Samples of four different species of seaweed were collected monthly between October 2000 and March 2001 from the coast of the Strait of Magellan, Chile to establish baseline levels of trace metals (silver, total mercury, nickel, lead, antimony, vanadium and zinc) and to compare the accumulation capacity among species. The algae included in the study were Adenocystis utricularis (n=15); Enteromorpha sp. (n=11), Mazzaella laminarioides (n=12) and Porphyra columbina (n=6). The concentration range of each metal in microg g(-1) dry weight varied as follows: Ag=ND-0.3, Hg=ND-0.02, Ni=ND-12.6, Pb = ND-11.2, Sb=ND-1.97, V=ND-11.34 and Zn=14.10-79. Results showed that levels of Ag, Hg, Ni, Pb, Sb, V and Zn for all species were similar to those found in other studies for non-contaminated areas with very little influence from anthropogenic activity. Also among the four species studied macroalgae Enteromorpha sp. had the highest capacity for metal accumulation and could therefore be considered as a biomonitor for future studies in the area.

Summary. -The distributional status of 9 species of bats in the Iberian Peninsula are reviewed and completed. Up to now these species were poorly known due to inadequate surveys or their true rarity. These species are: Myotis bechsteini, M. emarginatus, M. mystacinus, Nyctalus lasiopterus, N. leisleri, N. noctula, Pipistrellus nathusii, P. (Hypsugo) savii and Barbastella barbastellus. (Palmeirim 1990). However, the information available on an elevated number of species, above all non cave-dwellers, is scarce. This paper offers results obtained during the last few years on the chorology of Iberian bat species which are poorly known. A compilation of bibliographic information is provided including references given by publications which are difficult to find. MATERIAL AND METHODSThe new information presented here comes from two main sources: first, a review of collections with specimens of Spanish bats not previously cited (Estacion Biologica de Donana, Sevilla, EBD; Departamento de Zoologia, Facultad Mammalia, t. 56, n° 3, 1992.
