Connatural alterations can be deformations or malformations discovered in the embryonic development phase of the animal, which can disguise structures or roles of the systems. Congenital disorders can range from small changes, slight changes, serious adulterations and also genetic inconsistencies. There are no apparent defined reasons, and these changes may be caused by environmental and genetic factors. Pigopagus twins are joined at the back, have a coccyx, the gastrointestinal tract may have a single or separate rectum, a single bladder in some cases and obligatorily separate spinal cord and always with sharing of the pelvic bones. The ischiopagus are united by the ventral region from the navel to the pelvis, two sacrum and two pubic symphysis, in addition to a single gastrointestinal tract and a varied number of limbs. Reporting and discussing the morphological and anatomical deformities presented in a species of Squalus acanthias, recorded by LOPES in 2020, is a big step to better understand the anatomy and physiology of animals, which are considered the top of the food chain in the oceans and are in serious trouble. risk of extinction. RESUMO Alterações conaturais podem ser deformações ou más-formações descobertas na fase de desenvolvimento embrionário do animal, podendo disfarçar estruturas ou papéis dos sistemas. Os distúrbios congênitos podem ocorrer desde pequenas mudanças, alterações leves, adulterações sérias e também incoerências genéticas. Não existem motivos aparentes definidos, podendo estas alterações serem causados por fatores ambientais e genéticos. Os gêmeos Pigopagus são unidos pelo dorso, apresentam um coccix, o trato gastrointestinal pode apresentar reto único ou separado, bexiga única em alguns casos e obrigatoriamente medula espinhal separada e sempre com compartilhamento dos ossos pélvicos. Os isquiópagos apresentam-se unidos pela região ventral do umbigo à pelve, dois sacros e duas sínfises púpicas além de tratos gastrointestinal único e número de membros variados. Relatar e discutir as deformidades morfológicas e anatômicas apresentadas em uma especie de Squalus acanthias, registrada por LOPES em 2020, é um grande passo para entender melhor a anatomia e fisiologia de animais, que são considerados o topo da cadeia alimentar nos oceanos e correm um sério risco de extinção.

In the last few years, groundwater management has concentrated on the protection of groundwater quality. An increasing number of countries has adopted policies to protect vital groundwater resources from deterioration by regulating human interaction with the subsurface, the use of potential contaminants, land use restrictions, and waste transport and storage. One of the more common regulatory approaches to the protection of groundwater focuses on public water supplies to reduce the potential of human exposure to hazardous contaminants. Under the framework of the Safe Drinking Water Act amended by U.S. Congress in 1986, The U.S.EPA (1987) issued guidelines for the delineation of wellhead protection areas, recommending the use of analytical and numerical models for the identification of such areas. In this study, the theoretical background for the development of one such numerical model is presented. Two real-world applications are discussed: in the first case history, the model is applied to a Superfund Site in Puerto Rico as a tool for assessment of the effectiveness of a proposed pump-and-treat scheme for aquifer remediation. Based on simulation results for the evolution of the existing contaminant plume it was verified that such a scheme would not work with the proposed purging wells. The second case history is the delineation of a wellhead protection area in the Town of Littleton, Massachusetts, and subsequent design of a monitoring well network.

In 2018–2019, we conducted mosquito collections in a municipal vehicle impound yard, which is 10 km from the Serra do Mar Environmental Protection Area in Santo André, SP, Brazil. Our aim is to study arboviruses in the impound yard, to understand the transmission of arboviruses in an urban environment in Brazil. We captured the mosquitoes using human-landing catches and processed them for arbovirus detection by conventional and quantitative RT-PCR assays. We captured two mosquito species, Aedes aegypti (73 total specimens; 18 females and 55 males) and Ae. albopictus (34 specimens; 27 females and 7 males). The minimum infection rate for DENV-2 was 11.5 per 1000 (CI95%: 1–33.9). The detection of DENV-2 RNA in an Ae. albopictus female suggests that this virus might occur in high infection rates in the sampled mosquito population and is endemic in the urban areas of Santo André. In addition, Guadeloupe mosquito virus RNA was detected in an Ae. aegypti female. To our knowledge, this was the first detection of the Guadeloupe mosquito virus in Brazil.

For over a thousand years, Hippocrates and Galen have been the Alpha and Omega of medical knowledge. Despite the importance of their contributions to clinical and theoretical medicine, they lacked a true understanding of anatomy and physiology. Hippocrates is commonly associated with proposing the doctrine of «tissue fluids», or humoral pathology, and his book, «On the Nature of Man», promotes this point of view. Galen became inherited the knowledge of Hippocrates. Ultimately, he was recognized as one of the most influential physicians of all time. The number of his works was enormous: he wrote more than a hundred books, which were widely distributed. One of Galen’s main commandments was the rule of harmony: all body systems are balanced; disease is a result of an imbalance. As one might expect, some of his ideas, however, were erroneous. Aristotle considered the pancreas, due to its location in the abdominal cavity, as an organ which only task was to protect the adjacent vessels. In an era when unknown diseases wreaked havoc, the concept of known causes of diseases led to the fascination with the study of food poisons and their antidotes. This was common among aristocracy who felt particularly vulnerable to this kind of threats. According to legend, one of the most famous connoisseurs of poisons was Mithridates VI. Pedanius Dioscorides was a Greek who served in the Roman army during the reign of the emperor Nero. The wandering nature of life led him to study a large number of diseases and medicines. The catalogue of his medicinal herbs and plants became the basis for the study and understanding of the medicinal properties of plants. Liver was considered the source of divine prophecy in many ancient cultures. The anatomy of liver was well known in ancient Babylon: a huge number of clay tablets and objects were left, which testify to the importance of «hepatoscopy» in the Middle East as a form of prediction. Those who used the insides of animals for divination (e.g., haruspices — divine interpreters of the future, using the liver as a prediction tool), could be considered the first official anatomists, since the understanding of the future depended on accurate knowledge and interpretation of certain liver components. After the victory of the Assyrian king Sargon over the forces of Urartu and Zikirti in 718 BC, Sargon wanted to appease the gods by sacrificing animals; in doing so, he studied their livers for predictions. Although the concept of pancreas is rooted in ancient times, as evidenced by the comments of haruspices and priests, knowledge of the organ functions eluded humanity until the works by Danish physiologists Francis Sylvius and Regnier de Graaf. Prior to their studies of pancreatic secretion and the elucidation of the role of pancreas in digestion, described by van Helmont and Albrecht von Haller, most researchers focused on the anatomical description of the organ. If the ancient Assyrians and Mesopotamians did not believe that liver predicts the future, but believed that it was pancreas that did it, then pancreatology may have earlier origins. Maimonides, a Jewish scholar and humanist, was also influential in other fields: he condemned astrology and its attempts to calculate the time of the Messiah’s coming. In the field of medicine, he paid attention to prevention, and was interested in the treatment of diseases of the gastrointestinal tract. By the beginning of our era, ideas about digestion, diseases of the digestive tract and their treatment remained very vague. There was a long and difficult way ahead in this area.

ABSTRACT Dimorphandra mollis is native to the Brazilian Savanna and has social, economic and environmental importance. This study aimed to evaluate the yield and diametric distribution of Dimorphandra mollis Benth. in the Pandeiros River Environmental Protection Area, in Bonito de Minas, Minas Gerais state, Brazil. Five areas were assessed, totaling five hectares (50 plots of 1,000 m2). The total number of plants, yield per plant (2018, 2019 and 2020) and diameter at breast height were recorded, considering all trees from the plots in diametric classes. The average diameter at breast height of all plants was 6.05 ± 3.07 cm, and that of the plants that produced in at least one of the evaluated years was 7.46 ± 3.15 cm. The diametric distribution showed classes with no individuals, indicating imbalance, as well as a trend to inverted “J” shape. The maximum annual yield was 8.08 kg ha-1 of dry fruits (2019), the minimum 0.42 kg ha-1 (2018), and the average 2.74 kg ha-1, with biennial characteristic.

The present work aimed to examine the potentials of SAR RADARSAT-1 images to detect emergent coral reefs at the Environmental Protection Area of "Costa dos Corais". Multi-view filters were applied and tested for speckle noise reduction. A digital unsupervised classification based on image segmentation was performed and the classification accuracy was evaluated by an error matrix built between the SAR image classification and a reference map obtained from a TM Landsat-5 classification. The adaptative filters showed the best results for speckle suppression and border preservation, especially the Kuan, Gamma MAP, Lee, Frost and Enhanced Frost filters. Small similarity and area thresholds (5 and 10, respectively) were used for the image segmentation due to the reduced dimensions and the narrow and elongated forms of the reefs. The classification threshold of 99% had a better user's accuracy, but a lower producer's accuracy because it is a more restrictive threshold; therefore, it may be possible that it had a greater omission on reef classification. The results indicate that SAR images have a good potential for the detection of emergent coral reefs.

Abstract Amphibian research has grown steadily in recent years in the Amazon region, especially in the Brazilian states of Amazonas, Pará, Rondônia, and Amapá, and neighboring areas of the Guiana Shield. Even so, few data are available for the Amazonian savannas of Brazil. To contribute to the understanding of the diversity of the amphibians of these savannas, we surveyed 15 temporary ponds, six located in open areas, seven on the edge of savanna forest, and two within the forest, in the savanna of the Rio Curiaú Environmental Protection Area (EPA) in Macapá, in the state of Amapá, northern Brazil. Sampling occurred from May 2013 to August 2014 during periods when the ponds contained water. Amphibians were sampled through visual and auditory surveys conducted during both the day- and the nighttime periods on seven days each month over a total of 84 days. A total of 1574 individuals belonging to four families, 12 genera, and 28 species were recorded during the surveys. The cumulative species curve reached the asymptote, indicating that sampling effort was adequate. The number of species was 25% higher than that reported in other studies in Amazonian savannas. Twelve species were recorded for the first time in the savanna of Amapá. Lysapsus boliviana was the most common species (n = 332 of the individuals recorded). The greatest amphibian species richness found in the Rio Curiaú EPA was associated with the savanna mosaic, forest patches, lowland swamp, and temporary ponds. The results of this study contribute to the understanding of the diversity of amphibian species in the Guianan area of endemism in northern Brazil, and also the Amazonian savannas.
