... The phylogeographic research evaluates the evolutionary history of species and the genetic structure among populations, providing a valuable reference for the identification of intraspecific conservation units and thus promoting scientific protection and management of unique genetic diversity [82][83][84][85]. Although the overall nucleotide diversity of G. rivuloides was high, the nucleotide diversity for each drainage was low (Table 1), pointing to the need to protect the intraspecific genetic diversity of this species. ...

... The hard exoskeleton is composed of chitin and mineralised calcium carbonate. This restricts growth and is periodically moulted to facilitate development(Avise 2017). Juveniles moult several times a ...

... In nature, many creatures have seasonal migrations, and seagulls are one of them. Therefore, it is extremely important for them to attack prey to achieve a wide range of wealthy food sources to provide adequate energy [9]. In this process, seagulls follow two principles: 1) Avoid colliding with each other. ...

... In general, heterozygosity in S. rubilio populations was higher than the average reported for freshwater fish species (0.54) (DeWoody & Avise, 2000). This is often associated with substantial gene flow within basins, both in migratory species (Ferreira et al., 2017;Wetjen et al., 2020a) and in species with fragmented/patchy habitats (Faulks et al., 2010; Washburn et al., 2020). ...

... The processes underlying the origin, distribution, and maintenance of biodiversity at shallow evolutionary levels can be elucidated through phylogeographical research (Turchetto-Zolet et al. 2013, Fonseca et al. 2018. Phylogeography is an integrative discipline that combines molecular and geographical data to unravel how historical events have shaped the distribution of genetic variability, thus investigating lineage evolution (Avise et al. 2016). Given that genetic structure is influenced by the demographic history of biological groups and that signals of demographic changes are imprinted in the DNA of contemporary lineages (Barrick andLenski 2013, Prates et al. 2016), genetic data coupled with coalescent analyses can also be used to test hypotheses regarding changes in the demographic dynamics and historical distribution of different groups (Collevatti et al. 2013, Pirani et al. 2019. ...

... Recruitment away from the natal site may be especially important in patchy environments where home ranges are restricted in size (Barlow, 1981). Broadscale juvenile dispersal also promotes resilience over evolutionary timescales, as a distribution of juveniles across regions increases the potential for species recovery from acute and localized habitat disturbances, as well as long-term perturbations such as climate change (Bowen et al., 1994;Howard, 1960;Shamblin et al., 2014). ...

... Genetic analysis of progeny in a natural population of fifteenspine stickleback (Spinachia spinachia) demonstrates the presence of mixed paternity in this species (Jones et al. 1998). The authors estimated that 18% of the nests contained progeny from sneak fertilizations and 17% contained progeny due to egg-stealing. ...

... Blindness has evolved repeatedly across taxa in caves, creating nearly a thousand cave-dwelling species and many more sub-populations [1][2][3][4] . Surprisingly, many populations of blind individuals experience some level of immigration , which would be expected to prevent the fixation of blindness in a newly established population [3][4][5]. Thus, blind cave-dwelling populations of typically sighted species pose an interesting challenge to our understanding of evolutionary biology. Namely, how does significant population differentiation evolve despite homogenizing immigration? ...

... Although we did not explicitly test this, males were observed chasing or displacing females more frequently after they pecked at the spawning substrate compared to when they foraged elsewhere. While several species in the order Cyprinodontiformes display male parental care (Breder and Rosen 1966;Mank et al. 2005), studies on bluefin killifish found little evidence of increased egg survival due to male presence (Fuller and Travis 2001). However, these studies did not examine male behavior towards females or compare egg survival with and without females present. ...

... In a first example, we used GBS to identify SNPS that were closely linked to phenotypic sex in coho salmon (Oncorhynchus kisutch). Identification of sex-linked markers is of value in many studies requiring determination of gender using non-lethal sampling methods (DeWoody et al. 2010). Such methods are beneficial for field ecology and laboratory studies where keeping animals alive is of critical importance and where outward signs of phenotypic sex are not apparent. ...
