    Abstract The leaves and ramicaules of 16 epiphytic species from the genera Acianthera, Anathallis, and Specklinia belonging to the subtribe Pleurothallidinae were analyzed anatomically in order to find useful traits for the distinction of genera and species. The present study reveals that the leaves of Pleurothallidinae species possess anatomical characteristics such as trichomes, vascular bundles, and idioblasts, which are valuable for distinguishing such genera. We also found that leaf characteristics, such as the shape of epidermal cells, margin type, cuticle ornamentation, hypodermis, and presence of idioblasts, in conjunction with characteristics of the ramicaule, such as cross-section shape and cell type of the external cortex, can be used to distinguish species. A key to the genera based on data is provided and some characteristics are discussed regarding epiphytism.

    Abstract Pleurothallidinae is the largest Orchidaceae subtribe of the Neotropics, with most of its diversity composed of epiphytes from wet forests. Recent classifications still do not have sufficient micromorphological support, and genera delimitation is unclear. Here, we provide a structural analysis of the root anatomy in 55 species and 10 genera of Brazilian Pleurothallidinae and phylogenetic analysis based on ITS and MatK sequences available in databases. All roots are velamentous, with 2–6 layers of epidermal tissue. In the cortex, chloroplasts, amyloplasts, fungal pelotons, idioblasts with raphides, and tracheoid idioblasts are frequent. Exodermis and endodermis cells may be thickened in different patterns, with thin-walled passage cells. We identified four different clades: clade A (Octomeria species, ancestor with a two-layered velamen, without tilosomes, U-thickened exodermis, and sclerified pith), clade B (Echinosepala and Myoxanthus, ancestor with three or more layers in the velamen, without tilosomes, more than five layers of cortical parenchyma, pith with amyloplast), Clade C (Anathallis, Masdevallia, Pabstiella, Specklinia, Stelis, and Zootrophion; ancestor with two-layered velamen, with tilosomes, thin-walled exodermis, sclerified pith), and clade D (Acianthera, ancestor with two-layered velamen, without tilosomes, O-thickened exodermis, up to five layers of cortical parenchyma, sclerified pith). The traits cited for these clades are not necessarily apomorphies and may have been lost in some of the subclades. However, it indicates the ancestral characteristics of the group and can contribute to its systematics. The relationships in Pleurothallidinae and its large number of species require multidisciplinary attention to the group to better understand the group's evolution, including more structural analyses like this study.

    Abstract Coastal dune is a habitat that presents determining and often limiting factors for plant development. Species of Asteraceae, such as Mikania cordifolia, are commonly found in this environment, including occupying frontal dunes, where winds, salinity, and soil represent severe environmental conditions. Asteraceae is recognized for its different secretory structures and for containing species with potential for bioprospecting. Mikania cordifolia is a species with a voluble habit, wide geographic distribution, and records of medicinal use. However, no studies in the literature cover the anatomical, histochemical, and chemical investigation of all vegetative organs of the mentioned species. In this sense, this study evaluated the anatomical organization of the vegetative organs of M. cordifolia, including secretory structures, as well as the chemical composition of the extract of each organ. For this, diaphanization, microtomy, histochemistry, and phytochemistry techniques were used. Our results showed that the vegetative organs have several adaptations to the coastal dunes environmental conditions, among them the presence of four types of secretory structures – secretory canals and cavities, trichomes and hydathodes. Histochemical analyzes indicated sesquiterpene lactones, pectic and phenolic compounds, lipophilic substances, flavonoids, coumarins, starch and tannins. Nuclear magnetic resonance analyzes showed kaurane diterpenes, steroids, fatty acids, phenolic derivatives, and methoxylated substances. Our results contribute to the understanding of the structure and phytochemistry of the genus Mikania, the adaptations of the species to the coastal dune environment, and the occurrence and distribution of secretory structures in the genus, promoting knowledge and justifying the conservation of the coastal dunes flora.

    Abstract Varronia polycephala is a medicinal plant used as a substitute of V. curassavica (the popular “erva baleeira”) in some traditional communities. This paper aims to describe and illustrate the leaf anatomy of V. polycephala. The results show that V. polycephala presents a distinct type of non-glandular trichome in abundance on the abaxial leaf surface, as well as a single type of glandular trichome on the same surface. Other characteristics observed in V. polycephala include non-glandular trichomes with cystoliths, crystal sand idioblasts, shape of the petiole in cross section, type of vascular bundles and ring collenchyma in the petiole. Histochemical results suggest similarities with V. curassavica, showing the pharmacological potential of V. polycephala. Possible ecological functions of structures and substances are discussed.

    Abstract In this study, we performed a detailed anatomical analysis of the androecium and gynoecium in 16 species belonging to three out of the eight Bromeliaceae subfamilies, with a first-time description of the interlocular zone in anthers, a diagnostic character for Quesnelia and Aechmea species. Other potential taxonomic characters were observed: protuberances formed by growth in the connective region of anthers, which only occurs in species belonging to the Nidularioid complex; and an endothecium-like tissue in the anthers, near to the connective region, characterizing Dyckia species. Besides these characters, the vascularization of filaments and style are discussed from a phylogenetic perspective. In that sense, the vascularization of style is supplied by three vascular bundles that may represent a synapomorphy for Pitcairnoideae and should be further investigated in the family. In addition, the vertical zonality of carpels is described for analyzed inferior and superior ovaries and the position of the nectaries is discussed in this context. Regarding the secretory structures present on the gynoecium we provided novel data for future evolutionary studies on this group. Furthermore, characters presented in this study are discussed from an ecological point of view.

    Abstract The design of products for people with disabilities requires the understanding of a wide range of factors related to users' health, functional abilities, needs, expectations and preferences. Such multifactorial perspective is often perceived as beyond the reach by the students of both graphic and product design, as it comprises knowledge from different areas such are not usually part of design curriculum as health, rehabilitation, computer science and biomedical engineering. Here, we report on strategies for developing design students' empathy and awareness for the needs and expectations of people with disabilities. By means of a combination of theoretical and practical approaches, a course on Inclusive Design was developed as part of the regular curriculum of the Bachelor Programme in Design at Sao Paulo State University (UNESP, Bauru campus, Brazil), with the collaborative participation of members of SORRI BAURU Rehabilitation Center. The final projects developed by the students were based on the demands presented by SORRI BAURU's rehabilitation team, and results reveal that the theoretical-practical approach based on interdisciplinarity was shown to provide the design students a learning experience that, ultimately, supports the quality decision-making in the design process. This paper describes the pedagogical approach, theoretical contents and practical activities developed during the Inclusive Design course. The challenges, benefits, results, and contributions of this experience from the perspective of the design education are also discussed.

    Abstract The objective of this study was to evaluate the environmental effects on embryo recovery rate and pregnancy rate of Mangalarga Marchador mares. The reproductive characteristics of donor and recipient mares were evaluated during five years in Brazilian tropical environment. The mares were used throughout the year and seasons were classified as: October to April (breeding season - BS); May (autumn transition out of the breeding season - ATBS); June to August (non-breeding season - nBS); and September (vernal transition into the breeding season - VTBS). Daily temperature rainfall and hours of daylight (photoperiod) were measured during all months and years of evaluation. The embryo recovery rate (ERR) and the pregnancy rate (PR) were observed and frequencies were calculated. The effect of environmental variables, day of flushing, and hormonal treatments (estradiol benzoate and progesterone) were determined for the reproductive measures using the Chi-square and Kruskal-Wallis tests. Significant effects were noted of the year, season and temperature on ERR (P < 0.05), but no significant effects were observed of the environmental parameters (year, season, hormone treatment, rainfall and photoperiod) on PR (P > 0.05). The day of uterine flush affected ERR (P < 0.05) but did not affect PR (P > 0.05). In addition, hormone treatment also supported favorable results of PR in recipient mares during nBS. The conclusion is that mares of this breed can be used in reproduction all year long, with good pregnancy rates, in Brazil's tropical environment. The hormone treatment also supported favorable pregnancy rates in recipient mares during the non-breeding season. It seems that mares can have good pregnancy rates throughout the year in Brazil´s tropical environment.
