4 years postdoc position Ecological theory and stress ecology (Univ. Koblenz)

10 Janvier 2017,

Publié par Bioécologie

“The Working Group Quantitative Landscape Ecology investigates the effects of anthropogenic stressors (for example, toxicants, climate change) on river ecosystems, particularly invertebrates, microorganisms and ecosystem processes. We expect from you a high motivation and active contribution to research, acquisition of external funding, supervision of Phd students and teaching of modelling (6 SWS). The establishment of an independent research program linking current ecological and macroecological theories with (multiple) stressors, preferably with connections to the working group, is strongly supported. Fostering your academic qualification is part of the professional duties and you will typically acquire the necessary qualifications for a Habilitation through the intended teaching and research activities. As a member of the working group Quantitative Landscape Ecology and in close collaboration with other research groups of the institute, the successful candidate will have access to modern equipment and work in a young and interdisciplinary team of researchers.”

Applications should include a letter of motivation, a complete curriculum vitae including an overview of software skills, certificates and a letter of recommendation for the announced position from a referee. Please send your application, quoting the reference number 06/2017 before 10.02.2017 to bewerbung@uni-koblenz-landau.de

Interspecies sexual behaviour between a male Japanese macaque and female sika deer

Pelé, M., Bonnefoy, A., Masaki, S., Sueur, C. et al. (2016). Interspecies sexual behaviour between a male Japanese macaque and female Sika deer, Primates

Sexual mount of a Japanese macaque male on two different deer. a–c Sequence of a sexual mount on a first deer that accepted being ridden. d The macaque tried to mount a second deer, but the latter clearly did not accept the mountAbstract

Interspecies sexual behaviour or ‘reproductive interference’ has been reported across a wide range of animal taxa. However, most of these occurrences were observed in phylogenetically close species and were mainly discussed in terms of their effect on fitness, hybridization and species survival. The few cases of heterospecific mating in distant species occurred between animals that were bred and maintained in captivity. Only one scientific study has reported this phenomenon, describing sexual harassment of king penguins by an Antarctic fur seal. This is the first article to report mating behaviour between a male Japanese macaque (Macaca fuscata yakui) and female sika deer (Cervus nippon yakushimae) on Yakushima Island, Japan. Although Japanese macaques are known to ride deer, this individual showed clearly sexual behaviour towards several female deer, some of which tried to escape whilst others accepted the mount. This male seems to belong to a group of peripheral males. Although this phenomenon may be explained as copulation learning, this is highly unlikely. The most realistic hypothesis would be that of mate deprivation, which states that males with limited access to females are more likely to display this behaviour. Whatever the cause for this event may be, the observation of highly unusual animal behaviour may be a key to understanding the evolution of heterospecific mating behaviour in the animal kingdom.
