Advantages and disadvantages of different observation methods on a troop of wild olive baboons at a river in Southern Kenya

Every observation method has its advantages and disadvantages and a well-adopted method gives more reliable results. Factors affecting the choice of the most appropriate methods for recording Foraging behaviours include species, group size, environment, seasons and age. The focus for this study was to determine which method is most appropriate for studying the Foraging behaviour of a troop of 89 olive baboons (Papio anubis) living in a riverine forest by the Southern Ewaso Ng'iro River by Lale'enok Resource Centre in Kenya. To determine this, a literature study was carried out to compare methods from monkeys and apes. I found instantaneous sampling was the most common method with intervals of 5 minutes in most cited studies.

Dogs on the move : a study of the travel habits of Swedish dogs and their owners? awareness of infectious diseases.

ABSTRACTThe principal aim of the study was to compare the feeding behaviour of cattle, sheep and goats on pasture and explain any differences between speices. Furthermore, I compared Foraging behaviour between dry season and the beginning of the rainy season, in order to see any relationships between weather and behaviour.The study was carried out in Shompole in southern Kenya. Behavioural data were collected by observing herds of cattle, sheep and goats on pasture. The livestock were herded on pasture during the days and kept in bomas, where people live, during the nights. The weather in Shompole is characterized by high ambient temperature and low, bimodal rainfall.

En jämförelse av beteende mellan vävande hästar och två icke vävande hästar under liknande förhållanden :

Today we keep our horses in a way that is easy for us humans but may not always be the most optimal way for the horse. Often the housing of the horse prevents the horse from performing behaviours that they have natural needs to perform. It is not unusual that animals that can not adapt to their environment develop abnormal behaviours. Many of our stabled horses therefore develop some kind of stereotypic behaviour. This study was made in purpose of comparing the behaviour of a weaving horse to two non-weaving horses under similar conditions, where one of the horses was stabled next to the weaving horse and the other horse was stabled further away in the same stable. Seven weaving horses were included in the study.

Wolf movement patterns and the distribution of moose kills : implications for human harvest?

Most studies regarding wolf (Canis lupus) predation on moose (Alces alces) have focused on the total annual consumption of moose within a wolf territory but few have tried to describe the spatial impact of wolf predation on a local scale. In this study I have analyzed wolf movement data, wolf predation, moose hunting statistics and moose hunter observations to investigate how wolf predation affects the human harvest of moose in Scandinavia. Since wolves prey on mostly juvenile moose during summer, analysis of their summer movement patterns is crucial to understand its impact on the human harvest later during autumn. In this study both reproducing (n = 45) and non-reproducing wolves (n = 12) reduced their movement range during summer to 66% and 67% of their annual movement range, respectively. Reproducing wolves increased their movement range from early to late summer while non reproducing wolves did not.

Välfärd hos växande nötkreatur ? finns den?

During an investigation of animal welfare in animal production, the focus has for a long time been focused on the absence of stress, suffering and injuries, and positive emotions have not been prioritized. However, in recent years that has been drastically changed. The public interest have increased for buying animal products from animals that have had a decent life, which have led to that play, exploratory behavior and other positive behaviours has come to play a significant role in welfare assessment. The welfare of cattle is difficult to assess since there is currently no ancestors to study, it is thus difficult to determine which behaviors can be regarded as natural and thus positively related, acordingly the welfare of cattle have been forgotten and research on positive emotions of cattle have not been prioritized. The aim of this study was to observe which behavior growing cattle performe, and if there was any differences of which kind of behavior that was observed, if the cattle is keept on slatted floor or on a deep straw bedding. Furthermore, antoher purpose was to investigate if the observed behaviours indicate a positive, negative or natural welfare, and if it is possible to use the observed behaviours in a welfare assessment.

Evaluation of a behaviour protocol for use in recording the behaviour of horses following administration of methadone

There is a need for correct and adequate pain assessment in horses. Methadone is used in pain management in horses but the full pharmacokinetic picture of methadone is not yet known. The aim of this pilot study was to develop a behaviour protocol and suggest a reliable recording method for use in a larger research project with an aim to potentially correlate behaviours to concentration of methadone in blood. In this study two coldblooded trotters were given methadone intravenously with doses of 0.1 mg/kg for horse 1 and 0.2 mg/kg for horse 2. The horses were videotaped pre and post methadone administration.

Neonicotinoids and honeybee health : the effect of the neonicotinoid clothianidin, applied as a seed dressing in Brassica napus, on pathogen and parasite prevalence and quantities in free-foraging adult honeybees (Apis mellifera)

Sub-lethal doses of neonicotinoids have been shown to negatively impact the health of honeybees. However, most studies to date have exposed bees only artificially to these pesticides under laboratory conditions. There have been just a few well designed and replicated studies of the impacts of realistic neonicotinoid exposure on honeybees Foraging under field conditions. In order to close this knowledge gap, and to test the influence of the neonicotinoid clothianidin on honeybees, we used a study system of 16 paired, spatially separated (>4 km) spring oilseed rape fields in the south of Sweden. The fields were paired according to land use, the surrounding landscape and geographical proximity, using GIS.

Renen och nötkreaturet, en jämförelse mellan två olika typer av idisslare :

The aim of this literature review was to make a comparison between the feeding requirements of Swedish reindeer (Rangifer tarandus tarandus) and meat producing cattle (Bos taurus) within farming. Reindeer are an intermediate feeding type; they have the ability to adapt to short term seasonal changes in food. They avoid eating fibre as much as possible and display highly selective behaviour while Foraging. Adaptation to harsh environments with a limited amount of food has made reindeer dependent upon easily digestible food and consequently their digestive systems are less capable of processing plants with high fibre content. Herding is an extensive system which requires a significant amount of land and labour and describes the reindeer industry.

En jämförelse av hästens tidsbudget och dygnsrytm : frilevande och i stall

Today it is common to have adult horses stabled for most of the day. This limits the horses? ability to perform some of their natural behaviors such as Foraging and movement. The purpose of this review was to compare the feral horses? diurnal rhythm and time budget with stabled horses.

The distribution of Moose (Alces alces) during winter in southern Sweden : a response to food sources?

The traditional Swedish way of dealing with browsing damages made by moose, is to reduce the moose population. However, a growing way of dealing with damages made by several ungulate species, including wild boars in particular is to redistribute them with supplementary food sources. Attracting them to settle in habitats less vulnerable to damages made during Foraging. This study we tracked collared moose in southern Sweden from January throughout April in the year of 2009. From the tracking data their ?favourite? positions was selected and visited in order to study the features that attracts moose during winter.

Distribution of wild boar (Sus scrofa) damage and harvest loss in crop fields

The last decades the populations of wild boar (Sus scrofa) has increased rapidly over the species? entire European range, including Sweden. This is followed by increasing human-wildlife conflicts as a result of the wild boar Foraging behavior, causing damage to agricultural crop fields due to trampling and feeding. To be able to minimize damage we need more knowledge of where in the fields the risk of damage is high and what features in the landscape that affect this risk. I analyzed damage distribution in relation to the distance to six different landscape features; forest, road, ditch, building, game field and bait station, in the study area, the Island Mörkö in eastern central Sweden.

Hur anpassar sig Gyps-gamar (Gyps rueppellii och G. africanus) i Östafrika till oregelbunden och osäker födotillgång?

In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.

The influence of forestry stands treatments on brown bears (Ursus arctos) habitat selection in Sweden ? an option for Alberta forestry?

The brown bear population in Alberta, Canada has been decreasing, while the Swedish has been increasing and all the affecting parameters are not known. This study examined the difference in these populations to see if an explanation could be found in differences between the forest management. The aim of the paper was to see if stand treatments had an influence of brown bears habitat selection in autumn in Sweden and how the results can be used in Alberta. This was done by analyzing bear positions in Sweden with forest data, and comparing forest management data for the study area in Sweden with forest management data for Alberta. The results displayed that mature forests over 60 years that have been commercially thinned are selected by bears rather than forests over 60 years that have not been commercially thinned in.

En pilotstudie av unghästars användning av ligghall i grupphållningssystem

Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. One of the alternatives to the traditional format in individual boxes is called group housing. Group housing systems allow horses to live in herds and they can choose how they want to distribute the hours of the day between movement, resting and Foraging. The purpose of this study is to examine how frequently the young horses in a group housing system use the indoor lying area.

Stopover duration and field site selection by whooper swan (Cygnus cygnus) at Lake Tysslingen, Sweden

The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.
