The interstitial subsoil fauna on the beach of Sarso Island, Red Sea

The scope of this research was to find out, how important is the presence of brackish water for the formation of the characteristical littoral subsoil fauna in the interstitial spaces of beaches. There is little precipitation in the Red Sea area and therefore little influence of freshwater on the beach. Moreover, the sandy beach of Sarso Island (Farasan Archipelago) is bordered landwards and underneath by solid limestone, preventing subsoil fresh water, if there is any, from penetrating into the beach region. The salinity of the interstitial water from Sarso beach lies a little above the salinity of the adjacent sea. The microfauna of Sarso beach is composed to a rather big proportion of such species that are known to be characteristical littoral subsoil water species, partially of world wide distribution. The ecological analysis of this fauna, i.e. the freeliving Nematodes, reveals the presence of two distinct associations: 1. the association of the low level subsoil region, close to the sea, with clear interstitial water, subject to regular exchange with the water of the adjcent sea. 2. the association of the high level subsoil region, 4-10 meter distant from the sea, with brownish water. Contrary to earlier results there is no distinction in salinity between the two associations, so it is not longer justified to apply the term brackish water fauna on the animals living in the association of the high level subsoil region.

Adsorption study for removal of basic red dye using bentonite

Colored wastewater poses a challenge to the conventional wastewater treatment techniques. Solid-liquid phase adsorption has been found to be effective for the removal of dyes from effluent. In this paper, the ability of bentonite as an adsorbent for the removal of a commercial dye, Basic Red 2 (BR2), from an aqueous solution has been investigated under various experimental conditions. The adsorption kinetics was shown to be pseudo-second-order. It was found that bentonite had high adsorption capacity for BR2 due to cation exchange. The adsorption equilibrium data can be fitted well by the Langmuir adsorption isotherm model. The effect of the experimental parameters, such as temperature, salt, and pH was investigated through a number of batch adsorption experiments. It was found that the removal of dye increased with the increase in solution pH. However, the change of temperature (15-45 degrees C) and the addition of sodium chloride were found to have little effect on the adsorption process. The results show that electrostatic interactions are not dominant in the interaction between BR2 and bentonite. It was found that the adsorption was a rapid process with 80-90% of the dye removed within the first 2-3 min. Bentonite as an adsorbent is promising for color removal from wastewater.

Assessing the Legacy of Red Mud Pollution in a Shallow Freshwater Lake: Arsenic Accumulation and Speciation in Macrophytes

Little is known about long-term ecological responses in lakes following red mud pollution. Among red mud contaminants, arsenic (As) is of considerable concern. Determination of the species of As accumulated in aquatic organisms provides important information about the biogeochemical cycling of the element and transfer through the aquatic food-web to higher organisms. We used coupled ion chromatography and inductively coupled plasma mass spectrometry (ICP-MS) to assess As speciation in tissues of five macrophyte taxa in Kinghorn Loch, UK, 30 years following the diversion of red mud pollution from the lake. Toxic inorganic As was the dominant species in the studied macrophytes, with As species concentrations varying with macrophyte taxon and tissue type. The highest As content measured in roots of Persicaria amphibia (L.) Gray (87.2 mg kg-1) greatly exceeded the 3 - 10 mg kg-1 range suggested as a potential phytotoxic level. Accumulation of toxic As species by plants suggested toxicological risk to higher organisms known to utilise macrophytes as a food source.

Little raven (Corvus mellori) as an egg predator of other bird species

 Little ravens were major predators of ground-nesting red-capped Plover and burrow-nesting Little penguin eggs. Ravens also congregated at the breeding sites of these two species to exploit eggs. As raven numbers increase with human habitation of land, their impact on other bird species needs to be monitored and managed.

Evidence of shared bovine viral diarrhea infections between red deer and extensively raised cattle in south-central Spain

Bovine viral diarrhea virus (BVDV) is a pestivirus that affects cattle production worldwide and that can infect other ungulates such as cervids and even wild boar (Sus scrofa). It is believed that domestic livestock can become infected through contact with wild animals, though it is known that infection can spread among wild animals in the absence of contact with livestock. Little is known about the sharing of BVDV infection between wild and domestic animals in the same habitat, which is important for designing eradication campaigns and preventing outbreaks, especially on hunting estates with high animal densities.

Entre el terrorismo y el terrorismo en red, un debate a propósito de los lobos solitarios en Estados Unidos (2001-2014)

El interés de esta disertación es otorgar una respuesta a la fenomenología del Lobo Solitario, que se alza como amenaza frente a los Estados, y es necesaria su correcta comprensión para poder contrarrestar sus efectos sobre la sociedad. De esta manera, se propone un debate entre los conceptos de terrorismo expuesto por un lado por Bruce Hoffman, y por el otro por Luis de la Corte Ibáñez, quienes aportarán herramientas de análisis para lograr entender la fenomenología. Para terminar proponiendo la teoría de redes, expuesta por Arquilla y Ronfeldt y Charles Perrow, como mecanismo de solución a la brecha conceptual existente, definiendo a los lobos solitarios a nivel operacional como nodos sin red, y a nivel de adoctrinamiento como redes de débil acople.

From illiteracy to literacy in adult- hood: A microlongitudinal study

Little is known about literacy acquisition in adults. Yet, our former studies suggest that the majority of the changes induced by literacy in children also occur in adulthood. Based on this observation as well as on what we know from developmental studies on reading acquisition, we designed an intensive literacy course in which each difficulty (either phono- logical or visual) of the alphabetic code is introduced in turn in lessons dedicated to overcoming it. We applied this course for 3 1∕2 months to 9 adult Portuguese illiterates. They were tested five times: two before starting the course (pre-tests), two during the course, and just after they completed the course. We tracked their evolution in reading and writing, metaphonology, memory for spoken nonwords, speech in noise perception, and visual abilities, including mirror-image discrimination. Most participants learned to read and write and showed associated enhancements in several domains, in particular in phonological skills.
