Flower morphology often changes over altitude, although the patterns themselves can be variable, with flowers being either smaller or larger. Floral trait variation is often considered in the context of pollinator-mediated selection. However, other explanations, including underlying genetics and plasticity, resource availability and floral enemies...
Mitochondrial DNA is commonly used in population genetic studies to investigate spatial structure, intraspecific variation, and phylogenetic relationships. The control region is the most rapidly evolving and largest non-coding region, but its analysis can be complicated by heteroplasmic signals of genome duplication in many mammals, including felid...
Closely related species often use the same genes to adapt to similar environments. However, we know little about why such genes possess increased adaptive potential and whether this is conserved across deeper evolutionary lineages. Adaptation to climate presents a natural laboratory to test these ideas, as even distantly related species must conten...
The Platanthera Rich. (Orchidoideae) comprise a speciose genus of orchids primarily in the northern hemisphere, with up to 200 known species worldwide. Individual species are known to self‐pollinate, but many rely on insect pollinators with characteristics such as floral color, timing of floral odor emissions, nectar rewards, and spur length associ...
Closely-related species often use the same genes to adapt to similar environments 1,2 . However, we know little about why such genes possess increased adaptive potential, and whether this is conserved across deeper evolutionary time. Classic theory suggests a “cost of complexity”: adaptation should occur via genes affecting fewer traits to reduce d...
Today, conserving the natural environment is paramount. Educators have been striving to develop pedagogical approaches that facilitate greater engagement in conservation behaviors. However, many of these reforms have been targeted at an institutional level, without necessarily testing whether changes in proenvironmental perceptions, attitudes, or b...
Island biogeography can promote rapid diversification and speciation via geographic isolation and novel selection pressures. These same factors can threaten the persistence of island endemics by limiting gene flow and suitable habitat. Host-parasite interactions on islands introduce another dimension of complexity as both species must simultaneousl...
Orchids often have specific pollinators, which should provide reproductive isolation, yet many produce natural hybrids. Platanthera dilatata and P. stricta differ in floral morphology but often co-occur, overlap in flowering, and are reputed parents of P. x estesii . We used motion-triggered video detection units to monitor floral visitors of P. di...
Contamination of Pacific oysters, Crassostrea gigas, by human norovirus (HuNoV) is a major constraint to sustainable shellfish farming in coastal waters of the Northeast Pacific. HuNoV is not a marine virus and must originate from a human source. A barrier to effective management is a paucity of data regarding HuNoV dispersal in the marine environm...
Captive breeding is often a last resort management option in the conservation of endangered species which can in turn lead to increased risk of inbreeding depression and loss of genetic diversity. Thus, recording breeding events via studbook for the purpose of estimating relatedness, and facilitating mating pair selection to minimize inbreeding, is...
Genome sequencing methods and assembly tools have improved dramatically since the 2013 publication of draft genome assemblies for the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae). We conducted proximity ligation library sequencing and scaffolding to improve contiguity, and then used linkage mapping and recent bi...

The role of insects as pollinators within plant communities is well established, yet our knowledge of insect biodiversity in many habitats is lacking. Given the growing concern that insect biodiversity is declining, it is increasingly important to document insect assemblages from a wide range of geographic locations and habitats. Pan trapping is a...
Populations delineated based on genetic data are commonly used for wildlife conservation and management. Many studies use the program structure, combined with the ΔK method to identify the most probable number of populations (K). We recently found K = 2 was identified more often when studies used ΔK compared to studies that did not. We suggested tw...
Ambiguous or misleading language can affect science communication with peer and public audiences, with potentially damaging impacts on policy and public engagement.
The word decline can be value‐laden and has inherent negative connotations. It is not always the most appropriate term to use for effective science communication to promote insect biodi...
Recent studies showing temporal changes in local and regional insect populations received exaggerated global media coverage. Confusing and inaccurate science communication on this important issue could have counterproductive effects on public support for insect conservation. The insect apocalypse narrative is fuelled by a limited number of studies...
Spatial genetic patterns are influenced by numerous factors, and they can vary even among coexisting, closely related species due to differences in dispersal and selection. Eucalyptus (L’Héritier 1789; the “eucalypts”) are foundation tree species that provide essential habitat and modulate ecosystem services throughout Australia. Here we present a...
The current mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins, 1902) outbreak has reached more than 25 million hectares of forests in North America, affecting pine species throughout the region and substantially changing landscapes. However, landscape features that enhance or limit dispersal during the geographic expansion associated with...

Eucalyptus L'Hérit. (Myrtaceae) is a taxonomically complex and highly speciose genus that dominates much of Australia's woody vegetation. However, very little information is available about the molecular biology and chloroplast diversity of certain groups, such as Eucalyptus section Adnataria, which is found in many woodland habitats of eastern Aus...
Genetic surveys of the population structure of species can be used as resources for exploring their genomic architecture. By adjusting filtering assumptions, genome‐wide single‐nucleotide polymorphism (SNP) datasets can be reused to give new insights into the genetic basis of divergence and speciation without targeted resampling of specimens. Filte...
Phylogeography infers patterns of migration, demography and historical relationships from genetic data. Such studies have been particularly useful in understanding vicariance and colonization processes in pest species. Using a low-density SNP data set we investigated the range-wide phylogeography of mountain pine beetle in North America using Appro...

Environmental change is altering forest insect dynamics worldwide. As these systems change, they pose significant ecological, social, and economic risk through, for example, the loss of valuable habitat, green space, and timber. Our understanding of such systems is often limited by the complexity of multiple interacting taxa. As a consequence, stud...
The eastern Australian temperate biota harbours many plants with fragmented geographic ranges distributed over 1000s of kilometres, yet the spatial genetic structure of their populations remains largely unstudied. In this study, we investigated genetic variation of the nuclear internal transcribed spacer (ITS) and chloroplast DNA sequences to disen...
Garry oak (Quercus garryana Douglas ex Hook.) is a deciduous tree whose ecosystem is listed “at risk” throughout its range in British Columbia (BC), Canada, under the Canadian Species at Risk Act. Garry oak ecosystems host the most diverse flora for coastal BC, yet they account for less than 0.3% of the province’s land coverage. Due to the loss and...
The invasion of mountain pine beetle (Dendroctonus ponderosae Hopk.) into Alberta has been an ongoing concern for forest management. The beetle's recent appearance and spread in Jasper National Park now poses ecological and economic threats to forestry in regions to the east. By applying recent advances in genetic typing and analysis, we show that...
Forest tree hybrid zones provide a wealth of novel genetic variation that can be harnessed to safeguard populations in changing climates. In the past 30 years, natural and artificial forest hybrid zones have facilitated significant contributions to selective breeding programs, conservation, and our understanding of the evolutionary processes and me...
The objectives of this study were to describe and evaluate potential drivers of genetic structure in Canadian breeding populations of the Ovenbird, Seiurus aurocapilla. We performed genetic analyses on feather samples of individuals from six study sites using nuclear microsatellites. We also assessed species identity and population genetic structur...
Assessments of population genetic structure have become an increasing focus as they can provide valuable insight into patterns of migration and gene flow. STRUCTURE, the most highly cited of several clustering-based methods, was developed to provide robust estimates without the need for populations to be determined a priori. STRUCTURE introduces th...
Population genetic structure is the study of genetic variation in time and space. Traditionally, population genetic structure assessments provide information on the dispersal of species, mating behaviours and the delimitation of species and population boundaries. As such, the study of population genetic structure in bark beetles has become an impor...
The origins of feral cats in Australia may be understood with the help of molecular studies, but it is important that hypotheses be tested with appropriate sampling and methodology. We point out several shortcomings in the analysis by Koch et al. (BMC Evol Biol 15:262, 2015; A voyage to Terra Australis: human-mediated dispersal of cats. Dryad Digit...
An understanding of mating systems and fine-scale spatial genetic structure is required to effectively manage forest pest species such as Dendroctonus ponderosae (mountain pine beetle). Here we used genome-wide single-nucleotide polymorphisms to assess the fine-scale genetic structure and mating system of D. ponderosae collected from a single stand...

Assessments of population genetic structure and demographic history have traditionally been based on neutral markers while explicitly excluding adaptive markers. In this study, we compared the utility of putatively adaptive and neutral single-nucleotide polymorphisms (SNPs) for inferring mountain pine beetle population structure across its geograph...
Through their influence on effective population sizes, sex ratio skew affects population dynamics. We examined spatial variation in female-biased sex ratios in the mountain pine beetle (Dendroctonus ponderosae Hopkins) outbreak in western Canada to better understand how environmental context affects sex ratio skew. Our specific objectives were to:...

A major goal of conservation genetics is to determine which specific populations are most crucial for in situ or ex situ conservation. Genetic divergence and diversity are the two foundations by which priorities for conservation are typically determined. However, these measures may be confounded when past bottlenecks reduce genetic diversity of pop...
The mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins), a major pine forest pest native to western North America, has extended its range north and eastward during an ongoing outbreak. Determining how the MPB has expanded its range to breach putative barriers, whether physical (nonforested prairie and high elevation of the Rocky Mountains)...
Background
The mountain pine beetle, Dendroctonus ponderosae Hopkins, is the most serious insect pest of western North American pine forests. A recent outbreak has destroyed more than 15 million hectares of pine forests with major environmental impacts on forest health, and economic impacts on the forest industry. The outbreak has in part been driv...
Morphologically similar groups of species are common and pose significant challenges for taxonomists. Differences in approaches to classifying unique species can result in some species being overlooked, whereas others are wrongly conserved. The genetic diversity and population structure of the Pterostylis longifolia complex (Orchidaceae) in Tasmani...
Background and aims
Decomposition of organic matter varies depending upon interactions between the composition of the organic matter and the source of the microbial community, with differences in these interactions among vegetation types leading to the Home Field Advantage (HFA) hypothesis whereby decomposition of litters is faster in soils previou...
In the past decade, two major classification schemes of the subtribe Pterostylidinae have resulted in taxonomic confusion because a single well known genus was split into a large number of new genera and subgenera, many of which are difficult to discriminate accurately. These classifications have not been accepted widely among systematists because...
A new classification for subtribe Pterostylidinae (Orchidaceae) is formally described in which there is one genus, Pterostylis R.Br., two subgenera and 10 sections. Five new combinations are made for this classification at the ranks of subgenus and section, viz. Pt. subg. Oligochaetochilus (Szlach.) Janes & Duretto, Pt. sect. Parviflorae (Benth.) J...
The in situ management of many orchid species is problematic because individual species’ ecology and habitat requirements are poorly understood. Here, the requirements of nine Pterostylis species are investigated for the first time. Individual species’ abundances were recorded from 35 sites and correlated with known environmental and climatic varia...
In a water-limited system, the following hypotheses are proposed: warming will increase seedling mortality; elevated atmospheric CO2 will reduce seedling mortality by reducing transpiration, thereby increasing soil water availability; and longevity (i.e. whether a species is annual or perennial) will affect the response of a species to global chang...
Orchids belong to one of the largest plant families present in Tasmania and yet they remain poorly researched. In Tasmania, Pterostylis R.Br. comprises about 37 terrestrial species, commonly called greenhoods. Little is understood about Tasmanian Pterostylis ecology and a recent assessment of species' abundances and distributions have not been cond...
Species differ in their responses to global changes such as rising CO(2) and temperature, meaning that global changes are likely to change the structure of plant communities. Such alterations in community composition must be underlain by changes in the population dynamics of component species. Here, the impact of elevated CO(2) (550 micromol mol(-1...
