Abstract

Rabbits are invasive to the Canary Islands, where they were introduced 500 years ago, during the conquest, from mainland Spain. Nowadays, they occupy all islands, almost all islets, and all the habitats of the archipelago. Rabbit negative impacts are manifested at different ecological levels, from affecting species population, to disrupt native networks of interactions, or to even cause the complete alteration of the structure of the ecosystem. Current ongoing researches in various ecosystems are very concluding: we are far from knowing how would be the natural looking of the ecosystems of the islands, and today we only see what is left after 500 years of herbivorous pressure. It is urgent to raise awareness of this serious problem to subsequently implement appropriate conservation measures to control and minimize the effects that rabbits are provoking to the incomparable and unique ecosystems of the Canary Islands.

Flora canaria
Abstract

La pobreza florística del pinar canario es el objeto de estudio de esta tesis, que pretende analizar los distintos factores de alteración que afectan a la Caldera de Taburiente. A la luz de este trabajo, cabe plantearse cómo era el pinar canario antes de la llegada del ser humano, principal responsable de su degradación.

13. A comparison of bryophyte diversity in the Macaronesian Islands: island versus habitat approach

Abstract

In this paper, we present a comparison of richness patterns and floristic similarity for bryophytes in the five most important altitudinal habitat types in the Macaronesian islands. We evaluate the importance of different factors discussed in the literature in predicting species diversity applying the traditional island approach and within the framework of the new habitat approach, including area, isolation, climatic factors, geological age and human influence. From the analysis of patterns of bryophyte species distribution for selected habitats across islands and archipelagos, we specifically test the hypothesis that (i) floristic similarity is primarily determined by climatic factors, but not by geographical distance due to high dispersal ability in this species group and (ii) bryophyte richness is best predicted by area, but not by geological age of the habitat due to very low endemicity or speciation rate and high colonization rate.
