Phororhacoidea or Phorusrhacoidea? A note on the nomenclature of the “terror birds”

The Phorusrhacidae, a group of large terrestrial carnivorous birds mostly known from the Cenozoic of South America, are often placed in a superfamily, for which the taxon name Phororhacoidea Patterson, 1941 is frequently used. However, according to the International Code of Zoological Nomenclature, Phororhacoidea is not valid. The proper taxon name at the superfamily level is Phorusrhacoidea Ameghino, 1889.     

Semisystematic nomenclature of brassinosteroids

The assignment of the trivial name to new isolated or detected brassinosteroid is based on the trivial names of seven different brassinosteroids, with names assigned according to the plant source from which they were first isolated. To avoid some observed mistakes in assigning trivial names to these compounds and the impractical constant usage of their systematic names, we propose a semisystematic nomenclature of brassinosteroids, in which (22R,23R)-2,3,22,23-tetrahydroxy-5-campestane, the trivial name of which is 6-deoxocastasterone, is considered the functional parent compound and is named brassinostane or brassinane. A set of rules for naming the remaining natural brassinosteroids is presented.     

Naming progastrin-derived peptides

The antral hormone gastrin continues to be in focus, because its hormonal and growth promoting effects are essential both for the function of the normal stomach and for the pathogenesis of major dyspeptic and neoplastic diseases. Deduction of the progastrin structure has improved the insight in the cellular synthesis of gastrin, but has also revealed that the biosynthetic machinery is complex, and, accordingly, that progastrin is processed to a multitude of more or less bioactive fragments. The naming of these fragments has, however, become inconsistent and confusing. Therefore, we propose a systematic nomenclature for progastrin-derived peptides of which there are three classes: (I) The gastrins with the evolutionary preserved tetrapeptide amide (Trp-Met-Asp-PheNH₂) at the C-terminus, which ensures high-affinity binding to the gastrin (CCK-B) receptor. Among the gastrins, gastrin-34 and gastrin-17 constitute the primary forms. (II) Processing intermediates, which are early products of progastrin that contain the structure of the primary gastrins within their sequence, but still cannot bind the gastrin receptor due to insufficient processing at their C-terminus. (III) Flanking fragments from the N- and C-termini of progastrin that do not contain any primary gastrin in their sequence, but nevertheless may undergo posttranslational processing. Each fragment can be specified with suffixes corresponding to the derived sequence in progastrin.     

Guidelines for consistent reporting of exchanges/to nature within life cycle inventories (LCI)

Data availability and data quality are still critical factors for successful LCA work. The SETAC-Europe LCA Working Group ‘Data Availability and Data Quality’ has therefore focused on ongoing developments toward a common data exchange format, public databases and accepted quality measures to find science-based solutions than can be widely accepted. A necessary prerequisite for the free flow and exchange of life cycle inventory (LCI) data and the comparability of LCIs is the consistent definition, nomenclature, and use of inventory parameters. This is the main subject of the subgroup ‘Recommended List of Exchanges’ that presents its results and findings here:

The type species of Apiognomonia, A. veneta, with its Discula anamorph is distinct from A. errabunda

Species of Apiognomonia with their Discula anamorphic states in the Gnomoniaceae, Diaporthales, are known throughout the temperate Northern Hemisphere and cause diseases such as sycamore or plane tree anthracnose. The genus Apiognomonia was described based on A. veneta as the type species; however, there has been disagreement about whether or not A. veneta is a synonym of A. errabunda. Using morphological, ecological, and DNA sequence data we conclude that A. errabunda and A. veneta are different species, although very closely related; thus, A. veneta is the correct name for the type species of Apiognomonia. This conclusion is based on a combined analysis of sequences from the ITS regions of nuclear rDNA for 51 isolates from host plants of eight genera and intron regions from actin, calmodulin and translation elongation factor 1-alpha for over 25 isolates. The type species of the genus Discula is D. nervisequa, the earliest available epithet for D. platani, the lectotype of Discula. D. nervisequa is the anamorph of A. veneta. Based on an examination of the type specimen, we determined that the commonly used name for the anamorph of A. errabunda, D. umbrinella, refers to another species. A. veneta and A. errabunda including their anamorphs are described and illustrated. An account of all synonyms and excluded synonyms is presented.     

Data standards, sense and stability: Scratchpads, the ICZN and ZooBank

The International Commission of Zoological Nomenclature has used the Scratchpads platform (currently being developed and maintained by ViBRANT) as the foundation for its redesigned website and as a platform for engaging with its users. The existing Scratchpad tools, with extensions to provide additional functions, have allowed for a major transformation in presentation of linked nomenclatural tools. Continued development of the new website will act as a springboard for the ICZN to participate more fully in the wider community of biodiversity informatics.     

European-wide GIS-based modelling system for quantifying the feedstock from Miscanthus and the potential contribution to renewable energy targets

Reliable estimates of feedstock resources are a prerequisite to the establishment of a biomass based-industry for energy and non food products. Field trials in the European Union (EU) show that Miscanthus spp. can produce high yields. Here we use a model (MISCANMOD) coupled with a GIS environment to estimate the contribution that Miscanthus could make to projected national electricity consumption. We describe the integration of different data sets, transformation procedures, and spatial analyses using GIS to produce energy statistics for the EU-25. Overall, Miscanthus grown on the 10% of arable land which is currently in set-aside could generate 282 TWh yr⁻¹ electricity. This would meet 39% of the EU-25 target of 723 TWh yr⁻¹ of electricity from renewable energy sources (RES) by 2010. As RES targets rise, land available for energy crops is also expected to increase. We consider three additional scenarios where Miscanthus could be grown on 10%, 20% and 35% of all agricultural land and we estimate it could generate respectively 345, 691 and 1209 TWh yr⁻¹ of electrical energy. At a national scale France, Poland and Germany have the highest potentials for Miscanthus production based on agricultural land area (respectively 83, 52, 49 TWh yr⁻¹ when 10% agricultural land is used). Finally, we reduced the scale to the EU NUTS2 (Nomenclature of Territorial Units for Statistics) regions to examine regional generation capacities. Key regions have been identified where national RES targets are exceeded. These regions could become net exporters of renewable energy.     

Amendment of Articles 8, 9, 10, 21 and 78 of the International Code of Zoological Nomenclature to expand and refine methods of publication

The International Commission on Zoological Nomenclature has voted in favour of a revised version of the amendment to the International Code of Zoological Nomenclature that was proposed in 2008. The purpose of the amendment is to expand and refine the methods of publication allowed by the Code, particularly in relation to electronic publication. The amendment establishes an Official Register of Zoological Nomenclature (with ZooBank as its online version), allows electronic publication after 2011 under certain conditions, and disallows publication on optical discs after 2012. The requirements for electronic publications are that the work be registered in ZooBank before it is published, that the work itself state the date of publication and contain evidence that registration has occurred, and that the ZooBank registration state both the name of an electronic archive intended to preserve the work and the ISSN or ISBN associated with the work. Registration of new scientific names and nomenclatural acts is not required. The Commission has confirmed that ZooBank is ready to handle the requirements of the amendment.
