Dedication of the a Cumberland Presbyterian church building, probably in Birmingham, Alabama
No full textThe congregation was part of the Springville Presbytery of the Alabama Synod. Rev. J. H. B. Hall, standing on the lowest step, was visiting the congregation for the event. Other identified men include James Sadler, R. P. Taylor, T. B. Nation, J. B. Stovall, John T. McCluney, Edward Thomas Sims, and John S. Hall (minister at the congregation). The date written on the back of the photograph appears to be July 13, 1900, but the last numeral is smudged (and could therefore denote a different year)

No full textSensitivity and Tolerance of Riparian Arthropod Communities to Altered Water Resources along a Drying River
No full textabstract: Background
Rivers around the world are drying with increasing frequency, but little is known about effects on terrestrial animal communities. Previous research along the San Pedro River in southeastern AZ, USA, suggests that changes in the availability of water resources associated with river drying lead to changes in predator abundance, community composition, diversity, and abundance of particular taxa of arthropods, but these observations have not yet been tested manipulatively.
Methods and Results
In this study, we constructed artificial pools in the stream bed adjacent to a drying section of the San Pedro River and maintained them as the river dried. We compared pitfall trapped arthropods near artificial pools to adjacent control sites where surface waters temporarily dried. Assemblage composition changed differentially at multiple taxonomic levels, resulting in different assemblages at pools than at control sites, with multiple taxa and richness of carabid beetle genera increasing at pools but not at controls that dried. On the other hand, predator biomass, particularly wolf spiders, and diversity of orders and families were consistently higher at control sites that dried. These results suggest an important role for colonization dynamics of pools, as well as the ability of certain taxa, particularly burrowing wolf spiders, to withstand periods of temporary drying.
Conclusions
Overall, we found some agreement between this manipulative study of water resources and a previous analysis of river drying that showed shifts in composition, changes in diversity, and declines in abundance of certain taxa (e.g. carabid beetles). However, colonization dynamics of pools, as well as compensatory strategies of predatory wolf spiders seem to have led to patterns that do not match previous research, with control sites maintaining high diversity, despite drying. Tolerance of river drying by some species may allow persistence of substantial diversity in the face of short-term drying. The long-term effects of drying remain to be investigated.The article is published at http://journals.plos.org/plosone/article?id=10.1371/journal.pone.010927

The Environmental Crisis and Humankind
No full textNeki ekološki orijentirani znanstvenici smatraju da smo prešli “točku nepovrata”, tj. stupanj na kojemu više ne možemo spriječiti ekološko propadanje. Usporiti ga možemo, ali zaustaviti ne možemo; daljnji razvitak vodi samo u propast. S obzirom na svoj odnos prema globalnom onečišćenju, ljudi se, prema McCluneyju, mogu podijeliti u tri skupine: fatalisti, koji vjeruju da je ekološka smrt naša posljednja postaja u tramvaju razvitka; tehnološki optimisti, koji tvrde da je ekološka kriza zacijelo pospješila razvitak tehnike i otkrila nam mnoge nove tehnologije, a tehnologija će nam riješiti sve probleme; holisti upozoravaju na krhkost ekološke ravnoteže na Zemlji: ispad samo jedne karike lako izazove lanac neugodnih promjena, pa moramo čuvati cjelokupan okoliš. Autor dodaje i skeptike: one koji sumnjaju da globalno zagrijavanje i njegove posljedice izaziva čovjek svojim djelovanjem, pa uzroke traže u različitim prirodnim događanjima (Sunčeve pjege, svemirske zrake, pomak Zemljine osi, biokemijski ciklusi prirodnih zbivanja itd.).
U nastavku teksta autor pokušava pronaći odgovor na pitanje zašto čovjek sâm sebe uništava, zašto u ekologiji otkazuju uobičajeni ljudski samozaštitni mehanizmi te kako to mijenjati — počevši od obiteljske i školske razine.Some environmentally-oriented scientists believe that we have passed the “point of no-return”, that is, the point beyond which environmental degradation may no longer be halted. It may be slowed down but not stopped: further development leads only to complete destruction.
In relation to their attitude towards global pollution, people may, according to McCluney, be divided into three groups: the fatalists, who believe that environmental death is our last stop on the train of development; the technological optimists, who claim that the environmental crisis must have stimulated the development of technology and unveiled many new technologies, and technology is the solution for all problems; the holists, who warn that environmental balance on the Earth is fragile: a single missing link may easily cause a sequence of unpleasant changes, which is why it is necessary
to preserve the environment in general. The author of the current paper also adds the sceptics: those who question the belief that global warming and its consequences have been caused by human activity, and therefore look for the causes in various events in nature (sunspots, radiation from the universe, the shifting of the Earth’s axis,
biochemical cycles of natural events, etc.).
In the remaining part of the paper, the author attempts to find the answer to the question why humankind is destroying itself, why the usual self-preservation instincts do not apply to the environment, and how to change this situation ‡ starting from families and schools
Remote sensing reflectance reconstruction to obtain water optical properties from MERIS multispectral satellite images
No full textWe use a multiple regression analysis and a data bank of about 400 reflectance spectra to reconstruct hyperspectral reflectances between 400 and 900 nm with a 5 nm step using only the values known at the wavelengths of the MERIS sensor level 2 data. For in situ remote sensing reflectances measured during different oceanographic missions, the reconstruction is within 2 per cent almost over the entire spectrum. The main difference (to a maximum of 4 per cent) usually occurs at the inflexion point of the reflectance curve between 580 and 600 nm. Observed in-situ remote sensing reflectances or reconstructed spectra are inverted using a Water Colour Simulator bio-optical model (WASI) to obtain the inherent optical properties (IOP) of the water. The values derived by the model are compared with the measurements when available. To validate the reconstruction, we compare the results of the model inversion using the initial spectrum or the reconstructed one as input. Preliminary results show that the derived values from the inversion of the reconstructed spectrum are very close to the values generated from the inversion of the initial spectrum, especially in case 1 waters. This reconstruction technique is used to generate hyperspectral remote sensing reflectances from reflectance data calculated by the MERIS sensor. We use the reconstructed spectra as input to be inverted in the WASI model in order to quantify the substances' concentrations; in particular, the inversion is working well for the suspended particulate matter concentrations
