Field guide of the orchids in Sierra de Mijas (Benalmadena) Spain

In comparison with other European nations, in our country there are many divulgative books dealing with flora and fauna. Nevertheless there exist numerous studies that circulate exclusively along university departments and are not very known by the citizens. Since the 1970’s, fields guides dealing with the flora of the Iberian Peninsula began to be edited and, later, guides about orchids have been published in Granada, Almería and other zones of interest. In spite of these latest editions there is still a lot to investigate.
In our study we try, as far as possible, to fill in this gap and contribute to the knowledge of the flora at the Sierra de Mijas (Benalmádena, Málaga, Spain). With this purpose we have visited weekly, during the years between 2000, 2001 and 2002, eleven routes which cover all the hillsides of the mountain. 28 species grouped in five types were found. If we compare our catalogue with the only one which exists about the flora at the Sierra de Mijas, we can say that we have increased it in 9 species (Ophrys picta, O.bilunnulata, O.lupercalis, Orchis langei, O.conica, Serapias lingua, S.strictiflora, Anacamptis pyramidalis). Afterwards we carry out a dicotomic key to identify the species, using the most evident criteria. In the same way we describe the 28 species found in a more extended way, including the best photographs and maps of distribution we have obtained in these 3 periods of searching. We need to point out the description of a hypocromatic specimen of Ophrys tenthredinifera we have proposed as a variety of “alba”.

The public lighting of Igualada. Light pollution

Objectives: The main purpose of this investigation was to establish the level of light pollution that produces the public lighting of Igualada. Detect the causes and the factors that take part in the production of light pollution and present in a logical, easy way collected data. Recommendations will be proposed if it is necessary. Both general and particular suggestions, addressed to improve the lighting system.
Theory: Light pollution: Brightness or shire of the night sky produced by diffusion of artificial light that escapes to the sky. Is what we usually call urban sky glow.
Causes of light pollution: There are three major causes, public lighting, special lightings, and lamp types.
Effects of light pollution: Light pollution directly effects consumption, but also has ecological and economic effects.
Conclusions: The actual state of the public lighting in Igualada is not acceptable. However if the improvement policies continue, and no new polluting fixtures are installed, we could get an efficient and sustainable lighting. From the analysis of the collected data we detect that a 67% of the public lights produces light pollution. A 22% are extremely polluting. In certain recently constructed areas we have noticed a massive installation of mercury vapour lamps.
Future expectations: Make people become aware of this problem is the best expectation that we could imagine. The city council has been interested in this study. In the future it would be interesting to establish a close collaboration in order to improve public lighting system.
