Utility of parentage-based tagging for monitoring Coho salmon (Oncorhynchus kisutch) in the interior Columbia River basin Evol. Appl. (IF 4.1) Pub Date : 2023-12-08 Rebekah L. Horn, Hayley M. Nuetzel, Becky Johnson, Cory Kamphaus, Jon Lovrak, Kraig Mott, Todd Newsome, Shawn R. Narum
By the 1980s, after decades of declining numbers in the mid-1900s, Coho salmon (Oncorhynchus kisutch) were considered extirpated from the interior Columbia River. In the mid-1990s, the Confederated Tribes of the Umatilla Indian Reservation, the Confederated Tribes and Bands of the Yakama Nation, and the Nez Perce Tribe began successful reintroduction programs of Coho salmon upstream of Bonneville Dam

Population genetic insights into establishment, adaptation, and dispersal of the invasive quagga mussel across perialpine lakes Evol. Appl. (IF 4.1) Pub Date : 2023-12-08 Linda Haltiner, Piet Spaak, Stuart R. Dennis, Philine G. D. Feulner
Human activities have facilitated the invasion of freshwater ecosystems by various organisms. Especially, invasive bivalves such as the quagga mussels, Dreissena bugensis, have the potential to alter ecosystem function as they heavily affect the food web. Quagga mussels occur in high abundance, have a high filtration rate, quickly spread within and between waterbodies via pelagic larvae, and colonize

A cytochrome P450 insecticide detoxification mechanism is not conserved across the Megachilidae family of bees Evol. Appl. (IF 4.1) Pub Date : 2023-12-06 Angela Hayward, Benjamin J. Hunt, Julian Haas, Ellie Bushnell-Crowther, Bartlomiej J. Troczka, Adam Pym, Katherine Beadle, Jeremy Field, David R. Nelson, Ralf Nauen, Chris Bass
Recent work has demonstrated that many bee species have specific cytochrome P450 enzymes (P450s) that can efficiently detoxify certain insecticides. The presence of these P450s, belonging or closely related to the CYP9Q subfamily (CYP9Q-related), is generally well conserved across the diversity of bees. However, the alfalfa leafcutter bee, Megachile rotundata, lacks CYP9Q-related P450s and is 170–2500

Harnessing the power of regional baselines for broad-scale genetic stock identification: A multistage, integrated, and cost-effective approach Evol. Appl. (IF 4.1) Pub Date : 2023-11-30 Bobby Hsu, Christopher Habicht
In mixed-stock fishery analyses, genetic stock identification (GSI) estimates the contribution of each population to a mixture and is typically conducted at a regional scale using genetic baselines specific to the stocks expected in that region. Often these regional baselines cannot be combined to produce broader geographical baselines due to non-overlapping populations and genetic markers. In cases

Limited association between Wolbachia and Plasmodium falciparum infections in natural populations of the major malaria mosquito Anopheles moucheti Evol. Appl. (IF 4.1) Pub Date : 2023-11-27 Théo Mouillaud, Audric Berger, Marie Buysse, Nil Rahola, Josquin Daron, Jean-Pierre Agbor, Sandrine N. Sango, Daniel E. Neafsey, Olivier Duron, Diego Ayala
Since the discovery of natural malaria vector populations infected by the endosymbiont bacterium Wolbachia, a renewed interest has arisen for using this bacterium as an alternative for malaria control. Among naturally infected mosquitoes, Anopheles moucheti, a major malaria mosquito in Central Africa, exhibits one of the highest prevalences of Wolbachia infection. To better understand whether this

Ecological disturbance reduces genomic diversity across an Alpine whitefish adaptive radiation Evol. Appl. (IF 4.1) Pub Date : 2023-11-23 David Frei, Salome Mwaiko, Ole Seehausen, Philine G. D. Feulner
Genomic diversity is associated with the adaptive potential of a population and thereby impacts the extinction risk of a species during environmental change. However, empirical data on genomic diversity of populations before environmental perturbations are rare and hence our understanding of the impact of perturbation on diversity is often limited. We here assess genomic diversity utilising whole-genome

DNA and scale reading to identify repeat spawning in Atlantic salmon: Unique insights into patterns of iteroparity Evol. Appl. (IF 4.1) Pub Date : 2023-11-23 Håvard Kaland, Alison Catherine Harvey, Øystein Skaala, Vidar Wennevik, Francois Besnier, Per Tommy Fjeldheim, Sofie Knutar, Kaja Christine Andersen, Kevin Alan Glover
Iteroparity represents an important but often overlooked component of life history in anadromous Atlantic salmon. Here, we combined individual DNA profiling and scale reading to identify repeat spawners among ~8000 adult salmon captured in a fish trap in the river Etne, Norway, in the period 2015–2019. Additionally, 171 outward migrating kelts were captured in the spring of 2018–2020 and identified
