonization and extinction) over 20 years in protected and private areas throughout Belize, Central America
… and habitat. We used single-species, single-season and multi-season occupancy modeling to explore factors influencing distribution and persistence of pumas across the country of Belize. We used camera trapping data from 7 protected areas over 20 years with 2,198 camera stations covering …

What lies beneath--discovering the hidden story of plant roots: root growth strategies of wetland plants in northern Ontario along a gradient of growing season length.
Root growth strategy can be classified as multi-season (winter-surviving) or single-season (fallsenescing). This study investigated the relationship of wetland plant species with multi-season roots (sMSR) and species with single-season roots (sSSR) to soil temperature across a climatic growing …

Injury risk and performance: Towards a better understanding of the complexities and intricacies of load monitoring within an elite football club
… Professional sports teams, cognizant of the multifaceted implications of inadequate load management, have invested significantly in this domain. In the realm of soccer, where injuries can lead to prolonged player absences, impacting team performance and incurring substantial financial costs, …

The influence of habitat features and co-occurring species on puma (Puma concolor) occupancy across eight sites in Belize, Central America
… is particularly lacking. I used single- and multi-season, single-species occupancy models and two-species co-occurrence models to analyze camera trapping and habitat data collected at eight study sites across Belize. Puma occupancy was positively influenced by jaguar trap success, understory …

An assessment of factors influencing territory size and the use of hunter surveys for monitoring wolves in Montana
… gray wolves (Canis lupus). I evaluated whether a multi-season patch occupancy model (POM) could be used to accurately estimate the abundance and distribution of wolf packs in Montana from 2007 to 2009. I evaluated hunter sightings of wolves as an index of occupancy and assessed model accuracy by …

Multi-scale analysis of urban wetland changes using satellite remote sensing techniques
… scales. Not many studies fully addressed multi-scale urban wetland-cover dynamics in both the temporal and spatial dimension. The objective was to understand how major driving factors - human disturbances and climate variation - impacted urban wetlands as determined by the scale effects of …

BRIDGING AQUATIC AND TERRESTRIAL ECOSYSTEMS: ECOLOGY OF SEMI-AQUATIC MAMMALS IN SOUTHERN ILLINOIS
… third of Illinois (44,526 km2) to estimate multi-season occupancy. Each survey unit was a 400-m stream segment visited twice by 2 observers for a total of 4 observations per site per period. Observers recorded all mammal signs found, including sign species and type. Sites were Intensive …

Spatial population dynamics of recolonizing wolves in the Western Alps
… (0.82 ± 0.04).<p> I applied an unconditional multi-season occupancy model to estimate wolf occupancy dynamics. Human disturbance (β = -5.553, SE = 2.186) and rock-area cover (β = -4.129,<p> SE = 1.392) had negative effects on occupancy, while the presence of red deer (β = 0.694, …

Exploring Participation in Citizen Science for Leadership Identity Development and Food Systems Leadership: A Case Study of Tricot
… its presence in the community, and its multi-season engagement solidified the leadership identity construction process. Further, the findings revealed that Osun state tricot farmers exercised food systems leadership by: (1) strengthening seed systems via influence; (2) advancing value …

Occupancy and Abundance of Golden-cheeked Warblers (Dendroica chrysoparia) on the Balcones Canyonlands Preserve
… each site. Count data were analyzed using both multi-season occupancy models and binomial mixture models (BMM) to estimate each observer's probability of detection at both the species and individual level. Model selection revealed that observer had a strong influence on detection of GCW A. I …

Ecology of the marsh rice rat (Oryzomys palustris) in southern Illinois: wetland dynamics, metapopulations, and trophic position
… and 14 patches at a reclaimed mineland. I used multi-season occupancy modeling to estimate initial occupancy, detection, colonization and extinction rates. Catch per unit effort differed markedly between the 2 sites (27 captures/1,000 trap-nights at the floodplain site vs. 8 at the mining site). …

Effects of non-native woody plant species on shrubland birds of conservation concern

FACTORS INFLUENCING THE SPATIAL AND TEMPORAL STRUCTURE OF A CARNIVORE GUILD IN THE CENTRAL HARDWOOD REGION
… habitat data for each camera-cluster. In a multi-stage approach, I used information-theoretic methods to develop and evaluate models for detection, species-specific habitat occupancy, multi-species co-occupancy, and multi-season (colonization and extinction) occupancy dynamics. I developed …

Effects of temperature and food availability on the reproductive ecology of an arid-zone bird
… data from two very different summer breeding seasons: a hot and dry breeding season (2019/20) and a cool and very wet breeding season which included a 1-in-100-year flooding event (2020/21). During an earlier year of the study (2018/19), drought conditions were so extreme that no hornbills …
