    Geographical variation in sexual behavior and body traits in a sex role reversed wolf spider

    The Science of Nature 104(5-6) 40.

    Mating partners need to recognize, assess each other, and exchange information through behavioral events that occur before, during, and after mating. Sexual signals, as well as life history traits, are influenced by selective pressures and environmental factors that can vary across distant geographical areas. Allocosa senex is a sand-dwelling wolf spider which constructs burrows along the sandy coasts of Argentina, Brazil, and Uruguay. Females are the mobile sex that searches for males and initiates courtship. They prefer males which construct longer burrows, and males prefer virgin females in good body condition. The objective of this study was to compare sexual behavior patterns, as well as body characteristics and burrow dimensions, between two geographically distant locations of A. senex, one in Uruguay (Uruguayan location) and the other from central Argentina (Argentinean location). We found differences in the number of male abdominal vibrations, male and female touches during mating, and number of erections of male leg spines, which all were higher in matings of Argentinean pairs. On the other hand, male body mass and female body condition were higher in Uruguayan individuals. The wide distribution of A. senex could be determining variations in the biotic and abiotic features that affect the species, generating differences in the strength of selective forces acting on individuals from the two studied locations.

    Taxonomic revision of Peperomia (Piperaceae) from Uruguay

    Phytotaxa 244(2) 125.

    The genus Peperomia is represented by eight species in Uruguay: P. catharinae , P. comarapana , P. hispidula , P. increscens , P. pereskiifolia , P. psilostachya , P. tetraphylla and P. trineuroides . Peperomia psilostachya is reported for the first time for the flora of Uruguay, from material collected in moist hillside and riverside forests from the northeast and east of the country. Three new synonyms are proposed: P. arechavaletae var. arechavaletae as synonym of P. trineuroides , P. arechavaletae var. minor of P. tetraphylla and P. trapezoidalis of P. psilostachya . Lectotypes for P. arechavaletae, P. arechavaletae var. minor and P. tacuariana , and a neotype for P. herteri are designated. The taxonomic treatment includes synonymies used in Uruguay, morphological descriptions, distribution and habitat data, phenology, conservation assesment, observations, and material examined for each species treated. A species identification key, plant illustrations and distribution maps in Uruguay are provided.

    Threatened amphibians of Uruguay: Effectiveness of protected areas face of climate change

    Ecologia Austral 26(2) 138-149.

    Threatened amphibians of Uruguay: Effectiveness of protected areas face of climate change. Climate change (CC) constitutes one of the main biodiversity threats. The effects of CC on species are apparent worldwide, with primarily poleward and upward shifts in species distribution. Due to their narrow distribution, threatened species are highly vulnerable to CC. In this context, protected areas (PA) could be key tools for adaptation to CC. Our aims were to study the effects of CC on the distribution and richness of the threatened and near threatened amphibians of Uruguay; and to evaluate the effectiveness of the National Network of Protected Areas (NNPA) at present and under future climate scenarios. To model the distribution of nine species, we obtained records from herpetological collections, scientific publications and GBIF, as well as current data and future climate projections of the General Circulation Model HadCM3 under the A2 and B2 IPCC scenarios from Worldclim. To model species distribution we applied maximum entropy techniques (MAXENT). To evaluate the effectiveness of NNPA we conducted a gap analysis by overlaying PA with the distribution of species. The models indicate that the distribution of most amphibian species could expand in Uruguay in the future; except for Pleurodema bibroni y Melanophryniscus montevidensis. Local amphibian richness is predicted to increase, mainly in the northwest and east of the country. While amphibians studied are included in at least one PA, less than 2% of the distribution is actually covered by the NNPA, both currently and under CC scenarios; which it is a strong indicator of the inefficiency of the system. Although projected CC for this region would not constitute a major threat to amphibians studied, the scarce protection by the NNPA represents a risk to the conservation of herpetofauna facing the other components of global change .

    Global exchange and accumulation of non-native plants

    Nature 525(7567) 100-103.

    All around the globe, humans have greatly altered the abiotic and biotic environment with ever-increasing speed. One defining feature of the Anthropocene epoch1, 2 is the erosion of biogeographical barriers by human-mediated dispersal of species into new regions, where they can naturalize and cause ecological, economic and social damage3. So far, no comprehensive analysis of the global accumulation and exchange of alien plant species between continents has been performed, primarily because of a lack of data. Here we bridge this knowledge gap by using a unique global database on the occurrences of naturalized alien plant species in 481 mainland and 362 island regions. In total, 13,168 plant species, corresponding to 3.9% of the extant global vascular flora, or approximately the size of the native European flora, have become naturalized somewhere on the globe as a result of human activity. North America has accumulated the largest number of naturalized species, whereas the Pacific Islands show the fastest increase in species numbers with respect to their land area. Continents in the Northern Hemisphere have been the major donors of naturalized alien species to all other continents. Our results quantify for the first time the extent of plant naturalizations worldwide, and illustrate the urgent need for globally integrated efforts to control, manage and understand the spread of alien species.

    Phylogenetic relationships of species of Crenicichla (Teleostei: Cichlidae) from southern South America based on the mitochondrial cytochrome b gene

    Journal of Zoological Systematics and Evolutionary Research 48(3) 248-258.

    Abstract Phylogenetic analysis using Bayesian inference, likelihood and parsimony methods was conducted on 60 complete mitochondrial cytochrome b sequences from 21 species of Crenicichla, including all species known from Uruguay (Crenicichla celidochilus, Crenicichla lepidota Crenicichla minuano, Crenicichla missioneira, Crenicichla punctata, Crenicichla scottii, Crenicichla vittata), Crenicichla compressiceps, Crenicichla empheres, Crenicichla geayi, Crenicichla iguassuensis, Crenicichla macrophthalma, Crenicichla menezesi, Crenicichla notophthalmus, Crenicichla regani, Crenicichla cf. regani, Crenicichla semifasciata, Crenicichla sveni, Crenicichla tendybaguassu, two unidentified species, and also two species of Teleocichla. Bayesian analysis resulted in a trichotomy with three major groups: (1) The C. missioneira species group (C. celidochilus, C. empheres, C. minuano, C. missioneira, C. tendybaguassu, and an undescribed species analyzed); (2) a group of southern species (C. iguassuensis, C. punctata, C. scottii, C. vittata); and (3) a rather heterogeneous group comprising the type species C. macrophthalma, members of the Crenicichla reticulata species group (C. geayi, C. semifasciata), members of the Crenicichla wallacii species group (C. compressiceps, C. notophthalmus, C. regani, C. cf. regani), members of the Crenicichla saxatilis species group (C. lepidota, C. menezesi, C. sveni, C. sp.), and two species of Teleocichla. Parsimony jackknifing resulted in a quadritomy with: (1) C. macrophthalma, (2) Teleocichla, (3) the saxatilis + wallacii group species, and (4) the rest, which include C. geayi and C. semifasciata as sister group to a dichotomy with the C. missioneira group and the remaining southern species. The sequence variation within the C. missioneira group is remarkably minor despite considerable morphological differences, supporting the conclusion that it forms an endemic species flock in the Uruguay River basin. Previously proposed species groups within the speciose genus Crenicichla (more than 90 species known) are partly corroborated. However, C. celidochilus was not previously associated with the C. missioneira species group, and C. vittata has not previously been associated with C. scottii, C. iguassuensis, or C. punctata. Crenicichla lepidota, C. sveni, C. menezesi and C. sp. represent the C. saxatilis group. Species of small size, representing the C. wallacii species group and Teleocichla are characterized by very long branches, and the position of Teleocichla differed considerably between the Bayesian and parsimony trees. This finding does not invalidate Teleocichla but rather suggests that the several monophyletic major clades within Crenicichla may need nominal recognition. A putative hybrid specimen with a morphology combining components from C. vittata and C. scottii, but with a cytochrome b sequence from C. scottii was found in a sample from the Rio Quaraí/Cuareim. Another putative hybrid specimen with a unique morphology but a cytochrome b sequence agreeing with C. scottii was found in a sample from Maldonado, but no other Crenicichla species than C. scottii is known from that locality. Zusammenfassung Eine phylogenetische Analyse mit Hilfe von Bayesianischer Inferenz, Likelihood und Parsimonie-Methoden wurde an Hand von 60 kompletten mitochondrialen Cytochrome b-Sequenzen von 21 Arten von Crenicichla durchgeführt, die alle Arten aus Uruguay (C. celidochilus, C. lepidota C. minuano, C. missioneira, C. punctata, C. scottii, C. vittata,), außerdem C. compressiceps, C. empheres, C. geayi, C. iguassuensis, C. macrophthalma, C. menezesi, C. notophthalmus, C. regani, C. cf. regani, C. semifasciata, C. sveni, C. tendybaguassu, sowie zwei nicht identifizierte Arten und zwei Arten der Gattung Teleocichla umfassen. Die Bayesianische Analyse ergab eine Trichotomie mit drei Gruppen: (1) Die C. missioneira- Artengruppe (C. celidochilus, C. empheres, C. minuano, C. missioneira, C. tendybaguassu, und eine noch unbeschriebene Art; (2) eine Gruppe von im Süden verbreiteten Arten (C. iguassuensis, C. punctata, C. scottii, C. vittata), und (3) eine recht heterogene Gruppe, die die Typusart C. macrophthalma, Mitglieder der C. reticulata Artengruppe (C. geayi, C. semifasciata), Mitglieder der C. wallacii- Artengruppe (C. compressiceps, C. notophthalmus, C. regani, C. cf. regani), Mitglieder der C. saxatilis-Artengruppe (C. lepidota, C. menezesi, C. sveni, C. sp.), sowie die zwei Teleocichla-Arten beinhaltete. Die Parsimonie-Analyse mit Anwendung von Jackknifing erbrachte eine Quadritomie mit (1) C. macrophthalma, (2) Teleocichla, (3) den Arten der saxatilis + wallacii-Artengruppen, und (4) dem Rest, der C. geayi and C. semifasciata enthielt, die als Schwestergruppe zur C. missioneira-Artengruppe plus den übrigen im Süden verbreiteten Arten errechnet wurde. Die Variation in der DNA-Sequenz innerhalb der C. missioneira-Artengruppe ist erstaunlich niedrig trotz doch recht beträchtlicher morphologischer Unterschiede, was die Hypothese unterstützt, dass es sich um einen endemischen Artenschwarm des Uruguay-Flusses handelt. Crenicichla celidochilus war bisher nicht mit der C. missioneira-Artengruppe in Verbindung gebracht worden. Ebenso war man bisher nicht von einer näheren Verwandtschaft von Crenicichla vittata zu den Arten C. scottii, C. iguassuensis oder C. punctata ausgegangen. Bisher vorgeschlagene Artengruppen innerhalb der artenreichen Gattung Crenicichla (mit mehr als 90 Arten) wurden teilweise bestätigt. Crenicichla lepidota, C. sveni, C. menezesi und C. sp. gehören zur C. saxatilis-Artengruppe. Die kleinwüchsigen Arten, die die C. wallacii-Artengruppe repräsentieren, sowie auch Teleocichla waren durch lange Äste gekennzeichnet, wobei sich die Stellung von Teleocichla in den beiden Stammbäumen, die durch Bayesianische oder Parsimonie-Analysen erzielt wurden, stark unterschied. Dies heißt nicht, dass Teleocichla keine gültige Gattung darstellt, sondern dass mehrere monophyletische Gruppen innerhalb von Crenicichla einen wissenschaftlichen Namen bekommen sollten. Cytochrom b besitzt offenbar nicht das nötige Auflösungspotential, um die Verwandtschaftsverhältnisse zwischen den größeren Gruppen zu klären. Ein mögliches Hybridexemplar mit einer Mischung von morphologischen Merkmalen von C. vittata wie auch C. scottii, jedoch mit der Cytochrom b-Sequenz von C. scottii befand sich unter den Exemplaren, die im Rio Quaraí/Cuareim gesammelt worden waren. Ein weiteres mögliches Hybridtier mit einzigartigen morphologischen Merkmalen, aber einer Cytochrom b-Sequenz, die mit der von C. scottiiübereinstimmte, befand sich unter den Exemplaren von Maldonado, obwohl von dort bis auf C. scottii keine weitere Crenicichla-Art bekannt ist.
