The Use of Tonometry as a Diagnostic Tool to Evaluate Intraocular Pressures in Normal and Abnormal California Sea Lion EyesMejia-Fava, Johanna del Carmen 13 December 2014 (has links)
Ocular disease is one of the most common problems encountered in sea lions at various zoos and aquariums around the world.1 The California sea lion (Zalophus californianus) is one of the most common marine mammals maintained in zoos and is also the most commonly afflicted with ocular disease. Studies have shown that pinnipeds housed in captivity manifest an array of ocular lesions.2 Eye disease can range from a pinpoint corneal opacity to loss of vision due to keratopathy, cataracts and secondary glaucoma. Glaucoma is a disease that has not been extensively studied in the sea lion.3 Observation of clinical signs and determination of intraocular pressures (IOP) are critical for early diagnosis. IOP measurement may elucidate intraocular disease and provides information on the balance between aqueous humor production and outflow. The objective of this study is to measure IOP in California sea lions that have clinically normal eyes as well as those with varying degrees of ocular diseases, and to evaluate the incidence of secondary glaucoma in this species.

Distribution et structure des communautés zooplanctoniques dans deux écosystèmes côtiers. : Analyse de l'impact des facteurs physiques et trophiques sur les distributions spatiales et les spectres de taille du zooplancton.Espinasse, Boris 27 June 2012 (has links)
La structure de taille et la distribution spatiale du zooplancton ont été étudiées dans deux écosystèmes : une baie de la côte Ouest de la péninsule antarctique et le golfe du Lion en mer méditerranée occidentale. L'acquisition des spectres a été permise par l'utilisation de deux capteurs optiques : le ZooScan / ZooProcess et le Laser Optical Plankton Counter (LOPC). L'impact de différents types de forçages sur les spectres de taille des communautés zooplanctoniques a été mis en évidence dans les deux écosystèmes côtiers, notamment grâce aux caractéristiques des spectres de biomasse normalisée. Le long de la péninsule Antarctique, la fin de l'automne est une période charnière à tous les niveaux trophiques avec la baisse de la production primaire et l'agrégation du krill (Euphausia superba) dans les baies continentales. Les données ADCP ont permis de localiser dans une des baies le plus grand banc de krill échantillonné depuis 20 ans. L'étude du comportement alimentaire du krill en réponse à la baisse de la production primaire a montré l'impact du krill sur les spectres de taille des communautés mésozooplanctoniques, et en particulier sur les espèces de petites tailles. Un autre type de forçage a été mis en avant dans le golfe du Lion, où les structures physiques très variables induites par les apports du Rhône, le courant Liguro-Provençal et les vents influent directement sur la distribution spatiale du zooplancton. Des sous-régions ont été identifiées à partir de corrélations entre des paramètres physiques tels que la stratification de la colonne d'eau et des paramètres biologiques tels que la concentration en chl-a ou la pente des spectres de biomasse normalisée. / Zooplankton size structure and spatial distribution were investigated in a bay along the West Antarctic Peninsula (WAP) and in the Gulf of Lion in Western Mediterranean Sea. Zooplankton size spectra were determined with the use of two optical sensors, the Laser Optical Plankton Counter (LOPC) and the ZooScan / ZooProcess system. Using features of the biomass size spectrum is was possible to identify different forcing processes that affected zooplankton size spectrum and spatial distribution in the two ecosystems. In WAP, late fall is a transition time at all the trophic levels, with the decrease of primary production and the aggregation of Antarctic krill (Euphausia Superba) in continental bays. ADCP data permitted to find in a bay the largest Antarctic krill swarm reported in the last twenty years. Study of krill feeding behavior in response to the decrease of primary production showed impact of krill on mesozooplankton size spectrum and especially a decrease of the small size species abundance. A different type of forcing was found in the Gulf of Lion, where zooplankton spatial distribution was affected by physical structures such as the inputs by the Rhône river, the Liguro-Provençal current and winds. The correlation between physical and biological parameters e.g. water masses stratification, chl-a concentration, slope of the normalized biomass size spectrum (NBSS), allowed the identification of three different regions in the Gulf of Lion. These potential habitats show different zooplankton size structure, with strong NBSS slopes close to the coast and weaker NBSS slopes in the zone of the Rhône plume influence.

Spatial and temporal variation in lion (Panthera leo) diet within the Kalahari Gemsbok National ParkBeukes, Maya January 2016 (has links)
Thesis (MTech (Nature Conservation))--Cape Peninsula University of Technology, 2016. / A survey in 2010 suggested that the lion (Panthera leo) population of the Kalahari Gemsbok National Park (KGNP) was exhibiting a skewed sex ratio in favour of males, which can ultimately lead to a decline in lion population numbers. In the KGNP artificial water provision has influenced the abundance of resident prey and potentially, lion diet and body condition. Changes in mammalian diet, and consequently body condition, have been found to influence the sex ratio of offspring. In response to a concern that diet may be influencing lion sex ratios in the KGNP, aspects of the spatial and temporal variation in lion diet were investigated between May 2013 and June 2015. The lion diet profile in the KGNP was described using evidence of prey remains identified through GPS cluster analysis (n = 278) from seven collared lionesses, lion scat analysis (n = 189) and opportunistic observations of lion feeding events (n = 52). Spatial variation in diet was investigated between three regional landscape types (north, south and west), based on the different vegetation types represented within each area, and two habitat types (riverbeds and dunes). Seasonal variations were assessed according to the hot-wet season (November to April), and the cold-dry season (May to October). Findings were also used to assess whether lion diet in KGNP has changed over the last 45 years through evaluating results from historical lion diet studies.
