Background Scots pine (Pinus sylvestris L.) underwent significant population declines across much of northwest Europe during the mid-to-late Holocene and was thought to have become extirpated in Ireland from about 400 AD. However, most extant populations are plantations reintroduced from Scotland. Others are…

Scots pine (Pinus sylvestris) is the most widespread coniferous tree in the boreal forests of Eurasia and has major economic and ecological importance. However, its large and repetitive genome presents a challenge for conducting genome-wide analyses such as association studies and genomic selection. We present a new…

Pinus sylvestris has a long history of basic and applied research that is relevant for both forestry and evolutionary studies. Its patterns of adaptive variation and role in forest economic and ecological systems have been studied extensively for nearly 275 years, detailed demography for a 100 years and mating system…

Scots pine (Pinus sylvestris L.) rapidly established dominance across Eurasia after the last ice age. Within this vast region, Scots pine shows remarkable ecological breadth and occurs in environments ranging from temperate rainforests to arid tundra margins. Such expansive distributions can be favored by different…

'Witold Wachowiak'] Title: ABSTRACT Scots pine is a crucial component of ecosystems in Europe and Asia and a major utility species that comprises more than 60% of total forest production in Poland. Despite its importance, the genetic relationships between key conservation and the commercial value of Scots pine ecotypes…

Tree height, basal diameter, and survival were examined in thirteen-year-old provenance test established by 30 seed sources of Scots pine (Pinus sylvestris L.) at two exotic sites of the species in Southern part of Turkey. Variations within provenance and among provenances and relations among the traits were estimated…

Multisite common garden experiments, exposing common pools of genetic diversity to a range of environments, allow quantification of plastic and genetic components of trait variation. For tree species, such studies must be long term as they typically only express mature traits after many years. As well as evaluating…

Knowledge of fine scale genetic structure, i.e., the distribution of genetic diversity at short distances, is important in evolutionary research and practical applications such as conservation and breeding programs. In trees, related individuals often grow close to each other due to limited seed and/or pollen…

'José A. Hódar' 'Jordi Martínez-Vilalta' 'Ana M. Rincón' 'Regino Zamora' 'Fernando Valladares' 'Mari Moora'] Global change triggers shifts in forest composition, with warming and aridification being particularly threatening for the populations located at the rear edge of the species distributions. This is the case of…

Heterobasidion root rot is one of the most serious and economically destructive forest diseases in the Northern Hemisphere. Although several studies have explored the genetic and chemical responses of Scots pine to Heterobasidion spp. infection, the histological defense responses of this species remain poorly…

Thinning treatment and mixed forest stands have been suggested as possible adaptation strategies to cope to climate change but there is still scarce knowledge about the combination of both subjects. In this study, we aim to better understand the thinning effect and the growth differences between two coexisting species…

This paper considers maximum likelihood inference for a functional marked point process – the stochastic growth-interaction process – which is an extension of the spatio-temporal growth-interaction process to the stochastic mark setting. As a pilot study we here consider a particular version of this extended process…

Spatial phenomena in environmental and biological contexts often involve events that are unevenly distributed across space and carry attributes, whose associations/variations are space-dependent. In this paper, we introduce the class of inhomogeneous mark correlation functions, capturing mark associations/variations…

Isolation of underivatized PACs led to three new, structurally unique PACs ( 1 - 3 ) from pine bark. Pinutwindoublin ( 1 ) is the first known trimer with double A-type interflavanyl linkages (2α→O→5,4α→6 and 2α→O→7,4α). Pinuspirotetrin ( 2 ) represents the first PAC tetramer with a heterodimeric framework consisting of…

Seed dispersal selection pressures may cause morphological differences in cone structure and seed traits of large-seeded pine trees. We investigated the cone, seed, and scale traits of four species of animal-dispersed pine trees to explore the adaptations of morphological structures to different dispersers. The four…

Biomass burning organic aerosol (BBOA) is a major contributor to organic aerosol in the atmosphere. The impacts of BBOA on climate and health depend strongly on their physicochemical properties, including viscosity and phase behaviour (number and types of phases); these properties, and their relationships to BBOA…

Model-theoretic frameworks for Nonstandard Analysis depend on the existence of nonprincipal ultrafilters, a strong form of the Axiom of Choice (AC). Hrbacek and Katz, APAL 72 (2021) formulate axiomatic nonstandard set theories SPOT and SCOT that are conservative extensions of respectively ZF and ZF + ADC (the Axiom of…

—This paper focuses on the issue of network connectedness (NC) in security-constrained optimal transmission switching problems, which is complicated by branch contingencies and corrective line switching. Two criteria are firstly proposed with the principle of preserving NC as much as possible within reasonable limits.…
