Large-Range Movements of Neotropical Orchid Bees Observed via Radio Telemetry

Neotropical orchid bees (Euglossini) are often cited as classic examples of trapline-foragers with potentially extensive foraging ranges. If long-distance movements are habitual, rare plants in widely scattered locations may benefit from euglossine pollination services. Here we report the first successful use of micro radio telemetry to track the movement of an insect pollinator in a complex and forested environment. Our results indicate that individual male orchid bees (Exaerete frontalis) habitually use large rainforest areas (at least 42-115 ha) on a daily basis. Aerial telemetry located individuals up to 5 km away from their core areas, and bees were often stationary, for variable periods, between flights to successive localities. These data suggest a higher degree of site fidelity than what may be expected in a free living male bee, and has implications for our understanding of biological activity patterns and the evolution of forest pollinators.

Avaliação da viabilidade econômica da implantação de uma usina de triagem e compostagem na cidade de Rio Claro-SP

The question of the solid waste is without a doubt one of the biggest problems faced for the world-wide population in the present time, resulting in the call “collapse of the garbage”. In this direction that appears the composting, in the scope of the treatment of organic waste origin, that in Brazil, approximately correspond 50% of the generated volume. However, the rare plants of selection and composting (UTC) existing at least do not obtain auto-to support themselves, increasing to each day the number of deactivations, almost always related the financial questions. In this direction, the present research brings the analysis of the economic viability of the implantation of a UTC for the city of Rio Claro-SP, relating it with the thick organic composition sales, for the cultures of vegetables cultivated in a ray of 30 km of the study area. For in such a way, they had been carried through, calculations concerning the regional demand for organic composition, and the verification of the implantation costs and operation of the plant. The reached results had been the flow of box for the first year of functioning of the UTC, as well as the break-even point between the gotten expenditures and prescriptions. From this relation investment profitability, it was verified that the UTC is presented impracticable under the economic point of view.

Is it appropriate protective figure "Plant Micro-Reserves" to protect tree species? The example of Betula pendula subsp. fontqueri in "La Garganta de los Caballeros" (Ávila)

The figure of protection "micro-reserves" was created in the Region of Valencia (ANONYMOUS, 1994) with the aim of protecting endangered plant species. This is one of the areas of greatest floristic richness and uniqueness of the western Mediterranean. In this area rare, endemic or threatened vascular flora has a peculiar distribution: they appear to form small fragments spread over the entire region (LAGUNA, 1994; LAGUNA, 2001) The protection of every these small populations of great scientific value has significant challenges. It doesn´t try to protect every species that set out in Annex IV of the by then existing Law 4 / 1989 (repealed in 2007), or to protect to the most ecological level with the creation of Natural Protected Area but an intermediate level: the plant community of small size. According to the decree: “as Micro-Reserve will be declared the natural parcels of land under 20 hectares that contain a high concentration of rare plants, endemic, threatened or of high scientific interest” (ANONYMOUS, 1994) . Of course, the statement of an area as micro-reserve carries certain prohibitions that are harmful to the vegetal community
