Human–Wildlife Interactions

The common chameleon (Chamaeleo chamaeleon) is a threatened species in Spain. The loss and transformation of their traditional habitats are among the main causes of its decline. Linear infrastructures, such as roads and highways, cause direct habitat loss, roadkill, and fragmentation of populations by acting as an artificial barrier. In this study, we investigated the potential effect of 2 high-speed road infrastructures in southern Spain on local populations of common chameleons. A total of 34 grids of 1x1 km were sampled, differentiating between grids without road presence (n = 17) and grids with road presence (n …

Dust Management At An Active Construction Area Affects Monarch Distribution, Amy W. O'Donnell, Jeffery D. Sullivan, Carl R. Callahan, Peter C. Mcgowan, Diann J. Prosser

Human–Wildlife Interactions

The North American population of monarch butterflies (Danaus plexippus) is experiencing dramatic declines, necessitating investigations into challenges facing this species that can be resolved through management actions. For instance, dust made airborne by heavy equipment driving along a dirt road can settle on roadside vegetation, resulting in reduced use by monarchs. Dust accumulation on areas where floral nectaries such as leaves, stems, and flowers may be present could reduce the ability of pollinators, such as monarchs, to access nectar from flowering plants needed during migration. One such challenge was observed on Poplar Island, an island restoration project located in …

Drop Retention And Departure In Adiabatic Shear Flow On Structured Superhydrophobic Surfaces, Blake M. Lyons, Daniel Maynes, Julie Crockett, Brian D. Iverson Jan 2024

Drop Retention And Departure In Adiabatic Shear Flow On Structured Superhydrophobic Surfaces, Blake M. Lyons, Daniel Maynes, Julie Crockett, Brian D. Iverson

Faculty Publications

Drops are retained or held on surfaces due to a retention force exerted on the drop by the surface. This retention force is a function of the surface tension of the liquid, drop geometry, and the contact angle between the drop and the surface. When external or body forces exceed the retention force, the drop begins to move. This work explores the conditions for which drop departure occurs on structured superhydrophobic surfaces in the presence of an applied shear flow. Drop departure is explored for five microstructured superhydrophobic surfaces, one nanostructured carbon nanotube surface and one smooth hydrophobic surface. Surface …

In Vivo Human Medial Gastrocnemius Fascicle Behaviour And Belly Gear During Submaximal Eccentric Contractions Are Not Affected By Concentric Fatiguing Exercise, Matheus Daros Pinto, Kazunori Nosaka, Anthony J. Blazevich

Research outputs 2022 to 2026

Changes in muscle geometry and belly gearing during eccentric contractions influence fibre strain and susceptibility to muscle damage. They are modulated by the interaction between connective tissues and intracellular-intrafascicular fluid pressures and external pressures from neighbouring structures. Fatiguing exercise triggers fluid shifts (muscle swelling) and muscle activation changes that may influence these modulators. Our purpose was to measure medial gastrocnemius (MG) geometric changes in vivo during eccentric contractions before and after maximal concentric muscle work to test the hypothesis that fatigue would reduce fascicle rotation and muscle gear and provoke greater fascicle strain. Submaximal eccentric plantar flexor contractions at 40% …
