Agricultural production on acid soils is compromised by aluminum (Al) toxicity, which damages the root system leading to mineral nutrient deficiency and enhanced drought stress. Considering that approximately 50% of the ...

The giant cicada Quesada gigas (Olivier, 1790) (Hemiptera: Cicadidae) is a major pest of coffee plants in Brazil. To ensure the rational management and ecological equilibrium, information about the behavior, dispersion, ...

Homoploid speciation generates species without a change in chromosome number via introgressive hybridization and has been considered rare in animals. Heliconius butterflies exhibit bright aposematic color patterns that ...

The production of spermatophore and ejaculate is energetically expensive for males. High mating rates may accelerate sperm depletion and progressively decrease the size of the ejaculates. Sperm competition can shape ...

We present the molecular characterization of a new virus infecting yerba mate (Ilex paraguariensis St. Hil.) in Argentina. Deep sequencing of diseased yerba mate plants showing chlorotic linear patterns, chlorotic rings, ...

Worldwide, the significant fragmentation of tropical forests has resulted in the isolation of tree populations; this in turn has affected genetic diversity due to increases in inbreeding, leading to inbreeding depression ...

Premise of the study: Tropical forest loss and fragmentation isolate and reduce the size of remnant populations with negative consequences for mating patterns and genetic structure of plant species. In a four year study, ...

Polygynous males increase their reproductive success by fertilizing as many females as possible. However, this strategy can lead to costs for the males. This study focused on an atypical wolf spider that lives in webs, ...
