Identification of tree species from the Peruvian tropical amazon “Selva Central” forests according to wood anatomy

The “Selva Central” of Peru is characterized by its forest species richness that produces quality wood for countless uses. Therefore, it is necessary to identify the wood and its macroscopic anatomy, which is an important tool for the botanical identification of tree species. For this purpose, 13 sawmills located in 3 provinces were selected that exploit several tree species of “Selva Central”. Sampling of representative woods was carried out, identified by common names and, in the laboratory, they were polished, examined, and grouped by the similarity of the macroscopic anatomical structure, leading to the tree species identification. Twenty tree species were identified, belonging to 17 genera, with emphasis on the Lauraceae and Fabaceae families. However, Moraceae, Meliaceae, Lecythidaceae, Euphorbiaceae, Bignoniaceae, Myristicaceae, Combretaceae, and Burseraceae families were also identified. The anatomical structures of all the identified tree species were described, transversal and longitudinal tangential cross section images were collected, and a species identification key was constructed. The implications and importance of tree species identification via wood anatomy were discussed, in terms of controlling forest exploitation, traceability of the production chain, and the future development of an artificial intelligence tree-species identification method.

ABSTRACT Copper (Cu) is an essential micronutrient for plants. However, when in excess, it becomes phytotoxic. In this context, the objective of this study was to evaluate the growth and physiological responses of tree species exposed to different copper concentrations in the soil. Three experiments were carried out, one for each forest species under study: Myroxylon peruiferum ("Óleo Bálsamo"), Hymenaea courbaril ("Jatobá") and Peltophorum dubium ("Canafístula"), with the same doses of copper (0, 50, 100, 200 and 400 mg kg-1). The experimental design was in randomized blocks (DBC), with five copper concentrations and four replicates. The plants were grown on soil substrate packed in 8-dm3 pots and kept in a greenhouse for 90 days. Biometric measurements, chlorophyll, antioxidant enzymes and copper content in tissues were evaluated. Copper did not influence the vegetative growth of the species studied. The content of chlorophyll "a" was reduced with increasing copper concentrations in the soil. H. courbaril had 56 to 92% copper retained in the roots, and the same behavior was observed for P. dubium (77-91%) and M. peruiferum (19-64%). In the three species studied, there was copper bioaccumulation, mainly in the roots, possibly as a metal tolerance strategy, preserving the most active tissues and the photosynthetic machinery. Cu translocation from roots to shoot was very restricted in all species. This behavior, associated with the increase in the activity of some antioxidant enzymes in plants, may indicate the phytoremediation potential of the studied species.

Introdução: Estudos através das imagens da ATM apresentam-se como auxílio ao diagnóstico especifico de determinadas patologias relacionadas a essa estrutura anatômica. De modo a oferecer mais informações possíveis, visualização mais clara, redução das dificuldades de interpretação radiográfica, é imperativa a boa execução das técnicas radiográficas e o desenvolvimento de novos métodos de exposição. Objetivo: Avaliar duas incidências radiográficas convencionais que possibilitam o estudo da ATM e relacioná-las com a qualidade da imagem, de acordo com a visualização das estruturas anatômicas. Materiais e métodos : O estudo foi realizado através da execução de duas técnicas radiográficas (SCHULLER e LAW modificado), utilizadas para estudo da ATM em um simulador com ossos do crânio e mandíbula humana recoberta com resina. A qualidade da imagem foi avaliada por três radiologistas com experiência, que atribuíram escores (01 – inadequado; 02 – aceitável com restrições; 03 – aceitável sem restrições) relacionados à sobreposição das estruturas, à visualização da fossa mandibular e à definição do côndilo. Resultados: Para os três avaliadores, a técnica B apresentou a concordância em 75% dos pontos analisados, observou-se que para a técnica A os avaliadores 1 e 3 concordaram em 75%, enquanto que os indicies kappa foram considerados moderados para a técnica B . Conclusão: As técnicas transcranianas permitem a avaliação anatômica e patológica da ATM como forma simples e mais acessível ao paciente sendo a técnica de Law modificado a que apresenta maior concordância entre os avaliadores. Abstract Introduction: Image studies of the temporal mandibular joint (TMJ) are presented as an assistance to the diagnosis of certain specific pathologies related to this anatomical structure. In order to provide as much information as possible, a clearer view and a reduction in the difficulty of the radiographic interpretation it is imperative a good performance of the radiographic techniques and the development of new exposure methods. Objective: Evaluate two conventional radiographic views that allow the study of TMJ and relate them with the image quality according to the visualization of anatomical structures Materials and Methods: The study was conducted by running two radiographic techniques (SCHULLER and modified LAW) used to the TMJ study in a phantom containing cranial bones and a human mandibular covered with resin. The image quality was evaluated by three experienced radiologists assigning scores (01 - inappropriate, 02 - acceptable with restrictions, 03-acceptable without restrictions) related to overlapping structures, visualization of the glenoid fossa and condyle definition. Results: For three evaluators, B technique presented an agreement on 75% of the points analyzed. It was observed that for technique A, evaluators 1 and 3 evaluators agreed on 75% while the kappa indexwere considered moderated for B technique. Conclusion: Transcranial techniques allow anatomical and pathological assessment of the TMJ in a simple and more accessible way to the patient and the technique of modified Law presents the best agreement between raters.

The anatomical structure of phonation in the domestic chicken Gallus gallus (red jungle fowl, forma domestica) of both sexes was studied to determine sex variations in structures. Ten (10) birds, involving 5 males and 5 females were obtained from a local market for student demonstrations and used for this study. Tracheal rings were observed to be made of circular cartilages numbering thirty and above with the distal most (1/5) tracheal rings narrowed, calcified and fused as the tympanum making part of the Syrinx. The rings become calcified and somewhat collapsed through the bronchial bifurcations. When squeezed, the trachea collapsed completely between fingers but could at releasing the fingers be raised up due to elastic components separating the rings from one another. Other structures involved in vocalization includes straps of muscles. Male structures involved in respiration and vocalization were well formed compared to those of the female. Both tracheobronchialis lateralis and ventralis muscles were thicker than those of the female. Male tracheobronchialis ventralis and dorsalis muscles were well formed and spindle shaped. However, the female tracheobronchialis muscles were seen to be wider compared to the male. The vocal organs (voice box) were seen to be arbitrarily triangular in structure at the bifurcation of the trachea in both sexes. The male Syringeal walls were thinner and were seen to have marked inter Pessula space. The Pessulus mark an abrupt change from the circular trachea to strongly elliptical entrances to the bronchi. It was concluded that the differences in the thinness of syringeal walls coupled with differences between the males and females in other tracheal muscles might be responsible for the stronger vocalization in the male.

Abstract The Atlantic Forest is considered a biodiversity hotspot because of its exceptional species richness, endemism, and habitat losses. Commercial logging, industrial forestry, and agriculture represent threats to the Atlantic Forest, and even though it has been protected by law since 2006, forest suppression continues and large volumes of Atlantic Forest wood are traded every year. To promote environmental conservation and prevent illegal logging, the verification of wood species’ identifications is fundamental throughout several stages of the wood supply chain by supervisory bodies, traders, and even consumers. Macroscopic wood anatomy analysis has been shown to be an efficient method for screening, although tools to streamline the efficiency of that process are necessary. We introduce here an interactive identification key for Atlantic Forest tree species, based on standard wood macroscopic features that is now available online at http://gbg.sites.uff.br/lamad/.
