Abstract:

Dogs engage in various interactions with artificial agents (UMOs) but it is not clear whether they recognize UMOs as social agents. Jealous behaviour emerges when an important relationship is threatened by another individual, but only when the intruder is a social agent. We investigated whether UMOs elicit jealous behaviour in dogs. We tested three groups of 15 dogs, each group observed different behaviour of the UMO: mechanistic movement, non-social or social behaviour. Then, the owner interacted with another dog, the UMO and a magazine while ignoring the subject. Dogs displayed more rival-or

Abstract:

Observations of habitats are reported. A series of underwater experiments were conducted in natural habitats to answer questions concerning a) why Lamprologus ocellatus and Lamprologus ornatipinnis bury gastropod shells refuges into the substrate, and b) to examine interspecies differences in shell-using behaviours. Some behaviour patterns were analysed using phylogenetic methods. Lamprologus ocellatus and L. ornatipinnis responded to new shells in a variety of ways, shells were moved, buried (and used) or hidden (buried and not used). How shells are utilised seems to be dependant on a complex

Abstract:

While the significance of vibrational communication across insect taxa has been fairly well studied, the substrate-borne vibrations of honeybees remains largely unexplored. Within this thesis I have monitored honeybees with a new method, that of logging their short pulsed vibrations on the long term, and I have started the longstanding endeavour of underpinning the applications of it. The use of advanced spectral analysis and machine learning techniques as part of this new method has revealed exciting statistics that challenges previous expert's interpretations.

Abstract:

Human beings of all cultures build some form of shelter, and the global distribution of Homo sapiens depends on this basic trait. All great apes (chimpanzee, bonobo, gorilla, and orangutan) build analogous structures (called nests or beds) at least once a day throughout their adult lives, which suggests that this elementary technology was present before the hominid lines separated. This thesis investigates the variability and function of specifically wild chimpanzee shelters. I compared characteristics of chimpanzee nests, nesting trees, nest shape, and architecture in two savanna-dwelling pop

Abstract:

Objects that are animate occupy a special place in the human conception of the world. We ourselves are objects that are animate. So are the non-human animals which have been food, predators, cohabitants, and later companions to us during our evolutionary history. The difference between what is animate and what is not and the question of what happens when an animate object begins or ceases to operate - in essence what gives us and the other animals life - have captivated human minds for perhaps that whole time. The same goes for the apparent differences between us and those other animals. These

Ethology (the comparative study of behaviour) was officially sanctioned when the zoologists Konrad Lorenz, Nikolaas Tinbergen and Karl von Frisch were awarded the Nobel Prize in 1973. Historians of ethology then mostly embraced Lorenz's definition of the field and did not question the strategy he resorted to when he championed his ethology against other traditions in the study of animal behaviour. Among them, the French studies loomed large, and one main aim of this dissertation has been to make up for their neglect within the historiography of science.

Recently, several orb-weaving spider species have been shown to exhibit a variety of abnormal rhythms, suggesting that circadian clock-controlled rhythms may play

Circadian rhythms are endogenous molecular clocks that correspond to the 24-hour day and are regulated by light stimulus, allowing organisms to entrain to the dawn-dusk cycle. These clocks may allow organisms to anticipate daily events, influencing their behavior. In arthropods, including spiders, circadian rhythmicity is tested using activity monitors, which house individuals in tubes. However, this does not reflect the natural habitat of many spiders.

Abstract:

Marine mammals are in a precarious conservation position because of anthropogenic impacts and historic perceptions that they are a consumable commodity. In light of changing abiotic conditions, further evaluation is needed on the habitat use, behavior, and interactions among marine mammals. Conservation legislation has helped protect species, but the greatest ground swelling may be the advent of the commercial whale watching industry. The feeding grounds in Alaskan waters have made this area a prime tourism location, and these nutrient-rich waters have resulted in a confluence of marine mammal

Aspectos do repertório comportamental e de estruturas resultantes de comportamento foram levantados para aranhas da infraordem Mygalomorphae. Os principais objetivos são buscar subsídios em informações provindas de caracteres comportamentais para auxiliar a elucidação da história evolutiva do grupo e entender como estes evoluíram dentro do grupo. Foi realizado um levantamento de informações sobre refúgios nas migalomorfas, a partir das quais foram delimitados 8 caracteres. Os caracteres foram incorporados a uma matriz de dados morfológicos provinda do trabalho de Goloboff e foi realizada uma a

Abstract:

Anolis carolinensis has been a model organism for ecology and evolutionary biology since the seventies, yet there are still understudied aspects of their ecology. A five-year study has provided microsatellite genotypes to be used in building a pedigree and assess relatedness, enabling us to evaluate the spatial distribution of an urban population of A. carolinensis. Results indicate no correlation between a male’s size and the distance others keep from it; however, males belonging in the heavyweight morph are dictating the spatial distribution in this population. In addition, juvenile dispers

Este facto põe em causa, com frequência, a satisfação das suas necessidades. No caso dos felinos esta situação pode conduzir ao aparecimento, principalmente, das estereotipias locomotoras ou pacing e/ou ao excesso de inactividade, com consequente diminuição da diversidade comportamental.

Abstract:

Parasites often have profound effects on the survival and evolution of their hosts, and hence on the structure and health of entire ecosystems. Yet basic questions, such as the degree of virulence of a given parasite on its host, and factors influencing which hosts in a population are at the greatest risk of infection, are vexingly difficult to resolve. The western blacklegged tick-western fence lizard (Ixodes pacificus-Sceloporus occidentalis) system is important, primarily because I. pacificus, a vector of the Lyme disease spirochete Borrelia burgdorferi, is dependent on S. occidentalis for

Abstract:

Eshkol-Wachmann Movement Notation was applied to describe and quantify nonverbal behavioral synchrony between romantic partners. The interaction of 30 couples was observed across three study conditions, Pre-Stressor, and two Post-Stressor conditions when the female partner had been targeted with a stress manipulation. Participant-level behavior, and forms of dyadic synchrony were predicted with the male and females' self-reported attachment style. Results support theories from the attachment literature.

Abstract:

Due to the expansion of the human population we are an increasing threat to all wild animals. They are driven to exist in smaller areas and in the worst case scenario extinction. Zoos are being encouraged to improve the animal’s physical and social surroundings. Environmental enrichment is a term used for such improvements. In this behavioural study, the enrichment introduced to two Pallas cats (Felis manul) at Parken Zoo in Eskilstuna, Sweden, consisted of a fishing rod and a clothes peg with a dead mouse or chick attached. The intention was to see if the feeding enrichment could increase act

Abstract:

The curiosity whether or not animals have the characteristics of long term planning skills is fairly new. Some researchers agree that certain species have a form of episodic-like memory, in the terms of where, when and what. But the most difficult thing is to find out if these species have an aim for the future which involves what some call mental time travel. This study is a part of the discussion if the tests in long term planning and foresight can be explained by associative learning and the ability of self control in highly trained animals. Many self control and delay tasks have been condu

Abstract:

Alloparenting has played a pivotal role in every society throughout human history in ensuring the survival and healthy development of children. A large amount of theory (e.g. kin-selection) and evidence exists to support this claim, and though alloparenting is certainly not unique to humans, it is difficult to suggest that any other species benefits from it more, and certainly not one as ubiquitous as Homo sapiens. However, there is a surprising dearth of empirical research examining the causes of individual variation in the amount and type of alloparental behavior that a child receives, and w
