Additional data on the synlophe and morphological measurements are provided for the heligmonellids Stilestrongylus aculeata (Travassos, 1918) and Stilestrongylus eta (Travassos, 1937), collected from Akodon montensis Thomas, 1913, of the Atlantic Forest, Rio de Janeiro, Brazil. The synlophe of S. aculeata is characterized by 19 cuticular middle body ridges in males and 24 cuticular middle body ...

Lichen symbioses were recently shown to include diverse bacterial communities. Although the biogeography of lichen species is fairly well known, the patterns of their bacterial associates are relatively poorly understood. Here we analyse the composition of Alphaproteobacteria in Cetraria aculeata, a common lichen species that occurs at high latitudes and various habitats. Using clone libraries ...

Improper tillage with no manure may cause a range of undesirable processes (destruction of soil structure, accelerate erosion, depletion of organic matter and fertility). A field experiment was conducted to observe the change in soil properties after incorporation of green manure crops and to find out the residual effect of green manure crops along with tillage on maize and rice yields during 2...

Early embryogenesis has been examined experimentally in several echinoderm and hemichordate classes. Although these studies suggest that the mechanisms which underlie regional specification have been highly conserved within the echinoderm + hemichordate clade, nothing is known about these mechanisms in several other echinoderm classes, including the Ophiuroidea. In this study, early embryogenes...

Acrocomia aculeata is a perennial, fruit-producing palm tree, native to tropical forests. Its fruits have spurred interest because of their significant potential for use in the cosmetic industry and as feedstock for biofuel. In the present study, the genetic structure and mating system in Acrocomia aculeata were analyzed, using eight nuclear micro-satellite loci and samples from São Paulo and M...

production of reactive oxygen species (ROS) and their removal, has been implicated in the progression of many neurodegenerative diseases including Alzheimer’s disease (AD) and stroke. Inflammation is characteristic of brain tissue, pathologically affected by neurological diseases such as AD and Parkinson’s disease. Cognitive deficits due to aging and AD are related to the increased vulnerabilit...

PREMISE OF THE STUDY Polymorphic microsatellite markers were developed for the lichen species Cetraria aculeata (Parmeliaceae) to study fine-scale population diversity and phylogeographic structure. METHODS AND RESULTS Using Illumina HiSeq and MiSeq, 15 fungus-specific microsatellite markers were developed and tested on 81 specimens from four populations from Spain. The number of alleles rang...

Macaw palm (Acrocomia aculeata) is native to tropical forests in South America and highly abundant in Brazil. It is cited as a highly productive oleaginous palm tree presenting high potential for biodiesel production. The aim of this work was to characterize and study the genetic diversity of A. aculeata ex situ collections from different geographical states in Brazil using microsatellite (Simp...

As part of efforts to identify native herbivores of Mexican palo verde, Parkinsonia aculeata L. (Leguminosae: Caesalpinioideae), as potential biological control agents against this invasive weed in Australia, ten species of Tortricidae (Lepidoptera) were reared from Guatemala, Mexico, Nicaragua, and Venezuela: Amorbia concavana (Zeller), Platynota rostrana (Walker), Platynota helianthes (Meyric...

Pereskia aculeata Miller commonly known as “ora-pro-nobis” has been used extensively in folclore medicine. Plant belongs to the family Cactacea and it is found in the Brazil (reaching Bahia and Rio Grande do Sul states). The purpose was to evaluate the effects of plant on biochemical and corporal profiles of Wistar rats. The 80 animals were divided randomly into 4 groups by sex (n = 10 females ...
