Article
Disruptive effects have been described on the plants and ecosystems of oceanic islands due to the introduction of invasive herbivores. In the Canary Islands the European rabbit (Oryctolagus cuniculus L.) was introduced five centuries ago and currently is widespread in all ecosystems, although in the laurel forests it is very scarce. However, on Mor...

The monitoring of ecosystems and forests is an urgent requirement in the current framework of global change. It is particularly necessary on oceanic islands where their rich biodiversity is highly vulnerable, with many narrow-ranged endemic species. Quantifying and mapping forest health through key ecological variables are essential steps for manag...

The Teide broom, Spartocytisus supranubius , is an endemism of the Canary Islands (Spain) and the dominant legume of the Tenerife high-mountain ecosystem in Teide National Park (N.P.). Biotic and abiotic stresses are causing a progressive deterioration and decline of the population of this keystone legume. Since its symbiosis with rhizobia is the m...
Article
The European rabbit (Oryctolagus cuniculus) is a key prey species in Mediterranean ecosystems. However, it is also considered a pest on many oceanic islands, even though its true abundance and ecological effects on different island habitats are poorly understood. We present data on rabbit abundance for the best-preserved habitats of the Canary Isla...

Invasive alien species and climate change are two of the main current threats to conservation of biodiversity worldwide. Their effects have been extensively studied individually, but we know less about their combined effect. This study analyzes the population changes in the plant community of the high mountain legume shrub habitat of Tenerife over...
Article
Aleppo pine (Pinus halepensis Miller) has been one of the most used Pinus species in reforestation in the Mediterranean Basin and in many other regions outside its native range. Its massive use in plantations combined with its low environmental requirements, relatively short juvenile period and adaptability to human disturbance make P. halepensis a...

Aim: Insular woodiness, referring to the evolutionary transition from herbaceousness towards woodiness on islands, has arisen at least 38 times on the Canary Islands. Distribution patterns and physiological experiments have suggested a link between insular woodiness and increased drought stress resistance in current-day species, but we do not know...
Article
Full-text available
Geographic isolation substantially contributes to species endemism on oceanic islands when speciation involves the colonisation of a new island. However, less is understood about the drivers of speciation within islands. What is lacking is a general understanding of the geographic scale of gene flow limitation within islands, and thus the spatial s...

The evergreen laurel forest is a relic of ancient subtropical/tropical forests, of which the best remnant in the Canary Islands is in Garajonay National Park, on La Gomera island. The soil microbiome associated with a mature undisturbed (unburned) laurel forest was characterized at two locations at different topographical positions on the mountain:...
Article
Los efectos de especies invasoras en islas oceánicas han sido ampliamente estudiados a escala global. Sin embargo, en Canarias tenemos aún poco conocimiento de la repercusión que han tenido en nuestros ecosistemas, y de cómo siguen influyendo en la degradación de los mismos. Esto es especialmente patente en el caso del conejo europeo, ya que es una...
Article
Global warming is changing the structure and elevational limits of treelines around the world. This could become a threat particularly on islands, where usually high mountain ecosystems occupy small areas. Tenerife, with a maximum elevation of 3715 m, is an excellent example of this. In this subtropical island, the treeline composed by endemic pine...

Background and aims: Plant survival under extreme drought events has been associated with xylem vulnerability to embolism (the disruption of water transport due to air bubbles in conduits). Despite the ecological and economic importance of herbaceous species, studies focusing on hydraulic failure in herbs remain scarce. Here, we assess the vulnera...
Chapter
After the conquest, the increasing disturbance of the island ecosystems, and their fragility, forced the authorities to implement conservation measures to protect them. Thus, since the sixteenth century, provisions were enacted and sometimes implemented to control the destruction of forests and water sources. In later centuries, reforestation was r...
Chapter
The climate of the Canary Islands can be classified, according to the latitudinal situation and the oceanic character of the islands, as maritime subtropical, and, particularly by its seasonal regime with summer drought that lasts more than two months after the summer solstice, as Mediterranean. Within this general climatic framework there are impo...

The Canarian non-vascular flora (s.l.) is estimated at 5508 species of which 163 are considered endemic. It includes algae, fungi, lichens and bryophytes, highly diverse organisms belonging to five kingdoms, Fungi, Bacteria, Protozoa, Chromista and Plantae, living in terrestrial and marine environments. They notably contribute to the biodiversity o...
Chapter
The birth of the Canary Islands coincides with the halting of the northeast-bound African Plate by its impact against Europe and Asia and with the resultant Alpine orogeny. The rotation of the African Plate and distension in the Central Atlantic ridge released an effusion of magma that built up the Canary Archipelago. The present subaerial island e...
Chapter
The Canary Islands are an Atlantic oceanic archipelago off NW Africa located between 13°20′–18°10′W and 27°37′–29°25′N. It is formed by seven main inhabited islands: from E to W these are Lanzarote, Fuerteventura, Gran Canaria, Tenerife (Fig. 1.1), La Gomera, La Palma and El Hierro. To these are added the small islets and rocky components of the so...
Chapter
The vegetation of the Canary Islands is very diverse and many of this communities are endemic. The widespread and more representative plant formations of the natural landscapes of the islands display a marked zonal distribution, with a clear distribution into altitudinal belts (Fig. 6.1). These belts are unevenly developed on the north and south sl...
Chapter
The arrival of the human being in the islands caused a gradual alteration of the plant cover. Initially, changes started slowly, because the aboriginal population was relatively scarce and lacked metal tools for massive felling. But changes in the vegetation accelerated after the Castilian conquest, which brought a major population increase, better...

Alpine ecosystems on islands are among the most isolated on Earth, leading to very high rates of endemism. Endemic species on oceanic islands are particularly vulnerable to invasive herbivores. In the alpine zone of Tenerife, which harbors a unique endemic flora, the dominance pattern of the two most dominant species in our days (Spartocytisus supr...
Article
The name Zygophyllo fontanesii-Sarcocornietum perennis is rejected as it is invalid and the new name Halimiono portulacoidis-Salicornietum perennis is proposed with two subassociations: typicum and limonietosum canariensis. The name Salicornietum perennis for Cuban communities is corrected to Salicornietum ambiguae.

Post-fire salvage logging (SL) is a common management action that involves the harvesting of burnt trees. As a consequence, a large amount of biological legacies in the form of logs and other coarse woody debris are removed from the post-fire habitat, creating a more simplified landscape. Therefore, SL could act as an additional disturbance over th...
Article
The majority of documented extinctions world-wide in the last four centuries are of species endemic to islands. However, the phenomenon of delayed extinctions as a result of habitat loss has rarely been assessed on oceanic islands. In this study, we tested whether extinction debt (ED), in general, occurs on islands and for which taxonomical groups...

The water transport pipeline in herbs is assumed to be more vulnerable to drought than in trees due to the formation of frequent embolisms (gas bubbles), which could be removed by the occurrence of root pressure, especially in grasses. Here, we studied hydraulic failure in herbaceous angiosperms by measuring the pressure inducing 50% loss of hydrau...
Article
The general dynamic model (GDM) of oceanic island biogeography integrates rates of immigration, speciation and extinction in relation to a humped trajectory of island area, species carrying capacity and topographic complexity through time, based on a simplified island ontogeny. In practice, many islands have more complex ontogenies, featuring surfa...

Data
Premise of research. One of the most conspicuous aspects of island floras is the relatively high proportion of woody species. Often, but not always, these woody species have developed wood on the islands and have evolved from herbaceous continental ancestors, a phenomenon known as insular woodiness. Shifts from herbaceousness toward increased woodi...

Forest fires modify the soil environment, often triggering severe soil degradation. In this paper, we studied the impact of a large northern Tenerife Canary pine forest wildfire on a set of relevant soil properties, focusing on their evolution in time and relationship with soil water repellency. To do this, soils were sampled at four sites (burned...
Article
Canary Islands pine (Pinus canariensis Chr. Sm. ex DC) is often described as serotinous, even though most serotinous attributes are absent or weakly developed and the trees do not seem to experience a natural fire regime that would favor and sustain serotiny. We studied the age structure of 22 old-growth stands on the slopes of Mt. Teide on Tenerif...
Article
The endemic flora of the Canary Islands is remarkable but highly vulnerable to environmental changes. Several factors, such as fire, could be threatening. The purpose of this study was to analyze various treatments in endemic threatened species which could have been growing in the understory of the Canary pine forest. We attempted to improve germin...
