We describe a population of pipistrelle-like bats from Príncipe Island (Gulf of Guinea, Western Central Africa) as a new species based on the molecular and morphological characteristics of six specimens collected more than 30 years ago. The description of this new species was not possible until the traditionally entangled systematics of the whole pipistrelle group was clarified in recent years with the inclusion of molecular techniques and adequate species sampling. In this new taxonomic framework, the new species was clearly included within the dark-winged group of the recently described genus Pseudoromicia. The pipistrelles from Príncipe Island present a moderately inflated skull in lateral view with inner upper incisors that are moderately bicuspids and a baculum distinctly long with expanded tips. Besides these morphological characters, the new bat species is distinguished by its dwarfism, being the smallest species recognized within the genus. The ecology and conservation status of this endemic island species are unknown and field studies are urgently needed to evaluate the situation and conservation threats to this new species in its natural habitat.

Despite being one of the most common congenital hand abnormalities in humans, polydactyly remains extremely rare in bats. To date, it has been observed only in two insectivorous families in North America (Molossidae and Vespertilionidae) and a single case for the New World fruit bats (Phyllostomidae). We report the first case of polydactyly in a European bat – a Myotis daubentonii (Vespertilionidae), with eight toes. The bat was found alive, hibernating in the Natura 2000 site (PLH080003 “Nietoperek”) in Poland.

Appropriate waste and resource management are essential for a sustainable circular economy with reduced environmental impact. With critical resources, e-waste may serve as indirect raw material. For example, with NdFeB permanent magnets, Neodymium (Nd) and the co-present Dysprosium (Dy) are critical rare earth elements (REEs). However, there exists no economically viable technology for recycling them from electronic waste (e-waste). Here, a method is presented based on cloud point extraction (CPE). The work involves basic complexation chemistry in a cloud medium with pure REE salts, as well as, with real NdFeB-magnets (nearly 28% REE content by weight) from an old hard disk drive (5.2 g magnet in a 375 g HDD). High extraction efficiency (>95%) was achieved for each REE targeted (Nd, Dy, Praseodymium (Pr)). With the magnet waste, the cloud phase did hardly contain any Nickel (Ni), Cobalt (Co), or Boron (B), but some Aluminium (Al) and Iron (Fe). Dynamic light scattering results indicated aggregation of ligand-surfactant micelles with the cloud phase. The preconcentrated products can be used for new Nd magnet manufacturing or further enriched using established transition metal removal techniques. Reuse of solvent, low chemical inventory demand, and using non-inflammable, non-volatile organic extractants promise safe large-scale operation, low process costs, and less environmental impact than using hydrometallurgical methods used with urban or primary mining., Journal of molecular liquids, 382, ISSN:0167-7322, ISSN:1873-3166

Nanoparticles (NPs) have wide applications in physical and chemical processes, and their individual properties (e.g., shape, size, and composition) and ensemble properties (e.g., distribution and homogeneity) can significantly affect the performance. However, the extrapolation of information from a single particle to the ensemble remains a challenge due to the lack of suitable techniques. Herein, we report a high-throughput single-particle inductively coupled plasma mass spectrometry (SP-ICP-MS)-based protocol to simultaneously determine the size, count, and elemental makeup of several thousands of (an)isotropic NPs independent of composition, size, shape, and dispersing medium with atomistic precision in a matter of minutes. By introducing highly diluted nebulized aqueous dispersions of NPs directly into the plasma torch of an ICP-MS instrument, individual NPs are atomized and ionized, resulting in ion plumes that can be registered by the mass analyzer. Our proposed protocol includes a phase transfer step for NPs synthesized in organic media, which are otherwise incompatible with ICP-MS instruments, and a modeling tool that extends the measurement of particle morphologies beyond spherical to include cubes, truncated octahedra, and tetrahedra, exemplified by anisotropic Cu NPs. Finally, we demonstrate the versatility of our method by studying the doping of bulk-dilute (

Owing to major technological advances, bioacoustics has become a burgeoning field in\ud ecological research worldwide. Autonomous passive acoustic recorders are becoming widely\ud used to monitor aerial insectivorous bats, and automatic classifiers have emerged to aid\ud researchers in the daunting task of analyzing the resulting massive acoustic datasets.\ud However, the scarcity of comprehensive reference call libraries still hampers their wider\ud application in highly diverse tropical assemblages. Capitalizing on a unique acoustic dataset\ud of more than 650,000 bat call sequences collected over a 3-year period in the Brazilian\ud Amazon, the aims of this study were (a) to assess how pre-identified recordings of free-flying\ud and hand-released bats could be used to train an automatic classification algorithm (random\ud forest), and (b) to optimize acoustic analysis protocols by combining automatic classification\ud with visual post-validation, whereby we evaluated the proportion of sound files to be postvalidated\ud for different thresholds of classification accuracy. Classifiers were trained at species\ud or sonotype (group of species with similar calls) level. Random forest models confirmed the\ud reliability of using calls of both free-flying and hand-released bats to train custom-built\ud automatic classifiers. To achieve a general classification accuracy of ~85%, random forest\ud had to be trained with at least 500 pulses per species/sonotype. For seven out of 20 sonotypes,\ud the most abundant in our dataset, we obtained high classification accuracy (>90%). Adopting\ud a desired accuracy probability threshold of 95% for the random forest classifier, we found that\ud the percentage of sound files required for manual post-validation could be reduced by up to\ud 75%, a significant saving in terms of workload. Combining automatic classification with\ud manual ID through fully customizable classifiers implemented in open-source software as\ud demonstrated here shows great potential to help overcome the acknowledged risks and biases\ud associated with the sole reliance on automatic classification.

We report new localities for Callinectes sapidus in the Iberian Peninsula that widen the north-eastern limit of its distribution by more than 206 km along the Iberian Mediterranean coastline. This invasive species has been captured in the estuaries of the Fluvià, Muga and Ter rivers and has become established in the Fluvià River in only nine months since the first individual was detected. These reports show how rapid expansion of C. sapidus can be and that this may be preceded by the presence of isolated individuals We gratefully acknowledge the scientific team of the European Life project “Pletera” (LIFE13 NAT/ES/001001) and the Sorelló S.L. company for sharing their field results.

Human-bat interactions are common in rural areas across the tropics. Over 40 bat species occur in Madagascar, most of which are endemic. Forest loss is changing the distribution of bats throughout the island, with potential increases in both the abundance of synanthropic species and human-bat interactions. We set out to study knowledge of, interactions with, and attitudes towards bats in rural Madagascar, including reports of food and ethnomedicinal uses of bats, their cultural representations in folklore, and the existence of culturally enforced taboos in relation to them. We administered 108 surveys with open- and closed-ended questions with adults from the Tanala and Betsileo ethnic groups living around Ranomafana National Park. Most interviewees mentioned at least two types of bats. Over 10% of the interviewees had consumed bats and ∼20% used bat guano as a fertilizer. Around one-fifth recognized cultural taboos inhibiting bat hunting and consumption and most considered bats not to be dangerous. However, some informants mentioned that bats could carry diseases and complained about the bad smell and noise associated with bat roosts in houses and public buildings. Nearly 25% of the respondents could identify cultural representations of bats in local folklore. Malagasy rural communities interact closely with bats, but severely underestimate the diversity of bat species around them. Taken together, our results greatly increase the understanding of social-ecological complexities of human-bat relationships in rural Madagascar, offer possible pathways for biocultural approaches to conservation, and yield insights applicable to other communities coexisting with bats across the humid tropics.

Chromatic disorders may disrupt adaptive coloration and reduce animals’ capacity to survive and produce young. These disorders have been documented widely for bats across the globe. However, most of these cases are concentrated in regions with well-studied faunal communities, such as Europe or North and South America, with little documentation of chromatic disorders in regions such as Central Africa. We captured a bat in mainland Equatorial Guinea, Central Africa, with distinct white patches on its body and normally pigmented eyes. Here, we report the first recorded case of piebaldism documented in Central Africa for the Nycteridae family, and the first case worldwide for Nycteris arge Thomas, 1903.

In this work, a Total Reflection X-ray fluorescence (TXRF) spectrometry based quantitative methodology for elemental characterization of liquid extracts and solids belonging to old building materials and their degradation products from a building of the beginning of 20th century with a high historic cultural value in Getxo, (Basque Country, North of Spain) is proposed. This quantification strategy can be considered a faster methodology comparing to traditional Energy or Wavelength Dispersive X-ray fluorescence (ED-XRF and WD-XRF) spectrometry based methodologies or other techniques such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS). In particular, two kinds of liquid extracts were analysed: (i) water soluble extracts from different mortars and (ii) acid extracts from mortars, black crusts, and calcium carbonate formations. In order to try to avoid the acid extraction step of the materials and their degradation products, it was also studied the TXRF direct measurement of the powdered solid suspensions in water. With this aim, different parameters such as the deposition volume and the measuring time were studied for each kind of samples. Depending on the quantified element, the limits of detection achieved with the TXRF quantitative methodologies for liquid extracts and solids were set around 0.01–1.2 and 2–200 mg/L respectively. The quantification of K, Ca, Ti, Mn, Fe, Zn, Rb, Sr, Sn and Pb in the liquid extracts was proved to be a faster alternative to other more classic quantification techniques (i.e. ICP-MS), accurate enough to obtain information about the composition of the acidic soluble part of the materials and their degradation products. Regarding the solid samples measured as suspensions, it was quite difficult to obtain stable and repetitive suspensions affecting in this way the accuracy of the results. To cope with this problem, correction factors based on the quantitative results obtained using ED-XRF were calculated to improve the accuracy of the TXRF results.

The development of methods for the analysis of silver nanoparticles (AgNPs) is of special relevance to achieve detailed insights into the fate, transport and exposure of these emerging pollutants in the environment. In the present contribution, for the first time, the possibilities and drawbacks of cloud point extraction (CPE) in combination with total reflection X-ray fluorescence spectrometry (TXRF) have been evaluated for the determination of AgNPs content in soil and consumer product water extracts. The experimental conditions for the separation and preconcentration of AgNPs with different coatings (PVP, PEG and citrate) and sizes (40-100 nm) were evaluated, paying attention to possible modifications required by the characteristics of the TXRF technique. Single particle inductively coupled plasma mass spectrometry (SP-ICPMS) analysis of the same aqueous extracts was also carried out in order to confirm the presence and percentage of AgNPs. Good agreement with respect to AgNPs concentrations in the analysed soil extracts was obtained between CPE-TXRF and SP-ICPMS, confirming the absence of matrix effects for this type of sample by CPE. On the contrary, large discrepancies were found between both analytical approaches for the studied consumer product water extracts. SP-ICPMS analysis evidenced the presence of ionic silver with a heterogeneous mixture of different sizes including relatively large Ag particles ( > 100 nm). This fact was also verified by SEM-EDS analysis. The results from this study highlight the necessity to study in more detail the effectiveness of existing methodologies (including CPE-based methods and SP-ICPMS) for the monitoring of AgNPs in complex aqueous matrices involving mixtures of different NPs sizes and coatings The Spanish Ministry of Economy and Competitiveness financed this work through the project CGL2013-48802-C3-2-R (Program 2014).

The use of bioacoustics as a tool for bat research is rapidly increasing worldwide. There is substantial evidence that environmental factors such as weather conditions or habitat structure can affect echolocation call structure in bats and thus compromise proper species identification. However, intraspecific differences in echolocation due to geographical variation are poorly understood, which poses a number of issues in terms of method standardization. We examined acoustic data for Pteronotus cf. rubiginosus from the Central Amazon and the Guiana Shield. We provide the first evidence of intraspecific geographic variation in bat echolocation in the Neotropics, with calls significantly differing in almost all standard acoustic parameters for the two lineages of this clade. We complement our bioacoustic data with molecular and morphological data for both species. Considerable overlap in trait values prevents reliable discrimination between the two sympatric Pteronotus based on morphological characters. On the other hand, significant divergence in the frequency of maximum energy suggests that bioacoustics can be used to readily separate both taxa despite extensive intraspecific variability in their echolocation across the Amazon. Given the relative lack of barriers preventing contact between bat populations from the Central Amazon and French Guiana, the documented acoustic variation needs to be further studied in geographically intermediate locations to understand the potential isolation processes that could be causing the described divergence in echolocation and to determine whether this variation is either discrete or continuous.

The broad use of silver nanoparticles (AgNPs) in daily life products enhances their possibilities to reach the environment. Therefore, it is important to understand the uptake, translocation and biotransformation in plants and the toxicological impacts derived from these biological processes. In this work, Lactuca sativa (lettuce) was exposed during 9 days to different coated (citrate, polyvinylpyrrolidone, polyethylene glycol) and sized (60, 75, 100 nm) AgNPs at different concentrations (1, 3, 5, 7, 10, 15 mg L−1). Total silver measurements in lettuce roots indicated that accumulation of AgNPs is influenced by size and concentration, but not by nanoparticle coating. On the other hand, nanosilver translocation to shoots was more pronounced for neutral charged and large sized NPs at higher NP concentrations. Single particle inductively coupled plasma mass spectrometry analysis, after an enzymatic digestion of lettuce tissues indicated the dissolution of some NPs. Ag K-edge X-ray absorption spectroscopy analysis corroborated the AgNPs dissolution due to the presence of less Ag-Ag bonds and appearance of Ag-O and/or Ag-S bonds in lettuce roots. Toxicological effects on lettuces were observed after exposure to nanosilver, especially for transpiration and stomatal conductance. These findings indicated that AgNPs can enter to edible plants, exerting toxicological effects on them.

The expansion of silver nanoparticle (AgNP) applications in industry as antibacterial agents has generated an increment of their presence in the environment. Once there, their behavior is not clear because they can undergo different transformation processes that affect their transport, mobility, bioavailability, and toxicity. Therefore, the characterization and quantification of these emerging contaminants are important to understand their behavior and the toxicity effects that can be exerted on living beings. Single particle inductively coupled plasma mass spectrometry (SP-ICPMS) has demonstrated its ability to characterize and give quantitative information on AgNPs in aqueous samples. However, sometimes, the discrimination of the signal corresponding to AgNPs from the signal of dissolved species (Ag(I)) is a challenge. In the present contribution, it is shown that the presence of high amounts of Ag(I) hamper silver nanoparticle size and nanoparticle concentration determination in aqueous samples by SP-ICPMS. To facilitate signal discrimination of both chemical forms, the combination of cloud point extraction (CPE) with SP-ICPMS was studied. CPE experimental conditions to separate AgNPs from Ag(I) were assessed and adapted taking into account the characteristics of the SP-ICPMS technique. CPE and soil matrix effects on particle size were evaluated, showing that particle size was not modified after being in contact with soil matrix and after being separated by CPE. Additionally, frequently used calculation methods for SP-ICPMS data treatment were assessed. Finally, the potential of the developed methodology CPE-SP-ICPMS was evaluated in aqueous soil leachates contaminated with mixtures of AgNPs/Ag(I).

The production of silver nanoparticles (AgNPs)has increased tremendously during recent years due to their antibacterial and physicochemical properties. As a consequence, these particles are released inevitably into the environment, with soil being the main sink of disposal. Soil interactions have an effect on AgNP mobility, transport and bioavailability. To understand AgNP adsorption processes, lab-controlled kinetic studies were performed. Batch tests performed with five different Mediterranean agricultural soils showed that cation exchange capacity and electrical conductivity are the main parameters controlling the adsorption processes. The adsorption kinetics of different sized (40, 75, 100 and 200 nm)and coated (citrate, polyvinylpyrrolidone and polyethyleneglycol (PEG))AgNPs indicated that these nanoparticle properties have also an effect on the adsorption processes. To assess the mobility and bioavailability of AgNPs and to determine if their form is maintained during adsorption/desorption processes, loaded soils were submitted to leaching tests three weeks after batch adsorption studies. The DIN 38414-S4 extraction method indicated that AgNPs were strongly retained on soils, and single-particle inductively coupled plasma mass spectrometry confirmed that silver particles maintained their nanoform, except for 100 nm PEG-AgNPs and 40 nm citrate-coated AgNPs. The DTPA (diethylenetriaminepentaacetic acid)leaching test was more effective in extracting silver, but there was no presence of AgNPs in almost all of these leachates. © 2019, The Spanish Ministry of Economy and Competitiveness financed this work through the project CGL2013-48802-C3-2-R (Program 2014) and L.

17th International Conference on Total Reflection X-Ray Fluorescence Analysis and Related Methods (TXRF) -- SEP 19-22, 2017 -- Brescia, ITALY WOS: 000453493300003 While the nanoscale dimensions give metallic nanoparticles unique physical and chemical properties, their potential release in the environment and subsequent effects on ecosystem health are becoming an increasing concern. In the present contribution, for the first time, a novel and simple analytical approach has been developed for the simultaneous quantification of silver and gold nanoparticles (AgNPs, AuNPs) in aqueous samples. The method combines a sample preparation and enrichment step based on cloud point extraction (CPE) with total reflection X-ray fluorescence spectrometry (TXRF) detection. Experimental conditions enabling the simultaneous extraction and detection of AgNPs and AuNPs were studied in detail. Under the best analytical conditions, limits of detection for AgNPs and AuNPs were 0.3 and 0.2 mu g L-1, respectively. Due to the lack of suitable certified references materials, accuracy of the CPE-TXRF method was tested by analysing several types of spiked water samples, including mineral, tap, river and sea water. Percentage recoveries achieved for the analysis of spiked samples were in all cases in the range of 82-100% for both types of studied NPs, suggesting that the existence of natural colloids, ionic Ag+ and Au3+ species, and other components in environmental waters have little influence on the quantitative determination of AgNPs and AuNPs. The only exception was the recovery obtained in the analysis of the spiked sea water sample that was around 40-50%. However, for salty aqueous samples, the developed analytical approach might still be feasible if the standard addition method is used for calibration purposes. In an attempt to provide additional information on AgNPs and AuNPs behaviour in the environment, the CPE-TXRF method was also applied to study the influence of organic matter content in waters as well as the influence of soil matrix on AgNPs and AuNPs stability.

Despite conservation discourses in Madagascar increasingly emphasizing the role of customary institutions for wildlife management, we know relatively little about their effectiveness. Here, we used semi-structured interviews with 54 adults in eight villages to investigate whether sacred caves and taboos offer conservation benefits for cave-dwelling bats in and around Tsimanampetsotsa National Park, south-west Madagascar. Although some caves were described as sites of spiritual significance for the local communities, most interviewees (c. 76%) did not recognize their present-day sacred status. Similarly, only 22% of the interviewees recognized taboos inhibiting bat hunting and consumption. Legal protection of bats and caves through protected areas was often more widely acknowledged than customary regulations, although up to 30% of the interviewees reported consumption of bats within their communities. Guano extraction was often tolerated in sacred caves in exchange for economic compensation. This may benefit bat conservation by creating incentives for bat protection, although extraction is often performed through destructive and exploitative practices with little benefit for local communities. In view of these results our study questions the extent to which sacred sites, taboos and protected areas offer protection for bats in Madagascar. These results support previous studies documenting the erosion of customary institutions in Madagascar, including the loss of the spiritual values underpinning sacred sites. Given that many Malagasy bats are cave-dwelling species and that most depend on the customary protection of these sites, it is important to obtain a better understanding of the complex interactions between spiritual practices, taboos and protected areas in sustaining bat diversity.

Recent studies predict a future decrease in precipitation across the tropics, particularly the Amazon, likely causing significant droughts that have negative consequences for Amazonian freshwater biomes, especially lakes. Furthermore, immediate consequences of global warming for terrestrial fauna associated with tropical lakes are poorly understood as the vast majority of studies come from temperate regions. Here, we assess the seasonal importance of lakes for the conservation of aerial insectivorous bats in the Central Amazon using passive bat recorders. We compared richness, general bat activity and foraging activity between lakes and adjacent forest. Of a total of 21 species/sonotypes recorded in both habitats, all were detected over lakes, and 18 were significantly more active over lakes than in forest. Only two species had significantly higher activity levels in the forest than at the lakes. Species richness and general bat activity over the lakes were higher in the dry than in the rainy season. Foraging activity was also greater over the lakes than within the forest in both seasons. Moreover, both variables were positively correlated with lake size, although the effect on activity was species-specific. Climate change-driven shrinking of lakes may have detrimental consequences for aerial insectivorous bats, especially for the most water-dependent species. Compared to permanent water bodies of other regions, the value of tropical lakes for functionally important taxa, such as bats, has been understudied. Higher bat activity levels over lakes than in forest in both seasons and comprising the whole ensemble of aerial insectivorous bats of the study region, indicate that lakes embedded in Amazonian terra firme forests deserve special attention for future bat conservation. © 2018 The Authors.

In recent years, the production of silver nanoparticles (AgNPs) has grown due to their antibacterial properties. This fact enhances the release of these particles into the environment, especially in soils that are the major sink. To better understand adsorption processes in soils, usually batch kinetic studies are carried out. In this context, we tested the possibilities of using total reflection X-ray fluorescence spectrometry (TXRF) to monitor the silver content in soil adsorption kinetic studies. It was found that the lower limit of detection for Ag (through Ag-Kα detection) in aqueous solutions was around 37 μg·L− 1, which was suitable to carry out this kind of studies. Moreover, the direct analysis of Ag adsorbed onto soil after the kinetic studies was investigated. In this case, the limit of detection for Ag was around 1.7 mg·kg− 1. All TXRF results were compared with those obtained by inductively coupled plasma optic emission spectrometry and good agreement was found. The batch adsorption tests performed showed that 98% of polyvinylpyrrolidone coated AgNPs were retained on the tested soils in < 6 h The SpanishMinistry of Economy and Competitiveness financed this work through the project CGL2013-48802-C3-2-R (Program 2014).

The advent of rare earth elements (REEs) with optoelectronic properties has shifted the technology paradigm from digital to a smart and hybrid world. Their substantial uses also resulted in a large piling up of e-waste. Therefore, e-waste is now a lucrative recycling target for the recovery of such critical raw materials. Their recycling from e-waste is often challenged by dilute metal concentration, complex composition, and difficult chemical characterisation. Generally, the characterisation of e-waste involves elemental determination techniques, such as inductively coupled plasma optical emission spectroscopy (ICP-OES) or inductively coupled plasma mass spectrometry (ICP-MS). ICP-OES is attractive for a recycling or research sector because it has a higher matrix tolerance and lower cost than ICP-MS. In this work, the intensity at 445 line positions measured by an ICP-OES instrument was compiled in a 2D diagram to map interferences by 27 prominent lines from 9 REEs. The second diagram shows the impact at 230 neighbouring line positions measured in each of, in total, 17 (i.e., 9 REEs and 8 non-REEs) single-standard solutions in terms of the concentration of the element type affected. The spectral interference correction algorithm proposed here had been developed by us for a recycling process to obtain pure Y, Eu, and Tb from fluorescent powder (FP) in spent lamps. The ICP-OES analysis and spectral interference correction approach presented here can be applied to any element and e-waste type. To underline this, the paper gives examples for elements in dissolved FP and surrogate NdFeB magnet samples.
