Naturalising the Highlands: geographies of mountain fieldwork in late-Victorian Scotland

Through a detailed examination of two late-Victorian field clubs dedicated to the exploration of alpine botany in the Scottish Highlands, this paper contributes to work on the historical geographies of civic science. By focusing on the scientific and social character of mountain fieldwork it analyses the reciprocal relations between the spaces, practices and science of Highland botanising and wider concerns with sociability, character and civic virtue. In so doing it investigates the transposition of a variety of discursive resources from evolutionism to tourism into the language and practices of botanical science. This focus enables the paper to complicate more general accounts of natural history in the Victorian period and to consider a number of methodological issues relevant to reconstructing the historical geographies of science.

Reception and schooling of children in schools in Catalonia: Beyond Educational Welcome Facilities

The ways of incorporating newcoming students into schools and colleges have been at the center of debate in most OECD countries in recent years. In Spain, the set of measures developed for the reception of immigrant pupils in different Autonomous Communities has also been the subject of specific research, pointing out the similarities and contradictions between pedagogic discourses and school practices. This article takes into account these considerations and presents the reflections from the results of research on the Educational Welcome Facilities (and specifically the EBE) conducted during the school years 2008-2010. This device was created in Catalonia to attend newcomers before enrolling them in the school. It was a pilot project which took place in Vic and Reus for two consecutive years. The research of the EBE has enabled us to explain the relationship between educational assessment that schools made about this facility and reception processes that schools were implementing. The conclusions that emerge from this analysis allowed us to establish relationships between educational host practices of the seven centers analyzed with three different conceptual and educational frameworks of reception.

Monkey mountain as a megazoo: analysing the naturalistic claims of “wild monkey parks” in Japan

In Japan yaen koen or ‘wild monkey parks’ are popular visitor attractions that show free-ranging monkey troops to the paying public. Unlike zoos, which display animals through confinement, monkey parks control the movements of the monkeys through provisioning. The parks project an image of themselves as ‘natural zoos’, claiming to practice a more authentic form of wild animal display than that practiced by the zoo. This article critically evaluates the monkey park’s claim by examining park management of the monkeys. The monkey park’s claim to display ‘wild monkeys’ is shown to be questionable because of the way that provisioning changes monkey behaviour. Against the background of human encroachment onto the forest habitat of the monkey, the long-term effect of provisioning is to sedentarize what were nomadic monkeys and to turn the ‘wild monkey park’ into a megazoo.

Increased cerebral output of free radicals during hypoxia: implications for acute mountain sickness?

Bailey DM, Taudorf S, Berg RMG, Lundby C, McEneny J, Young IS, Evans KA, James PE, Shore A, Hullin DA, McCord JM, Pedersen BK, Moller K. Increased cerebral output of free radicals during hypoxia: implications for acute mountain sickness? Am J Physiol Regul Integr Comp Physiol 297: R1283-R1292, 2009. First published September 2, 2009; doi: 10.1152/ajpregu.00366.2009.-This study examined whether hypoxia causes free radical-mediated disruption of the blood-brain barrier (BBB) and impaired cerebral oxidative metabolism and whether this has any bearing on neurological symptoms ascribed to acute mountain sickness (AMS). Ten men provided internal jugular vein and radial artery blood samples during normoxia and 9-h passive exposure to hypoxia (12.9% O-2). Cerebral blood flow was determined by the Kety-Schmidt technique with net exchange calculated by the Fick principle. AMS and headache were determined with clinically validated questionnaires. Electron paramagnetic resonance spectroscopy and ozone-based chemiluminescence were employed for direct detection of spin-trapped free radicals and nitric oxide metabolites. Neuron-specific enolase (NSE), S100 beta, and 3-nitrotyrosine (3-NT) were determined by ELISA. Hypoxia increased the arterio-jugular venous concentration difference (a-v(D)) and net cerebral output of lipid-derived alkoxyl-alkyl free radicals and lipid hydroperoxides (P

Antimicrobial peptides from the skin secretion of the Wuyi Mountain torrent frog, Amolops wuyiensis: An inhabitant of a pristine aquatic environment

The antimicrobial peptides of amphibian skin secretions are proposed to aid survival in microbe-rich environments. While many amphibians inhabit such environments, other such as the Wuyi Mountain torrent frog, Amolops wuyiensis, live in pristine waters flowing from underground mountain springs. This species thus represents an interesting model in which to study antimicrobial peptides. “Shotgun” cloning of a skin-derived cDNA library from this species identified transcripts encoding a brevinin-1 and a ranatuerin-2. Peptides with coincident molecular masses to both predicted mature peptides were identified in HPLC fractions of skin secretion. Synthetic replicates of both peptides were generated by solid-phase peptide synthesis and tested for activity using Staphylococcus aureus, Escherichia coli and Candida albicans. The brevinin was found to be broad-spectrum and potent with minimum inhibitory concentrations (MICs) of 24 µM (Sa), 5 µM (Ec) and 20 µM (Ca). In contrast, the ranatuerin was less effective and of narrower spectrum with an MIC > 200 µM for Sa, 40 µM (Ec) and 120 µM (Ca). Thus this species of amphibian that lives in a pristine environment does indeed possess at least one potent and broad-spectrum antimicrobial peptide in its skin secretion arsenal. This phenomenon could be explained in several ways. Firstly, it may represent an ancestral peptide required when the stem species inhabited microbe-rich environments. However, there is mounting evidence for the second reason, that suggests the function of such peptides is not primarily in antimicrobial defence.
