Constituintes químicos voláteis e não-voláteis de Cochlospermum vitifolium (Willdenow) Sprengel [PDF]
Quimica Nova, 2005 The essential oils from leaves, root bark and root wood of Cochlospermum vitifolium were investigated for the first time. The oils were obtained by hydrodistillation and analyzed by GC/MS. The main volatile constituents were b-caryophyllene (8.2 - 46.5%), b-bisabolene (11.5 - 29.3%), g-muurolene (28.4%), a-humulene (26.0%), 1-hydroxy-3-hexadecanone (16.

Osmoxylon-like fossils from early Eocene South America: West Gondwana-Malesia connections in Araliaceae. [PDF]
Am J BotAbstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Picking pithy plants: Pith selectivity by wild white-faced capuchin monkeys, Cebus imitator. [PDF]
Am J Primatol“When and why do white‐faced capuchins eat plant pith? We investigated how ecological variables and plant traits shape patterns of pith consumption. We find that pith foraging occurs primarily during seasonal transitions, and that dietary pith species contain relatively more pith, are softer, and have a different odor profile than non‐dietary species.“

Modeling the current and future habitat suitability of Neltuma pallida in the dry forest of northern Peru under climate change scenarios to 2100. [PDF]
Ecol EvolThe objective of this research was to evaluate the current and future distribution and conservation status of Neltuma pallida in the Peruvian dry forest under climate change scenarios over the last few years. The findings indicated that the likely range of habitats for N. pallida was shaped by factors such as the average temperature of wettest quarter,

Do soil microbes and abrasion by soil particles influence persistence and loss of physical dormancy in seeds of tropical pioneers? [PDF]
Frontiers in Plant Science, 2015 Germination from the soil seed bank (SSB) is an important determinant of species composition in tropical forest gaps, with seed persistence in the SSB allowing trees to recruit even decades after dispersal.

Howler monkey foraging ecology suggests convergent evolution of routine trichromacy as an adaptation for folivory. [PDF]
Ecol Evol, 2017 Primates possess remarkably variable color vision, and the ecological and social factors shaping this variation remain heavily debated. Here, we examine opsin genes, feeding behaviors, and reflectance of dietary foliage of wild mantled howler monkeys (Alouatta palliata).

Complement activation and inhibition in wound healing. [PDF]
Clin Dev Immunol, 2012 Complement activation is needed to restore tissue injury; however, inappropriate activation of complement, as seen in chronic wounds can cause cell death and enhance inflammation, thus contributing to further injury and impaired wound healing. Therefore, attenuation of complement activation by specific inhibitors is considered as an innovative wound ...

Medicinal Plants for the Treatment of Local Tissue Damage Induced by Snake Venoms: An Overview from Traditional Use to Pharmacological Evidence. [PDF]
Evid Based Complement Alternat Med, 2017 Snakebites are a serious problem in public health due to their high morbimortality. Most of snake venoms produce intense local tissue damage, which could lead to temporary or permanent disability in victims. The available specific treatment is the antivenom serum therapy, whose effectiveness is reduced against these effects.
