    The names of southwestern European goats: is Iberian ibex the best common name for Capra pyrenaica? The common name designated to a species is important because it connects specialists with non–experts. The matter of the correct common name is relevant to the conservation and management of conspicuous or flag species. The English name "Spanish ibex" to designate Capra pyrenaica is extensive in the scientific literature, and some have defended its appropriateness. However, in our opinion, it is not the best term to designate this species. We propose that "Iberian wild goat" should be used. Herein, we review the etymology, history, taxonomy and public use of the names used to designate goats (domestic and wild) in southwestern Europe during the last two millennia. Used first by Pliny the Elder, the name "ibex" has been applied most often for the Alpine wild goat (C. ibex), and few authors applied this name to C. pyrenaica until the 20th century when some influential works extended its use in the scientific literature. Adult males of C. pyrenaica have lyre–shaped, and typically smooth horns that do not match the ibex morphotype, which has scimitar–shaped knotted horns. Although C. pyrenaica and C. ibex are probably phylogenetically close, their common names do not necessarily have to match. The rules of common names differ from those of scientific names. Cabra montés or cabra brava (wild goat) is the common name used by most authors in the Iberian peninsula. This name is deeply entrenched in the Iberian languages and has been used since the earliest references to the species in mediaeval times. We propose the adoption of "Iberian wild goat" for legal and scientific communication and when interacting with the media

    Integrating hydrological features and genetically validated occurrence data in occupancy modeling of an endemic and endangered semi-aquatic mammal species, Galemys pyrenaicus, in a Pyrenean catchment

    As freshwater habitats are among the most endangered, there is an urgent need to identify critical areas for conservation, especially those that are home to endangered species. The Pyrenean desman (Galemys pyrenaicus) is a semi-aquatic mammal whose basic ecological requirements are largely unknown, hindering adequate conservation planning even though it is considered as a threatened species. Species distribution modelling is challenging for freshwater species. Indeed, the complexity of aquatic ecosystems (e.g., linear and hierarchical ordering) must be taken into account as well as imperfect sampling. High-quality and relevant hydrological descriptors should also be used. To understand the influence of environmental covariates on the occupancy and detection of the Pyrenean desman, we combine both a robust sign-survey data set (i.e. with genetic validation ensuring true presence information) and a hydrological model to simulate the flow regime across a whole catchment. Markovian site-occupancy analysis, taking into account sign detection and based on spatially adjacent replicates, indicated a positive influence of heterogeneity of substrate and shelters, and a negative influence of flow variability on Pyrenean desman detection. This valuable information should help to improve monitoring programs for this endangered species. Our results also highlighted a spatially clustered distribution and a positive influence of stream flow and number of tributaries on occupancy. Hence, modifications of flow regime (e.g. hydropower production, irrigation, climate change) and habitat fragmentation appear to be major threats for this species, altering the connectivity between tributaries and the mainstream river as well as between adjacent sub-catchments

    Krüppel-Like Factor 6 Expression Changes during Trophoblast Syncytialization and Transactivates ßhCG and PSG Placental Genes

    BACKGROUND: Krüppel-like factor-6 (KLF6) is a widely expressed member of the Sp1/KLF family of transcriptional regulators involved in differentiation, cell cycle control and proliferation in several cell systems. Even though the highest expression level of KLF6 has been detected in human and mice placenta, its function in trophoblast physiology is still unknown. METHODOLOGY/PRINCIPAL FINDINGS: Herein, we explored KLF6 expression and sub-cellular distribution in human trophoblast cells differentiating into the syncytial pathway, and its role in the regulation of genes associated with placental development and pregnancy maintenance. Confocal immunofluorescence microscopy demonstrated that KLF6 is expressed throughout human cytotrophoblast differentiation showing no evident modifications in its nuclear and cytoplasmic localization pattern. KLF6 transcript and protein peaked early during the syncytialization process as determined by qRT-PCR and western blot assays. Overexpression of KLF6 in trophoblast-derived JEG-3 cells showed a preferential nuclear signal correlating with enhanced expression of human β-chorionic gonadotropin (βhCG) and pregnancy-specific glycoprotein (PSG) genes. Moreover, KLF6 transactivated βhCG5, PSG5 and PSG3 gene promoters. Deletion of KLF6 Zn-finger DNA binding domain or mutation of the consensus KLF6 binding site abolished transactivation of the PSG5 promoter. CONCLUSIONS/SIGNIFICANCE: Results are consistent with KLF6 playing a role as transcriptional regulator of relevant genes for placental differentiation and physiology such as βhCG and PSG, in agreement with an early and transient increase of KLF6 expression during trophoblast syncytialization

    Democratic experimentation in early childhood education

    Qualifications of the early years workforce are a salient predictors of quality and therefore of children’s outcomes. International reports advise that a majority of staff is trained at Bachelor’s levels and rank countries according to this criterion. There is fewer consensus on what this professionalism should be. In a majority of countries, large numbers of professionals are untrained, unqualified and sometimes invisible in the official reports. Many of these unqualified “assistants” take up crucial “care” tasks, while the teacher’s tasks are defined as “education”. The separation between care and education occurs in split systems as well as in systems where education and care are supposed to be integrated. In addition, the growing diversity of families challenges our preconceived ideas about “the good life” for children. These observations urge us to rethink professionalism in terms of reflexivity and the capacity of co-constructing pedagogy with parents and children. A case study in Ghent shows how low qualified professionals develop research capacities. The analysis of their experience suggests that “learning” may be less a quality of the individual than a quality of the systemic relationships that are build in the teams as well as in the interaction between teams and their social contexts

    Nest-building males trade-off material collection costs with territory value

    This work was supported by the BBSRC (BB/I019502/1 to SDH and SLM) and Roslin Institute Strategic Grant funding from the BBSRC (SLM).Building a structurally robust nest is crucial for reproductive success in many birds. However, we know little about the criteria birds use to select material or where they go to collect it. Here we observed the material collection of male Cape Weavers (Ploceus capensis). Males typically selected long, strong material to build their nests and each male collected material from different locations. Males that built more nests nested in a different area of the colony and flew further to collect nest material than did males that built fewer nests. As these males that flew further to collect material had longer tails and wings and attracted more females to their territories than did males that flew shorter distances, they may have traded off the travel costs of collecting nest materials with benefits gained from holding a territory in a more 'desirable' part of the colony. Nest construction, then, appears to be a multi-dimensional task whereby birds take into account material's structural properties, material proximity to the nest site and territory quality. Males that do this effectively both attract more mates and provide structurally sound nests for their young.Publisher PDFPeer reviewe
