“…Laboratory experiments have shown that individual behaviour underlying group coordination can evolve in just a few generations [47,48]; however, such changes have yet to be documented in the field. Species invasions provide opportunities to observe evolutionary changes in behaviour [49,50]. In our study of an invasive population, we found less stable tandem runs than those previously observed in a native population of C. formosanus in Japan [19] (electronic supplementary material, figure S4).…”

Coordination of movement via complementary interactions of leaders and followers in termite mating pairs

In collective animal motion, coordination is often achieved by feedback between leaders and followers. For stable coordination, a leader's signals and a follower's responses are hypothesized to be attuned to each other. However, their roles are difficult to disentangle in species with highly coordinated movements, hiding potential diversity of behavioural mechanisms for collective behaviour. Here, we show that two Coptotermes termite species achieve a similar level of coordination via distinct sets of complementary leader–follower interactions. Even though C. gestroi females produce less pheromone than C. formosanus , tandem runs of both species were stable. Heterospecific pairs with C. gestroi males were also stable, but not those with C. formosanus males. We attributed this to the males' adaptation to the conspecific females; C. gestroi males have a unique capacity to follow females with small amounts of pheromone, while C. formosanus males reject C. gestroi females as unsuitable but are competitive over females with large amounts of pheromone. An information-theoretic analysis supported this conclusion by detecting information flow from female to male only in stable tandems. Our study highlights cryptic interspecific variation in movement coordination, a source of novelty for the evolution of social interactions.

Leadership of animal group movements depends on social feedback, hence leader′s signals and follower′s responses should be attuned to each other. However, leader and follower roles are difficult to disentangle in species with high levels of coordination. To overcome this challenge, we investigated a simple case of movement coordination: termite pairs in which a female leads a male as they search for a nest site. To tease apart leader and follower roles, we created conspecific and heterospecific pairs of Coptotermes gestroi and C. formosanus, which share a pairing pheromone so that males follow females of either species. Conspecific pairs were stable for both species, even though C. gestroi females produce less pheromone than C. formosanus. Heterospecific pairs with C. gestroi males were also stable, but not those with C. formosanus males. We attributed this difference to the C. gestroi male′s unique capacity to follow females that release small amounts of pheromone; C. formosanus males cannot follow or reject C. gestroi females as unsuitable. This conclusion was supported by an information-theoretic analysis that detected information flow from C. formosanus females to C. gestroi males as in conspecific pairs, but not from C. gestroi females to C. formosanus males. Despite their following ability, C. gestroi males lost to C. formosanus males in competitions to follow C. formosanus females. Thus, partner selection has shaped the species-specific association of mating pairs. Our results demonstrate that a similar level of coordination can emerge from distinct sets of complementary sender-receiver interactions.

“…The prey naïveté hypothesis predicts that native prey often fail to recognize and/or avoid an introduced predator due to a lack of the coevolutionary history (Cox & Lima, 2006;Sih et al, 2010). Similarly, but in a different scenario where introduced species are prey for local predators, lack of native predator recognition by invasive prey can result in increased predation on the introduced species (e.g., Barrio et al, 2010;Carthey & Banks, 2018;Ruland & Jeschke, 2020). We observed that M. trilobatus frequently abandoned their webs after the predators' intrusion, and once outside their webs were easily subdued by Pachygnatha.…”

Nonindigenous species can play influential roles in their exotic range once becoming invasive. Invasions are considered successful when alien species establish and rapidly expand their ranges in novel environments by overcoming biogeographical barriers and ecological pressures (Sakai et al., 2001). The impact of invasive species on native ecosystems has been described since the middle of the 20th century (Elton, 1958). However, the mechanisms behind the often striking success of invasive species are still uncertain (Schultheis et al., 2015). Up to 39 hypotheses were developed to better describe the processes behind successful invasions (Enders et al., 2019). As one of the most predominant and intuitive, the enemy release hypothesis posits that nonindigenous species are released from the pressure of predators and parasites once introduced to their exotic ranges (Elton, 1958;Keane & Crawley, 2002).
