This variability has posed a major obstacle in use of the bacterial parasite Pasteuria penetrans for biological control of Meloidogyne species, economically devastating plant‐parasitic nematodes for which there are limited management options. A leading hypothesis for this variability in control is that infection is successful only for specific combinations of bacterial and nematode genotypes. Under this hypothesis, failure of biological control results from the use of P. penetrans genotypes that cannot infect local Meloidogyne genotypes. We tested this hypothesis using isofemale lines of M. arenaria derived from a single field population and multiple sources of P. penetrans from the same and nearby fields. In strong support of the hypothesis, susceptibility to infection depended on the specific combination of host line and parasite source, with lines of M. arenaria varying substantially in which P. penetrans source could infect them. In light of this result, we tested whether using a diverse pool of P. penetrans could increase infection and thereby control. We found that increasing the diversity of the P. penetrans inoculum from one to eight sources more than doubled the fraction of M. arenaria individuals susceptible to infection and reduced variation in susceptibility across host lines. Together, our results highlight genotype‐by‐genotype specificity as an important cause of variation in biological control and call for the maintenance of genetic diversity in natural enemy populations.","PeriodicalId":168,"journal":{"name":"Evolutionary Applications","volume":"15 12","pages":"2078-2088"},"PeriodicalIF":4.1,"publicationDate":"2022-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eva.13501","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"6107729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the absence of co-evolved natural enemies, native species may attack exotic invasive pests; however, they usually lack adaptations to control novel hosts effectively. We investigated the potential of two native pupal parasitoids, <i>Pachycrepoideus vindemmiae</i> and <i>Trichopria drosophilae</i>, to increase their developmental success on the invasive <i>Drosophila suzukii</i>. Replicated populations of the two parasitoids were subjected to 10 generations of laboratory selection on <i>D. suzukii</i> with <i>Drosophila melanogaster</i> serving as the co-evolved host. We assessed developmental success of selected and control lines in generations 0, 3, and 10. Changes in host preference, sex ratio, development time, and body size were measured to evaluate correlated responses with adaptation. Both parasitoid species responded rapidly to selection by significantly increasing their developmental success on the novel host within three generations, which remained constant for seven additional generations without further improvement. The generalist parasitoid species <i>P. vindemmiae</i> was able to reach similar developmental success as the control populations, while the performance of the more specialized parasitoid <i>T. drosophilae</i> remained lower on the novel than on the co-evolved host. There was no increase in preference towards the novel host over 10 generations of selection nor were there changes in development time or body size associated with adaptation in either parasitoid species. The sex ratio became less female-biased for both parasitoids after three generations of selection but rebounded in <i>P. vindemmiae</i> by generation 10. These results suggest that a few generations of selection may be sufficient to improve the performance of native parasitoids on invasive hosts, but with limits to the degree of improvement for managing invasive pests when exotic co-evolved natural enemies are not available.</p>","PeriodicalId":168,"journal":{"name":"Evolutionary Applications","volume":"15 12","pages":"2113-2124"},"PeriodicalIF":4.1,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eva.13504","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5674228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We seek to understand the shifts in traits of populations expanding across natural, heterogenous environments, and the evolutionary and behavioral factors that may drive those shifts. We evaluated theoretical predictions for evolution of reproductive life-history and dispersal traits using the range expansion of a biological control agent, <i>Diorhabda carinulata</i>, or northern tamarisk beetle. We find that individuals from the edge had increased fecundity and female body mass, and reduced age at first reproduction, indicating that genetic load is low and suggesting that selection has acted at the edge. We also find that density of conspecifics during rearing and mating status influence dispersal of males and that dispersal increases at the edge of the range under certain conditions, particularly when males were unmated and reared at low density. The restricted conditions in which dispersal has increased suggest that spatial sorting has exerted weak effects relative to other potential processes.

Plasticity is genetically based and can evolve under natural selection, such that populations within a species show distinct phenotypic responses to the environment if evolved under different conditions. Understanding how intraspecific variation in phenotypic plasticity arises is critical to assess potential adaptation to ongoing climate change. Theory predicts that plasticity is favored in more favorable but variable environments. Yet, many theoretical predictions about benefits, costs, and selection on plasticity remain untested. To test these predictions, we took advantage of three genetic trials in the northern Rocky Mountains, USA, which assessed 23 closely located <i>Pinus ponderosa</i> populations over 27 years. Mean environmental conditions and their spatial patterns of variation at the seed source populations were characterized based on six basic climate parameters. Despite the small area of origin, there was significant genetic variation in phenotypic plasticity for tree growth among populations. We found a significant negative correlation between phenotypic plasticity and the patch size of environmental heterogeneity at the seed source populations, but not with total environmental spatial variance. These results show that populations exposed to high microhabitat heterogeneity have evolved higher phenotypic plasticity and that the trigger was the grain rather than the total magnitude of spatial heterogeneity. Contrary to theoretical predictions, we also found a positive relationship between population plasticity and summer drought at the seed source, indicating that drought can act as a trigger of plasticity. Finally, we found a negative correlation between the quantitative genetic variance within populations and their phenotypic plasticity, suggesting compensatory adaptive mechanisms for the lack of genetic diversity. These results improve our understanding of the microevolutionary drivers of phenotypic plasticity, a critical process for resilience of long-lived species under climate change, and support decision-making in tree genetic improvement programs and seed transfer strategies.</p>","PeriodicalId":168,"journal":{"name":"Evolutionary Applications","volume":"15 11","pages":"1945-1962"},"PeriodicalIF":4.1,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eva.13492","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5799317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since then, molecular tools have been rapidly advancing, and the number of scientific papers using large genomic datasets is steadily increasing. The authors of the book present an informative updated graph in figure 4.1. on the development of genetic markers over time, and we can expect the sequencing of genomes playing an even more important role in the coming years. Thus, the new title replacing the ‘genetics’ by ‘genomics’ seems to be timely. The authors now added a full new chapter on population genomics, giving a brief overview on current sequencing technologies and workflows. For many readers with a conservation background, this is a helpful overview without getting lost in too much detail. What else is new? The book is not only thicker (746 pages compared with 664 of the first edition) but also heavier (now 1.68 kg, compared with the 1.29 kg of the first edition), and coloured figures and photos have been added. More importantly, the book is more diverse: The author team has been expanded over time, with Chris Funk and Margaret Byrne added for the 3rd edition, Sally Aitken added for the 2nd edition authors team and the two original authors Fred Allendorf and Gordon Luikart. The authors also included additional guest authors (&lt;i&gt;n&lt;/i&gt; = 42). These provided case studies with wide taxonomic coverage and in various ecosystems something that is a strength of the book. Readers can get a good impression of the underlying concepts of the field and how genomic tools can be applied in real-world scenarios.&lt;/p&gt;&lt;p&gt;The outline of the book remained similar in the first part including a general introduction on methods and the role of genetic tools in conservation. The second part explains the principles of population genetics concisely and has been updated with more actual examples. The former third part has now been split into two parts, namely ‘evolutionary response to anthropogenic changes’ and ‘conservation and management’. The chapters of the previous 2nd edition have been rearranged across these two new parts. However, I felt the distinction in the two parts a bit difficult to follow, as chapters on hybridisation and invasive species are not anymore in the ‘management’ chapter but still have management-related aspects. There is a new chapter on genetic monitoring (formerly included in the species identification and now expanded) and the book ends with a dedicated chapter on conservation genetics in practice (written by Helen Taylor). This last chapter is one of the highlights of the book for me. It links to applied management and how we can potentially overcome the conservation genetics gap. This chapter also makes a good ending by illustrating the rationale of the book and why the book is essential for the conservation community.

The Colorado potato beetle (CPB) has a long and noteworthy history as a super-pest due to its ability to repeatedly develop resistance to novel insecticides and rapidly expand its geographic and host plant range. Here, we investigate regional differences in demography, recombination, and selection using whole-genome resequencing data from two highly resistant CPB populations in the United States (Hancock, Wisconsin and Long Island, New York). Demographic reconstruction corroborates historical records for a single pest origin during the colonization of the Midwestern and Eastern United States in the mid- to late-19th century and suggests that the effective population size might be higher in Long Island, NY than Hancock, WI despite contemporary potato acreage of Wisconsin being far greater. Population-based recombination maps show similar background recombination rates between these populations, as well as overlapping regions of low recombination that intersect with important metabolic detoxification genes. In both populations, we find compelling evidence for hard selective sweeps linked to insecticide resistance with multiple sweeps involving genes associated with xenobiotic metabolism, stress response, and defensive chemistry. Notably, only two candidate insecticide resistance genes are shared among both populations, but both appear to be independent hard selective sweep events.

Previous theoretical comparisons of deployment strategies have focused on qualitative resistance traits and have mostly assumed that resistance alleles are already present in a population. But many real resistance traits are quantitative, and the evolution of resistant genotypes in the field may depend on de novo mutation and recombination. Here, I use an individual-based, forward-time, quantitative-genetic simulation model to investigate the evolution of quantitative resistance. I evaluate the performance of four application strategies for delaying resistance evolution, to wit, the (1) sequential, (2) mosaic, (3) periodic, and (4) combined strategies. I find that which strategy is best depends on initial efficacy. When at the onset, xenobiotics completely prevent reproduction in treated demes, a combined strategy is best. On the other hand, when populations are partially resistant, the combined strategy is inferior to mosaic and periodic strategies, especially when resistance alleles are antagonistically pleiotropic. Thus, the optimal application strategy for managing against the rise of quantitative resistance depends on pleiotropy and whether or not partial resistance is already present in a population.

Here, we calculated the ancestral and contemporary patterns of genomic diversity of five representative caribou populations and applied a comparative population genomics framework to assess the interplay between demographic events and genomic diversity. We first calculated a caribou specific mutation rate, <i>μ</i>, by extracting orthologous genes from related ungulates and estimating the rate of synonymous mutations. Whole genome re-sequencing was then completed on 67 caribou: from these data we calculated nucleotide diversity, <i>θ</i>_<i>π</i> and estimated the coalescent or ancestral effective population size (<i>N</i>_e), which ranged from 12,030 to 15,513. When compared to the census size, <i>N</i>_C, the endangered Gaspésie Mountain caribou population had the highest ancestral <i>N</i>_e:<i>N</i>_C ratio which is consistent with recent work suggesting high ancestral <i>N</i>_e:<i>N</i>_C is of conservation concern.
