The evolutionary history of vertebrate locomotion is punctuated by innovations that have permitted expansion into novel ecological niches. Frictional adhesion of geckos is an innovation renowned for enabling locomotion on vertical and inverted smooth surfaces. Much is known about the microstructure and function of the fullyexpressed gekkotan adhesive apparatus, although how it originated is poo...

The closure of two phases of the dam at the Porto Primavera Hydroelectric Plant on the Paraná River flooded a flawed system located in the Municipality of Presidente Epitácio, São Paulo state, favoring the proliferation of aquatic weeds. This study aimed to observe the population of Mansonia humeralis in the area, monitoring the richness, diversity, and dominance of this species both before and...

A comparative study of serum biochemical and hematological parameters from Andinoacara rivulatus Ichthyoelephas humeralis in Los Ríos Province, Ecuador, was carried out. Two the native species that are most commercialized Quevedo, Mocache Fumisa, were identified; 60 specimens captured each area (180 total). factorial design (3×2) used: three habitat zones (Fumisa, Mocache) two (A. I. humeralis)...

Environ Entomol 23(6): 1534-1543 (1994) ABSTRACT The nitidulid species, Carpophilus mutilatus Erichson, C hemipterus (L ), C freemani Dobsan, and C obsoletus Erichson, responded to their aggregation pheromones during a 17-mo study in a California date garden The pheromones were dramatically synergized by volatiles from fermenting whole-wheat bread dough; pheromones alone attracted only 1 0-29% ...

Two species of Geotrupidae, Geotrupes splendidus splendidus (Fabricius) and Odonteus liebecki (Wallis), are newly reported for New Brunswick, Canada. Twelve species of Scarabaeidae are added to the faunal list of the province, including Aegialia criddlei Brown, Caelius humeralis (Brown), Dialytellus dialytoides (Fall), Diapterna omissa (LeConte), Diapterna pinguis (Haldeman), Planolinoides aeni...

Thirty-three taxa associated with Ips typographus were identified, of which fifteen species were phoretic. The most abundant species were Insectolaelaps quadrisetus (Mesostigmata), Siculobata lentonycha (Oribata), Diapterobates humeralis (Oribata), Ereynetes propescutulis (Prostigmata), Aetiopltenax ipidarius (Prostigmata), and an unidentified species of Nanacarus (Astigmata). Eight species -I....

The Thamnophilidae is a diverse radiation of insectivorous passerine birds that comprises nearly 220 species and is mostly restricted to the lowlands and lower montane forests of the Neotropics. Current classification within Thamnophilidae relies primarily on morphological variation, but recent incorporation of molecular and vocal data has promoted changes at various taxonomic levels. Here we d...
