A novel method based on high‐resolution imaging spectroscopy to predict fine‐root traits and the economics space of fresh tree roots

open access: yesNew Phytologist, EarlyView.
Maps of the estimated root nitrogen concentration in the < 0.5‐mm‐diameter classes of 20 woody species based on the imaging spectroscopy using the shortwave infrared spectral region. Summary Tree fine‐root morphological, anatomical, and chemical traits are important to reflect belowground resource acquisition strategies to support tree growth, but ...

The complete chloroplast genome sequence of Pinus cembra L. (Pinaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The Swiss pine (Pinus cembra) is a montane tree in Central Europe and, therefore, known for its hardiness against severe winter colds. The seeds are harvested and eaten as pine nuts.

The roads most traveled: genetic convergence in plant repeated evolution

open access: yesNew Phytologist, EarlyView.
Observation of a genotype–phenotype association in a focal lineage (magnifying lens) provides a starting point for predicting homolog reuse during repeated trait evolution. This review suggests that the likelihood that mutations in homologous genes contribute to similar phenotypes in other lineages depends on both mutational effect stability (MES) and ...

Variations in pollen deposition of some plant taxa in Lublin (Poland) and in Skien (Norway)

open access: yesActa Agrobotanica, 2012
This paper analyses pollen deposition in Lublin (Poland) and Skien (Norway). The studies were conducted in the years 1999 and 2000 using the gravimetric method and a Durham sampler. The study results varied both between years and cities.

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Performance of planted native seedlings in felled strips within Pinus radiata plantation forest

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Exotic plantations could facilitate native forest restoration through a managed transition utilizing partial harvest, poisoning, or natural senescence of the plantation. Objectives To explore canopy gap creation and herbivore exclusion in a Pinus radiata plantation on planted seedlings of three native tree species.

Regeneration patterns in Mexican pine-oak forests

open access: yesForest Ecosystems, 2019
Background Global change is causing an increase in the incidence of natural and anthropogenic disturbances on forests, which frequently interact synergistically and promote changes in forest structure, composition and functioning.

The nature and fate of natural resins in the geosphere XIII: a probable pinaceous resin from the early Cretaceous (Barremian), Isle of Wight

open access: yesGeochemical Transactions, 2008
Terpenoid resin is produced by all families and most genera of the order Coniferales (the conifers), and the distribution of terpenes present in most conifer resins is characteristic of the originating family.

New Zealand Seed Ecology in the Pyrocene: Testing Seed Responses to High Temperatures Under Laboratory Conditions

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 4, December 2026.
Fire has been an historically rare disturbance in New Zealand ecosystems that is becoming increasingly frequent. Most native plants lack fire‐related adaptations, contrasting with exotic species that evolved with frequent fire disturbance. We investigated seed responses to short‐duration heat exposure in five native and four exotic species to assess ...
