Modellen baseras pa biologiska studier av sarskilda rovdjur och deras bytesdjur, mer speci kt, lejon och zebror. Baserat pa dessa fakta skapas generella regler for att kunna beskriva beteenden vid jakt och ykt, med fokus pa det forstnamnda.

Pełny tekst źródłaThe foraging of breeding Jackass Penguins Spheniscus demersus was studied in and around southwestern Cape Province, Saldanha Bay (33⁰ S, 18⁰ E), South Africa. Penguins are difficult to observe at sea. Hence, I devised a number of new techniques for studying the foraging behaviour of Jackass Penguins at sea. I built electronic and autoradiographic remote-sensing devices to measure swimming speed, distance travelled and time spent at each depth by foraging Jackass Penguins. Penguin swimming speed was reduced in proportion to the cross-sectional area of the devices, and results derived from birds wearing the devices had to be interpreted accordingly. Penguins do not regurgitate their stomach contents when handled, so I constructed a wet-offloading stomach pump which extracted 100% of the stomach contents. Using this pump, I determined that the rate of digestion of fish and squid by Jackass Penguins differed. Care is needed in diet interpretations where both fish and squid are major food items.

Los carábidos, C. fuscipes, P. rufipes, P. cupreus y Metallina sp. y el anthocorido O. majusculus presentan movimiento bidireccional entre cultivos adyacentes de alfalfa y maíz durante la estación. En contraste, C. septempunctata sólo se movió desde la alfalfa hacia al maíz. Los individuos de O. majusculus y C. septempunctata que colonizaron el maíz en el estadio vegetativo provinieron de la alfalfa, indicando que la alfalfa actúo como fuente de estos depredadores. Sin embargo, en el período reproductivo, el maíz actuó como una fuente de C. fuscipes, P. rufipes, P. cupreus, Metallina sp. y O. majusculus hacia la alfalfa, principalmente después de corte. El movimiento de carábidos, estafilínidos y arañas fué más intenso desde los cereales de invierno hacia los hábitats seminaturales que desde los prados hacia a los hábitats semi-naturales, indicando que el hábitat adyacente moldea el movimiento de los depredadores hacia los hábitats seminaturales adyacentes.
The abundance and dispersal activity of O. majusculus were not different in maize plots with moderately high or low weed density. The carabids C. fuscipes, P. rufipes, P. cupreus and Metallina sp. and the anthocorid O. majusculus presented bidirectional movements between adjacent alfalfa and maize crops during the season. In contrast, C. septempunctata only moved from alfalfa to maize. The plant-dwelling O. majusculus and C. septempunctata that colonized maize at early vegetative stages came from alfalfa, indicating that alfalfa acted as a source of predators towards maize. However, in the reproductive growth stage period, maize acted as a source for C. fuscipes, P. rufipes, P. cupreus, Metallina sp. and O. majusculus moving to alfalfa, mainly after cuttings. After an alfalfa cutting, margins also acted as a refuge for carabids. Spillover of carabids, rove beetles and spiders was stronger from winter cereals to semi-natural habitats than from meadows to semi-natural habitats, indicating that neighbourhood identity shapes spillover effects to adjacent semi-natural habitats.

Pełny tekst źródłaIncludes bibliographical references.
The interactions between populations can be positive, neutral or negative. Predation and parasitism are both relationships where one species benefits from the interaction at the expense of the other. Predators kill their prey instantly and use it only for food, whereas parasites use their hosts both as their habitat and their food. I am particularly interested in microbial parasites (including bacteria, fungi, viri, and some protozoans) since they cause many infectious diseases. This thesis considers two different points in the population-interaction spectrum and focuses on modeling host-pathogen and predator-prey interactions. The first part focuses on epidemiology, i. e., the dynamics of infectious diseases, and the estimation of parameters using the epidemiological data from two different diseases, phocine distemper virus that affects harbor seals in Europe, and the outbreak of HIV/AIDS in Cuba. The second part analyzes the stability of the predator-prey populations that are spatially organized into discrete units or patches. Patches are connected by dispersing individuals that may, or may not differ in the duration of their trip. This travel time is incorporated via a dispersal delay in the interpatch migration term, and has a stabilizing effect on predator-prey dynamics.
