Article
Full-text available
Research in Macaronesia has led to substantial advances in ecology, evolution and conservation biology. We review the scientific developments achieved in this region, and outline promising research avenues enhancing conservation. Some of these discoveries indicate that the Macaronesian flora and fauna is composed of rather young lineages, not Terti...
Article
Full-text available
The Azorean islands have been historically affected by human activities, mainly due to the combined effects of habitat degradation and fragmentation, and the introduction of exotic species. We here aim to analyze the role of environmental characteristics and spatial descriptors in supporting regional biodiversity of macroinvertebrates by considerin...
Article
Full-text available
In Mediterranean temporary ponds, the timing of annual flooding is highly variable and depends on heavy seasonal rains. Ponds can flood in the autumn, winter, or spring, and thus the environmental conditions faced by emerging zooplankton can be very different. We performed an experiment in a climatic chamber where we simulated annual variation in n...
Article
Organisms are exposed to multiple environmental factors simultaneously to which they often respond behaviorally, morphologically and/or physiologically. Amphibian larvae are quite plastic and efficiently adjust their phenotype and physiology to the reigning local conditions. Here we tested whether the combination of predator presence and low water...
Article
Full-text available
Historical gaps and biases in the literature may have influenced the current knowledge of the impacts of invaders on global biodiversity. We performed a systematic review and compiled the main gaps and biases in the literature and the reported negative, neutral and positive effects of exotic species on local invertebrates worldwide. We analysed the...

Islands harbour evolutionary and ecologically unique biota, which are currently disproportionately threatened by a multitude of anthropogenic factors, including habitat loss, invasive species and climate change. Native forests on oceanic islands are important refugia for endemic species, many of which are rare and highly threatened. Long-term monit...
Article
In comparison with other Macaronesian archipelagos, Azorean freshwater macroinvertebrates are characterized by a smaller list of species at the archipelago regional scale. Although knowledge of the freshwater fauna of the Azores has improved in recent years through the implementation of the "Water Framework Directive", we are still far from having...

Full-text available
The Doñana temporary pond network is characterized by a high flora and fauna species richness, including a high number of are and threatened species. This high biodiversity is due to the high abundance of ponds of different size across a broad hydroperiod range. The different geomorphological areas within the park contribute to increase the heterog...

Full-text available
Understanding the processes that lead to successful invasions is essential for the management of exotic species. We aimed to assess the comparative relevance of habitat (both at local and at regional scale) and plant features on the species richness of local canopy spiders of both indigenous and exotic species. In an oceanic island, Azores archipel...

The presence of the large branchiopod fauna in the Iberian Peninsula and Balearic Islands was recorded obtained from bibliographical and recent captures. The fauna includes 16 anostracans, 7 notostracans and 4 spinicaudatans, although we considered the different species of genus Triops as one taxa, due to the difficulties to allocate the bibliograp...
Article
Full-text available
Temporary ponds are unpredictable habitats that exhibit inundation periods of variable duration (hydroperiods). We hypothesised that changes in microcrustacean assemblages, namely among ponds (spatial variation) and within ponds at a monthly scale (intra-annual variation), would differ according to hydroperiod length. We found that the microcrustac...

Full-text available
To fully understand odonate life cycles, it is vital to analyse the patterns of larval growth, which are tightly associated with variations in environmental factors. However, the identification of larval instars is often difficult, especially for early development stages. We hypothesise that pond hydroperiod influences odonate larval growth, and te...

The province of Cadiz (South of Spain) hosts the only known locality in the world of Linderiella baetica Alonso & García-de-Lomas 2009 (Anostraca). In this paper, the geographical distribution of the species based on published sampling data focused on large branchiopods and temporary pools in Andalusia and the entire Iberian Peninsula is assessed....
Article
The EU Water Framework Directive (WFD) prioritises the importance of freshwater conservation areas in the Macaronesian Islands (Azores, Madeira, Canarias and Cape Verde). However, few studies have investigated these freshwater areas. Therefore, research must focus on establishing reference sites for aquatic conservation. We analyse the potential ef...

Full-text available
The presence of the exotic weevil Stenopelmus rufinasus (Coleoptera: Curculionidae) is closely related to the occurrence of the exotic red water fern, Azolla filiculoides. In this paper, we present the first records of S. rufinasus in Doñana National Park (SW Spain), based on sampling of macroinvertebrates in 91 temporary ponds, including monthly s...
Article
Full-text available
Human-caused disturbances can lead to the extinction of indigenous (endemic and native) species, while facilitating and increasing the colonisation of exotic species; this increase can, in turn, promote the similarity of species compositions between sites if human-disturbed sites are consistently invaded by a regionally species-poor pool of exotic...
Article
Full-text available
Geomorphological and hydrological features can provide a sound basis for global wetland classification. Temporary ponds located on the sandy area of Doñana can be classified into five different geomorphological areas. We hypothesised that these ponds would differ in soil characteristics, which may also explain differences in the composition of thei...

Invasive crayfish have severely impacted invaded aquatic ecosystems worldwide. We studied temporal and spatial variation in the range expansion of the red swamp crayfish at one of the first European localities to which it was introduced: Doñana National Park (SW Spain). In contrast to the rapid range expansion witnessed in other areas, this invasiv...
Article
1. Macroinvertebrate assemblages of temporary ponds are ideal model systems to explore biodiversity patterns and metacommunity ecology. In addition, the study of the environmental variables driving such biodiversity patterns is essential in establishing proper guidelines for the conservation of the singular fauna of temporary ponds, especially sinc...
Article
AimsHuman landscape disturbance can drive the degradation of natural environments, thereby contributing to indigenous (endemic and native non-endemic) species extinctions, facilitating the establishment of exotic species and ultimately resulting in more similar species compositions over time and space. We assessed whether similarities in epigean ar...
Article
Full-text available
Seasonal variation in macroinvertebrate assemblages usually is attributed to environmental variability, but this relationship is unclear in temporary ponds because they are highly dynamic across time. We assessed the influence of environmental variables and biotic interactions on macroinvertebrate community structure in 22 temporary ponds sampled m...

Nowadays, established populations of exotic turtles, Trachemys scripta elegans, coexist with native turtles in the wild in southern Spain. We analysed the diet of this exotic species and compared it with the diet of the two native species (Mauremys leprosa and Emys orbicularis) in two ponds. The exotic turtle is an opportunistic omnivore. In one of...

The goal of this project is to be a catalyst for more effective long-term conservation of temporary pond biodiversity and ecosystem services. We will do this by synthetizing available data on temporary pond biodiversity patterns and by experimentally resolving critical knowledge gaps that currently prevent more effective conservation and restoration. We will produce clear guidelines for temporary pond conservation, creation, and restoration, propose a regional conservation framework and organize a range of outreach activities. In the long run this project aims to improve protection, reduce degradation, improve creation and restoration projects and improve the overall reputation of temporary ponds.
