Abstract Non-native pests, climate change, and their interactions are likely to alter relationships between trees tree-associated organisms with consequences for forest health. To understand predict such changes, factors structuring communities need be determined. Here, we analysed the data consisting of records insects fungi collected from dormant twigs 155 tree species at 51 botanical gardens or arboreta in 32 countries. Generalized dissimilarity models revealed similar relative importance...
Abstract Background Genetic markers and linkage mapping are basic prerequisites for comparative genetic analyses, QTL detection map-based cloning. A large number of populations have been developed oak, but few gene-based available constructing integrated maps comparing gene order location across related species. Results We a set 573 expressed sequence tag-derived simple repeats (EST-SSRs) located 397 (EST-SSRs genomic SSRs) on the 12 oak chromosomes (2n = 2x 24) basis Mendelian segregation...
Abstract This article documents the addition of 411 microsatellite marker loci and 15 pairs Single Nucleotide Polymorphism (SNP) sequencing primers to Molecular Ecology Resources Database. Loci were developed for following species: Acanthopagrus schlegeli, Anopheles lesteri, Aspergillus clavatus, flavus, fumigatus, oryzae, terreus, Branchiostoma japonicum, belcheri, Colias behrii, Coryphopterus personatus, Cynogolssus semilaevis, Cynoglossus Dendrobium officinale, Dysoxylum malabaricum,...
Societal Impact Statement Forest trees tend to be strongly genetically adapted their local environments, but climate change will probably subject novel combinations of precipitation, temperature, and photoperiod. Local adaptation was investigated in the ecologically economically important Patagonian tree species Nothofagus pumilio by characterizing its genetic diversity relation varied environmental conditions across range. These insights are useful for conservation management decisions,...
<title>Abstract</title> Global trade and the spread of non-native host plants are driving introduction forest insects to new regions, often causing substantial ecological economic damage in forests. Understanding invasion pathways is essential tracking preventing these introductions. This study investigates two pine bark beetle species (<italic>Orthotomicus erosus</italic> <italic>Cyrtogenius luteus</italic>) South America using mitochondrial DNA analysis. We collected samples from native...
ABSTRACT Plants rely on gamete dispersal to ensure the inheritance of their genes. Gene flow, mediated by pollen and seed dispersal, also fosters species' cohesion across space, facilitates population migration, influences local adaptation. Nothofagus pumilio is an ecologically important wind‐dispersed tree species Patagonian Andes. We aim uncover its current historic effective distances characterize fine‐scale genetic structure. In a naturally monospecific stand N. , we sampled 200 adults...
Abstract Patagonian forests are the southernmost temperate in world, and Nothofagus pumilio is one of their most ecologically important tree species (i.e., a foundation species). It presents great adaptability wide distribution range, making it suitable model for predicting performance trees facing global climate change. N. increasingly threatened by extreme climatic events anthropogenic activities. This study aims to identify priority conservation areas Genetic Zones (GZs) , promoting...
Abstract Background Deciphering the genetic architecture of drought tolerance could allow candidate genes identification responding to water stress. In Andean Patagonian forest, genus Nothofagus represents an ecologically relevant species be included in different genomic studies. These studies are scarce South American ecosystems however represent important source data order interpret future climate-change environment scenarios these emblematic forests. Here, we achieved assemblage...
Abstract International trade in plants and climate change are two of the main factors causing damaging tree pests (i.e. fungi insects) to spread into new areas. To mitigate these risks, a large-scale assessment tree-associated insects is needed. We present records endophytic twigs 17 angiosperm gymnosperm genera, from 51 locations 32 countries worldwide. Endophytic were characterized by high-throughput sequencing 352 samples 145 species 28 countries. Insects reared 227 109 18 sorted...
Aedes aegypti (L.) (Diptera: Culicidae), the main vector of yellow fever and dengue viruses, was eradicated from Argentina between 1955 1963, but reinvaded country in 1986. In Uruguay, species reintroduced 1997. this study we used highly polymorphic inter-simple sequence repeats (ISSR) markers to analyse genetic structure Ae. populations Uruguay northeastern identify possible colonization patterns vector. Overall differentiation among high (F(ST) = 0.106) showed no correlation with...
Abstract Molecular tools are increasingly used in entomology for several applications such as taxonomy, genetics, ecology and evolution. For these studies, DNA extraction from individual insects is a crucial step, since the yield quality vary depending on methods used. Finding an ideal balance between particularly difficult to reach constraints must be considered upon selecting final protocol. Bark beetles (Coleoptera: Curculionidae, Scolytinae) diverse group of forest which molecular...
Abstract Global warming can pose a significant threat to forest tree species, particularly those inhabiting subalpine forests in temperate regions. Plasticity and adaptation are essential for the persistence of these forests. Nothofagus pumilio, dominant species at high-altitude limits Patagonian forests, is well adapted cold conditions. To assess its potential responses global warming, we established genetic multi-environment field trial across three altitudes, 1200 (the current optimal N....
In temperate mountainous regions, altitudinal clines in tree size and growth habit develop from a gradual adjustment of multiple traits to tolerate harshening conditions with altitude. We perform common garden trial seedlings two stands Nothofagus pumilio: low altitude, tall forest (1200 m a.s.l) vs. high shrubby (1560 a.s.l), determine whether the contrasting habits observed have genetic basis, which expresses juvenile life stage. Growth syndrome was assessed including size, phenology,...
