“…Kim [57] suggested that group molting among colonial spiders is an adaptation that maintains a similar size among all individuals, which helps to reduce cannibalism during the molting period. This could indeed be an explanation for the case of the supposed synchronized molting in the new megacheiran, as megacheirans are also interpreted as predators [2,3,58].…”

BackgroundThe Burgess Shale is well known for its preservation of a diverse soft-bodied biota dating from the Cambrian period (Series 3, Stage 5). While previous paleoecological studies have focused on particular species (autecology) or entire paleocommunities (synecology), studies on the ecology of populations (demecology) of Burgess Shale organisms have remained mainly anecdotal.ResultsHere, we present evidence for mass molting events in two unrelated arthropods from the Burgess Shale Walcott Quarry, Canadaspis perfecta and a megacheiran referred to as Alalcomenaeus sp.ConclusionsThese findings suggest that the triggers for such supposed synchronized molting appeared early on during the Cambrian radiation, and synchronized molting in the Cambrian may have had similar functions in the past as it does today. In addition, the finding of numerous juvenile Alalcomenaeus sp. molts associated with the putative alga Dictyophycus suggests a possible nursery habitat. In this nursery habitat a population of this animal might have found a more protected environment in which to spend critical developmental phases, as do many modern species today.

“…Maternal care in this sub-social species is highly complex, where the mother produces trophic eggs for her spiderlings ( Kim & Roland, 2000 ), with spiderlings and their mother practising matriphagy ( Kim & Horel, 1998 ). The young sub-social spiders also cooperate in prey capture ( Kim et al , 2005 ), and synchronise their development ( Kim, 2001 ).…”

“…Cooperation, a behavioural strategy in which agents achieve a common goal through coordinated action (1), has been investigated in a variety of animal species ranging from mammals (2)(3)(4)(5) and birds (6) to social arthropods (7)(8)(9). Some experimental paradigms have been particularly popular to investigate cooperation [reviewed in (10)], such as the "string pulling task" (or "loose-string paradigm") employed in more than 160 bird and mammal species (11).…”

The Joint Log-Lift Task: A Social Foraging Paradigm

et al. 2021

Behavioural cooperation is under intense research. Yet, popular experimental paradigms often employ artificial tasks, require training, or do not permit partner choice, possibly limiting their biological relevance. We developed the joint log-lift task, a social foraging paradigm in which animals have to jointly lift a log to each obtain a food reward. The task relies on an obligate strategy, meaning that the only way to benefit is to work jointly. We hypothesised that (1) animals learn to spontaneously solve the task, and that (2) kin and (3) more sociable individuals would engage more often together in the task and achieve greater success than non-kin and less sociable individuals, respectively. We presented the task to 8 groups of juvenile domestic pigs (Sus scrofa domesticus) in their home pen for 30 min daily. Over the course of 9 days, the pigs showed evidence of learning by progressively switching from individual to joint behaviours, leading to 68% (62 out of 91 pigs) spontaneously solving the task. Success was influenced by sociability, but not kinship. There were large differences in success among dyads, hinting at the possible role of social dynamics and inter-individual differences in the ability and/or motivation to solve the task. The joint log-lift task allows researchers to investigate spontaneous cooperative tendencies of individuals, dyads and groups in the home environment through ad libitum engagement with the apparatus. This ecologically relevant paradigm opens the way to investigate social foraging experimentally at large scale, by giving animals free choice about when and with whom to work jointly.
