First documented cases of invertebrate predation by greater grisons (Galictis vittata)

  First documented cases of invertebrate predation by greater grisons (Galictis vittata) Abstract  We report the first documented predation of invertebrates by greater grisons (Galictis vittata) based on camera-trap footage from a mineral lick in Southeastern Peru. Two adult individuals were recorded capturing and consuming large arachnids, likely whip spiders (Amblypygi), from a natural cavity. One grison visibly removed and discarded part of the prey prior to ingestion, suggesting selective handling to reduce risk from defensive structures. These observations extend the known cavity-focused foraging behavior of G. vittata and indicate that amblypygids may represent an underreported but regular prey item in tropical habitats.

Intraguild predation by two species of Hottentotta (Scorpiones: Buthidae) in Pakistan

 


Intraguild predation by two species of Hottentotta (Scorpiones: Buthidae) in Pakistan



Abstract


Intraguild predation constitute an important ecological interaction in many ecosystems. We report two cases of intraguild predation involving scorpion as predator of centipede and assassin bug (Heteroptera: Reduviidae) during a nocturnal search for scorpions in Pakistan. In first case, Hottentotta jalalabadensis scorpion was found on rocks feeding a scolopendromorph centipede. On second, H. alticola individual was found with an assassin bug in their pedipalps and chelicerae also on rocks. In both cases when disturbed, the scorpion tries to flee to rock crevices without releasing its prey. To the best of our knowledge, this is the first report of intraguild interactions involving Pakistani scorpions. Depredación intragremial por dos especies de Hottentotta (Scorpiones: Buthidae) en Pakistán 


Resumen

La depredación intragremial constituye una importante interacción ecológica en muchos ecosistemas. Se reportan dos casos de depredación dentro de un gremio que involucran a escorpiones como depredadores de ciempiés y chinches asesinas (Heteroptera: Reduviidae) durante una búsqueda nocturna de escorpiones en Pakistán. En el primer caso, el escorpión Hottentotta jalalabadensis fue encontrado en las rocas alimentándose de un ciempiés escolopendromorfo. En segundo lugar, se encontró un individuo de H. alticola con una chinche asesina en sus pedipalpos y quelíceros, también en rocas. En ambos casos, cuando se sintió molestado, el escorpión intentó huir hacia las grietas de las rocas, sin soltar a su presa. Hasta donde sabemos, este es el primer informe de interacciones entre gremios que involucran escorpiones pakistaníes.
