Seven new interesting records for the flora of Almería and Granada (Spain) are listed in this paper. Among them, Ferulago ternatifolia and Teucrium spinosum would be the most relevant cited species due to their rarity or their particular distribution areas. [ABSTRACT FROM AUTHOR]

Dry rivers (ramblas) are ecosystems of great relevance in the Segura Basin due to the extent they occupy. These ecosystems harbour plant communities characterized by the diversity and unique ness of the species that make it up. The objective of this paper is to analyze the biological traits that characterize these communities and relate them to its capacity to provide ecosystem services to society. The results obtained indicate that the plant communities of these ecosystems present clearly terrestrial and xerophilous biological traits with a dominance of phanerophytic and camephytic forms, with various adaptations to drought and a total absence of helophyte species. Furthermore, more than 90% of the species studied provide some ecosystem service. [ABSTRACT FROM AUTHOR]

14 new or interesting records for the flora of Albacete, Almeria and Granada are listed in this paper. For each species, chorological, taxonomic and ecology data are included. Furthermore, data belonging to their Conservation status are added, in order to take into account them in further revisions of Catalogues of threatened flora. [ABSTRACT FROM AUTHOR]

This paper is based on optical microscopy observations of phytoplankton samples collected from few water reservoirs at the shrimp cultures (Litopenaeus vannamei Boone, 1931) of Cultisur Enterprise, SE of Cuba. After further studies three species were studied, which were not found in Cuba before: Strombomonas borysteniensis (Roll) Popova (Euglenophyceae) and two cyanobacteria forming typical cyanobacterial water blooms: Anabaenopsis elenkinii Miller and a species of Glaucospira Lagerheim.The present paper offers descriptions and taxonomical comments about these species.

The main aim of this paper is report the first cited of an intersexual gonadal anomaly of Trachurus mediterraneus from the Alboran Sea (Western Mediterranean). This specimen is the first record of intersexuality in horse mackerel in the world. [ABSTRACT FROM AUTHOR]

A filamentous cyanobacteria was observed in plankton samples from Hanabanilla Reservoir (Central Cuba). Based on optical microscopy study, the Cuban specimens correspond with Limnoraphis robusta (Parakutty) Komárek et al. (Oscillatoriales) known from Africa, Brazil, India, Guatemala and North America. According to the literature consulted this taxon was not previously reported from Cuban freshwaters. The colonies of the Cuban population form clusters not the typical mats described for the species. The specimens are also characterized by smaller cells and trichomes. The present paper offers description of the Cuban population and data about its taxonomy, geographical distribution and ecology.

Translation of scientific terms to Spanish could bring confusion in many cases. In addition, the term by-catch (= bycatch), carry an added difficulty because it has inconsistency in its definition and transcription. In this paper the most common definitions of by-catch are reviewed, and a Spanish translation is proposed as "captura acompañante". We define by-catch as: "the components of the catch, taken during a fishing operation, which are not target species towards fishing effort is directed, and that may be retained on board or returned to the sea. Moreover, we proposed other translations and definition for relate words. [ABSTRACT FROM AUTHOR]

The review of 563 journals publishing new species worldwide and 14,263 references showed 5,745 new species of animals, plants and fungi which represents an average of 2.48 species per paper. In this compilation fossils are not considered, nor any other taxonomic level below the species. The type localities of the newly described species belong to 185 nations, with China, Brazil and Australia as the most recorded (1,829, 1,036 and 966 species, respectively). Even if there are consortia as State of Observed Species (SOS) that collect every year the number of new species around the world, there is not a publication where each country's contribution to global biodiversity is shown, an information that would allow the detection of bias in the biodiversity conservation efforts and the generation of taxonomic knowledge itself.

Since the review made by Mas (1986), knowledge about the distribution and population characteristics of freshwater fish from the Segura river basin has greatly improved. This paper presents the observed historical changes on species composition and the updated distribution of species in the sectors established in the mentioned review. The traits of the present fish communities reflect a marked degradation compared to the historical status. The number of species has significantly increased due to foreign species introduction. Turnover rate in species composition has been extremely high in less than 25 years, reaching a maximum in river sectors that have suffered greater impacts from pollution and habitat alteration.

The paper studies the age structure, back-calculated length and growth rate of Gobio lozanoi populations along the two main river axes of the Segura river basin (Segura and Mundo rivers). These parameters were analyzed from individuals captured in autumn 2009 and throughout 19 sampling locations, and their relationship with environmental variables (altitude, ecological status and conductivity). Populations showed six age classes (0+ to 5+) with few differences between sexes and dominance of intermediate ages (2+ and 3+). The age structure showed significant variations along the gradient with a tendency to narrower ranges of age in lower altitude locations. Growth rates showed a negative relationship with longevity and significant differences among fluvial sectors. The growth rate in the phase of transition to maturity showed a tendency to decrease with the gradient as well as the ecological state diminished and the water conductivity increased.

This paper presents short comments about the occurrence of 66 taxa recorded on different chorological units belonging to Toledo province, nine of them are remarked for first time in this area. For the remaining group its chorological knowledge is enhanced, or its presence is added to distribution data provided on Flora Iberica Project. [ABSTRACT FROM AUTHOR]
