Lignin composition is related to xylem embolism resistance and leaf life span in trees in a tropical semiarid climate.
The monomeric composition of lignin (S : G) is therefore an important functional wood attribute affecting several key functional aspects of tropical tree species in a semiarid climate. Expand
The parasitoid wasp Eruga unilabiana Pádua & Sobczak, sp. nov. (Hymenoptera: Ichneumonidae) induces behavioral modification in its spider host
This study investigated the wasp's host selection, development, and manipulation of host behavior, and found that most of the parasitized spiders were intermediate‐sized adult females that probably provide sufficient resources for parasitoid larvae and are less vulnerable for parasitized females than larger host individuals at attack.

A New Record of a Host-Parasitoid Interaction: Hymenoepimecis veranii Lofredo & Penteado-Dias, 2009 (Hymenoptera: Ichneumonidae) Parasitizing Araneus orgaos Levi, 1991 (Araneae: Araneidae)
This study provides detailed information about the natural history of the host-parasitoid interaction involving this wasp with a new host, the spider Araneus orgaos (Araneae: Araneidae), which occurs sympatrically with A. omnicolor. Expand
First record of epicadus trituberculatus (Taczanowski, 1872) (araneae, thomisidae, stephanopinae) in the Brazilian Northeast
We present the first record of Epicadus trituberculatus (Taczanowski, 1872) from the Northeast Region of Brazil. The new record is based on six specimens observed in two areas of montaneExpand
Behavioral manipulation of the spider Macrophyes pacoti (Araneae: Anyphaenidae) by the araneopathogenic fungus Gibellula sp. (Hypocreales: Cordycipitaceae)
Host manipulation has already been documented in several distinct host-parasite associations, covering all major phyla of living organisms, and in animals several species have the ability to manipulate their environment. Expand
First record of Anelosimus jucundus (O. Pickard-Cambridge, 1896) (Araneae, Theridiidae) in the state of Ceará, Brazil
Anelosimus jucundus presents a wide altitudinal distribution, which indicates that this species can tolerate a variety climatic conditions and can colonize a variety of sites with different vegetation. Expand
