The Scent Glands of the Neotropical Harvestman Discocyrtus pectnifemur: Morphology, Behavior and Chemistry
TLDR
The morphology of the ozopore area, the mode of emission of the defensive secretion, and its chemical composition in the harvestman Discocyrtus pectinifemur are described, and they suggest that the alarm pheromone function in harvestmen may be dependent on ecological factors.
Delicate fangs, smart killing: the predation strategy of the recluse spider
TLDR
This study is the first to document and describe how recluse spiders overcome the defences of an armoured harvestman and quantitatively described the spider's behaviour.
Defences of a Neotropical harvestman against different levels of threat by the recluse spider
TLDR
Surprisingly, their mostly known defensive behaviours (chemical defence, tanathosis, pinching with chelicerae and pedipalps) were not seen even in the high threat situation.
Sexual differences in weaponry and defensive behavior in a neotropical harvestman
TLDR
Evidence is provided that due to sexual dimorphism, alternative antipredatory behaviors may have been selected in the different sexes in M. cuspidatus.
Starvation decreases behavioral consistency in a Neotropical harvestman
TLDR
It is found that individuals showed more consistency in boldness when sated relative to a food-deprived condition, and new avenues for future studies addressing personality in harvestmen are suggested.
Predatory behavior and sensory morphology of the whip spider Charinus asturius (Arachnida: Amblypygi)
TLDR
This study described the sensory morphology of the antenniform leg and the predatory behavior of Charinus asturius Pinto-da-Rocha, Machado and Weygoldt, 2002, a representative of the family Charinidae and reports the presence of most sensilla types described in the better studied Phrynidae and highlights novel aspects such as the morphology ofthe tarsal organ and the reduced number of rod sensilla.
On the habitat use of the Neotropical whip spider Charinus asturius (Arachnida: Amblypygi)
TLDR
The habitat use by Charinus asturius Pinto-da-Rocha, Machado & Weygoldt, 2002, an endemic species of Ilhabela Island in Brazil is investigated and it is found that C.Asturius is more likely to be found under rocks that cover larger areas of substrate.
Relationship between model noxiousness and mimetic accuracy in myrmecomorphic spiders
TLDR
A tests the relaxed selection hypothesis, which postulates that the level of mimetic resemblance avoided by predators is context-dependent, and finds a negative correlation between model noxiousness and mimetic accuracy.
