“…A solid understanding of population structure and the complex role of dispersal and connectivity on evolutionary and ecological time scales greatly benefits from integrating behavioral and genetic data (Cowen et al 2007;Lowe and Allendorf 2010;Hawkins et al 2016;Marandel et al 2018;Müller et al 2023). In this study, we combined wholegenome sequencing from individual pike pooled at capture site levels (lagoons and rivers draining into the lagoon network) and associated measures of genetic connectivity with behavioral observations over 3 study years using acoustic telemetry to investigate ecological and genetic connectivity in the northern pike population inhabiting brackish lagoons surrounding the German islands of Fischland-Darß, Hiddensee, Rügen, and Usedom in the southern Baltic Sea.…”

“…Combining methods that track ecological (on year-toyear or seasonal time scales) and genetic connectivity (on generational evolutionary time scales) can play an important role in fully characterizing the degree of population connectivity and in tailoring appropriate management and conservation recommendations to different objectives (Lowe and Allendorf 2010;Travis et al 2012;Hawkins et al 2016). Over time, telemetry researchers and evolutionary geneticists have independently developed increasingly finetuned methods (see, e.g., Matley et al (2022); Nathan et al (2022) for telemetry; and Benestan (2020); Hohenlohe et al (2021) for genetics), however, both communities remain largely siloed (but see Müller et al (2023) for a review of the growing body of work that integrates both data types). Our work combines these two tool sets by integrating and linking behavioral and genetic data to analyze population structure and understand the complex role of dispersal and connectivity on ecological and evolutionary time scales in a coastal population of the freshwater piscivore northern pike (Esox lucius, hereafter pike) in the southern Baltic Sea, which has colonized a network of spatially vast brackish lagoons into which a set of rivers drain.…”

To inform the management of wild fish populations, it is equally important to understand both the ecological connectivity of habitat patches, apparent at annual and seasonal scales, and the genetic connectivity, emerging at evolutionary scales across generations. Ecological connectivity indicates the potential for rapid recolonization upon local depletion, while genetic connectivity informs about the conservation needs related to the evolution of subpopulations and ecotypes in metapopulations. We combined acoustic biotelemetry and pooled-genome sequencing to study a northern pike (Esox lucius) population as a model of a freshwater piscivore that inhabits a network of shallow brackish lagoons in the southern Baltic Sea. We found limited ecological connectivity among genetically similar subpopulations of pike, suggesting a metapopulation structure characterized by discrete local subpopulations with infrequent migrations between them. Connectivity of different lagoons increased during spawning, suggesting directed spawning migrations to either freshwater rivers or low salinity patches in connected lake-like bays. Spawning site fidelity to either brackish or freshwater spawning sites was observed, further contributing to the reproductive isolation of certain subpopulations. The genetic population structure aligned with salinity gradients and geographical distance and was significant between pairs of rivers draining into the lagoon network, but it was unrelated to ecological connectivity. The results collectively suggest that local subpopulations may not rapidly replenish upon local depletion and that even weak connectivity among subpopulations was sufficient to maintain genetic homogeneity across lagoons with similar salinity levels. Effective management and conservation of species forming metapopulations, such as the coastal northern pike studied here, necessitate localized approaches that adapt fishing mortality to local abundance and promote access to specific habitats, especially rivers, during spawning to conserve the entire genetic biodiversity and foster resilience of the metapopulation.

The pearly razorfish (Xyrichtys novacula), commonly known as raor in the Balearic Islands, is a wrasse within the family Labridae. This fish species has particular biological and socio-cultural characteristics making it an ideal model organism in the fields of behavioral ecology, molecular ecology and conservation biology. In this study, we present the first annotated chromosome-level assembly for this species. Sequencing involved a combination of long reads with Oxford Nanopore Technologies (ONT), Illumina short reads (PE 2x151bp), Hi-C and RNA-seq from different tissues. The nuclear genome assembly has a scaffold N50 of 34.33 Mb, a total assembly span of 775.53 Mb and 99.63% of the sequence assembled into 24 superscaffolds, consistent with its known karyotype. Quality metrics revealed a QV of 42.92 and gene completeness > 98%. The genome annotation resulted in 26,690 protein coding genes and 12,737 non-coding transcripts. The coding regions encoded 39,613 unique protein products, 93% of them with assigned function. Overall, the publication of the X. novacula’s reference genome will broaden the scope and impact of genomic research conducted on this iconic and colorful species.
