Características reproductoras de una población introducida de Podarcis pityusensiss


Resumen: Se analizo el ciclo reproductor de una poblacion de lagartija de las Pitiusas (Podarcis pityusensis),
introducida en un area urbana de la ciudad de Barcelona. La madurez sexual se alcanzo generalmente en el
segundo año de vida apareciendo subadultos en primavera. El periodo reproductor abarco desde abril hasta
agosto, siendo una de las fenologias mas tardias entre los lacertidos ibericos. Se observaron fuertes diferencias
intersexuales en el ciclo de las reservas grasas. La estrategia teproductora resulto ser mas K-seleccionada que
en otros representantes del genero Podarcis, con un tamano de puesta bajo y el tamafio de los huevos alto.
Finalmente, se evaluan las caracteristicas reproductoras de esta poblacion en funcion de sus condicionamientos
ambientales y su historia evolutiva.
Palabras clave: reproduccion, Lacertidae, Podarcis pityusensis, poblacion introducida.

Lizards as pollinators and seed dispersers: an island phenomenon

Although it is well established that many insects, birds and mammals serve as important pollinators and seed dispersers of flowering plants, the role of lizards in these processes has traditionally been considered as rare and less important. However, recent work shows both that their role as mutualistic agents has been underestimated and also reveals a striking pattern – that pollination and seed dispersal by lizards is most common on islands. We argue that this island phenomenon occurs because island lizards reach very high densities (density compensation) and experience a lower predation risk than do those on the mainland and, consequently, can expand their diet to include nectar, pollen and fruit. Although further empirical evidence is needed to confirm this explanation, such relationships could be ideal systems with which to study fundamental ecological problems, such as niche shifts, ecological release and competition.

Implications of Extreme Life Span in Clonal Organisms: Millenary Clones in Meadows of the Threatened Seagrass Posidonia oceanica

The maximum size and age that clonal organisms can reach remains poorly known, although we do know that the largest natural clones can extend over hundreds or thousands of metres and potentially live for centuries. We made a review of findings to date, which reveal that the maximum clone age and size estimates reported in the literature are typically limited by the scale of sampling, and may grossly underestimate the maximum age and size of clonal organisms. A case study presented here shows the occurrence of clones of slow-growing marine angiosperm  Posidonia oceanica  at spatial scales ranging from metres to hundreds of kilometres, using microsatellites on 1544 sampling units from a total of 40 locations across the Mediterranean Sea. This analysis revealed the presence, with a prevalence of 3.5 to 8.9%, of very large clones spreading over one to several (up to 15) kilometres at the different locations. Using estimates from field studies and models of the clonal growth of...

An analysis of habitat distribution and associations in theOdonata of theBalearic Islands, Spain

 Spatial structure of the odon. community is analysed. The different abundance of the spp. and their most characteristic habitats in the islands are indicated. The reproduction of 19 spp. on the Balearic Islands is confirmed. Coenagrion scitulum is recorded for the first time from the archipelago. The associations of spp. existing on each of the islands were established by meansof factoranalysis (correspondence analysis); a total of9 associations are defined. This study has been made on larvae exclusively. Sympetrum striolatum is the most abundant sp. in the Balearic Islands. Previous records are discussed.
