Underwater noise pollution is an increasing environmental problem which might affect communication, behaviour, fitness and consequently species' survival. The most common anthropogenic noises in aquatic habitats derive from shipping. In the present study we investigated the implications of noise pollution from a ship on the sound detectability, namely of conspecific vocalizations in the Lusitan...

http://dx.doi.org/10.1016/j.anbehav.2014.10.011 0003-3472/© 2014 The Association for the Study of A Aggressive behaviours have an important impact on the social organization of animals and on the social status of individuals, especially in gregarious species. Agonistic interactions between territory holders are essential to set and reinforce territorial borders. Additionally, agonistic displays...

Fluctuating asymmetries (left-right differences in symmetric traits) can be negatively related to fitness parameters in a number of biological systems. Hence, it has been suggested that symmetric individuals should outcompete asymmetric individuals during intraspecific agonistic encounters. However, there is a lack of experimental evidence for such a relationship. We investigated the relationsh...

An agonistic display by a white shark was observed and photographed during cage dive at Guadalupe Island in November 2015. Exhibiting exaggerated pectoral fin depression, behaviors have been previously described several species. This account may be the first record of close proximity to caged diver, exhibiting strong depression significantly dipped, mid-agonistic display. Such displays should c...

Fas triggering by agonistic antibodies or by its cognate ligand, FasL, induces apoptotic cell death, whereas mutation in the Fas death domain is associated with lymphoma progression. On prolonged culture in the presence of an agonistic anti-Fas antibody, we raised a Jurkat cell line resistant to agonistic antibodies but still sensitive to soluble FasL, which carried at the heterozygous state, a...

Current legislation in the United Kingdom stipulates that horses should not be slaughtered within sight of one another. However, abattoir personnel anecdotally report that, for semi-feral unused to restraint, co-slaughtering alongside a conspecific could reduce distress through social buffering and improve safety, but there is lack evidence support this. CCTV footage from an English was assesse...

By relying on theoretical concepts which critical is based one hand, other a possibility shown their interference aim to introduce perspective within through establish new methodology two disciplines. aforementioned demonstrated in coexistence S.

In mammals, purring has been described in mostly affiliative contexts. In the ring-tailed lemur (Lemur catta), both males and females purr, but only males were observed purring in agonistic contexts. In order to determine whether male ring-tailed lemurs purr as aggressive displays during intrasexual agonistic encounters, 480 h of focal data were collected on 25 adult males from Beza Mahafaly Sp...

The aggressive components and opioid-mediated behavioral consequences of various types of intraspecific agonistic interactions between individual male mice were examined. The size of the animals, their previous social history (group or isolation housing) and territory on which the encounter took place were varied to yield 26 different 'resident-intruder' paradigms. In these agonistic encounters...
