    Quantifying and mapping ecosystem services: Demand and supply of pollination in the European Union

    Ecological Indicators 36 131-141.

    Biotic pollination is an important ecosystem service for the production of many food crops. The supply of pollination is mostly studied at the landscape scale while recent studies on the demand for pollination services provide a global-scale picture based on aggregate national-level data. This paper quantifies both demand and supply of pollination in the European Union (EU) at a relatively high spatial resolution, allowing an analysis of the match between demand and supply. Finally, we evaluate how policies interact with the spatial differences between demand and supply of this ecosystem service. We mapped the crop area requiring pollination for optimal production (demand) and both bee habitat and related visitation probability (supply) using detailed agricultural and landscape data. We compared the maps of demand and supply by visual comparison, descriptive statics and a trend surface generalized additive model to analyze the relation between visitation probability and the presence or absence of pollinator dependent crops. A sensitivity analysis was done to test the robustness of the pollination supply model. Finally, the impact of EU Biodiversity Strategy and Biofuel Directive were evaluated by identifying areas where these policies would influence the demand or supply of pollination. In the EU, 12% of the total cropland area was dependent on pollinators for optimal agricultural produc- tion. Pollinator habitat is especially abundant in mosaic landscapes as found in hilly and mountainous areas. Although covering less than 0.5% of the agricultural area, the presence of green linear elements increased the visitation probability by 5–20% while being the sole providers of pollinators in 12% of the croplands. In half of the area with a high pollination demand, the supply of pollination is also high. Irre- spective of the different parameterizations, total habitat areas and visitation probability were highest in croplands without pollinator dependent crops and lowest in hotspots of pollination demand. The analysis of the match between pollination supply and demand for this service indicates that for improving or ensuring pollination one must consider both the demand and supply of the process of crop pollination for optimal results.

    Integrating Open Access Geospatial Data to Map the Habitat Suitability of the Declining Corn Bunting (Miliaria calandra)

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

    The efficacy of integrating open access geospatial data to produce habitat suitability maps for the corn bunting (Miliaria calandra) was investigated. Landsat Enhanced Thematic Mapper Plus (ETM+), Shuttle Radar Topography Mission (SRTM) and Corine (Coordination of Information on the Environment) land cover data for the year 2000 (CLC2000) were processed to extract explanatory variables and divided into three sets; Satellite (ETM+, SRTM), CLC2000 and Combined (CLC2000 + Satellite). Presence-absence data for M. calandra, collected during structured surveys for the Catalan Breeding Bird Atlas, were provided by the Catalan Ornithological Institute. The dataset was partitioned into an equal number of presence and absence points by dividing it into five groups, each composed of 88 randomly selected presence points to match the number of absences. A logistic regression model was then built for each group. Models were evaluated using area under the curve (AUC) of the receiver operating characteristic (ROC). Results of the five groups were averaged to produce mean Satellite, CLC2000 and Combined models. The mean AUC values were 0.69, 0.81 and 0.90 for the CLC2000, Satellite and the Combined model, respectively. The probability of M. calandra presence had the strongest positive correlation with land surface temperature, modified soil adjusted vegetation index, coefficient of variation for ETM+ band 5 and the fraction of non-irrigated arable land.

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

    We report new localities for the lizard Anolis salvini Boulenger, 1885, along the Pacific slopes of the Cordillera Central in Chiriquí province and the Comarca Ngöbe-Buglé of western Panama. These records extend the known geographic distribution of this species about 70 km eastwards. They also extend the known vertical distribution approximately 70 m uphill. Additionally, we provide the first record for the Caribbean slopes, an updated distribution map, photos of specimens from different localities, an analysis of a distress call, and comments on the morphology of this species.

    Reinvestigation of West African Surirellaceae (Bacillariophyta) described by Woodhead and Tweed from Sierra Leone

    Nova Hedwigia 28(2) 121-129.

    Microscope slides containing material from Sierra Leone used by Woodhead and Tweed to describe eight new Surirellaceae taxa in the mid-twentieth century were reinvestigated. Only two taxa were found on the original slides, Surirella approximataWoodhead & Tweed and S. engleri [var. constricta]f. minor Woodhead & Tweed. The valve variability of S. engleri O. Müller includes valves of S. engleri [var. constricta]f. minor which is now regarded as a synonym. As no holotypes were indicated by the authors, types are given here. Comments on S. rudis var. sierra-leonensis Woodhead & Tweed, S. rudis [var. sierra-leonensis]f. constricta Woodhead & Tweed and S. esamangensis Foged are also given. Valves resembling Stenopterobia recta Woodhead & Tweed, Surirella asperrima f. rokuprensis Woodhead&Tweed, S. engleri f. sierra-leonensisWoodhead&Tweed and S. rokuprensisWoodhead&Tweed could not be found on the Woodhead and Tweed original slides.

    Range Expansion of Ambrosia artemisiifolia in Europe Is Promoted by Climate Change

    ISRN Ecology 2013 1-9.

    Ambrosia artemisiifolia L., native to North America, is a problematic invasive species, because of its highly allergenic pollen.Te species is expected to expand its range due to climate change. By means of ecological niche modelling (ENM), we predict habitat suitability for A. artemisiifolia in Europe under current and future climatic conditions.Overall, we compared the performance and results of 16 algorithms commonly applied in ENM. As occurrence records of invasive species may be dominated by sampling bias,wealsouseddatafromthe native range. To assess thequality of themodelling approaches we assembledanewmap of current occurrences of A. artemisiifolia in Europe. Our results show that ENM yields a good estimation of the potential range of A. artemisiifolia in Europe only when using theNorth American data. A strong sampling bias in the European Global Biodiversity Information Facility (GBIF) data for A. artemisiifolia causes unrealistic results.Using theNorthAmerican data reflects the realized European distribution very well. All models predict an enlargement and a northwards shiſt of potential range in Central and Northern Europe during the next decades. Climate warming will lead to an increase and northwards shiſt of A. artemisiifolia in Europe.

    Interspecific Variations of Inner Ear Structure in the Deep-Sea Fish Family Melamphaidae.

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

    Inner ear structures are compared among three major genera of the deep-sea fish family Melamphaidae (bigscales and ridgeheads). Substantial interspecific variation is found in the saccular otoliths, including the presence of a unique otolithic "spur" in the genera Melamphaes and Poromitra. The variation in the saccular otolith is correlated with an increase in the number of hair bundle orientation groups on the sensory epithelia from the genera Scopelogadus to Poromitra to Melamphaes. The diverse structural variations found in the saccule may reflect the evolutionary history of these species. The sensory hair cell bundles in this family have the most variable shapes yet encountered in fish ears. In the saccule, most of the hair bundles are 15-20 μm high, an exceptional height for fish otolithic end organs. These bundles have large numbers of stereovilli, including some that reach the length of the kinocilium. In the utricle, the striolar region separates into two unusually shaped areas that have not been described in any other vertebrates. The brains in all species have a relatively small olfactory bulb and optic tectum, as well as an enlarged posterior cerebellar region that is likely to be involved in inner ear and lateral line (octavolateral) functions. Data from melamphaids support the hypothesis that specialized anatomical structures are found in the ears of some (if not most) deep-sea fishes, presumably enhancing their hearing sensitivity.

    The Use of Climatic Niches in Screening Procedures for Introduced Species to Evaluate Risk of Spread: A Case with the American Eastern Grey Squirrel

    PloS one 8(7) e66559.

    Species introduction represents one of the most serious threats for biodiversity. The realized climatic niche of an invasive species can be used to predict its potential distribution in new areas, providing a basis for screening procedures in the compilation of black and white lists to prevent new introductions. We tested this assertion by modeling the realized climatic niche of the Eastern grey squirrel Sciurus carolinensis. Maxent was used to develop three models: one considering only records from the native range (NRM), a second including records from native and invasive range (NIRM), a third calibrated with invasive occurrences and projected in the native range (RCM). Niche conservatism was tested considering both a niche equivalency and a niche similarity test. NRM failed to predict suitable parts of the currently invaded range in Europe, while RCM underestimated the suitability in the native range. NIRM accurately predicted both the native and invasive range. The niche equivalency hypothesis was rejected due to a significant difference between the grey squirrel’s niche in native and invasive ranges. The niche similarity test yielded no significant results. Our analyses support the hypothesis of a shift in the species’ climatic niche in the area of introductions. Species Distribution Models (SDMs) appear to be a useful tool in the compilation of black lists, allowing identifying areas vulnerable to invasions. We advise caution in the use of SDMs based only on the native range of a species for the compilation of white lists for other geographic areas, due to the significant risk of underestimating its potential invasive range.

    Ancient DNA reveals that bowhead whale lineages survived Late Pleistocene climate change and habitat shifts

    Nature communications 4 1677.

    The climatic changes of the glacial cycles are thought to have been a major driver of population declines and species extinctions. However, studies to date have focused on terrestrial fauna and there is little understanding of how marine species responded to past climate change. Here we show that a true Arctic species, the bowhead whale (Balaena mysticetus), shifted its range and tracked its core suitable habitat northwards during the rapid climate change of the Pleistocene–Holocene transition. Late Pleistocene lineages survived into the Holocene and effective female population size increased rapidly, concurrent with a threefold increase in core suitable habitat. This study highlights that responses to climate change are likely to be species specific and difficult to predict. We estimate that the core suitable habitat of bowhead whales will be almost halved by the end of this century, potentially influencing future population dynamics.

    From southern refugia to the northern range margin: genetic population structure of the common wall lizard, Podarcis muralis

    Journal of Biogeography.

    Aim Thermophilic species persisted in southern refugia during the cold phases of the Pleistocene, and expanded northwards during warming. These processes caused genetic imprints, such as a differentiation of genetic lineages and a loss of genetic diversity in the wake of (re)colonization. We used molecular markers and species distribution models (SDMs) to study the impact of range dynamics on the common wall lizard, Podarcis muralis, from southern refugia to the northern range margin. Location Parts of the Western Palaearctic. Methods We genotyped 10 polymorphic microsatellites in 282 individuals of P. muralis and sequenced the mitochondrial DNA (mtDNA) cytochrome b gene to study the genetic structure, divergence times and ancestral distribu- tions. Furthermore, we generated SDMs for climate scenarios for 6 and 21 ka derived from two different global circulation models. Results We detected two major mtDNA lineages – a western France clade (Pyrenees to Brittany), and an eastern France clade (southern France to Germany, Belgium and Luxembourg). This split was dated to c. 1.23 Ma. The latter clade was divided into two subclades, which diverged c. 0.38 Ma. Genetic diversity of microsatellites within each clade was nested and showed a significant loss of genetic diversity from south to north, a strong pattern of allele surfing across nearly all loci, and an increase in genetic differentiation towards the northern range margin. Results from SDMs suggest that southward range retraction during the late glacial period split the distribution into geographically distinct refugia. Main conclusions The strong genetic differentiation mirrors the effects of long-term isolation of P. muralis in multiple refugia. Post-glacial recolonization of Northern Europe has taken place from two distinct refugia, most probably along river systems (Rh^ one, Rhine, Moselle) and along the Atlantic coastline, with subsequent nested elimination of genetic diversity and increasing genetic differentiation at the northern range margin.
