“…A similar lignification process was also found in the fruit of wild roses (Rosa multiflora) during the period of fruit growth and development through anatomic study. The fruit of these five species were same as peach fruit, which contained endocarp, mesocarp, and exocarp (Guzicka et al, 2012). In addition, the data are from microarrays, hence not all the genes are necessarily on the array and, depending on the oligos used, they may not discriminate between the splice variants.…”

Lignin is one of the main components of plant cell walls, which provides mechanical support for plants and also contributes to resisting against plant pathogenic fungi. In the fruit industry, the lignin content can affect the quality of fruit. The biosynthesis of lignin involves a variety of enzymes, of which caffeoyl-CoA 3-O-methyltransferase (CCoAOMT) is a class of methyltransferases that plays an essential role in lignin biosynthesis. Studies have been conducted on the CCoAOMT gene family in several species, including arabidopsis (Arabidopsis thaliana), black poplar (Populus nigra), and cotton (Gossypium hirsutum). Still, there is relatively little research on this gene family in the Rosaceae. In this study, we used bioinformatics to identify and characterize the CCoAOMT gene family in apple (Malus domestica), chinese white pear (Pyrus bretschneideri), and peach (Prunus persica). In total, 35 CCoAOMT genes were identified in the three Rosaceae species: 8 from chinese white pear, 12 from apple, and 15 from peach. By using structure analysis and collinearity analysis, we found 12 conserved motifs and 12 pairs of CCoAOMT genes with collinearity. In the phylogenetic tree, the gene family was mainly divided into two groups. The genes had different expression patterns during the growth and development stage of fruit, a finding that is consistent with the pattern of lignin accumulation. This study will be beneficial for further study of CCoAOMT genes.

“…Thus, the detection of these birds is usually compromised, which leads to an underestimation of richness and abundance of species associated with higher forest strata (Walther, 2003;Derlindati and Caziani, 2005;Anderson, 2009). Studies that directly access canopy birds generally involve observations from towers placed at the height of emergent trees (Greenberg, 1981;Loiselle, 1988;Naka, 2004;Anderson and Naka, 2011), platforms (Bouricius et al, 2002;Peña-Foxon and Díaz, 2012) and walkways, where mist nets can also be employed (Rahman, 2002), or cranes with more sophisticated technology (Shaw, 2002).…”

Mist nets may be opened at different heights in the forest, but they are seldom used over 3 m above the ground. We used two different methods to compare species richness, composition, and relative abundance and trophic structure of the bird assemblage at Ilha Grande (with a 290 birds standardization): conventional ground-level nets (0-2.4 m height range) and elevated nets (0-17 m) with an adjustable-height system (modified from Humphrey et al., 1968) that we call vertically-mobile nets. There were significant differences in capture frequencies between methods for about 20% of the species (Chi-squared test, P<0.05), and the two methods caught different assemblages. Ground-level nets recorded less species, and they comparatively overestimated mainly Suboscine insectivores and underestimated frugivores and nectarivores. Different sampling methods used at the same location may result in very different diagnoses of the avifauna present, both qualitatively and quantitatively. We encourage studies involving mist net sampling to include the upper strata to more accurately represent the avifauna in Atlantic Forest.Keywords: canopy, high nets, mist net sampling, trophic structure, vertical stratification. Assembleia de aves capturadas em redes de neblina em uma área de MataAtlântica: uma comparação entre redes verticalmente móveis e no nível do solo ResumoRedes-de-neblina podem ser abertas a diferentes alturas na floresta, mas raramente são usadas acima de 3 m do chão. Usamos dois diferentes métodos para comparar riqueza, abundância relativa de espécies e estrutura trófica da assembleia de aves da Ilha Grande (com a padronização de 290 indivíduos): redes convencionais no nível do solo (0-2,4 m de altura) e redes bandeira (0-17 m) com um sistema de ajuste de altura (modificado de Humphrey et al., 1968) que denominamos redes verticalmente móveis. Houve diferenças significativas nas frequências de capturas entre os métodos em cerca de 20% das espécies (teste Qui-quadrado, P<0,05), e os dois métodos capturaram diferentes assembleias. Redes de neblina no nível do solo registraram menos espécies, e comparativamente superestimaram principalmente espécies insetívoras de Suboscine, e subestimaram frugívoras e nectarívoras. Métodos diferentes de amostragem usados em uma mesma localidade podem resultar em uma diagnose bem distinta da avifauna presente, tanto qualitativa como quantitativamente. Recomendamos que estudos envolvendo amostragens com redes-de-neblina incluam os estratos superiores para representar mais acuradamente a avifauna na Mata Atlântica.Palavras-chave: dossel, redes-bandeira, amostragem com redes-de-neblina, estrutura trófica, estratificação vertical.

Summary1. The availability of reliable information on tree climbing methods is critical for the development of canopy science and for the safety of workers accessing the forest canopy. 2. To assess the breadth and quality of information contained in published climbing information, we performed searches in Web of Science and Google Scholar and evaluated 54 published sources on 10 predetermined criteria related to safety. 3. We found a high incidence of unsafe recommendations that, if followed, could result in serious injury or death. Common errors included recommendations for equipment not suitable for tree climbing, advocating methods suitable for rock climbing but that can result in falls and trauma in tree climbing, and outdated information that no longer reflects best practices. 4. We conclude by providing safety recommendations and a short review of tree climbing methods. This article thus serves as a guide for finding and interpreting best sources of methods for canopy access.
