The last stronghold of Muñoa’s Pampas cat (Leopardus munoai) in Argentina?
No full textThe Muñoa's Pampas cat (Leopardus munoai) is a relatively understudied species restricted to open savannas and grasslands of Southern Brazil, Uruguay and NE Argentina, that has been recently split from the broader “Pampas cat” species complex. Only three documented records of the species have been published since the year 2000 for the Argentine portion of its distribution, a situation that led to speculations regarding its conservation status in Argentina. We conducted an intensive camera-trap survey (2,067 camera-trapping stations and 15,560 camera-trapping days) to assess the presence of the Muñoa's Pampas cat in an area of 275.3 km2 within the Iberá National Park and the adjacent Iberá National Reserve, Corrientes province, Argentina. Four records of Muñoa's Pampas cat were obtained, representing at least two adults and one young individual. Only one camera-trapping record of this species had been previously obtained in Argentina, during a survey carried out in 2009 in the same study area, despite an important camera-trapping effort in the Corrientes province. All camera-trap records of Muñoa's Pampas cat in Argentina are concentrated in areas of temporally flooded grasslands locally known as “Malezales”, suggesting that this habitat type is critically important for the conservation of this rare felid. The Iberá National Park and the adjacent Iberá National Reserve provide the adequate framework for the conservation of an important piece of habitat for Muñoa's Pampas cat and constitute a stronghold for the species in Argentina.Fil: Distel, Augusto.

Software for continuum modeling of controls-structures interactions
No full textIt is clear that computer software is needed to assist in the generation of the equations of motion for complex, flexible spacecraft. Daniel Poelaert of ESTEC has developed the software DISTEL with which he has modeled the structural dynamics for different satellites. He is interested in expanding the capabilities of DISTEL to include structural damping and control systems. Unfortunately, the software has not been released. The author has developed similar software, PDEMOD, which has been used to model the Spacecraft control Laboratory Experiment (SCOLE), the Solar Array Flight Experiment (SAFE), the Mini-MAST truss, and the LACE satellite. PDEMOD has been used also for optimal parameter estimation and integrated control-structures design. PDEMOD is also being extended to include structural damping and control systems which are imbedded into the same equations for the structural dynamics. This paper will address the formulation of the equations for the structural dynamics of spacecraft structures which are constructed of a 3-dimensional arrangement of rigid bodies and flexible beam elements. Control system dynamics are imbedded into the same equations so that model order reduction approximations are not necessary. The input data consists of the physical data of the elements and the topological information describing how the elements are connected. PDEMOD accomplishes the following: (1) automatically assembles the equations of motion for the entire structural model; (2) calculates the modal frequencies; (3) calculates the mode shapes; (4) generates perspective views of the mode shapes; and (5) forms selected transfer functions. The software PDEMOD continues to be developed to provide additional features to assist in analyzing and synthesizing control and structural systems for flexible spacecraft

Coexistence of multiple proteobacterial endosymbionts in the gills of the wood-boring bivalve Lyrodus pedicellatus (Bivalvia: Teredinidae)

The definitive version was published in [citation], doi:10.1128/AEM.68.12.6292-6299.2002.Wood-boring bivalves of the family Teredinidae (commonly called shipworms) are known to harbor dense populations of gram-negative bacteria within specialized cells (bacteriocytes) in their gills. These symbionts are thought to provide enzymes, e.g., cellulase and dinitrogenase, which assist the host in utilizing wood as a primary food source. A cellulolytic, dinitrogen-fixing bacterium, Teredinibacter turnerae, has been isolated from the gill tissues of numerous teredinid bivalves and has been proposed to constitute the sole or predominant symbiont of this bivalve family. Here we demonstrate that one teredinid species, Lyrodus pedicellatus, contains at least four distinct bacterial 16S rRNA types within its gill bacteriocytes, one of which is identical to that of T. turnerae. Phylogenetic analyses indicate that the three newly detected ribotypes are derived from gamma proteobacteria that are related to but distinct (>6.5% sequence divergence) from T. turnerae. In situ hybridizations with 16S rRNA-directed probes demonstrated that the pattern of occurrence of symbiont ribotypes within bacteriocytes was predictable and specific, with some bacteriocytes containing two symbiont ribotypes. However, only two of the six possible pairwise combinations of the four ribotypes were observed to cooccur within the same host cells. The results presented here are consistent with the existence of a complex multiple symbiosis in this shipworm species.This work was supported by grants from the National Science Foundation

Resolution of Prochlorococcus and Synechococcus ecotypes by using 16S-23S ribosomal DNA internal transcribed spacer sequences
No full textAuthor Posting. © American Society for Microbiology, 2002. This article is posted here by permission of American Society for Microbiology for personal use, not for redistribution. The definitive version was published in Applied and Environmental Microbiology 68 (2002): 1180-1191, doi:10.1128/AEM.68.3.1180-1191.2002.Cultured isolates of the marine cyanobacteria Prochlorococcus and Synechococcus vary widely in their pigment compositions and growth responses to light and nutrients, yet show greater than 96% identity in their 16S ribosomal DNA (rDNA) sequences. In order to better define the genetic variation that accompanies their physiological diversity, sequences for the 16S-23S rDNA internal transcribed spacer (ITS) region were determined in 32 Prochlorococcus isolates and 25 Synechococcus isolates from around the globe. Each strain examined yielded one ITS sequence that contained two tRNA genes. Dramatic variations in the length and G+C content of the spacer were observed among the strains, particularly among Prochlorococcus strains. Secondary-structure models of the ITS were predicted in order to facilitate alignment of the sequences for phylogenetic analyses. The previously observed division of Prochlorococcus into two ecotypes (called high and low-B/A after their differences in chlorophyll content) were supported, as was the subdivision of the high-B/A ecotype into four genetically distinct clades. ITS-based phylogenies partitioned marine cluster A Synechococcus into six clades, three of which can be associated with a particular phenotype (motility, chromatic adaptation, and lack of phycourobilin). The pattern of sequence divergence within and between clades is suggestive of a mode of evolution driven by adaptive sweeps and implies that each clade represents an ecologically distinct population. Furthermore, many of the clades consist of strains isolated from disparate regions of the world's oceans, implying that they are geographically widely distributed. These results provide further evidence that natural populations of Prochlorococcus and Synechococcus consist of multiple coexisting ecotypes, genetically closely related but physiologically distinct, which may vary in relative abundance with changing environmental conditions.This work was supported by an NSF graduate fellowship to G.R., by

Teredinibacter turnerae gen. nov., sp. nov., a dinitrogen-fixing, cellulolytic, endosymbiotic c-proteobacterium isolated from the gills of wood-boring molluscs (Bivalvia: Teredinidae)
No full textAuthor Posting. © Society for General Mircobiology, 2002. This article is posted here by permission of Society for General Mircobiology for personal use, not for redistribution. The definitive version was published in International Journal of Systematic Bacteriology 52 (2002): 2261-2269, doi:10.1099/ijs.0.02184-0.A cellulolytic, dinitrogen-fixing bacterium isolated from the gill tissue of a
wood-boring mollusc (shipworm) Lyrodus pedicellatus of the bivalve family
Teredinidae and 58 additional strains with similar properties, isolated from
gills of 24 bivalve species representing 9 of 14 genera of Teredinidae, are
described. The cells are Gram-negative, rigid, rods (0<4–0<6x3–6 lm) that bear a
single polar flagellum. All isolates are capable of chemoheterotrophic growth
in a simple mineral medium supplemented with cellulose as a sole source of
carbon and energy. Xylan, pectin, carboxymethylcellulose, cellobiose and a
variety of sugars and organic acids also support growth. Growth requires
addition of combined nitrogen when cultures are vigorously aerated, but all
isolates fix dinitrogen under microaerobic conditions. The pH, temperature and
salinity optima for growth were determined for six isolates and are
approximately 8<5, 30–35 °C and 0<3 M NaCl respectively. The isolates are
marine. In addition to NaCl, growth requires elevated concentrations of Ca2M
and Mg2M that reflect the chemistry of seawater. The DNA GMC content ranged
from 49 to 51 mol%. Four isolates were identical with respect to small-subunit
rRNA sequence over 891 positions compared and fall within a unique clade in
the c-subclass of the Proteobacteria. Based on morphological, physiological
and phylogenetic characteristics and specific symbiotic association with
teredinid bivalves, a new genus and species, Teredinibacter turnerae gen. nov.,
sp. nov., is proposed. The type strain is T7902T (vATCC 39867TvDSM 15152T).This work was supported by grants from the National
