We describe a new assemblage of frog crabs (Raninoidea) from the lower Eocene Serraduy Formation in Huesca, Northeastern Spain, representing five species from five genera and four subfamilies, from which there are two new genera and four new species: i.e., Alloranina arjae gen. et sp. nov. (subfamily Ranininae), Huescarina vanbakeli gen. et sp. nov., Notopoides ovaloides sp. nov., Quasilaeviranina arafita sp. nov. (subfamily R...
This study describes temperature and precipitation trends in the two National Parks located in the two highest mountain ranges on the Iberian Peninsula: the Sierra Nevada (Sierra Nevada National Park, SN) and the Pyrenees (Aigüestortes i Sant Maurici National Park, ASM). Special focus is placed on analysing disparities between the lowlands and the highlands, as well as the agreement between observational data and grid data (IB...
Marine and extreme environments harbor a huge diversity of microorganisms able to produce new bioactive metabolites with beneficial health effects. In this study, ethanol, aqueous, methanol, and acetone extracts and protein hydrolysates were obtained from five different microalgae species and two haloarchaea. An in vitro study of cytotoxicity, migration, angiogenic effect, antioxidant capacity, and modulation of detoxifying en...
The Endangered Limpet Patella ferruginea Integrates a Metapopulation across the Species’ RangeOA Marine
The population genetics of Patella ferruginea Gmelin, 1791, an endangered limpet endemic to the western Mediterranean, has been analysed using 11 polymorphic microsatellite markers on 533 individuals from 18 localities throughout its distribution area. The results showed a deficit of heterozygotes, denoting a certain degree of inbreeding, and, with an overall FST of 0.004, a low level of genetic variability among localities. T...
Lindane removal by membrane nanofiltrationNARA Subscribed
The dynamics of cyclic populations distributed in space result from the relative strength of synchronising influences and the limited dispersal of destabilising factors (activators and inhibitors), known to cause multi‐annual population cycles. However, while each of these have been well studied in isolation, there is limited empirical evidence of how the processes of synchronisation and activation–inhibition act together, lar...
NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the NeotropicsNARA Subscribed
Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal specie...
Several reproductive issues and the larval development of the ferruginous limpet, Patella ferruginea Gmelin, 1791, an endangered species endemic from the western Mediterranean Sea, were studied to fill gaps in the knowledge of its life cycle.Average diameter of mature oocytes was 141.83 μm and mean oocyte density in the ovary was 283,800 oocytes/gram. No significant correlations were found between both oocyte diameter or densi...
