Coastal upwelling is one of the best studied oceanographic phenomena because of its effects on primary production. The western coast of the Iberian Peninsula has high biological diversity, mainly due to this primary production. In this study, the response of salinity and temperature to the occurrence of upwelling was analysed at the Ria de Vigo– and Ria de Aveiro–ocean boundary over the course of a year. Both systems were influenced by similar external forcing, but the response of thermohaline properties differed. Salinity and temperature were dependent on external forcing throughout the water column at Ria de Aveiro, whereas near-bed measurements revealed the presence of upwelled water at Ria de Vigo. Eastern North Atlantic Central Water was observed during spring–summer (summer) at the southern (northern) mouth of Ria de Vigo, but it was not observed at Ria de Aveiro. This difference may be due to the shallowness and narrowness of the Ria de Aveiro mouth, which can limit the entrance of ocean water. The trends found are unlikely to be unique, suggesting that geomorphologic characteristics of system–ocean boundaries determine how physical processes occurring in adjacent coastal areas impact estuarine properties.

Abstract The aim of this study is to compare climatic conditions between the interior of the Iberian Peninsula and the southeastern coast of Spain. The article analyzes selected elements of climate over the last 15 years (2000-2014). Synoptic data from airport meteorological stations in Madrid Barajas and Alicante Elche were used. Attention was focused on annual air temperature, relative humidity and precipitation. The mean climatic conditions over the period 2000-2014 were compared with those over the 1961-1990 period which is recommended by WMO as climate normal and with data for the 1971-2000 coming from ‘Climate Atlas’ of Spanish meteorologists group AEMET. Two of climate elements discussed were characterized by significant changes. The annual air temperature was higher by about 0.2°C in Alicante and 0.9°C in Madrid in the period 2000-2014 compared to the 1961-1990. The current winters were colder than in years 1961-1990 at both stations. Gradual decrease in annual precipitation totals was observed at both stations. In 1961-1990 the annual average precipitation in Madrid amounted to 414 mm, while in Alicante it was 356 mm. However, in the recent years of 2000-2014 these totals were lower compared to 1961-1990 reaching 364.1 mm in the central part of Spain and 245.7 mm on the south-western coast.

Abstract—Two new diploid species, Aira minoricensis and Aira hercynica, are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.

Español.  Se dan a conocer nuevas localizaciones y datos corológicos para 98 especies (61 Rhodophyta, 22 Ochrophyta, 15 Chlorophyta) de algas bentónicas marinas recolectadas en el intermareal y submareal de más de 80 localidades de las costas atlánticas y cantábricas de la Península Ibérica. Polysiphonia devoniensis, P. fibrata y Zonaria tournefortii son novedad para Portugal y 5 especies (Bonnemaisonia hamifera, Calosiphonia vermicularis, P. devoniensis, Hincksia intermedia y Derbesia marina stadium Halicystis ovalis) son nuevas citas para Galicia. Paralelamente, se aportan 101 primeras citas provinciales (2 Guipúzcoa, 1 Vizcaya, 8 Cantabria, 5 Asturias, 7 Lugo, 1 A Coruña, 8 Pontevedra, 1 Beira litoral, 15 Estremadura, 20 Alentejo, 25 Algarve y 8 Cádiz) y, además, se dan a conocer 108 segundas citas provinciales. Aunque la flora bentónica marina del Atlántico Peninsular ha sido objeto de numerosos estudios, estos nuevos hallazgos corológicos ponen en evidencia que todavía son necesarios más estudios florísticos en estas costas.English.  In this work, we provide new records and geographical distribution data for 98 seaweeds (61 Rhodophyta, 22 Ochrophyta, 15 Chlorophyta) inhabiting more than 80 sites (intertidal and subtidal) of the Atlantic Iberian Peninsula. Polysiphonia devoniensis, P. fibrata y Zonaria tournefortii are new records for Portugal and 5 species (Bonnemaisonia hamifera, Calosiphonia vermicularis, P. devoniensis, Hincksia intermedia and Derbesia marina stadium Halicystis ovalis) are new records for Galicia. Moreover, 101 new records are reported for the first time in the studied provinces (2 Guipúzcoa, 1 Vizcaya, 8 Cantabria, 5 Asturias, 7 Lugo, 1 A Coruña, 8 Pontevedra, 1 Beira litoral, 15 Estremadura, 20 Alentejo, 25 Algarve y 8 Cádiz) and 108 for the second time. Although the Atlantic marine algae of the Iberian Peninsula are well studied, these new findings show that further floristic studies are necessary to complete our knowledge of the natural heritage of this region.
