Investigating a simplified method for noninvasive genetic sampling in East African mammals using silica dried scat swabs

2020

Abstract Swabbing scat has proved to be an effective noninvasive method to collect DNA from mammals in the field. Previously, this method has relied on preservative liquids or freezing to preserve the DNA collected on swabs. In this study, we determine the effectiveness of using silica to simply dry the swab in field as an alternative way to prevent DNA degredation. Four species were included in the study; reticulated giraffe, impala, fringe‐eared oryx, and lion. Swabs were taken at multiple time points for giraffe and impala scat samples, with the lion and oryx sampled opportunistically. Mitochondrial DNA was successfully amplified and sequenced from scat swabs from all species; however, e…

Growth form matters – Crustose lichens on dead wood are sensitive to forest management

2022

Lichens have a vital role in forest ecosystems and they are a threatened group in boreal forests. However, the conservation ecology of the total lichen community has very rarely been studied. Here we studied lichen species and communities, including macrolichens (=foliose and fruticose growth forms) and rarely studied crustose li-chens, on decaying wood in boreal spruce-dominated forests in Finland. We also studied obligate lignicoles that grow only on dead wood and are mostly crustose in growth form. Species richness and community composition were examined on decaying logs and natural or cut stumps of Picea abies at different decay stages (2-5) in 14 stands, half of which were natural or s…

Maza uzņēmuma IT infrastruktūras pilnveidošana

2017

Kvalifikācijas darba mērķis ir izpētīt maza uzņēmuma IT infrastruktūru, piedāvāt un ieviest risinājumus, kas uzlabotu tās pārskatāmību un pārvaldību. Šī mērķa sasniegšanai uzņēmumā tika ieviesti sekojoši risinājumi - VMware virtualizācijas platforma un Ubuntu Landscape centralizētās vadības sistēma, kā arī uzlabotas iespējas veikt rezerves kopiju veidošanu un uzņēmuma sistēmu pārraudzību. Darba rezultātā sasniegtais samazināja laika un darba apjomu, kas nepieciešams uzņēmuma IT infrastruktūras uzturēšanai.

Crónica de una pandemia: confinamiento en Castelló de la Plana, España

2021

Este artículo presenta los resultados de una investigación comenzada a raíz de la declaración del estado de alarma en España (Real Decreto [RD] No. 463/2020, de 14 de marzo) después que la Organización Mundial de la Salud (OMS) declarase la enfermedad por coronavirus 2019 (COVID-19) como pandemia el día 11 de marzo de 2020. Este decreto limitaba la libre circulación de las personas, así como el derecho de reunión, tanto en lugares públicos como privados, además de imponer la obligatoriedad de mantener una distancia de seguridad entre los individuos y la limitación del aforo en aquellos establecimientos que permanecían abiertos, entre otras medidas. Todo ello supuso un cambioen las rutinas d…

Equilibrium properties of the reaction H2⇌ 2H by classical molecular dynamics simulations

2013

We have developed a classical molecular dynamics model for the hydrogen dissociation reaction, containing two- and three-particle potentials derived by Kohen, Tully and Stillinger. Two fluid densities were investigated for a wide range of temperatures, and 11 fluid densities were considered for one temperature. We report the temperature range where the degree of reaction is significant, and also where a stable molecule dominates the population in the energy landscape. The three-particle potential, which is essential for the reaction model and seldom studied, together with the two-particle interaction lead to a large effective excluded volume diameter of the molecules in the molecular fluid.…

Architettura in alzato. Questioni di territorio, paesaggio, ambiente

2021

Negata alla tipologia l’architettura del Sud nel saggio riconosce una specifica identità e perfetta eccezionalità nell’essenza del luogo. Se la facciata istituisce un rapporto con l’estetica del paesaggio, i temi che essa sottende definiscono altre significative relazioni. L’ordinamento logico delle membrature, la chiarezza geometrica e il rigore dei rapporti rimandano ad una architettura che si misura, ed è misura stessa, del territorio e della sua morfologia. A sua volta, lo spessore della facciata esprime la relazione con l’ambiente e interpreta in maniera poetica i condizionamenti climatici, intervenendo sul controllo della luce, sui vuoti nei paramenti murari, sulla determinazione dell…

Linguistic Landscape geht digital: „Virtuelle sprachliche Landschaften“ auf Instagram am Beispiel der Weinstraßen in zwei mehrsprachigen Regionen (El…

2021

International audience; Kontext Die heutige Digitalisierung der Kommunikation wirft ein neues Licht auf traditionelle LL-Praktiken und -Problemstellungen (Androutsopoulos 2014). In Anschluss an Ivkovic & Lotherington (2009) und auf der Pilotstudie von Hiipala et al. (2019) aufbauend kann ein neuer Strang in der LL-Forschung identifiziert werden, der den gut etablierten LL-Begriff auf digitale und virtuelle Räume auszudehnen versucht, wie an der Prägung des Begriffs „virtuelle sprachliche Landschaft“ abgelesen werden kann. Parallel dazu werden soziale Netzwerke heutzutage immer mehr in touristischen Kontexten verwendet, an erster Stelle von Touristinnen, die somit – und meistens unmittelba…

Land unit definition for potential distribution of endangered species

2010

In Europe several mapping techniques exist to lay out plant distribution. Most of them, however, are focused on actual and not on potential species distribution range. Spatial predictions become more important for rare and endangered taxa because their conservation is related to existing as well as potential biotopes. The large part of detailed distribution models applies advanced statistics on a large data-set of environmental variables. Data-input availability limits the choice of the prediction model for species distribution and application of results in a detailed scale. Distribution pattern accuracy determinates its applicability in environmental management (for tracing edges, defining…
