Pyrethroid insecticides along the Southwestern Atlantic coast: Guiana dolphin (Sotalia guianensis) as a bioindicator

Condutores turísticos podem exercer um papel relevante para o desenvolvimento sustentável do ecoturismo, sendo responsáveis pela condução dos turistas durante a visitação, promoção da sensibilização ambiental e cultural e contribuição no monitoramento de impactos socioambientais no local de visitação. Este estudo teve como objetivo descrever quem são e o que pensam os condutores de embarcações turísticas para observação de botos-cinza (Sotalia guianensis). Para tanto, foi registrada a interação entre condutores turísticos e turistas durante 22 passeios de observação de botos-cinza realizados entre 2014 e 2018 na Reserva de Fauna Costeira de Tibau do Sul (REFAUTS), Rio Grande do Norte, Brasil. Adicionalmente, 22 questionários foram aplicados aos condutores de embarcações turísticas na REFAUTS, em maio de 2017 e julho de 2018. Durante os 22 passeios monitorados, os turistas não receberam qualquer informação sobre a REFAUTS ou receberam informação insuficiente sobre a biologia e ecologia de botos-cinza. De acordo com as respostas obtidas nos questionários, condutores turísticos da REFAUTS são predominantemente jovens, com nível de escolaridade fundamental e têm esta atividade como principal fonte de renda. Estes condutores declararam trabalhar na REFAUTS há pelo menos sete anos e ter conhecimento insuficiente sobre a existência desta Reserva. Uma parte significativa destes profissionais também declarou desconhecer a Lei Municipal nº 349/2007, que regulamenta o transporte marítimo na REFAUTS. Contudo, estes condutores declararam reconhecer a importância dos seguintes aspectos ambientais para a REFAUTS: boto-cinza, ambiente marinho protegido, normas de conduta, programa de fiscalização e cobrança da taxa turística para a REFAUTS. Os resultados deste estudo poderão subsidiar programas de educação ambiental voltados para os condutores turísticos, tornando-os importantes aliados na conservação de botos-cinza e agentes multiplicadores no processo de sensibilização ambiental de turistas na REFAUTS. Who are and what think the guiana dolphin-watching operators? Tour operators can play a relevant role in the sustainable development of ecotourism, being responsible for driving tourists during the visitation, promoting environmental and cultural awareness and contributing to the monitoring of social-environmental impacts in the place of visitation. This study aimed to describe who are and what think the Guiana dolphin-watching operators. We recorded the interaction between dolphin-watching operators and tourists during 22 tours conducted between 2014 and 2018 in the Coastal Wildlife Reserve of Tibau do Sul (REFAUTS), Rio Grande do Norte State, Brazil. In addition, 22 questionnaires were applied to dolphin-watching operators at the REFAUTS in May 2017 and July 2018. During the 22 tours monitored, tourists did not receive any information about the REFAUTS or received insufficient information about the biology and ecology of Guiana dophin (Sotalia guianensis). According to the answers obtained in the questionnaires, dolphin-watching operators are predominantly young, with elementary scholarly and have this activity as the main source of income. These dolphin-watching operators reported that they have worked in the REFAUTS for at least seven years and that they have insufficient knowledge about the existence of this Reserve. A significant number of these professionals also reported that they do not know the Municipal Law no 349/2007, which regulates maritime transport at the REFAUTS. However, these dolphin-watching operators reported that they recognize the importance of the following environmental aspects for the REFAUTS: Guiana dolphin, protected marine area, codes of conduct, inspection program and tourist tax for the REFAUTS. The results of this study may subsidize environmental education programs for dolphin-watching operators, making them important partners in the conservation of Guiana dolphin and multipliers in the process of environmental awareness of tourists in the REFAUTS.

Species Being

Despite being one of the most speciose families, Epitoniidae still remains at present as one of the least understood gastropod families worldwide. This is a consequence of most of the species being only known from shell morphology, added to the wide intraspecific variability of this character and the fact that shell morphology has proven to have frequent examples of parallelisms and convergences among different (unrelated) species. Knowledge of other morphological and anatomical characters in this group is still in its first steps, and such information is currently available for a limited number of species, thus being difficult (when not impossible) to evaluate its taxonomic value. The aim of this study is to re-evaluate the diversity of Epitoniidae occurring in the Atlantic coast of Patagonia. As part of this study, the validity of only four of the six species described / reported from this area could be confirmed: Epitonium georgettinum, E. striatellum, E. fabrizioi and “Cirsotrema” magellanicum. In addition, three new species were recognized and are described herein: Epitonium evanidstriatum, “Cirsotrema” ctenodentatum and “Cirsotrema” strebeli. Information on the shell (including the protoconch), operculum, radula and jaw for these species is here provided, in most cases for the first time. A neotype for Scalaria magellanica is here designated. Furthermore, “Cirsotrema” georgeanum is here proposed as a replacement name for Scalaria fenestrata Strebel, 1908 (not Meneghini in de Stefani, 1875, nor Scalaria fenestrata Wöhrmann, 1889); and that taxon is regarded as a full species, instead of as a synonym of “Cirsotrema” magellanicum, as suggested in some previous publications. This study reveals that the usage of isolated (either morphological or anatomical) characters is usually insufficient for identifying some of the species from Patagonia; however, if these characters are combined, all species may be clearly recognized.
