Abstract

Bacterias aisladas de las branquias del ostión japonés Crassostrea gigas, cultivado en Bahía Falsa, Baja California, México

REBECA VÁSQUEZ-YEOMANS, JORGE CÁCERES-MARTÍNEZ, ADRIÁN MAURICIO GARCÍA ORTEGA

SINCE THE LATE 70S, THE JAPANESE OYSTER, CRASSOSTREA GIGAS, HAS BEEN CULTURED IN BAHÍA FALSA, BAJA CALIFORNIA, MEXICO. NOWADAYS, THERE ARE 21 CULTURE COMPANIES INVOLVED IN THIS ACTIVITY. IN 1998, UNUSUAL MORTALITY EPISODES OF OYSTERS BEGAN TO OCCUR, REACHING UP TO 80% OF THE PRODUCTION. THESE MORTALITYÂ EPISODES HAVE BEEN RECURRED UP TO DATE AND, THE HYPOTHESIS OF A POSSIBLE PATHOGEN INVOLVED, SUCH AS A VIRUS, BACTERIA OR BOTH, REMAINS OPEN. THIS WORK SHOWS THE RESULTS OF A STUDY ON THE PHYSIOLOGICAL AND BIOCHEMICAL CHARACTERIZATION OF ISOLATED BACTERIA FROM GILL TISSUE OF OYSTERS RECOLLECTED DURING A MORTALITY EPISODE IN 2001. THREE COLONIES WERE ISOLATED, TWO OF THEM GREW IN TCBS SELECTIVE MEDIUM, FORMING YELLOW COLONIES, WHICH WERE IDENTIFIED AS BELONGING TO THE GENUS AEROMONAS. THE THIRD COLONY COULD NOT BE CULTURED OR IDENTIFIED. THERE ARE NOT RECORDS ON THE PATHOGENICITY OF AEROMONAS SPP. IN MOLLUSKS; HOWEVER, THEY HAVE BEEN REPORTED AS PATHOGENIC FOR FISHES AND REPTILES. IDENTIFICATION OF THE NOT CULTURED BACTERIA MUST BE CARRY OUT BY MOLECULAR METHODS.

Descripción de una especie nueva de Tylodelphys (Digenea:Diplostomidae) parásita de Podiceps major (Aves:Podicepediae) de Argentina

LÍA I. LUNASCHI, FABIANA B. DRAGO

A NEW SPECIES OF DIPLOSTOMID, TYLODELPHYS ADULTA SP. NOV. (DIGENEA: DIPLOSTOMIDAE), IS DESCRIBED ON THE BASIS OF ADULT SPECIMENS FOUND IN THE INTESTINE OF NATURALLY INFECTED GREAT GREBES, PODICEPS MAJOR (BODDAERT), FROM LACOMBE LAGOON, BUENOS AIRES PROVINCE, ARGENTINA. THIS NEW SPECIES IS DESCRIBED ON THE BASIS OF ADULT SPECIMENS IN THE INTESTINE OF NATURALLY INFECTED GREAT GREBES, PODICEPS MAJOR (BODDAERT), FROM LACOMBE LAGOON, BUENOS AIRES PROVINCE, ARGENTINA. THIS NEW SPECIES IS PLACED IN THE GENUS TYLODELPHYS BECAUSE IT PRESENTS INDISTINCTLY BIPARTITE BODY, WELL DEVELOPED VENTRAL SUCKER AND PSEUDOSUCKERS, CONICAL POSTERIOR SEGMENT, TESTIS IN TANDEM, SYMMETRICAL, SMALL GENITAL CONE AND THE VITELLINE GLANDS DISTRIBUTED IN BOTH SEGMENTS. TYLODELPHYS ADULTA SP. NOV. IS CHARACTERIZED BY HAVING THE ANTERIOR SEGMENT DORSALLY AND VENTRALLY COVERED BY FINE SPINES UP TO THE HOLDFAST ORGAN PROXIMITY, THE VITELLINE GLANDS DISTRIBUTED FROM THE VENTRAL SUCKER AND A LARGE GENITAL PORE IN TERMINAL POSITION. TYLODELPHYS ADULTA SP. NOV. MAINLY DIFFERS FROM THE KNOWN NEOTROPICAL SPECIES T. AMERICANA AND T. ELONGATA BY THE RESTRICTED DISTRIBUTION OF THE VITELLINE GLANDS AND THE LARGER SIZE OF THE PSEUDOSUCKERS. THIS IS THE FIRST RECORD OF ADULT SPECIMENS OF THE GENUS TYLODELPHYS FROM ARGENTINA.

DONATELLA FODDAI, LUIS ALBERTO PEREIRA, ALESSANDRO MINELLI

A CATALOGUE OF THE CHILOPODA GEOPHILOMORPHA KNOWN FROM BRAZILIAN AMAZONIA IS HERE PRESENTED. THIRTY-ONE SPECIES ARE KNOWN FROM THIS REGION; ALL BUT SIX OF THESE SPECIES ARE ENDEMIC TO IT, AS IS ONE (HYPHYDROPHILUS) OF THE ELEVEN GENERA HITHERTO KNOWN FROM AMAZONIA.

Arañas de humedales del sur de Baja California, México

JORGE LLINAS-GUTIÉRREZ, MARÍA LUISA JIMÉNEZ

DURING THE AUTUMNS OF 1994 TO 1996, 355 ADULT SPECIMENS BELONGING TO 61 SPECIES OF SPIDERS WERE COLLECTED FROM FIVE WETLANDS AND ONE INTERMITTENT SPRING IN SOUTHERN BAJA CALIFORNIA. WANDERING SPIDERS WERE DOMINANT, WITH 36 SPECIES AND 63% OF TOTAL ABUNDANCE. DIFFERENCES IN FLORISTIC RICHNESS BETWEEN SITES ALSO WERE RELATED TO VARIATIONS IN THE ARACHNOFAUNA. MISUMENOPS DUBIUS, HIBANA INCURSA, AND THERIDION SP. WERE MORE ABUNDANT, AND WITH THE EXCEPTION OF THE LAST SPECIES, THEY ARE ALSO MORE COMMON IN ASSOCIATION WITH DICTYNA SP. AND THIODINA SYLVANA, WHICH WERE LESS ABUNDANT. THE OASIS OF SAN IGNACIO AND THE SPRING AT SAN BARTOLO WERE THE SITES WITH MOST SPECIES RICHNESS AND HETEROGENEITY, WITH SPECIFIC DIVERSITY OF 3.22 AND 2.63, RESPECTIVELY. ABOUT 59% OF THE SPECIES WERE EXCLUSIVE IN EACH LOCALITY AND THE MEAN SIMILARITY BETWEEN THEM WAS 0.27; 0.53 SIMILARITY BETWEEN BOCA DE LA SIERRA POOLS AND SAN BARTOLO SPRING, AND 0.46 BETWEEN SAN BARTOLO SPRING AND THE INTERMITTENT SAN JUAN BAUTISTA SPRING. INTENSIVE AND SEASONAL SAMPLINGS, AND MORE EFFECTIVE COLLECTING METHODS COULD PROVIDE MORE ACCURATE CHARACTERISTICS OF THE ARACHNOFAUNA IN THE SOUTHERN PART OF THE PENINSULA.

DIFFERENCES WITH OTHER MEMBERS OF THE "LATIPES" SPECIES GROUP ARE OUTLINED. DRAWINGS OF DIAGNOSTIC STRUCTURES OF THE NEW SPECIES, AND A KEY TO THE SPECIES OF THE SUBGENUS CHLAENOBIA KNOWN FROM MORAZAN AND PARAISO ARE INCLUDED.

Variación anual en la actividad de anidación y productividad de la cotorra serrana occidental (Rhynchopsitta pachyrhyncha)

TIBERIO CÉSAR MONTERRUBIO-RICO, ERNESTO ENKERLIN-HOEFLICH

WE STUDIED ANNUAL VARIATION IN REPRODUCTIVE ACTIVITY AND PRODUCTIVITY OF THE THICK-BILLED PARROT (RHYNCHOPSITTA PACHYRHYNCHA) DURING A FIVE YEAR PERIOD (1997-2001), IN FIVE NESTING AREAS AT THE SIERRA MADRE OCCIDENTAL IN MEXICO. TWO BREEDING AREAS CONTINUE TO BE THE BREEDING STRONGHOLDS FOR THE SPECIES. WE DOCUMENTED 491 NESTING PAIRS AND DETERMINED THE OUTCOME OF 162 ACCESSIBLE NESTS. A NESTING PAIR LAID IN AVERAGE 2.7 EGGS, AND PRODUCED 1.6 FLEDLINGS PER EGG-LAYING PAIR. OVERALL NEST SUCCESS WAS 80% AND NOT SIGNIFICATIVE DIFFERENCES WERE OBSERVED IN NESTING SUCCESS AND PRODUCTIVITY AMONG AREAS WITH DIFFERENT CONSERVATION CONDITIONS AND FORESTRY MANAGEMENT REGIMES. HOWEVER, THE BESTPRESERVED NESTING AREAS CONCENTRATED A HIGH NUMBER OF NESTS. SOME YEARS THE SPECIES BREEDING ACTIVITY DECLINES DRASTICALLY AT REGIONAL SCALE AFFECTING SEVERAL NESTING AREAS.

Composición de la dieta de la codorniz Moctezuma (Cyrtonix montezumae) en el noroeste del Estado de México

COMPOSITION OF THE MONTEZUMA QUAIL'S DIET WAS STUDIED IN NORTHWEST STATE OF MEXICO. NINE ESOPHAGEAL CONTENTS WERE COLLECTED DURING THE WINTER HUNTING SEASON 2001-2002. MACROHISTOLOGICAL ANALYSES INDICATE THAT THE MAIN FOOD ITEM WAS OXALIS SPP. BULB (41.99% OF DRY MATTER), FOLLOWED BY WHEAT GRAIN (40.97%), CHENOPODIUM SP. SEEDS (16.46%), OAT SEEDS (0.54%) AND INSECTS (0.015%). NUTRIENT CONCENTRATION ESTIMATED WAS 15.30% CRUDE PROTEIN, 0.19% CA, 0.32% P AND 3.169 KCAL OF METABOLIZABLE ENERGY PER G OF DRY MATTER. THE RESULTS INDICATE THAT OXALIS BULBS AND WHEAT GRAIN ARE THE MAIN ENERGETIC FOOD ITEMS DURING THE WINTER.

Análisis mastofaunístico de la Zona Sujeta a Conservación Ecológica, Laguna Bélgica, Chiapas, México

ALEJANDRA RIECHERS PÉREZ

DERIVED FROM THREE FIELD TRIPS AND THE ANALYSIS OF THE INFORMATION OF FOUR SCIENTIFIC COLLECTIONS, I PRESENT THE LIST OF MAMMAL SPECIES FROM "ZONA SUJETA A CONSERVACIÓN ECOLÓGICA LAGUNA BÉLGICA" (A NATURAL PROTECTED AREA), LOCATED IN OCOZOCOAUTLA, CHIAPAS. AN ANALYSIS OF SIMILARITY WAS CONDUCTED, CONSIDERING FOUR NATURAL PROTECTED AREAS IN CHIAPAS (PARQUE NACIONAL CAÑÓN DEL SUMIDERO, RESERVA DE LA BIOSFERA MONTES AZULES, RESERVA DE LA BIOSFERA SELVA EL OCOTE AND RESERVA DE LA BIOSFERA EL TRIUNFO) AND ONE WITHOUT PROTECTION (COAPILLA). THE MAMMALS RECORDED REPRESENT SEVEN ORDERS, 18 FAMILIES, 44 GENERA AND 56 SPECIES. NINE SPECIES ARE UNDER SOME CATEGORY OF PROTECTION (CALUROMYS DERBIANUS, MICRONYCTERIS BRACHYOTIS, TRACHOPS CIRRHOSUS, LONCHORINA AURITA, MIMON BENETTII, BASSARISCUS SUMICHRASTI, COENDOU MEXICANUS, TAMANDUA MEXICANA Y LEOPARDUS PARDALIS) IN AGREEMENT WITH MEXICAN REGULATION (NOM-059-ECOL-2001). THE VALUES OF FAUNISTIC SIMILARITY OF THE COMPARED LOCALITIES WERE ABOVE 71%. EL OCOTE AND LAGUNA BÉLGICA WERE MOST SIMILAR (92.9%).

Inventario biológico preliminar de Cerro Piedra Larga, Oaxaca, México: aves, mamíferos,reptiles anfibios y plantas

CERRO PIEDRA LARGA IS AN ISOLATED MOUNTAIN MASSIF IN EASTERN OAXACA, LYING JUST WEST OF THE ISTHMUS OF TEHUANTEPEC. NO PREVIOUS BIOLOGICAL INVENTORIES HAD ASSESSED THIS RANGE, MAKING EVEN A PRELIMINARY ASSESSMENT OF INTEREST. DURING SEVERAL WEEKS OF WORK IN THE HIGHER PORTIONS OF THE MOUNTAIN RANGE, WE ASSEMBLED SUCH PRELIMINARY INVENTORIES FOR BIRDS, MAMMALS, REPTILES, AMPHIBIANS, AND PLANTS. GEOGRAPHICALLY, THE AFFINITIES OF THE HIGHLAND BIOTA OF CERRO PIEDRA LARGA APPEAR TO BE MIXED BETWEEN THE SIERRA MADRE ORIENTAL AND THE SIERRA MADRE DEL SUR, SUGGESTING THAT THE BIOTA LIKELY ORIGINATED BY COLONIZATION, RATHER THAN VIA HISTORICAL CONNECTIONS.
