Variations in diel activity among hyperdiverse tropical communities of moths, despite representing a key component of niche partitioning between species, have barely been studied so far. Using light trapping from dawn to ...

Co-cultivation of the fungal strains Penicillium sp. Ma(M3)V and Trichoderma sp. Gc(M2)1 in malt 2% medium led to the production of two novel, unusual polyketides, (Z)-2-ethylhex-2-enedioic acid and (E)-4-oxo-2-propylide ...

This study performed the ultra-structural analysis of the changes caused by permethrin in the synganglion of semi-engorged Rhipicephalus sanguineus females, aiming to understand the toxic action of this substance at cellular ...

Mutualistic interactions involving pollination and ant-plant mutualistic networks typically feature tightly linked species grouped in modules. However, such modularity is infrequent in seed dispersal networks, presumably ...

This study establishes the presence of spermatodesm in the seminal vesicles of sexually mature males of Crematogaster victima (Smith). In this species, the spermatozoa are maintained together by an extracellular matrix in ...

Minimum post-mortem intervals can be estimated based on analyses of the pattern of insect succession on a carcass. In order to successfully apply this approach, insect development rates must be considered with regard to ...

The State of São Paulo is the most developed area in Brazil and was impacted by persistent organic pollutants for several decades. This study investigated organochlorines in five species of small cetaceans (Pontoporia ...

The adipose fin is small, nonpared, and usually located medially between the dorsal and caudal fin. Its taxonomic occurrence is very restrict; thus, it represents an important trace for taxon distinction. As it does not ...

Aim: The purpose of this study was to determine the presence of depressive symptoms in patients with Alzheimer's disease, to assess whether there was an association between physical activity level and depressive symptoms ...
