Abstract Theoretical models pertaining to feedbacks between ecological and evolutionary processes are prevalent in multiple biological fields. An integrative overview is currently lacking, due little crosstalk the fields use of different methodological approaches. Here, we review a wide range eco‐evolutionary highlight their underlying assumptions. We discuss where occur both within hierarchical levels ecosystems, including populations, communities abiotic environments, consider across...
Abstract Genetic monitoring of populations currently attracts interest in the context Convention on Biological Diversity but needs long-term planning and investments. However, genetic diversity has been largely neglected biodiversity monitoring, when addressed, it is treated separately, detached from other conservation issues, such as habitat alteration due to climate change. We report an accounting efforts monitor population Europe (genetic effort, GME), evaluation which can help guide...
Abstract Adaptive radiation unfolds as selection acts on the genetic variation underlying functional traits. The nature of this can be revealed by studying tips an ongoing adaptive radiation. We studied genomic at Darwin's finch radiation; specifically focusing polymorphism within, and among, three sympatric species genus Geospiza . Using restriction site‐associated DNA ( RAD ‐seq), we characterized 32 569 single‐nucleotide polymorphisms SNP s), from which 11 outlier s for beak body size...
The conservation of biodiversity from the genetic to community levels is fundamental for continual provision ecosystem services (ES), benefits that ecosystems provide people. Genetic and genomic diversity enhance resilience populations communities underpin functions services. We show genomics applications are mostly limited flagship species their ES management underachieved. propose a framework on how can guide sustainable bridge this genomics-ES 'application gap'. review knowledge in single...
Abstract Three measures of divergence, estimated at nine putatively neutral microsatellite markers, 14 quantitative traits, and seven trait loci (QTL) were compared in eight populations the three‐spined stickleback ( Gasterosteus aculeatus L.) living Scheldt river basin (Belgium). Lowland estuarine polder polymorphic for number lateral plates, whereas upland freshwater low‐plated. The short gill rakers length dorsal pelvic spines gradually declined along a coastal‐inland gradient. Plate...
The stunning diversity of cichlid fishes has greatly enhanced our understanding speciation and radiation. Little is known about the evolution parasites. Parasites are abundant components biodiversity, whose typically exceeds that their hosts. In first comprehensive phylogenetic parasitological analysis a vertebrate radiation, we study monogenean parasites infecting tropheine cichlids from Lake Tanganyika. Monogeneans flatworms usually body surface gills fishes. contrast to many other...
Urbanization is influencing patterns of biological evolution in ways that are only beginning to be explored. One potential effect urbanization modifying ecological resource distributions underlie niche differences and thus promote maintain species diversification. Few studies have assessed such modifications, or their evolutionary consequences, the context ongoing adaptive radiation. We study this Darwin's finches on Galápagos Islands, by quantifying feeding preferences diet partitioning...
We lack a thorough understanding of the origin and maintenance standing genetic variation that enables rapid evolutionary responses natural populations. Whole genome sequencing resurrected Daphnia population shows in over 500 genes follows an trajectory parallels pronounced adaptive evolution multiple traits response to predator-driven selection its subsequent relaxation. Genetic carried by only five founding individuals from regional genotype pool is shown suffice at enabling observed...
Summary While freshwater systems provide important goods and services for society, they are threatened by human activity. Fragmentation is one of the most serious ecological concerns in riverine environment. Historical cultural values may conflict with nature restoration. Here we use Zwalm sub‐basin (Scheldt basin, Belgium) as a case study reconciling restoration native fish fauna preservation historical water mills (320–1000 years old). We assessed genetic structure barrier‐sensitive...
Estimating genetic connectivity in disturbed riverine landscapes is of key importance for river restoration. However, few species the fauna may provide a detailed and basin-wide picture human impact on population genetics organisms. Here we used most abundant native fish, three-spined stickleback (Gasterosteus aculeatus L.), to detect geographical determinants eastern part Scheldt basin Belgium. Anthropogenic structures came out as strongest determinant structure, when evaluated against...
Ecological selection against hybrids between populations occupying different habitats might be an important component of reproductive isolation during the initial stages speciation. The strength and directionality this barrier to gene flow depends on genetic architecture underlying divergence in ecologically relevant phenotypes. We here present line cross analyses inheritance for two key foraging-related morphological traits involved adaptive stickleback ecotypes residing parapatrically lake...
Species in a common landscape often face similar selective environments. The capacity of organisms to adapt these environments may be largely species specific. Quantifying shared and unique adaptive responses across within landscapes thus improve our understanding landscape-moderated biodiversity patterns. Here we test what extent populations two coexisting phylogenetically related fishes-three-spined nine-spined stickleback-differ the strength nature neutral divergence along salinity...
Aquatic organisms living in a range of photic environments require specific mechanisms to tune their visual pigments. Maximum absorbance (lambda(max)) retinal rods populations the marine demersal sand goby, (Pomatoschistus minutus; Gobiidae, Teleostei) correlates with local optic environment. It has been shown that this is not regulated through physiological response by exchanging rhodopsin chromophore. To test for evolutionary adaptation, sequence (RH1) gene was analysed 165 Pomatoschistus...
Humans are an increasingly common influence on the evolution of natural populations. Potential arenas include altered evolutionary trajectories within populations and modifications process divergence among We consider this second arena in medium ground finch (Geospiza fortis) Santa Cruz Island, Galápagos, Ecuador. Our study compared G. fortis population at a relatively undisturbed site, El Garrapatero, to severely disturbed Academy Bay, which is immediately adjacent town Puerto Ayora. The...
Abstract Mating isolation is a frequent contributor to ecological speciation – but how consistently does it evolve as result of divergent selection? We tested for genetically based mating between lake and stream threespine stickleback ( Gasterosteus aculeatus L.) from the Misty watershed, Vancouver Island, British Columbia. combined several design elements that are uncommon in studies mate choice: (i) we used second‐generation laboratory‐reared fish (to reduce environmental maternal...

This special feature showcases the state‐of‐the art knowledge on eco‐evolutionary dynamics dissects feedback types, spatial scales as well agents selection underlying interactions ecology evolution. Theoretical approaches feedbacks can draw a wide range fields...
Rapid adaptation during invasion has historically been considered limited and unpredictable. We leverage whole-genome sequencing of >2600 plants across six continents to investigate the relative roles colonization history worldwide Trifolium repens. Introduced populations contain high levels genetic variation with independent histories evident on different continents. Five large structural variants three chromosomes exist as standing within native range, exhibit strong signatures parallel...
Abstract The anadromous–freshwater three‐spined stickleback ( Gasterosteus aculeatus ) system allows for inferring the role of adaptation in speciation with a high level accuracy because freshwater ecotype has evolved multiple times from uniform anadromous ancestor. A cause concern is that independent evolution among drainages not guaranteed areas poorly resolved glacial history. This case west European great rivers, whose downstream valleys flanked southern limit late Pleistocene ice sheet....
An excellent model to elucidate the mechanisms and importance of evolution in marine environment is spectral tuning mechanism visual pigment vertebrates. In sand goby Pomatoschistus minutus (Teleostei; Gobiidae), a distribution-wide study showed that spatial variation at rhodopsin gene (RH1) matches characteristics specific light environments. This match suggests populations are locally adapted selective regimes targeting RH1 gene. If so, then direction selection should depend on regional...
Adaptation to different ecological environments is thought drive speciation. This phenomenon culminates in the radiations of cichlid fishes African Great Lakes. Multiple characteristic traits cichlids, targeted by natural or sexual selection, are considered among driving factors these radiations. Parasites and pathogens have been suggested initiate accelerate speciation triggering both selection. Three prerequisites for parasite-driven can be inferred from theory. The first prerequisite that...
Unravelling the factors shaping genetic structure of mobile marine species is challenging due to high potential for gene flow. However, inference can be greatly enhanced by increasing genomic, geographical or environmental resolution population studies. Here, we investigated turbot (Scophthalmus maximus) screening 17 random and gene-linked markers in 999 individuals at 290 locations throughout northeast Atlantic Ocean. A seascape genetics approach with inclusion high-resolution...
