    Bromus tectorum invasion in South America: Patagonia under threat?

    (Journal name unavailable from Mendeley API. To be updated soon...)

    Bromus tectorum (cheatgrass) is an aggressive invasive species posing threats to native ecosystems including increase in fire frequency, alteration of water and nutrient cycles and exclusion of native species. As such, it is important to monitor this species worldwide. However, outside the United States, it has been poorly studied. We studied this species at two scales: (i) at a local scale, evaluating the species presence and its determinants, along the ecotonal area between the steppe and the forest within north-western Patagonia, to reveal whether B. tectorum is actually invading natural ecosystems in areas comparable with those invaded in USA, and (ii) at a regional scale, through a search of literature and herbaria databases on B. tectorum in South America, to determine the current known distribution of the species in this subcontinent. Results indicate that it is already invading north-western Patagonia in Argentina, mainly in the semi-arid part of the region, and that precipitation influences the invasion process. We found that for South America, B. tectorum has been only documented in southern Argentina and Chile. Given the similarities to other invaded regions, the possibility of invasion for Patagonia has been predicted but not prevented. It is important to study changes in the invasion level where it is already established, and to encourage managers with prevention and control strategies. Combining this information with lessons from places with extensive periods of invasion could help to initiate management of the species in areas where the invasion process is beginning and before the species spreads widely.

    Continuous and long-term monoxenic culture of the arbuscular mycorrhizal fungus Gigaspora decipiens in root organ culture

    (Journal name unavailable from Mendeley API. To be updated soon...)

    Establishment of arbuscular mycorrhizal (AM) germplasm collections is complex because of the obligate biotrophic nature of AM fungi. Only a few AM species are routinely maintained in monoxenic culture with Ri T-DNA transformed roots as host. Incorporation of new AM species into this culture system is important for molecular, physiological, and taxonomical studies. Here we report for the first time the successful monoxenic culture of Gigaspora decipiens (JA2 strain) with transformed carrot (Daucus carota) roots. In vitro cultures were established from field-collected spores; sub-culture of newly in vitro formed spores was established over five successive generations for a period of 6 y. Although initial culture of field-collected spores was difficult successive sub-cultures appeared to be adapted to the in vitro growing conditions. The JA2 strain of G. decipiens completed its life cycle while maintaining its morphological characteristics, stability, and propagule viability under the monoxenic conditions over several generations. This stable and homogeneous monoxenic material obtained for G. decipiens is part of the Banco de Glomeromycota In Vitro (BGIV, http://www.bgiv.com.ar), and could facilitate morphological, physiological, and molecular analysis of this AM species.

    Predicting the environmental niche of the genus Phymaturus: Are palluma and patagonicus groups ecologically differentiated?

    Austral Ecology 37(3) 392-400.

    The genus Phymaturus (Reptilia: Liolaemidae) is distributed in the mountains and rocky plateaux of Argentina and Chile and comprises two groups of species, palluma and patagonicus. The two lineages have diverged early in the evolution of the genus and up to today, there is very little geographical overlap between them. We worked with records of localities from the literature, herpetological collections and field data to evaluate habitat suitability of the genus Phymaturus. We used 11 environmental variables to develop environmental niche models (ENMs) for each group within the genus using the Maxent software, and to determine those variables that best explain the distribution of each group. We also estimated measures of niche similarity using ENMTools to determine whether niche differentiation is real or apparent. The geographical overlap between the groups was very low considering the large geographical range of the genus. Some variables, such as mean annual temperature, soil type and bare soil cover, have a high contribution to the models for both groups. The current niche overlap between Phymaturus groups indicates that the environmental niches of the palluma and patagonicus groups are not equivalent. Based on background analysis, we cannot reject the hypothesis that similarity (or divergence) between groups of Phymaturus is no more than expected based on the availability of habitat. The results of this study are a first approximation to the knowledge of the environmental variables associated with the palluma and patagonicus groups, and reveal that the ecological differences found between these groups are more likely due to habitat availability in their respective regions than to differences in habitat preferences.

    Situación Del Zorro Vinagre (Speothos Venaticus) En El Extremo Sur De Su Distribución (Argentina)

    (Journal name unavailable from Mendeley API. To be updated soon...)

    The fox vinegar (Speothos venaticus Lund, 1842) is a kind little known, threatened and difficult to detect. in the southern end of its range, Argentina, inhabiting an environment also highly threatened Atlantic forest interior. between methods available to predict the distribution geographical species, generalized linear models (GLM) provides results tailored to the actual distribution, although it requires reliable information on the locations where the species is absent. To better understand the distribution of S. venaticus, were georeferenced all known localities and a series of new records in Argentina, and modeled potential and actual distribution of the species, identifying variables that best explain their presence. to examine their conservation status, we analyzed the retraction of your area and its presence in protected areas in Argentina. were collected 182 georeferenced records (13 in Argentina). distribution predicted actual covers ~ 10.5 × 106km2, 57 and 73% of areas previously reported. The most significant variables were mean annual precipitation, precipitation of warmest quarter and annual temperature range. The dam with greater overlap in distribution was Cuniculus bale. after removal of Speothos habitats unsuitable for the surface distribution is reduced to 7.8 × 106km2, with two large patches probably connected in eastern Bolivia. in Argentina environmentally friendly area have dropped to 23.025km2 (80% of original), with four locations with records profoundly modified. Although most Protected areas could accommodate this species, only four have data (PN Iguazú, PP Urugua-t, PP Cross Knight Wedge and RPUM Valley Piru).

    Ecological Niche Modeling Meets Phylogeography to Unravel Hidden Past History of Key Forest Genera in Plant Geography: Podocarpus and Nothofagus

    (Journal name unavailable from Mendeley API. To be updated soon...)

    Phylogeographical methods and ecological niche modeling of cold-tolerant taxa, Podocarpus parlatorei a montane tropical conifer and Nothofagus pumilio inhabiting temperate areas of the southern Andes, were used as case studies to test if present populations are the result of local survival during cooling. Samples collected along their ranges were analyzed by nuclear isozymes and uniparentally inherited chloroplast DNA sequences. Modern and past last glacial maximum (LGM) ecological niche modeling (ENM) was developed using current climate data based on 19 bioclimatic variables and topography. Populations of the subtropical of P. parlatorei shared most haplotypes, southern populations were genetically distinct, and ENM yielded range expansion during the LGM. Latitudinally extreme populations of the temperate N. pumilio shared isozyme variants which was consistent with ENM showing suitable northern and southern areas. In contrast cpDNA yielded an ancient phylogeographic structure. Cold-hardy trees locally persisted along their ranges through ice periods without major range shifts in tropical and temperate regions.

    Shrinking forests under warming: evidence of Podocarpus parlatorei (pino del cerro) from the subtropical Andes.

    (Journal name unavailable from Mendeley API. To be updated soon...)

    Phylogeography in combination with ecological niche modeling (ENM) is a robust tool to analyze hypotheses on range shifts under changing climates particularly of taxa and areas with scant fossil records. We combined phylogeographic analysis and ENM techniques to study the effects of alternate cold and warm (i.e., glacial and interglacial) periods on the subtropical montane cold-tolerant conifer Podocarpus parlatorei from Yungas forests of the central Andes. Twenty-one populations, comprising 208 individuals, were analyzed by sequences of the trnL -trnF cpDNA region, and 78 sites were included in the ENM. Eight haplotypes were detected, most of which were widespread while 3 of them were exclusive of latitudinally marginal areas. Haplotype diversity was mostly even throughout the latitudinal range. Two distribution models based on 8 bioclimatic variables indicate a rather continuous distribution during cooling, while under warming remained within stable, yet increasingly fragmented, areas. Although no major range shifts are expected with warming, long-lasting persistence of cold-hardy taxa inhabiting subtropical mountains may include in situ and ex situ conservation actions particularly toward southern (colder) areas.

    Licofitas (Equisetopsida : Lycopodiidae) de las Sierras Centrales de Argentina : un enfoque panbiogeográfico

    (Journal name unavailable from Mendeley API. To be updated soon...)

    Lycophytes (Equisetopsida: Lycopodiidae) from the Central Hills of Argentina: a panbiogeographic approach. Lycophytes are the most ancient lineage of vascular plants and include Lycopodiaceae, Isoëtaceae and Selaginellaceae. They are a monophyletic group separated from ferns and seed plants and are especially useful for establishing biogeographic patterns, due to their lack of coevolutionary relationships with biotic vectors, their monophyly and their remarkable morphological conservatism. The individual tracks of the seven taxa of lycophytes from central Argentina were drawn and the generalized track obtained shows that the central hills of Argentina are the austral extreme of the distribution of a Neotropical biotic component, with closer relationships with the Subandean hills and the Bolivian and Peruvian Andes than to the Chaco (where they are included), bordering the South American Transition Zone. The latter is characterized by arid environments and is a successful barrier for Lycophytes, separating the austral region of Argentina and Chile from the other parts of South America.

    Lizards as conservation targets in Argentinean Patagonia

    (Journal name unavailable from Mendeley API. To be updated soon...)

    Patagonia is considered a region of high conservation priority due to its outstanding and representative habitats and high endemism. The purpose of this study is to assess the degree of representation of Patagonian lizards in the existing protected area network, and to identify conservation priority areas that may help expand the current system. We obtained locality data for all Patagonian species from different sources and used them, together with environmental variables, to model their potential distribution. We then used a reserve-selection algorithm to assess the performance of the existing protected area network in representing all lizard species, and to identify new priority areas. Our results indicate that the existing protected areas fail to protect 10 of the 60 species modeled. To protect at least 5% of the geographic distribution of all species, the existing reserve network would need an additional 3.7% of the study area, whereas to protect at least 10% of the distribution of species, an extra 9.9% would be needed. We found eleven main priority areas needed to protect at least 5% or 10% of the distribution of all species of lizards. In conclusion, the current reserve network is not very effective at protecting the lizards of Patagonia, particularly those species with range-restricted distributions. We hope that this contribution will help direct conservation efforts in the region, by maximising the protection of biodiversity.

    Distribución geográfica y patrones de movimiento de la monterita canela (Poospiza ornata) y el yal carbonero (Phrygilus carbonarius) en Argentina

    (Journal name unavailable from Mendeley API. To be updated soon...)

    To estab- lish the geographic distribution of a species it is necessary to ascertain the places where the species is likely to occur. However, it requires verifying whether its populations are sedentary, migratory, transient, or casual. In this study, we analyze the geographic distribution of two endemic emberizids in Argentina, the Cinnamon Warbling-Finch (Poospiza ornata) and the Carbonated Sierra-Finch (Phrygilus carbona- rius). To study the residence status of the populations and movement patterns of these species we com- bine geographic information about the occurrence of the species with local information about abundance and mark-recapture studies in the central Monte desert. Analysis at biogeographic scale showed that both species mainly occur in arid and semi-arid environments of Argentina. The Cinnamon Warbling- Finch shows movements that correspond to short-distance migration. In contrast, movement patterns of the Carbonated Sierra-Finch are not so clear because the species is always present in its central distri- butional range. At local scale, in the central Monte desert, seasonal changes in abundance were consis- tent with the observed patterns in the geographic distribution and movement of both species. Banding of birds also showed that these species are highly mobile, at least in this region. Local results are consis- tent with the hypotheses that the Cinnamon Warbling-Finch is a nomadic species in its breeding range while the Carbonated Sierra-Finch exhibits temporal changes in the boundary of its southern breeding range. The combined analysis at different spatial scales allowed us to describe the movement patterns of Cinnamon Warbling-Finch and Carbonated Sierra-Finch. Also, it highlights the importance of having an accurate description of the seasonal geographic distribution of birds.
