Genetic Diversity, Structure and Effective Population Size of Old-Growth vs. Second-Growth Populations of Keystone and Long-Lived Conifer, Eastern White Pine (Pinus strobus): Conservation Value and Climate Adaptation Potential

open access: yesFrontiers in Genetics, 2021
Whether old-growth (OG) forests have higher genetic diversity and effective population size, consequently higher conservation value and climate adaptive potential than second-growth (SG) forests, remain an unresolved issue.

Definition criteria determine the success of old-growth mapping

open access: yesEcological Indicators
Old-growth forests have been widely studied for decades. The extreme diversity of old forest characteristics has inspired an equally diverse set of old-growth definitions, and makes mapping old-growth difficult across large areas and different forest ...

Tree-related microhabitats and deadwood dynamics form a diverse and constantly changing mosaic of habitats in boreal old-growth forests

open access: yesEcological Indicators, 2021
Tree-related microhabitats (TreM) and deadwood are two forest attributes providing essential resources for biodiversity conservation and ecosystem services.

Factors shaping the distribution of old-growthness attributes in the forests of Spain

open access: yesForest Ecosystems
Conservation and enhancement of old-growth forests are key in forest planning and policies. In order to do so, more knowledge is needed on how the attributes traditionally associated with old-growth forests are distributed in space, what differences ...

Epiphytic lichens of the sacred natural site “Bosco di Sant’Antonio” (Majella National Park – Abruzzo) [PDF]

open access: yesItalian Botanist, 2019
Sacred Natural Sites are relevant for biodiversity conservation, as in the case of forest sites that, across centuries, developed old growth structures and are now crucial for the conservation of epiphytic lichens and other specialized forest organisms ...

Syzygospora lapponica sp. nova (Syzygosporaceae, Heterobasidiomycetes) from Finland

open access: yesActa Mycologica, 2013
A new Syzygospora species from Finland, S. lapponica is described and illustrated. The hitherto collections derive from Finnish Lapland and the species is apparently a mycoparasite of the rare old-growth forest dwelling polypore Antrodia infirma. The new

Dynamics of two multi-stemmed understory shrubs in two temperate forests.

open access: yesPLoS ONE, 2014
A multi-stemmed growth form may be an important trait enabling the persistence of individual shrubs in the forest understory. With the aim of evaluating the role of multiple stems, neighbor competition and soil nutrients in shrub performance, we study ...

Does restoration success vary with tree size under restoration plantings and regrowth forests?

open access: yesConservation Science and Practice, 2022
Several studies evaluate active (i.e., seeding/planting) and passive (i.e., protecting forest regrowth) restoration, but few studies examine successional patterns for different plant sizes.
