    Environmental predictors of habitat suitability and biogeographical range of Franciscana dolphins (Pontoporia blainvillei)

    Global Ecology and Conservation 3 90-99.

    The aim of this study was to use species distribution models to estimate the effects of environmental variables on the habitat suitability of river dolphins Pontoporia blainvillei (franciscanas) along their overall biogeographical distribution. Based on the literature, we selected six environmental variables to be included in the models; four climatic factors (surface sea temperature, salinity, turbidity and productivity) and two biotic factors (prey availability and fishing effort). We determined that the biographic range is under the following limits: temperature less than 19°C, a salinity of 36 psu and a minimal probability of the occurrence of fish C. guatucupa of 0.297. In the discussion, we postulate hypotheses on the behavioural and physiological mechanisms that cause these associations between environmental predictors and Franciscanas distribution. There was a good fit between the distribution predicted by the species distribution model and the one proposed by the experts of the International Union for Conservation of Nature; however, our analysis failed to highlight the fundamental role of bycatch as the main threat to this dolphin species.

    Estimating the geographic range of a threatened shark in a data-poor region: Cetorhinus maximus in the South Atlantic Ocean

    Advancing biodiversity science 61.

    The distribution of the pla nktivorous basking shark, Cetorhinus maximus , is influenced by zooplankton abundance at small scales and temperature at medium scales in the North Atlantic. Here, we estimate the distribution of basking sharks on South Atlantic continental shelves, and the relative importance of chlorophyll concentration, as a proxy for zooplankton abundance, and temperature in det ermining habitat suitability for basking sharks at large scales. We us ed maximum entropy (MaxEnt) and maximum likelihood (MaxLike) speci es distribution modelling to test three hypotheses: the distribution of basking sharks is determined by (1) temperature, (2) chlor ophyll concentration, or (3) both chlorophyll and temperature, while c onsidering other factors, such as oxygen and salinity. Off South America, basking shark habitat included subtropical, temperate and cool-temperate waters between approximately 20 o S and 55 o S. Off Africa, basking shark habitat was limited to cool-temperate waters off Namibia an d southern South Africa. MaxLik e models had a better fit than MaxEnt models. The best model included minimum chlorophyll concentration, dissolved oxygen concentration, and sea surface temperature range, supporting hypothesis 3. However, of all variables included in th e best model, minimum chlorophyll concentration had the highes t influence on basking shark distribution. Unlike the Nort h Atlantic distribution, the South Atlan tic distribution of basking sharks includ es subtropical and cool-temperate waters. This difference is explained by high minimum chlorophyll concentration off southern Brazil as compar ed to North Atlantic subtropical areas. Observati ons in other regions of the world support this conclusion. The highest habitat suita bility for basking sharks is located close to nearshore areas that experience high anthropogenic impact

    Phylogeny and biogeography of Asthenopodinae with a revision of Asthenopus, reinstatement of Asthenopodes, and the description of the new genera Hubbardipes and Priasthenopus (Ephemeroptera, Polymitarcyidae).

    ZooKeys(478) 45-128.

    The Neotropical species of Asthenopodinae are revised in a formal phylogenetic context. The five known species of Asthenopus Eaton, 1871, together with other five new species were included in a cladistic analysis using morphological characters (continuous and discretes). Representatives of the Afro-Oriental group of the subfamily (Povilla Navás, 1912 and Languidipes Hubbard, 1984) were also included to test the monophyletic hypothesis traditionally accepted for the group. Additional taxa representing the other subfamilies of Polymitarcyidae were incorparated: Ephoron Williamson, 1802 (Polymitarcyinae) and Campsurus Eaton, 1868, Tortopus Needham & Murphy, 1924 and Tortopsis Molineri, 2010 (Campsurinae). A matrix of 17 taxa and 72 characters was analyzed under parsimony resulting in a single tree supporting the monophyly of the subfamily Asthenopodinae. Other results include the monophyly of the Afro-Oriental taxa (Povilla and Languidipes), the paraphyletic nature of Neotropical Asthenopodinae, and the recognition of four South American genera: Asthenopus (including Asthenopuscurtus (Hagen), 1861, Asthenopusangelae de Souza & Molineri, 2012, Asthenopusmagnus sp. n., Asthenopushubbardi sp. n., Asthenopusguarani sp. n.), Asthenopodes Ulmer, 1924, stat. n. (including Asthenopuspicteti Hubbard, 1975, stat. n., Asthenopodestraverae sp. n., Asthenopodeschumuco sp. n.), Priasthenopus gen. n. (including Priasthenopusgilliesi (Domínguez), 1988, comb. n.), and Hubbardipes gen. n. (including Hubbardipescrenulatus (Molineri et al.), 2011, comb. n.). Descriptions, diagnoses, illustrations and keys are presented for all Neotropical taxa of Asthenopodinae (adults of both sexes, eggs and nymphs). Additionally a key to the subfamilies and genera of Polymitarcyidae is included. A quantitative biogeographic analysis of vicariance is presented and discussed through the study of the "taxon history" of the group. Abstract available from the publisher.

    Historical and ecological divergence among populations of Monttea chilensis (Plantaginaceae), an endemic endangered shrub bordering the Atacama Desert, Chile

    Evolutionary Ecology 28(4) 751-774.

    The coastal deserts of northern Chile show an important latitudinal gradient of aridity with more arid areas to the north of the Atacama Desert than to the south. Several plant species have disjunct distributions that correspond with the extremes of this latitudinal gradient. In this study, using genetic (chloroplast and nuclear DNA), morphological (vegetative and floral traits of various kinds) and climatic and topographic information, we explored ecological and historical events that have putatively shaped patterns of variation among Monttea chilensis populations—a species that shows this disjunct distribution. Through phylogeographic and phylogenetic analyses, two divergent lineages were identified located at the latitudinal extremes. The lineage located northern lineage (NG) of the Atacama Desert showed more genetic diversity and better-resolved phylogeographic structure than the southern lineage (SG). Considerable morphological variation across the geographical range corresponds with these genetic groups. We observed contrasting relationships between floral and vegetative traits: populations from the most arid region NG possessed larger flowers, but smaller vegetative values, and vice versa. Niche modelling and multivariate analyses, including environmental data, revealed different environmental requirements for each lineage. NG plants occur in regions with warmer and drier climatic conditions and at higher altitudes, while SG populations inhabit colder and more humid environments and lower altitudes. The evolutionary history of M. chilensis exhibits a phylogeographical footprint consistent with past fragmentation and allopatric differentiation, where the hyper-arid zone formed by the Atacama Desert clearly acted as an important gene flow barrier. This barrier has led to considerable differentiation in morphology and ecology, resulting in two ecotypes or geographical races, suggesting incipient speciation promoted by local adaptation and geographical isolation.

    A maximum entropy model for predicting wild boar distribution in Spain

    Spanish Journal of Agricultural Research 12(4) 984.

    Wild boar (Sus scrofa) populations in many areas of the Palearctic including the Iberian Peninsula have grown continuously over the last century. This increase has led to numerous different types of conflicts due to the damage these mammals can cause to agriculture, the problems they create in the conservation of natural areas, and the threat they pose to animal health. In the context of both wildlife management and the design of health programs for disease control, it is essential to know how wild boar are distributed on a large spatial scale. Given that the quantifying of the distribution of wild species using census techniques is virtually impossible in the case of large-scale studies, modeling techniques have thus to be used instead to estimate animals’ distributions, densities, and abundances. In this study, the potential distribution of wild boar in Spain was predicted by integrating data of presence and environmental variables into a MaxEnt approach. We built and tested models using 100 bootstrapped replicates. For each replicate or simulation, presence data was divided into two subsets that were used for model fitting (60% of the data) and cross-validation (40% of the data). The final model was found to be accurate with an area under the receiver operating characteristic curve (AUC) value of 0.79. Six explanatory variables for predicting wild boar distribution were identified on the basis of the percentage of their contribution to the model. The model exhibited a high degree of predictive accuracy, which has been confirmed by its agreement with satellite images and field surveys.

    Successful Biological Control of Tropical Soda Apple (Solanales: Solanaceae) in Florida: A Review of Key Program Components

    Florida Entomologist 97(1) 179-190.

    Tropical soda apple (Solanum viarum Dunal) (Solanaceae) is a small shrub native to South America that is invasive in pastures and conservation areas across Florida. Dense patches of tropical soda apple not only reduce cattle stocking rates and limit their movement, but also serve as reservoirs for pests of solanaceous crops. A classical biological control program was initiated in 1994 with exploration for natural enemies of tropical soda apple in Argentina, Brazil, and Paraguay. Host specificity tests conducted under laboratory and field conditions demonstrated that the leaf feeding beetle Gratiana boliviana Dunal (Coleoptera: Chrysome- lidae) was a specialist herbivore that completes development only on the target weed. After obtaining appropriate permits, field releases of G. boliviana were initiated in Florida in May of 2003. Larvae and adults of G. boliviana feed on tropical soda apple leaves and may com- pletely defoliate their host plants, resulting in reduced growth and fruit production. Mass rearing facilities for the beetle were established in northern, central and southern Florida, and adults were either hand-carried or transported to release sites by overnight courier. From 2003 to 2011, a total of 250,723 beetles were released and they became established throughout Florida, however, their impact is more noticeable in regions below latitude 29 °N. Reductions of tropical soda apple densities caused by damage by the beetle were vis- ible 2-3 yr after initial release, or in some cases, within a few months. Various methods of technology transfer were used to inform the public, land owners, funding agencies and scientists about the biological control program, including articles in trade magazines, exten- sion publications, websites, videos, field days and scientific publications. The project was successful because of the coordinated efforts of personnel from federal, state and county agencies. Key

    Carnivorans at the Great American Biotic Interchange: new discoveries from the northern neotropics

    Die Naturwissenschaften(2011).

    We report two fossil procyonids, Cyonasua sp. and Chapalmalania sp., from the late Pliocene of Venezuela (Vergel Member, San Gregorio Formation) and Colombia (Ware Formation), respectively. The occurrence of these pre-Holocene procyonids outside Argentina and in the north of South America provides further information about the Great American Biotic Interchange (GABI). The new specimens are recognized in the same monophyletic group as procyonids found in the southern part of the continent, the "Cyonasua group," formed by species of Cyonasua and Chapalmalania. The phylogenetic analysis that includes the two new findings support the view that procyonids dispersed from North America in two separate events (initially, previous to the first major migration wave-GABI 1-and then within the last major migration wave-GABI 4-). This involved reciprocal lineage migrations from North to South America, and included the evolution of South American endemic forms.

    Multi-symbiotic systems: functional implications of the coexistence of grass-endophyte and legume-rhizobia symbioses

    Oikos Forthcoming.

    The coexistence of symbionts with different functional roles in co-occurring plants is highly probable in terrestrial ecosystems. Analyses of how plants and microbes interact above- and belowground in multi-symbiotic systems are key to understanding community structure and ecosystem functioning. We performed an outdoor experiment in mesocosms to investigate the consequences of the interaction of a provider belowground symbiont of legumes (nitrogen-fixing bacteria) and a protector aerial fungal symbiont of grasses ( Epichlo ë endophyte) on nitrogen dynamics and aboveground net primary productivity. Four plants of Trifolium repens (Trifolium, a perennial legume) either inoculated or not with Rhizobium legu-minosarum, grew surrounded by 16 plants of Lolium multiflorum (Lolium, an annual grass), with either low or high levels of the endophyte Neotyphodium occultans. After five months, we quantified the number of nodules in Trifolium roots, shoot biomass of both plant species, and the contribution of atmospheric nitrogen fixation vs. soil nitrogen uptake to above- ground nitrogen in each plant species. The endophyte increased grass biomass production ( ? 16%), and nitrogen uptake from the soil – the main source for the grass. Further, it reduced the nodulation of neighbour Trifolium plants (50%). Notably, due to a compensatory increase in nitrogen fixation per nodule, this reduced neither its atmospheric nitrogen fixation – the main source of nitrogen for the legume – nor its biomass production, both of which were doubled by rhizobial inoculation. In consequence, the total amount of nitrogen in aboveground biomass and aboveground productivity were greatest in mesocosms with both symbionts (i.e. high rhizobia high endophyte). These results show that, in spite of the deleterious effect of the endophyte on the establishment of the rhizobia – legume symbiosis, the coexistence of these symbionts, leading to additive eff ects on nitrogen capture and aboveground productivity, can generate complementarity on the functioning of multi-symbiotic systems.
