Data compilation on the biological response to ocean acidification: environmental and experimental context of data sets and related literature

The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.

Diagramas de Ellingham e de Van't Hoff: algumas considerações

The main subject of this article is to show the parallelism betwen the Ellingham and Van't Hoff diagrams. The first one is a graphic representation of the changes in the standard Gibbs free energy (deltarGtheta) as a function of T and was introduced by Ellingham in 1944, in order to study metallurgic processes involving oxides and sulphides. On the other hand, the Van't Hoff diagram is a representation of the function ln K versus (1/T). The equivalence between both diagrams is easily demonstrated, making simple mathematical manipulations. In order to show the parallelism between both diagrams, they are presented briefly and two examples are discussed. The comparison of the both diagrams surely will be helpful to students and teachers in their learning and teaching activities, and will certainly enrich important aspects of chemical thermodynamics.

Alternative Analytical Expressions for the General van Genuchten-Mualem and van Genuchten-Burdine Hydraulic Conductivity Models

The van Genuchten expressions for the unsaturated soil hydraulic properties, first published in 1980, are used frequently in various vadose zone flow and transport applications assuming a specific relationship between the m and n soil hydraulic parameters. By comparison, probably because of the complexity of the hydraulic conductivity equations, the more general solutions with independent m and n values are rarely used. We expressed the general van Genuchten-Mualem and van Genuchten-Burdine hydraulic conductivity equations in terms of hypergeometric functions, which can be approximated by infinite series that converge rapidly for relatively large values of the van Genuchten-Mualem parameter n but only very slowly when n is close to one. Alternative equations were derived that provide very close approximations of the analytical results. The newly proposed equations allow the use of independent values of the parameters m and n in the soil water retention model of van Genuchten for subsequent prediction of the van Genuchten-Mualem and van Genuchten-Burdine hydraulic conductivity models, thus providing more flexibility in fitting experimental pressure-head-dependent water content, theta(h), and hydraulic conductivity, K(h), or K(theta) data.

Modeling of transpiration reduction in van Genuchten-Mualem type soils

We derive an analytic expression for the matric flux potential (M) for van Genuchten-Mualem (VGM) type soils which can also be written in terms of a converging infinite series. Considering the first four terms of this series, the accuracy of the approximation was verified by comparing it to values of M estimated by numerical finite difference integration. Using values of the parameters for three soils from different texture classes, the proposed four-term approximation showed an almost perfect match with the numerical solution, except for effective saturations higher than 0.9. Including more terms reduced the discrepancy but also increased the complexity of the equation. The four-term equation can be used for most applications. Cases with special interest in nearly saturated soils should include more terms from the infinite series. A transpiration reduction function for use with the VGM equations is derived by combining the derived expression for M with a root water extraction model. The shape of the resulting reduction function and its dependency on the derivative of the soil hydraulic diffusivity D with respect to the soil water content theta is discussed. Positive and negative values of dD/d theta yield concave and convex or S-shaped reduction functions, respectively. On the basis of three data sets, the hydraulic properties of virtually all soils yield concave reduction curves. Such curves based solely on soil hydraulic properties do not account for the complex interactions between shoot growth, root growth, and water availability.

A discussion on the Heteracanthocephalidae Petrochenko, 1956 (Acanthocephala : Palaeacanthocephala)

Several heteracanthocephalid specimens were recovered from the flatfish Rhombosolea leporina (Gunther), a host of Heteracanthocephalus peltorhamphi (Baylis, 1944) Petrochenko, 1956 from New Zealand. Unlike H. peltorhamphi, these new specimens have trunk spines. Measurements and proboscis armament of the new specimens are consistent with the worms being Aspersentis minor Edmonds & Smales, 1992 originally described from the Australian flounder Rhombosolea tapirina Gunther. A review of the family Heteracanthocephalidae Petrochenko, 1956 was undertaken to assess the validity of its four genera and eight species. The validity of Aspersentis megarhynchus (Linstow, 1892) Golvan, 1960 (syn. Echinorhynchus megarhynchus Linstow, 1892) is questioned. E. megarhynchus is not considered to be an heteracanthocephalid and is relegated to a species inquirenda. A. megarhynchus (Linstow, 1892) of Golvan (1960) nec E. megarhynchus Linstow, 1892 is considered a synonym of A. austrinus Van Cleave, 1929. The monotypic genus Heteracanthocephalus Petrochenko, 1956 is proposed as a synonym of Aspersentis Van Cleave, 1929 because there appear to be insufficient morphological differences between them. Aspersentis peltorhamphi n. comb. is proposed for Heteracanthocephalus peltorhamphi. The monotypic genus Sachalinorhynchus Krotov & Petrochenko in Petrochenko, 1956 is considered valid, but the other heteracanthocephalid genus, Bullockrhynchus Chandra, Rao & Shyamasundari, 1985, also monotypic, is not. B. indicus Chandra, Rao & Shyamasundari, 1985 possesses more features resembling rhadinorhynchids than heteracanthocephalids but only females are known, and therefore the genus and species cannot be placed. There are currently four valid species of Aspersentis and one of Sachalinorhynchus.

Spermatophore and Gonopore Morphology of the Southwestern-Atlantic Hermit Crab Pagurus exilis (Benedict, 1892) (Anomura, Paguridae)

Marcelo A. Scelzo, Marina Z. Fantucci, and Fernando L. Mantelatto (2010) Spermatophore and gonopore morphology of the southwestern-Atlantic hermit crab Pagurus exilis (Benedict, 1892) (Anomura, Paguridae). Zoological Studies 49(3): 421-433. The form and function of the spermatophore have been used as a complementary tool in studies of the reproductive biology and systematics of hermit crabs. In this context, we describe the spermatophore and gonopore morphology of Pagurus exilis. The spermatophores were extracted from the distal part of the vas deferens of specimens collected in Argentina and Brazil. The spermatophores were composed of 3 major regions: a main ampulla (with a sperm capsule inside and an accessory ampulla at the base), a stalk, and a pedestal. Each spermatophore had a distinct dorsolateral suture line around the ampulla, where the rupture occurs to release the sperm. The spermatophore total length was 1.5 times the main ampulla length. The main ampulla was oval and slightly flattened. A triangular accessory ampulla extended from the main ampulla base to the pedestal on 1 side, and contained no to several sperm. The stalk is short and flattened, and as wide as the main ampulla. One to 3 spermatophores were found attached to each pedestal, which was almost oblong in shape. The dimensions of the spermatophore and its component parts were directly influenced by the size of the hermit crab. Gonopores of males were covered by long pappose setae, while female gonopores bore a few short cuspidate setae. Specimens from Brazil and Argentina had the same spermatophore morphology, corroborating the previously observed absence of genetic differences between the both populations. The spermatophore morphology of this species has similarities with the broad general pattern of the Paguridae, being most similar to one of the (at least) 3 patterns of spermatophore morphology described for Pa gurus. http://zoolstud.sinica.edu.tw/Journals/49.3/421.pdf

Cor pulmonale in a patient with Brown-Vialetto-Van Laere syndrome: A case report

Brown-Vialetto-Van Laere syndrome (BVVLS) is a rare neurological disease characterized by sensorineural hearing loss and multiple cranial nerve palsies, usually involving the VIIth and IXth to XIIth cranial nerves. We describe the clinical and pathological features of a 33-year-old woman with BVVLS. The patient developed progressive exertional dyspnea, with clinical and laboratory findings of right-sided heart failure and pulmonary hypertension. She developed status epilepticus in the setting of cardiac deterioration and respiratory infection, and died of cardiogenic and septic shock. Autopsy disclosed bilateral neuronal loss and gliosis in the inferior colliculi, locus coeruleus and facial and vestibular nuclei. Cor pulmonale is a complication of hypoventilation-induced hypoxia and hypercapnia and had not yet been reported in BVVLS. (C) 2010 Elsevier B.V. All rights reserved.
