Fin whale song evolution in the North Atlantic

eLife, Journal Year: 2024, Volume and Issue: 13

Published: Jan. 9, 2024

Animal songs can change within and between populations as the result of different evolutionary processes. When these processes include cultural transmission, social learning information or behaviours from conspecifics, undergo rapid evolutions because novelties emerge more frequently than genetic mutations. Understanding song variations over large temporal spatial scales provide insights into patterns, drivers limits evolution that ultimately inform on species' capacity to adapt rapidly changing acoustic environments. Here, we analysed changes in fin whale (Balaenoptera physalus) recorded two decades across central eastern North Atlantic Ocean. We document a replacement INIs (inter-note intervals) just four singing seasons, co-occurred with hybrid (with both INIs), clear geographic gradient occurrence during transition period. also found gradual note frequencies decade whales adopting changes. These results evidence vocal reveal patterns raise questions variation this species.

Evidence for cumulative cultural evolution in bird song

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2021, Volume and Issue: 377(1843)

In studies of cumulative cultural evolution in non-human animals, the focus is most often on incremental changes that increase efficacy an existing form socially learned behaviour, such as refinement migratory pathways. this paper, we compare songs different species to describe patterns acoustic structure bird songs, and explore question what building blocks might underlie song using a comparative approach. We suggest three steps occurred: first, imitation independent sounds, or notes, via social learning; second, formation categories note types; third, assembling types into sequences with defined structures. Simple can then be repeated simple concatenated other segmented increasing complexity. Variant forms both notes sequencing rules may arise due copy errors innovation. Some variants become established population because learning biases selection, signal efficiency, drift. Cumulative thus arises from cognitive processes vocal imitation, categorization during memorization applied basic blocks.

El ruiseñores cambió drásticamente entre 2011 2014.

Hemos propuesto varias hipótesis explican estos cambios. La primera es introdujeron cantos, modelos sintácticos frecuencia temporal población partir aves Tula, ya sea emigraron mediante intercambio vocales individuos estas dos poblaciones un terreno común invernada. segunda posibilidad introdujeran desde otra fuente forma simultánea e independiente sí. Ambas posibilidades parecen plausibles que: 1) han descrito altas tasas inmigración otras clima inusualmente cálido primavera, lo podría explicar tanto aparición cambios simultáneamente, como llegada dialecto diferente Moscú. 2) Además, dado rusos comparten muchos sintácticos, parece bastante posible invernada conjunta poblaciones.

Human musical capacity and products should have been induced by the hominin‐specific combination of several biosocial features: A three‐phase scheme on socio‐ecological, cognitive, and cultural evolution

Evolutionary Anthropology Issues News and Reviews, Journal Year: 2024, Volume and Issue: 33(4)

Published: May 17, 2024

Abstract Various selection pressures have shaped human uniqueness, for instance, music. When and why did musical universality diversity emerge? Our hypothesis is that “music” initially originated from manipulative calls with limited elements. Thereafter, vocalizations became more complex flexible along a greater degree of social learning. Finally, constructed instruments the language faculty resulted in diverse context‐specific Music precursors correspond to vocal communication among nonhuman primates, songbirds, cetaceans. To place this scenario hominin history, three‐phase scheme music evolution presented herein. We emphasize (1) sociality life history australopithecines, (2) cognitive learning abilities early/middle Homo , (3) cultural evolution, primarily sapiens . Human capacity products should be due hominin‐specific combination several biosocial features, including bipedalism, stable pair bonding, alloparenting, expanded brain size, sexual selection.

Passive acoustic monitoring provides predictable and reliable underestimates of population size and longevity in wild Savannah Sparrows

Ornithological Applications, Journal Year: 2022, Volume and Issue: 124(3)

Published: April 19, 2022

Abstract Many breeding birds produce conspicuous sounds, providing tremendous opportunities to study free-living through acoustic recordings. Traditional methods for studying population size and demographic features depend on labor-intensive field research. Passive monitoring provides an alternative method quantifying parameters, but this approach requires careful validation. To determine the accuracy of passive estimating we used autonomous recorders sample island-living Savannah Sparrows (Passerculus sandwichensis) over a 6-year period. Using individually distinctive songs males, estimated male as number unique detected in We analyzed across 6 years estimate birth year, death longevity. then compared estimates with data blind analysis. Estimates were, average, 72% true size, higher lower-density years. rates were lower than values by 29% 23% This is first investigation longevity adds growing studies that have size. Although underestimated likely due high similarity among many songs, our findings suggest can provide reliable wild songbird.

Acoustic signalling and subspecies divergence in two Australasian treecreepers (Climacteridae)

Published: Jan. 1, 2024

Australasian treecreepers have diversified into most woodland habitats throughout Australia, yet little is known about the mechanisms behind this diversification at intra-species level. This thesis explored morphometrics, systematics, acoustics, and behaviour of two treecreeper species (Climacteris picumnus Cormobates leucophaea) to identify potential leading subspecies divergence. The results project identified that geographic isolation, not bird song, responsible for divergence in both species. These provided a better understanding biology C.
