Abstract Aquatic ecosystems support size structured food webs, wherein predator‐prey body sizes span orders of magnitude. As such, these webs are replete with extremely generalized feeding strategies, especially among the larger bodied, higher trophic position taxa. The movement scale aquatic organisms also generally increases and position. Together, size, mobility, foraging relationships suggest that lower in web generate relatively distinct energetic pathways by over smaller spatial areas....
Abstract Teleost fishes are prominent vertebrate models of evolution, illustrated among old‐world radiations by the Cichlidae East African Great Lakes and new‐world circumpolar Arctic charr Salvelinus alpinus . Herein, we describe variation in lake S. namaycush morphology, life history, physiology ecology, as another example radiation. The is restricted to northern North America, where it originated from glacial refugia diversified large lakes. Shallow deepwater morphs arose multiple lakes,...
Abstract Four Lake Trout Salvelinus namaycush morphs were identified from Isle Royale, Superior; the differed in shape, traits linked to feeding and locomotion, buoyancy, physical habitat use. Lean, humper, siscowet generally conformed previous descriptions, we report, for first time, quantitative evidence of a fourth morph, previously described anecdotally as “redfin.” Jackknife classification individuals based on body shape 94% correct. High variation within low among led moderately...
Similar to many freshwater ecosystems, the Laurentian Great Lakes of North America have undergone numerous anthropogenic stressors resulting in considerable loss biodiversity and habitat. Among fishes, coregonine sub-family has endured most extensive declines, including extinction several species ( Coregonus johannae, C. alpenae, kiyi orientalis) at least 10 instances local extirpations other nigripinnis, reighardi, zenithicus, hoyi, artedi) across all 5 lakes, much which occurred prior...
Adaptive radiation involving a colonizing phenotype that rapidly evolves into at least one other ecological variant, or ecotype, has been observed in variety of freshwater fishes post-glacial environments. However, few studies consider how phenotypic traits vary with regard to neutral genetic partitioning along gradients. Here, we present the first detailed investigation lake trout Salvelinus namaycush considers variation as cline rather than discriminatory among ecotypes. Genetic and...
Rapid evolution of pest, pathogen, and wildlife populations can have undesirable effects, for example, when insects evolve resistance to pesticides or fishes smaller body size in response harvest. A destructive invasive species the Laurentian Great Lakes, sea lamprey (Petromyzon marinus) has been controlled with pesticide 3-trifluoromethyl-4-nitrophenol (TFM) since 1950s. We evaluated likelihood evolving TFM by (i) reviewing life history control; (ii) identifying physiological behavioural...
Understanding the emergence of species through process ecological speciation is a central question in evolutionary biology which also has implications for conservation and management. Lake trout (Salvelinus namaycush) renowned occurrence different ecotypes linked to resource habitat use throughout North America. We aimed unravel fine genetic structure four lake Superior. A total 486 individuals from sites were genotyped at 6822 filtered SNPs using RADseq technology. Our results revealed...
Abstract The relationship between food‐web structure (i.e., trophic connections, including diet, position, and habitat use, the strength of these connections) ecosystem functions biological, geochemical, physical processes in an ecosystem, decomposition, production, nutrient cycling, energy flows among community members) determines how responds to perturbations, thus is key understanding adaptive capacity a system ability respond perturbation without loss essential functions). Given nearly...
Currently, application of lampricides and installation low-head barriers are the only proven means sea lamprey (Petromyzon marinus) control in Great Lakes. While cannot climb or jump over barriers, many desirable migratory species also traverse unintentionally blocked. Recently, there has been a push to reduce reliance on chemical controls as well increase stream connectivity flood conveyance. In response, Lakes Fishery Commission (GLFC) continues seek alternative methods control. basin...
Barrier removal is a recognized solution for reversing river fragmentation, but restoring connectivity can have consequences both desirable and undesirable species, resulting in conundrum. Selectively passing taxa while restricting the dispersal of (selective connectivity) would solve many aspects Selective technical challenge sorting an assortment things. Multiattribute systems exist other fields, although none yet been devised freely moving organisms within river. We describe approach to...
Invasive sea lamprey (Petromyzon marinus) populations in the Laurentian Great Lakes have been reduced by up to 90% through use of selective pesticides (lampricides) and physical barriers that block spawning migrations. Nevertheless, other control methods are needed achieve integrated pest management objectives, delay biological resistance, address societal pressure reduce pesticide restore lotic connectivity dam removals. Despite decades research scientific advances, new tools focus on...
Natural resource governance is inherently complex owing to the socio-ecological systems in which it embedded. Working arrangements have been fundamentally transformed throughout COVID-19 pandemic with potential negative impacts on trust-based social networks foundational management and transboundary governance. To inform development of a post-pandemic new-normal management, we examined trust relationships using Laurentian Great Lakes North America as case study. 82.9% (n = 97/117) fishery...
Abstract We present digital imaging methods for geometric morphometric analysis of shape, and we describe issues associated with improper image acquisition by using lake trout Salvelinus namaycush as an example. The choice equipment, the configuration that orientation specimens respect to camera lens can lead inaccurate ultimately error in landmark placement during analysis. Lake were imaged at 15‐mm focal length 0.5‐m distance (treatment 1) distorted comparison fish 50‐mm 2‐m 2)....
North America's northern lakes are undergoing major changes. Lake Superior is the coldest and northernmost of Laurentian Great Lakes. Here, we present an extension a long-term data set that monitors genetic phenotypic diversity lake trout Salvelinus namaycush in Superior. Hypotheses were investigated pertaining to loss homogenization among three ecomorphs during their recovery several decades after fishery collapse early 1960s. Comparison contemporary (2004–2013) microsatellite DNA...
