Data from: Grazing decreases N partitioning among coexisting plant species

2018

1. Herbivores play a key role in shaping ecosystem structure and functions by influencing plant and microbial community composition and nutrient cycling. 2. This study investigated the long-term effects of herbivores on plant resource acquisition. We explored differences in the natural δ15N signatures in plant, microbial and soil N pools, and examined mycorrhizal colonization in two tundra sites that have been either lightly or heavily grazed by reindeer for more than 50 years. The study examined changes in nutrient acquisition in five common tundra plants with contrasting traits and mycorrhiza status; the mycorrhizal dwarf shrubs, Betula nana, Vaccinium myrtillus and Empetrum hermaphroditu…

Data from: Evidence for an association between post-fledging dispersal and microsatellite multilocus heterozygosity in a large population of greater …

2014

Dispersal can be divided into three stages: departure, transience and settlement. Despite the fact that theoretical studies have emphasized the importance of heterozygosity on dispersal strategies, empirical evidence of its effect on different stages of dispersal is lacking. Here, using multi-event capture-mark-recapture models, we show a negative association between microsatellite multilocus heterozygosity (MLH; 10 loci; n = 1023) and post-fledging dispersal propensity for greater flamingos, Phoenicopterus roseus, born in southern France. We propose that the negative effects of inbreeding depression affects competitive ability and therefore more homozygous individuals are more likely to di…

Data from: Oxygen and carbon isoscapes for the Baltic Sea: testing their applicability in fish migration studies

2018

Conventional tags applied to individuals have been used to investigate animal movement, but these methods require tagged individuals be recaptured. Maps of regional isotopic variability known as “isoscapes” offer potential for various applications in migration research without tagging wherein isotope values of tissues are compared to environmental isotope values. In this study, we present the spatial variability in oxygen (math formula) and dissolved inorganic carbon (δ13CDIC) isotope values of Baltic Sea water. We also provide an example of how these isoscapes can reveal locations of individual animal via spatial probability surface maps, using the high-resolution salmon otolith isotope da…

Granulocyte Activity Is Enhanced by Culture Supernatants of Mononuclear Leukocytes Incubated with Tetrachlorodecaoxide

1995

Granulocytes (polymorphonuclear leukocytes, PMNs) and monocytes/ macrophages are important in wound healing. Within the first few hours PMNs and monocytes begin to infiltrate sites of injury. The major function of PMNs is to kill microbes and phagocytose cellular debris so that healing can proceed [1]. Monocytes/macrophages invading the wound are also active in phagocytosis. In addition they release a number of cytokines including growth factors, interleukin-8 (IL-8), and tumor necrosis factor (TNF-α) needed for new tissue formation and shown to stimulate PMNs [1–3].

ESRA19-0692 Which preoperative tests before regional anaesthetic procedures?

2019

As we know, any regional anaesthesia technique stays under failure risks. What anaesthetists have to know about the regional block before let the surgeons start after regional anaesthesia? There are few positions which should be confirmed by tests. Firstly, detect the onset of successful sensitive, motor and sympathetic block. Secondly, confirm the correct area of the regional block. Furthermore, the anaesthetist should understand if the regional block performed under deep sedation or general anaesthesia will be effective also after the surgery. What we have to remember and what we need to check for this reason? Pain is subjective phenomenon. Are we determined as dependent on the patient‘s …

Über die Micromelerpetontidae (Amphibia: Temnospondyli). 1. Morphologie und Paläoökologie desMicromelerpeton credneri (Unter-Perm; SW-Deutschland)

1995

This paper presents a redescription of the most important features of the skull roof, palate, hyobranchial apparatus, and the postcranial skeleton ofMicromelerpeton credneri. It is possible to distinguish a temporal sequence of three morphotypes that can be differentiated by size and slight differences in the structure of the skull roof. They led a predaceous existence in the pelagial of three fairly deep lakes that had excellent potential for the preservation of fossils. Comparisons of the size-frequency distributions for specimens from different horizons indicate facultative paedomorphosis by means of progenesis. This phenomenon may be related to different trophic strategies and possible …

Superfood for axons: Glial exosomes boost axonal energetics by delivery of SIRT2

2021

Axon integrity depends on support by glia facilitating axonal maintenance and energy homeostasis, but the molecular mechanisms are not well understood. In this issue of Neuron, Chamberlain et al. (2021) provide evidence that oligodendrocyte-to-axon transfer of SIRT2 via extracellular vesicles (exosomes) enables deacetylation of mitochondrial proteins, enhancing axonal energy production.
