The behavior of covering eggs with debris has been previously described for several harvestman species of the families Cosmetidae and Gonyleptidae that present no care or exclusive maternal care (references in Willemart 2001).
Effects of maternal care on the lifetime reproductive success of females in a neotropical harvestman.
2005) found that the composition of the secretions in the two species studied by them was highly consistent from individual to individual within species, as has been reported in numerous previous studies of harvestman defensive secretions.
In addition, no study has yet been made of the effect of collection method on the results of the analysis of harvestman secretions.
The most comprehensive study on seasonal changes in harvestman
behavior has been conducted by Gnaspini et al.
However, small-ranged endemics should not be seen as the rule for harvestman
The application of broad-spectrum insecticides in apple orchards significantly decreased spider and harvestman
populations (Epstein et al.
cardoso may avoid competition with and/or predation by females of the harvestman
Bourguyia albiornata Mello-Leitao 1923, which frequently use A.
From 9 July-3 August 2005, we made observations of parental care by adults of the Neotropical cranaid harvestman
Phareicranaus calcariferus (Simon 1879) in northern and central Trinidad.
Therefore, the behavioral pattern of oviposition described for the New Zealand Soerensenellinae contrasts with all other harvestman
species that present maternal care and is remarkably similar to the species that present paternal care (see Machado et al.
Skeletomuscular anatomy of the harvestman
Leiobunum aldrichi (Weed, 1893) (Arachnida: Opiliones) and its evolutionary significance.
Field observations suggested that the spider Enoploctenus cyclothorax (Bertkau 1880) avoids preying on the harvestman
Mischonyx cuspidatus (Roewer 1913).
