Contribution to the knowledge of the mosquitoes in the Devesa of Racó de l Olla, Albufera Natural Park of Valencia (Spain)
2017
[ES] Se presenta una recopilación de los resultados de varios proyectos, desarrollados entre los años 2004 y 2015, sobre la presencia de los mosquitos de la familia Culicidae en el entorno de la Devesa y el Racó de l¿Olla del Parque Natural de l¿Albufera de Valencia (España). Se registró un total de 10 especies pertenecientes a cinco géneros (Aedes, Coquillettidia, Culex, Culiseta y Ochlerotatus), alguno de estos muy característicos de los ambientes donde fueron recolectados. Se tratan diferentes aspectos sobre la diversidad de culícidos, así como del interés ecológico y sanitario de la presencia de los mismos. Destacamos la existencia de la especie Aedes albopictus (Skuse, 1894) en un espa…
Multimorbidity increases the risk of dementia: a 15 year follow-up of the SHARE study.
2023
Abstract Aims the literature regarding the association between multimorbidity and dementia is still unclear. Therefore, we aimed to explore the potential association between multimorbidity at the baseline and the risk of future dementia in the SHARE (Survey of Health, Ageing and Retirement in Europe) study, a large European research survey, with a follow-up of 15 years. Methods in this longitudinal study, multimorbidity was defined as the presence of two or more chronic medical conditions, among 14 self-reported at the baseline evaluation. Incident dementia was ascertained using self-reported information. Cox regression analysis, adjusted for potential confounders, was run and hazard ratios…
Pain perception in Parkinson's disease: A systematic review and meta-analysis of experimental studies
2017
While hyperalgesia (increased pain sensitivity) has been suggested to contribute to the increased prevalence of clinical pain in Parkinson's disease (PD), experimental research is equivocal and mechanisms are poorly understood. We conducted a meta-analysis of studies comparing PD patients to healthy controls (HCs) in their response to experimental pain stimuli. Articles were acquired through systematic searches of major databases from inception until 10/2016. Twenty-six studies met inclusion criteria, comprising 1292 participants (PD = 739, HCs = 553). Random effects meta-analysis of standardized mean differences (SMD) revealed lower pain threshold (indicating hyperalgesia) in PD patients d…
Carbon stable isotope composition of charophyte organic matter in a small and shallow Spanish water body as a baseline for future trophic studies
2015
<p>Quantitative descriptions of foodweb structure based on isotope niche space require knowledge of producers’ isotopic signatures. In freshwater ecosystems charophytes are one of the main components of submerged vegetation and the feeding base for many herbivorous consumers, but knowledge about their organic carbon isotopic signatures is sparse. In this study, the δ<sup>13</sup>C organic values (and organic %C and %N) of the four species of submerged macrophytes (three charophytes - <em>Chara hispida</em>, <em>Nitella hyalina</em> and <em>Tolypella glomerata </em>- and one angiosperm, <em>Myriophyllum spicatum</em>) growing …
Amphibians of the Kayan Mentarang National Park (East Kalimantan, Indonesia): estimating overall and local species richness
2004
On the basis of surveys since 1997 and an intensive survey at the World Wildlife Fund field station at Lalut Birai in 2001, we assessed the importance of the Kayan Mentarang National Park in East Kalimantan for the conservation of Borneo's amphibian fauna. Sixty-five frog species and one Caecilian species are currently known to occur in this region. We report their occurrence in 16 subareas. Most of the species were recorded at Upper Bahau (41) and at the Lalut Birai field station (33). Based on the results of opportunistic searches and transect censuses at Lalut Birai, we argue that the amphibian diversity of the national park is still greatly underestimated.
Animal Perception of Seasonal Thresholds: Changes in Elephant Movement in Relation to Rainfall Patterns
2012
Background The identification of temporal thresholds or shifts in animal movement informs ecologists of changes in an animal’s behaviour, which contributes to an understanding of species’ responses in different environments. In African savannas, rainfall, temperature and primary productivity influence the movements of large herbivores and drive changes at different scales. Here, we developed a novel approach to define seasonal shifts in movement behaviour by examining the movements of a highly mobile herbivore (elephant; Loxodonta africana), in relation to local and regional rainfall patterns. Methodology/Principal Findings We used speed to determine movement changes of between 8 and 14 GPS…
40 Years of Breeding Bird Community Dynamics in a Primeval Temperate Forest (Białowieża National Park, Poland)
2015
We documented the composition and structure of the breeding bird assemblage in the primeval temperate forest of the Bialowieza National Park (BNP), during 2010-2014, and used 40 years of data to assess patterns of its diver- sity. We applied an improved version of the mapping technique (a combined mapping method) for forest birds in seven plots located in three old-growth forest types: ash-alder riverine, oak-hornbeam, and mixed coniferous. The composi- tion of the breeding avifauna and species richness remained basically unchanged. Jointly 67 (79% of 40-year total) breeding species were recorded in 2010-2014. Overall 49 (57%) of all species bred in the study plots in more than 35 years, th…
Materiały do poznania fauny Kampinoskiego Parku Narodowego: Apionidae i Nanophyidae (Coleoptera: Curculionoidea)
2013
New localities of 35 species of Apionidae and 2 species of Nanophyidae in the Kampinos National Park are presented, among them respectively 26 and 2 species new for the studied area. Regarding Apionidae, 8 of 9 species recorded from the Kampinos National Park in literature, were confirmed to occur there. Perapion oblongum (GYLL.) has been recorded from the Mazovian Lowland for the first time
Neuronal cell cycle: the neuron itself and its circumstances.
2015
Neurons are usually regarded as postmitotic cells that undergo apoptosis in response to cell cycle reactivation. Nevertheless, recent evidence indicates the existence of a defined developmental program that induces DNA replication in specific populations of neurons, which remain in a tetraploid state for the rest of their adult life. Similarly, de novo neuronal tetraploidization has also been described in the adult brain as an early hallmark of neurodegeneration. The aim of this review is to integrate these recent developments in the context of cell cycle regulation and apoptotic cell death in neurons. We conclude that a variety of mechanisms exists in neuronal cells for G1/S and G2/M check…
