The grey wolf (Canis lupus) is one of the most challenging species to conserve in our modern and crowded world. Due to various factors, most European wolf populations are currently growing. In Hungary, numbers have increased since the 2000s. Although spontaneous recolonisation from Slovakia is considered to be the most likely mechanism by the major...

Sleep research greatly benefits from comparative studies to understand the underlying physiological and environmental factors affecting the different features of sleep, also informing us about the possible evolutionary changes shaping them. Recently, the domestic dog became an exceedingly valuable model species in sleep studies, as the use of non-i...

When facing an unsolvable problem, dogs exhibit spontaneous human-oriented behaviours (e.g. looking at the human partner, gaze alternations between the human and the target) sooner and for longer than domestic cats and hand-raised wolves. These behaviours have been interpreted as interspecific communicative acts aimed to initiate interaction. Here,...

In the food supply chain, quality control has a very important role in maintaining customer confidence. In the EU, food safety aspects are strictly regulated; however, composition requirements and standard control methods are generally undefined. The rapidly increasing wild boar population has a growing market share in venison or game meat producti...

Dogs’ attachment towards humans might be the core of their social skillset, yet the origins of their ability to build such a bond are still unclear. Here we show that adult, hand-reared wolves, similarly to dogs, form individualized relationship with their handler. During separation from their handler, wolves, much like family dogs, showed signs of...

Automated monitoring of the movements and behaviour of animals is a valuable research tool. Recently, machine learning tools were applied to many species to classify units of behaviour. For the monitoring of wild species, collecting enough data for training models might be problematic, thus we examine how machine learning models trained on one spec...

Previous research proves dogs’ outstanding success in socio-communicative interactions with humans; however, little is known about other domestic species’ interspecific skills when kept as companion animals. Our aim was to assess highly socialized young miniature pigs’ spontaneous reactions in interactions with humans in direct comparison with that...

The animal welfare is maybe the main factor in livestock breeding, including keeping wild animals. In order not have any problems (health, economic), animals behaviour analyses with cameras can be an appropriate and relatively cheap solution. The present study aims to show the difference between the camera traps and hand-held cameras: which can be...

In Hungary there are two species of Felines, the wildcat (Felis silvestris) and the Eurasian lynx (Lynx lynx). These two species are threatened by the habitat loss and fragmentation. In addition, in the case of the wildcat there is another factor that affects the population, the hybridisation with feral domestic cats; which may lead to mixed popula...

Many dog breeds are bred specifically for increased performance in scent-based tasks. Whether dogs bred for this purpose have higher olfactory capacities than other dogs, or even wolves with whom they share a common ancestor, has not yet been studied. Indeed, there is no standard test for assessing canine olfactory ability. This study aimed to crea...

A vaddisznó a vadgazdálkodás számára jelentős bevételt jelent, szabadterületen állománya folyamatosan nő; a vaddisznós kerti vadászat iránti igényeket mégis egyre nehezebb teljesíteni, habár a kertben lévő állományok nagy része befogásból származik. Ahhoz, hogy a pár napos vadászat során a kertet üzemeltetők biztosítani tudják a vendégek által „elv...

Game damage to agriculture represents one of the most important and most frequent human- wildlife conflicts worldwide. In Europe (including Hungary) damage caused by wild boar (Sus scrofa) and red deer (Cervus elaphus) is the most significant. The volume of damage is correlated with the population density of the game species, however, not exclusive...

The aim of the present study was to examine the effect of area reduction on the hierarchy-depen behaviors of wild boars and crossbred sows (wild boar × Vietnamese pot-bellied pig) living in captivity regard to a food competition situation. We first defined the hierarchy system among 7 individuals, together for more than a year, with a mathematical...

At the end of the nineteenth century, the wolf Canis lupus was extinct in Hungary and in recent decades has returned to the northern highland area of the country. The diet of wolves living in groups in Aggteleki National Park was investigated using scat analysis (n = 81 scats) and prey remains (n = 31 carcasses). Throughout the year wolves (average...

sszefoglaló: A vaddisznó negatív hatását különböző veszélyeztetett növény-és állatfajok populációira számos vizsgálat igazolta, ugyanakkor egyes kutatások jelzik lehetséges po-zitív ökológiai szerepét is. A DALERD Zrt kőrösladányi vaddisznóskertjében 2007-2010. között vizsgáltuk két védett növényfaj állományának alakulását. Random módon elhelyezett...
