A new ascarid species in cynodont coprolite dated of 240 million years Anais da ABC (AABC)
SILVA,PRISCILLA A. DA; BORBA,VICTOR H.; DUTRA,JULIANA M.F.; LELES,DANIELA; DA-ROSA,ATILA A.S.; FERREIRA,LUIZ F.; ARAUJO,ADAUTO.
Cynodonts represent the transition from reptiles to mammals. They are classified as synapsids, or tetrapod animals with mammalian characteristics. We present here the finding of helminth eggs in a coprolite identified as of cynodont origin dated of nearly 240 million years. Microscopy revealed the presence of very well preserved intestinal parasite eggs. Up to now we identified an ascarid egg by morphological characteristics. Based on a previous description of the new genus Ascarites Poinar Jr and Boucot 2006 in coprolites of iguanodons from Belgium, we propose a new species,Ascarites rufferi n.sp. in cynodonts, a host that inhabited the Southern Region of Brazil in the Triassic period.

A new Mammutidae (Proboscidea, Mammalia) from the Late Miocene of Gansu Province, China Anais da ABC (AABC)
MOTHÉ,DIMILA; AVILLA,LEONARDO S.; ZHAO,DESI; XIE,GUANGPU; SUN,BOYANG.
ABSTRACT The "Yanghecun specimen", a proboscidean specimen represented by a mandible from Miocene of China and previously described as Gomphotheriidae, is here reviewed and described as a new genus and species of Mammutidae: Sinomammut tobieni. This taxon is a longirostrine mastodon, lacking lower tusks, and bearing a wide last molar with oblique and non-inflated lophids, broad transverse interlophids, and yoke-like wear figures. Phylogenetic analysis of Mammutidae based on dental and mandibular features recovered S. tobieni as sister group of the mastodon Mammut. The longirostrine condition and the well-developed lower incisors seem to be primitive for Mammutidae, while the brevirostry is the derived condition, probably emerged during the middle Miocene...

A protein with amino acid sequence homology to bovine insulin is present in the legume Vigna unguiculata (cowpea) BJMBR
Venâncio,T.M.; Oliveira,A.E.A.; Silva,L.B.; Machado,O.L.T.; Fernandes,K.V.S.; Xavier-Filho,J..
Since the discovery of bovine insulin in plants, much effort has been devoted to the characterization of these proteins and elucidation of their functions. We report here the isolation of a protein with similar molecular mass and same amino acid sequence to bovine insulin from developing fruits of cowpea (Vigna unguiculata) genotype Epace 10. Insulin was measured by ELISA using an anti-human insulin antibody and was detected both in empty pods and seed coats but not in the embryo. The highest concentrations (about 0.5 ng/µg of protein) of the protein were detected in seed coats at 16 and 18 days after pollination, and the values were 1.6 to 4.0 times higher than those found for isolated pods tested on any day. N-terminal amino acid sequencing of insulin...

A review of Chorthippus species with angled pronotal lateral keels from Greece with special reference to transitional populations between some Peloponnesean taxa (Orthoptera, Acrididae) Naturalis
Willemse, F.; Helversen, O. von; Odé, B..
This paper presents a summary of the current knowledge on the systematics of the Greek taxa of Chorthippus, morphologically characterised by angled lateral pronotal keels (usually grouped as Glyptobothrus). Prior to this paper, based on traditional morphology, ten taxa of Chorthippus with angled lateral pronotal keels were recognized from Greece. Based on morphology as well as (and more importantly so) bioacoustics thirteen Greek taxa are now recognised. With addition of a few additional related taxa that occur only outside Greece, all are treated in this paper: Chorthippus apricarius apricarius (Linnaeus, 1758), C. vagans vagans (Eversmann, 1848) (not in Greece), C. v. cypriotus (Uvarov, 1936) stat. nov.

A revision of the Genus Scincella (Reptilia: Sauria: Scincidae) of asia, with some notes on its evolution Naturalis
Ouboter, P.E..
Of the genus Scincella Mittleman, 1950 (sensu Greer, 1974) 337 specimens from Asia were examined for 74 characters, which were treated in a numerical-taxonomic way. The dendrogram resulting from this analysis was not stringently adhered to. Because of the wide variation in certain numerical scale characters within one taxon or even within one population, these characters (used by many authors as key characters to separate taxa) are not regarded as very important. For sympatric and parapatric species other characters, including relative size of head, body and limbs, are regarded as very important, because these characters are influenced by the way of life (niche separation). For the separation of allopatric species scale-numbers, but many other characters...

A structuralist approach in the study of evolution and classification Naturalis
Hammen, L. van der.
A survey is given of structuralism as a method that can be applied in the study of evolution and classification. The results of a structuralist approach are illustrated by examples from the laws underlying numerical changes, from the laws underlying changes in the chelicerate life-cycle, and from the laws underlying the evolution of the chelicerate appendages. Suggestions are given for the study of the laws underlying the transformation of form, and some notes are made on structuring forces and the early stages of organic evolution. Some concluding remarks are finally made on deep structure, phylogenetic classification and evolution.

A taxonomic revision of the Pleistocene Hystrix (Hystricidae, Rodentia) from Eurasia with notes on the evolution of the family Naturalis
Weers, D.J. van.
Measurements of many hundreds of the high-crowned cheek teeth of Hystrix specimens from the Euro-Asiatic Pleistocene in the collections of European and Asiatic institutions have been compared with extant species for a revision of the genus. A review is given about the extant genera and species of the family. The number of recognisable Euro-Asiatic species in the fossil record is reduced from eight to five. The European H. (A.) vinogradovi Argyropulo, 1941 is here considered to be a synonym of H. (A.) brachyura Linnaeus, 1758, and the three Asiatic species H. (H.) crassidens Lydekker, 1886, H. (H.) gigantea Van Weers, 1985 and H. (H.) magna Pei, 1987 are synonymized with H. (H.) refossa Gervais, 1852. Most of the Chinese fossil specimens are properly...

Acoustic evolution in crickets: need for phylogenetic study and a reappraisal of signal effectiveness Anais da ABC (AABC)
Desutter-Grandcolas,Laure; Robillard,Tony.
Cricket stridulums and calls are highly stereotyped, except those with greatly modified tegmina and/or vena-tion, or ''unusual'' frequency, duration and/or intensity. This acoustic diversity remained unsuspected until recently, and current models of acoustic evolution in crickets erroneously consider this clade homogeneous for acoustic features. The few phylogenetic studies analyzing acoustic evolution in crickets demonstrated that acoustic behavior could be particularly labile in some clades. The ensuing pattern for cricket evolution is consequently extremely complex. We argue that: (1) phylogeny should always be considered when analyzing acoustic evolution, whatever characters are considered (signals, stridulums or behaviors). Consequently, future...

Amazonia through time: Andean uplift, climate change, landscape evolution and biodiversity Naturalis
Hoorn, C.; Wesselingh, F.P.; Steege, H. ter; Bermudez, M.A.; Mora, A.; Sevink, J.; Sanmartín, I.; Sanchez-Meseguer, A.; Anderson, C.L.; Figueiredo, J.P.; Jaramillo, C.; Riff, D.; Negri, F.R.; Hooghiemstra, H.; Lundberg, J.; Stadler, T.; Särkinen, T.; Antonelli, A..
The Amazonian rainforest is arguably the most species-rich terrestrial ecosystem in the world, yet the timing of the origin and volutionary causes of this diversity are a matter of debate. We review the geologic and phylogenetic evidence from Amazonia and compare it with uplift records from the Andes. This uplift and its effect on regional climate fundamentally changed the Amazonian landscape by reconfiguring drainage patterns and creating a vast influx of sediments into the basin. On this “Andean” substrate, a region-wide edaphic mosaic developed that became extremely rich in species, particularly in Western Amazonia. We show that Andean uplift was crucial for the evolution of Amazonian landscapes and ecosystems, and that current biodiversity patterns...

AMP-deaminase in elasmobranch fish: A comparative histochemical and enzymatic study ArchiMer
Thebault, Marie-t; Izem, Lahoucine; Leroy, Jean Paul; Gobin, Eric; Charrier, Gregory; Raffin, Jean-paul.
AMP-deaminase activity was measured in white muscle from a wide range of fish, including one cyclostome, 13 chondrosteans, and one teleost to elucidate the pattern of the AMP-deaminase activity in white muscle of fish. Compared to a mammalian (rat) muscle extract, low enzyme activities are found in the cyclostome and two elasmobranchs from two families (Scyliorhinidae, Hexanchidae). In contrast, higher AMP-deaminase activities, similar to mammals, are expressed in Squalidae, all families of skates, Chimaeridae and in the teleostean fish. We then compared AMP-deaminase activities in red and white muscles from two representative elasmobranch fish, the dogfish (Scyliorhinus canicula) and the thornback ray (Raja clavata). The fibre type composition and...

An Emergent Economics of Ecosystem Management AgEcon
Hearnshaw, Edward J.S.; Cullen, Ross; Hughey, Kenneth F.D..
Economics is an evolving and emerging field of study, so is the management of ecosystems. As such, this paper delineates the co-evolution of economic evaluation that reflects the various recognized ecosystem management approaches of anticipative, adaptive and capacitive ecosystem management. Each management approach is critiqued and from this theoretical analysis an emergent approach for the management of ecosystem is put forward, which accordingly suggests an alternative methodological approach for economic evaluations.

An interesting new species of Sphaerocysta (Heteroptera, Tingidae) from Argentina, with the description of its ffth instar nymph Rev. Soc. Entomol. Argent.
Guidoti,Marcus; Montemayor,Sara I..
A new Neotropical species of Sphaerocysta Stål, (Hemiptera, Heteroptera, Tingidae) is described. Sphaerocysta costai n. sp. was collected in the Argentinian Yungas, in the provinces of Jujuy (Calilegua) and Salta (Urundel). The most important diagnostic characters are illustrated for adults and fifthinstar nymphs. This new species provides relevant evidence for the understanding of evolutionary trends within the family as its nymphal morphology exhibits unique features among Tingidae. Comments on the systematics of Sphaerocysta, and an identification key to its species are provided.

Analysis of castor bean ribosome-inactivating proteins and their gene expression during seed development Genet. Mol. Biol.
Loss-Morais,Guilherme; Turchetto-Zolet,Andreia Carina; Etges,Matheus; Cagliari,Alexandro; Körbes,Ana Paula; Maraschin,Felipe dos Santos; Margis-Pinheiro,Márcia; Margis,Rogério.
Ribosome-inactivating proteins (RIPs) are enzymes that inhibit protein synthesis after depurination of a specific adenine in rRNA. The RIP family members are classified as type I RIPs that contain an RNA-N-glycosidase domain and type II RIPs that contain a lectin domain (B chain) in addition to the glycosidase domain (A chain). In this work, we identified 30 new plant RIPs and characterized 18 Ricinus communis RIPs. Phylogenetic and functional divergence analyses indicated that the emergence of type I and II RIPs probably occurred before the monocot/eudicot split. We also report the expression profiles of 18 castor bean genes, including those for ricin and agglutinin, in five seed stages as assessed by quantitative PCR. Ricin and agglutinin were the most...

Anatomia comparada das folhas e evolução das Podocarpineae Acta Botanica
Woltz,Ph; Gajardo,R; Ferreira,A.G.
The anatomy of 112 species out of the 184 at present recognized is compared. The evolutionary sequence proposed shows in several different "series" the passage by successive transformations from an ancestral type with short one-nerved leaves, well-developed sub-epidermis and many resin canals to those with long wide leaves, first one-nerved then several-nerved, with reduced sub-epidermis and few resin canals. An over-evolved condition sometimes produces at the end of a "série" an apparent reversion to the ancestral type: leaves short or reduced to fleshy scales with late proliferation of canals separated in the mesophyll. A striking correlation between foliar anatomy and geographic latitude suggests, as with vascular evolution in seedlings at the cotyledon...

Aspects of the evolution and biogeography of stygobiontic Isopoda (Crustacea: Peracarida) Naturalis
Wägele, Johann-Wolfgang.
The evolution of the stygobiontic isopods is discussed correlating the phylogenetic system with biogeography. All stygobiontic isopods probably are derived from remote marine ancestors. The colonization of subterranean aquatic biotopes occurred in two ways: (1) via the coastal groundwater in the case of the Microparasellidae, Gnathostenetroididae, Stenetriidae, and in Cyathura (Stygocyathura), (2) in most families, however, via epigean freshwater ancestors. Ancient freshwater isopods that must already have existed before the Cretaceous and whose stygobiontic phylogenetic lines partly must have existed before the opening of the Atlantic are the Aselloidea, Calabozoida, Phreatoicidea, and probably also the Protojaniridae. In the course of Cretaceous and...

Balsaminaceae in Southeast Asia: systematics, evolution, and pollination biology Naturalis
Ruchisansakun, S..
Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity. Its classification has changed many times throughout the taxonomic history of the group, owing to the emphasis on particular diagnostic characters. This suggests that patterns of character evolution are labile and do not contain much phylogenetic signal. This appears particularly prevalent among floral characters, suggesting that floral evolution and pollination ecology may be important drivers of diversification in the family. Further complications in taxonomy arise from the fact that one of the two genera of the family, Impatiens, has a very large number of species, and that it is distributed across several continents. This has led to a lack of taxonomic...

Behavioral evidence for cone-based ultraviolet vision in divergent bat species and implications for its evolution Rev. Bras. Zool.
Fujun,Xuan; Kailiang,Hu; Tengteng,Zhu; Paul,Racey; Xuzhong,Wang; Yi,Sun.
We investigated the reactions of four bat species from four different lineages to UV light: Hipposideros armiger (Hodgson, 1835) and Scotophilus kuhlii Leach, 1821, which use constant frequency (CF) or frequency modulation (FM) echolocation, respectively; and Rousettus leschenaultii (Desmarest, 1820) and Cynopterus sphinx (Vahl, 1797), cave and tree-roosting Old World fruit bats, respectively. Following acclimation and training involving aversive stimuli when exposed to UV light, individuals of S. kuhlii and C. sphinx exposed to such stimuli displayed conditioned reflexes such as body crouching, wing retracting, horizontal crawling, flying and/or vocalization, whereas individuals of H. armiger and R. leschenaultii, in most cue-testing sessions, remained...

Beyond selection RChHN
VARGAS,ALEXANDER O.
It has been argued that the study of natural selection and quantitative genetics should have a central role in evolutionary thinking and undergraduate teaching in Chile. Extensive operational use of the concept of natural selection may seem consistent with this argument. However, advances of evolutionary knowledge in independent fields such as phylogenetic analysis, developmental evolution, and paleontology cannot be ignored. I argue here that the role of natural selection in contemporary evolutionary biology can be compared to that of Newtonian mechanics in contemporary physics: it can describe a given domain of observations, but it is insufficient to handle the different sources of evolutionary knowledge. Overemphasis on natural selection as the...
