Significance We use a diverse set of lake and landscape proxy indicators to characterize initial human occupation its impacts on the Azores Archipelago. The these islands began between 700 850 CE, years earlier than suggested by documentary sources. These early occupations caused widespread ecological disturbance raise doubts about islands' presumed pristine nature during Portuguese arrival. earliest explorers arrived at end Middle Ages, when temperatures were higher average, westerly winds...
The location of the Azores Archipelago makes this group islands an excellent setting for investigating past long-term temperature and precipitation changes in central North Atlantic region. Here, we present a chironomid-based quantitative reconstruction record oxygen isotope composition chironomid head capsules last ca. 1200 years, based on Lake Prata core (São Miguel Island, Azores). Chironomids from show that trend is aligned with prevailing global trends, indicating warming during...
A multiproxy approach was applied to a sediment core retrieved from the deep crater Lake Funda, located in middle of North Atlantic Ocean on Flores Island, Azores archipelago (Portugal). The purpose this study determine how ecosystem responded natural and anthropogenic forces over last millennium. We distinguished three main phases lake evolution using reconstructions documentary sources. (A) Climate catchment processes, as well internal ones, were drivers variability before 1335 CE, when...
Abstract Aim The species–area relationship (SAR) is one of the most distinctive biogeographic patterns, but global comparisons SARs between island and mainland are lacking for microbial taxa. Here, we explore whether form SAR drivers species richness, including area, environmental heterogeneity, climate physico‐chemistry, differ islands similarly sized areas on mainland, referred to as continental area equivalents (CAEs). Location Global. Taxon Stream benthic diatoms. Methods We generated...
Abstract Aim Understanding the roles of deterministic and stochastic processes in community assembly is essential for gaining insights into biogeographical patterns biodiversity. However, way operate still not fully understood, especially oceanic islands. In this study, we examine importance shaping diatom communities islands continents, while also investigating influence climate local water chemistry variables on species distributions. Location Global. Taxon Stream benthic diatoms. Methods...
ABSTRACT Aim To evaluate the patterns of stream diatom beta diversity in islands versus continents across scales, to relate community similarities with spatial and environmental distances investigate role island characteristics shaping insular diversity. Location Africa, America, Europe Pacific. Time Period Present. Major Taxa Studied Stream diatoms. Methods We compared between at large scales (within biogeographic regions) two study regions (America Europe) small islands/equivalent areas...
Here, we present the data obtained from samples collected in a field campaign during spring of 2015 which aims for better understanding diversity and distribution patterns freshwater diatoms Madeira Island. Following European Portuguese standards recommendations routine diatom sampling analysis, 40 sites, distributed 27 permanent streams identified species present, using general floras studies diatoms. Little is known about assemblages Archipelago. This study reports survey sites Island...
The Madeira Island (Portugal; 32°24'-33°07'N, 16°16-17°16'W; 796 km2) is an oceanic island located in the North Atlantic, about 980 km south of Portugal and 700 west African coast. presence freshwater invertebrates islands has always raised questions concerning dispersal, colonisation evolution. Therefore, fauna attracted interest many researchers past, first publications going back to nineteenth century. Initial studies were mainly taxonomic, resulting a checklist macroinvertebrates with...

Freshwater diversity, and diatoms in particular, from Desertas Islands (Madeira Archipelago, Portugal) is poorly known, although the are protected became a Natural Reserve 1995. During two field expeditions 2013 2014 to Deserta Grande Island, several freshwater terrestrial habitats were sampled. The analysis of these samples aims contribute biodiversity assessment biota present Island. Here, we diatom diversity Island resulting that survey. This study contributes improve knowledge Madeira...
