    Samples of industrialized strawberry pulps, commercialized in Minas Gerais state, Brazil, were collected in the period from 2006 to 2007 by the Sanitary Surveillances, and were sent to Fundação Ezequiel Dias for analysis of pesticide residues. It was performed the extraction by multi-residue method with acetone, dichloromethane and hexane. The obtained extracts were analyzed by gas chromatography with detectors of electron capture (GC-ECD), flame photometric (GC-FPD), nitrogen phosphorus (GC-NPD), mass spectrometry (GC-MS) and high performance liquid chromatography (HPLC) with UV visible and fluorescence detectors. The results showed the inappropriate use of pesticides, which are not authorized as acephate, captan, chlorfenapyr, chlorpyrifos, dimethoate, omethoate, endosulfan, fenarimol, folpet, methamidophos, prochloraz and tetradifon, and the permitted ones azoxystrobin, difenoconazole, fenpropatrina, iprodione and procymidone. These indicate that good agricultural practices are not being followed by some producers, and demonstrate the necessity of processed food fiscalization, which will lead to products of better quality.Amostras de polpas de morango industrializadas, comercializadas no estado de Minas Gerais, foram coletadas no período de 2006 a 2007 pelas Vigilâncias Sanitárias e encaminhadas à Fundação Ezequiel Dias para análise de resíduos de agrotóxicos. Realizou-se a extração pelo método de multirresíduos com acetona, diclorometano e hexano. Os extratos obtidos foram submetidos à análise por cromatografia a gás com detectores de captura de elétrons (CG-DCE), fotométrico de chama (CG-DFC) e nitrogênio fósforo (CG-DNF), espectrometria de massa (CG-MS) e cromatografia a líquido de alta eficiência (CLAE) com detectores ultravioleta (UV) visível e fluorescência. Os resultados evidenciaram o uso inadequado de agrotóxicos, sendo detectados produtos não autorizados como acefato, captana, clorfenapir, clorpirifós, dimetoato, ometoato, endossulfam, fenarimol, folpete, metamidofós, procloraz e tetradifona e os autorizados azoxistrobina, difenoconazol, fenpropatrina, iprodiona e procimidona. Isso indica que as boas práticas agrícolas não estão sendo cumpridas por alguns produtores e mostra a necessidade de fiscalização de alimentos processados, o que levaria à oferta de produtos de melhor qualidade

    MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

    Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.

    This research aims to design, implement and evaluate a blended collaborative training program (CTP), in Preschool Education (EPE), integrated in the project "Invisible Limits: Education in a Nature Environment" (LI) and with the Kindergartens (JI) that participate in it, in order to articulate educational practices in external contexts, namely nature, and interior. The project emerged from the concerns pointed out by current research regarding the lack of opportunities for action by children in the space nature and its repercussions on their health and cognitive development, socio-emotional, motor and environmental awareness. Through a case study, of qualitative nature, it is intended to evaluate the contributions of the CTP referred, on the one hand, in the reorientation of the conceptions and educational practices of four educators before and after their participation in the CTP, using multiple techniques of data collection and processing - researcher's journal, documentary analysis, semi-structured interviews, participant observation, written, photographic and video records and content analysis with Webqda software support, and, on the other hand, the quality of the experiences developed with twenty-four children, through the application of the emotional well-being and implication scale of Portugal and Laevers (2018), before, during and after the CTP. The study may contribute to the development of innovative strategies in diverse contexts, in a crosscutting approach, through collaborative and articulated work among professionals - researchers, coordinators, educators, auxiliaries and specialists in nature environment education. Ultimately, the relevance of this project comes from the need for research, training and intervention in the area, as well as the contribution and implications it aspires to achieve in the quality of educational and training offerings in Portugal.publishe

    Hidden in our pockets: building of a DNA barcode library unveils the first record of Myotis alcathoe for Portugal

    The advent and boom of DNA barcoding technologies have provided a powerful tool for the fields of ecology and systematics. Here, we present the InBIO Barcoding Initiative Database: Portuguese Bats (Chiroptera) dataset containing DNA sequences of 63 specimens representing the 25 bat species currently known for continental Portugal. For that, we sequenced tissues samples obtained in a vast array of projects spanning the last two decades.We added four new Barcoding Index Numbers (BINs) to existing Chiroptera barcodes on BOLD, two belonging to Myotis escalerai, one to Plecotus auritus and the other to Rhinolophus hipposideros. Surprisingly, one of the samples initially identified in the field as Myotis mystacinus turned out to be Myotis alcathoe, which represents the first record of this species for Portugal. The presence of Nyctalus noctula in Portugal was also genetically confirmed for the first time. This case study shows the power and value of DNA barcoding initiatives to unravel new data that may be hidden on biological collections

    Objective: To estimate the risk of cadmium (Cd) contamination through the ingestion of fish by a population of fish consumers in Sepetiba Bay-SE, Brazil. Methods: We estimated the risk of cadmium intake for fish consumers in the study area. For control purposes we based it on fish consumption by the population, making it possible to estimate the probability and risk due to cadmium intake by means of the assessment of hazard quotient (HQ). Results: The risk for cadmium intake was 110 times greater than that found in control population. The HQ was 0.11, and compared with control population, which is located around the area of study, the risk ratio was 0.001. The increased risk may be reflected in renal disease, although these have not been shown to be associated with exposure to Cd. Conclusion: The fishermen who work in Sepetiba Bay have a risk about 110 times greater for cadmium contamination than the population that consumes fish for 48 days per year (average).Objetivo: Estimar o risco de contaminação por cádmio (Cd) através da ingestão de peixe em população consumidora de pescado, na Baía de Sepetiba-SE, Brasil. Métodos: Estimouse o risco de ingestão de cádmio para os consumidores de peixe da área de estudo. Para o controle, baseou-se no consumo de peixe pela população brasileira, tornando possível estimar a probabilidade e risco devido à ingestão de cádmio por avaliação do quociente de perigo (HQ). Resultados: O risco para a ingestão de cádmio foi 110 vezes maior do que o encontrado no controle populacional. O HQ foi de 0,11; e quando comparado com o controle da população, que está localizado ao redor da área de estudo, o risco obtido foi de 0,001. O risco aumentado pode ser refletido nas doenças renais, embora estas não tenham se mostrado associadas à exposição ao Cd. Conclusão: Os pescadores que trabalham na Baía de Sepetiba têm um risco cerca de 110 vezes maior de contaminação por cádmio do que a população que consome peixe por 48 dias por ano (média

    The BioSTP: DNA Barcoding of endemic birds from oceanic islands of the Gulf of Guinea dataset contains records of 155 bird specimens belonging to 56 species in 23 families, representing over 80% of the diversity of the breeding landbird community. All specimens were collected on Príncipe, São Tomé and Annobón Islands between 2002 and 2021 and morphologically identified to species or subspecies level by qualified ornithologists. The dataset includes all endemic species and 3/4 of the extant endemic subspecies of the islands. This dataset is the second release by BioSTP and it greatly increases the knowledge on the DNA barcodes of Gulf of Guinea birds. All DNA extractions are deposited at Associação BIOPOLIS - CIBIO, Research Center in Biodiversity and Genetic Resources.The dataset includes DNA barcodes for all 29 endemic bird species and for 11 of the 15 extant endemic bird subspecies from the oceanic islands of the Gulf of Guinea. This is the first major DNA barcode set of African birds. The three endemic subspecies of Crithagra rufobrunnea, an island endemic with three allopatric populations within the Archipelago, are also represented. Additionally, we obtained DNA barcodes for 16 of the 21 non-endemic landbirds and for one vagrant (Sylvia communis). In total, forty-one taxa were new additions to the Barcode of Life Data System (BOLD), with another 11 corresponding to under-represented taxa in BOLD. Furthermore, the submitted sequences were found to cluster in 55 Barcode Index Numbers (BINs), 37 of which were new to BOLD. All specimens have their DNA barcodes publicly accessible through BOLD online database and GenBank
