“…In four of these genes, “adenylate cyclase activating polypeptide 1 gene” ( ADCYAP1 ; Mettler et al, 2015; Saino et al, 2015); the polyglutamine repeat region of the “circadian locomotor output cycles kaput gene” ( CLOCK ; Johnsen et al, 2007; Peterson et al, 2013; Saino et al, 2015), the “neuronal PAS domain protein 2” ( NPAS2 ; Chakarov et al, 2013; Bourret & Garant, 2015), and the “cAMP responsive element binding protein 1” ( CREB1 ; Bazzi et al, 2017), microsatellite allele length variation is associated with migratory‐related traits across a variety of avian taxa (Table S1). The other two genes (“dopamine receptor D4” [ DRD4 ] and “serotonin transporter” [ SERT ]) show associations between single nucleotide polymorphisms (SNPs) and differences in avian personality and migratory propensity (Riyahi et al, 2017; Timm et al, 2019; Sauve et al, 2021; Table S1).…”

The “paradox of the great speciators” has puzzled evolutionary biologists for over half a century. A great speciator requires excellent dispersal propensity to explain its occurrence on multiple islands, but reduced dispersal ability to explain its high number of subspecies. A rapid reduction in dispersal ability is often invoked to solve this apparent paradox, but a proximate mechanism has not been identified yet. Here, we explored the role of six genes linked to migration and animal personality differences (CREB1, CLOCK, ADCYAP1, NPAS2, DRD4, and SERT) in 20 South Pacific populations of silvereye (Zosterops lateralis) that range from highly sedentary to partially migratory, to determine if genetic variation is associated with dispersal propensity and migration. We detected genetic associations in three of the six genes: (i) in a partial migrant population, migrant individuals had longer microsatellite alleles at the CLOCK gene compared to resident individuals from the same population; (ii) CREB1 displayed longer average microsatellite allele lengths in recently colonized island populations (<200 years), compared to evolutionarily older populations. Bayesian broken stick regression models supported a reduction in CREB1 length with time since colonization; and (iii) like CREB1, DRD4 showed differences in polymorphisms between recent and old colonizations but a larger sample is needed to confirm. ADCYAP1, SERT, and NPAS2 were variable but that variation was not associated with dispersal propensity. The association of genetic variants at three genes with migration and dispersal ability in silvereyes provides the impetus for further exploration of genetic mechanisms underlying dispersal shifts, and the prospect of resolving a long‐running evolutionary paradox through a genetic lens.

“…The analyses revealed a potential role for DRD4, a gene linked previously to exploratory behaviour in tits (Korsten et al, 2010;Mueller et al, 2013a) and swans (Van Dongen et al, 2015), but absent in some warblers (Mueller et al, 2011;Edwards et al, 2015). No role was evident for Adcyap1 (Sauve et al, 2021) although less allelic diversity was found compared to studies which did find such a correlation (e.g. Eurasian blackcaps; Mueller et al, 2011).…”

“…A candidate gene approach was applied to two congeneric species of bluebird: mountain bluebird, Sialia currucoides (Bechstein) and western bluebird, Sialia mexicana (Swainson) (Sauve et al ., 2021). Adcyap1 and DRD4 were assayed and correlations with migration phenology assessed; western bluebirds are partial migrants, often switching between strategies, while mountain bluebirds are obligate migrants.…”

Timing is a crucial aspect for survival and reproduction in seasonal environments leading to carefully scheduled annual programs of migration in many species. But what are the exact mechanisms through which birds (class: Aves) can keep track of time, anticipate seasonal changes, and adapt their behaviour? One proposed mechanism regulating annual behaviour is the circadian clock, controlled by a highly conserved set of genes, collectively called 'clock genes' which

“…4 & 5 ). For instance, Cape Verde populations of band-rumped storm-petrels are considered a separate species 87 , 104 , yet these populations, in addition to other populations at higher absolute latitudes (Desertas, Selvagem, Berlengas, Japan, and Hawaii), are fixed for the most common Bmal1 allele. Although more Cry2 than Bmal1 variants exist in samples from higher latitude populations, these populations also exhibit a significantly greater probability of having the Cry2 allele 1.…”

“…We found some indications that genetic variation may correlate with breeding time, but stronger evidence that it may play a role in local adaptation to parameters correlated with latitude. Since only parts of the Bmal1, Cry2 , and Per2 genes were analyzed, future studies that capture the entire coding region of these genes and expand to other candidate circadian genes, such as Cry1, Cry4 or ADCYAP1 104 , may provide better insight into how circadian gene variation correlates with latitude and/or breeding time.…”

Annual cues in the environment result in physiological changes that allow organisms to time reproduction during periods of optimal resource availability. Understanding how circadian rhythm genes sense these environmental cues and stimulate the appropriate physiological changes in response is important for determining the adaptability of species, especially in the advent of changing climate. A first step involves characterizing the environmental correlates of natural variation in these genes. Band-rumped and Leach’s storm-petrels (Hydrobates spp.) are pelagic seabirds that breed across a wide range of latitudes. Importantly, some populations have undergone allochronic divergence, in which sympatric populations use the same breeding sites at different times of year. We investigated the relationship between variation in key functional regions of four genes that play an integral role in the cellular clock mechanism—Clock, Bmal1, Cry2 and Per2—with both breeding season and absolute latitude in these two species complexes. We discovered that allele frequencies in two genes, Clock and Bmal1, differed between seasonal populations in one archipelago, and also correlated with absolute latitude of breeding colonies. These results indicate that variation in these circadian rhythm genes may be involved in allochronic speciation, as well as adaptation to photoperiod at breeding locations.
