“…Duetting can have several functions, some of which might even be present in one single species (Dahlin and Benedict, 2014). These are mate-guarding (Dowling and Webster, 2018;Dolotovskaya et al, 2020), to signify and or strengthen partnerships (Mèndez-Càrdenas and Zimmermann, 2009;Smith et al, 2010;Singletary and Tecot, 2020), and may serve as an indicator of the presence of a well-versed territorial defense team that may send a warning to potential intruders (Adret et al, 2018;Amorim et al, 2022). In sperm whales, Schulz et al (2008) studied the frequent exchanges of short sequences of clicks, termed codas.…”

Evolution of human language: duetting as part of prosociality and cognition

The evolution of human language is a topic that has received undiminished attention. Numerous hypotheses for the origin of human language have been proposed, including gestural communication found specifically among apes. This study advances the hypothesis that human evolution, including human language development, is three-pronged: prosocial, cognitive, and collaborative. Duetting and turn-taking in primates are used as pivotal examples of how bonding leads to joint action and collaboration. It points out that such vocal behavior itself may be a crucial precursor of language evolution in the sense that it is explicitly focused on a conspecific. Some current hypotheses have acknowledged duetting as an important perceptual and behavioral example of synchronicity. Some forms of synchronized behavior, as found in duetting, synchronized dance, or even shared song, were perhaps crucial evolutionary steps preceding the evolution of human language. Duetting signifies more than that, however, because it is an observable and significant cognitive investment that signals attention toward a partner. This study also advances the hypothesis that affect and cognition would have needed to precede any form of duetting or signs of affiliation such as grooming. Hence, this study, asking what duetting in primates signifies in evolutionary terms, takes a multidisciplinary and multimodal approach to suggest important affective and cognitive steps in the evolution of human language and speech, the chief of which is prosociality. Prosociality, as an attitude and awareness of another, be this as a friend or partner for whom one can do favors or whom one can help, is a model for collaboration and cooperation, and also increased cognition.

“…We used Google Earth ® to determine the maximum dispersal distance of the couple's new member from its previous nesting site whenever possible. We assume the nest site is located in the territory core (Fraga 1980, Amorim et al 2022).…”

“…These birds forage for arthropods on the ground and breed during austral spring (Fraga 1980, Diniz et al 2019), which coincides with the first half of the rainy season (França et al 2020) and the annual peak in arthropod abundance throughout its distribution (Silva et al 2011, Develey & Peres 2000). Partners coordinate territory defense by producing vocal duets nearby and chasing territorial intruders during both the breeding and non-breeding seasons (Diniz et al 2018, 2020, Amorim et al 2022). Partners also coordinate breeding activities and have similar parental efforts throughout the breeding stages (Massoni et al 2012).…”

The way an animal uses the home range and territory often vary in time according to its breeding state and habitat complexity. Adult dispersal can follow partner replacement, however little is known about seasonal/sex variation in partner replacement in tropical passerines. Here we tested if home range and territory size of the Rufous Hornero Furnarius rufus varies between the breeding and non-breeding seasons and if this variation is consistent across three distant populations in Brazil (UFJF, UnB, and MT). In addition, we described the frequency of partner replacements in relation to sex and breeding state in two of those populations (UFJF and UnB). We observed a decrease in 33% and 38% of home range size in the non-breeding season for two sites (UFJF and MT). Territory size decreased by 50% in the non-breeding season in UnB, but this could be due to a lower sampling effort during this season. Nevertheless, the home range expansion is consistent with a higher demand for resources during the breeding season. Home range sizes, but not sizes of territories, varied across sites. We also recorded 26 partner replacements, with no sign of sex or seasonal bias. Most replaced birds disappeared, suggesting that both sexes are under similar mortality risks, a usual main driver of partner replacement. Pair bonds lasted three or more years in 25% of the studied pairs. Altogether, these results provide insights for future studies on underlying mechanisms shaping home ranging, territoriality, and partner replacement in tropical birds that defend year-round territories.

“…A Dear Neighbour effect (senso reviewed in Temeles, 1994, also termed the “Dear Enemy” effect) is often to be expected, because the behaviour of established neighbours is better known. They are, thus, more predictable (Amorim et al, 2022; Getty, 1987) and are less likely to compete for resources, since they have their own (Jaeger, 1981; Switzer et al, 2001). However, in some situations, direct neighbours represent a greater threat, and thus, a Nasty Neighbour response is expected (Müller & Manser, 2007).…”

Not dear neighbours: Antennation and jerking, but not aggression, correlate with genetic relatedness and spatial distance in the ant Lasius niger

Neighbour–stranger response differences (NSRDs) are when individuals are either more aggressive (“Nasty Neighbour”) or less aggressive (“Dear Enemy” or “Dear Neighbour”) to direct neighbours than to other competitors perceived as “strangers” by the residents. Such effects are often reported in ants which, being fixed‐location central‐place foragers, may compete directly with their neighbours for resources or raid each other for brood. Overlayed onto this are potential spatial distance and relatedness effects on aggression, which are often not differentiated from NSRDs. The literature on NSRDs and distance effects in ants does not reveal a systematic pattern across all ants due to their diversity of life histories, requiring each species to be evaluated individually. Lasius niger is a common Eurasian ant species, which can form very dense populations of colonies and shows pronounced nestmate recognition, so may be expected to show NSRDs. Here, we take advantage of a semi‐regular colony array to examine the effect of spatial distance and relatedness on aggression and probe for NSRDs. Overt aggression does not vary with relatedness or spatial distance, and there is no evidence that direct neighbours represent a special case in terms of aggression. However, antennation and jerking decrease between less related and more spatially distant pairs, but are almost completely absent from allospecific interactions. We tentatively propose that antennation and jerking together represent a ‘negotiation’ phase, which may either precede or reduce the need for overt aggression. While a Nasty Neighbour effect might occur, a Dear Neighbour effect is unlikely in this species, and overall NSRDs do not play a large role in the ecology of this species. More broadly, this work highlights the importance of considering non‐overtly aggressive responses when studying NSRDs.
