"In the last few decades there has been an increase in the area of distribution of wild ungulates", explains Pelayo Acevedo, lead author of the study and researcher in the Department of Animal Biology at the University of Málaga, speaking to SINC.
The study, which has been published in Landscape Ecology, considered the changes with time of the structure of the landscape and how these variations affect the distribution in the past (the 1960s), present (1990s) and future (about 2040) of roe deer (Capreolus capreolus), Spanish ibex (Capra pyrenaica), red deer (Cervus elaphus), and wild boar (Sus scrofa), in Andalucía.
According to Acevedo, wild ungulates were more limited in the past than they are at the moment. "The environmental favourability obtained from our models for the present is more widely distributed than that from our models for the past", asserts the researcher. The current expansion of wild ungulates is also occurring in the rest of Europe, but unevenly, depending both on the species and the country.
Change in land use seems to have been decisive in the expansion of all the species studied, but "it has not been the only factor". In the case of some species, like the red deer, the expansion has been "a process accelerated by human intervention", say the authors. Nevertheless, anthropogenic activity has not affected them all equally.
"The expansion of these species in recent decades in Spain is also related to official protection measures, above all those intended to regulate hunting pressure, and, to a lesser extent, human mobility", the study points out.
A long-term expansion
The results suggest that the changes in land use of recent decades are "at least partly responsible for the current expansion of wild ungulates", affirms the researcher. If the current trend is maintained, we can expect that these species, except the Spanish ibex, will continue increasing their range of distribution in the near future in Andalucía.
According to the scientists, the areas currently deemed to be "favourable" for the distribution of these animals will remain favourable in the future. Apart from these zones, "we expect that new favourable areas for these species will appear", affirms the author.
Given that wild ungulates seem likely to continue their expansion in the 21st century, the research team proposes that we improve our knowledge of them to assure their survival, and that of their environment.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
