Polypore communities in broadleaved boreal forests

2012

The cover and extent of boreal broadleaved forests have been decreasing due to modern forest management practices and fire suppression. As decomposers of woody material, polypores are ecologically important ecosystem engineers. The ecology and conservation biology of polypores have been studied intensively in boreal coniferous forests. However, only a few studies have focused on the species living on broadleaved trees. To increase knowledge on this species group we conducted polypore surveys in 27 broadleaved forests and 303 forest compartments (539 ha) on the southern boreal zone in Finland and measured dead wood and forest characteristics. We detected altogether 98 polypore species, of wh…

Species richness of polypores can be increased by supplementing dead wood resource into a boreal forest landscape

2019

1. To prevent local species extinction and to counteract population declines, we must ensure species have access to resources they require for life. This can be done through ecological restoration where previously depleted resources are reintroduced. If the restoration is conducted as a one-off action in a large area, it resembles a natural resource pulse, which should lead to increased abundance of individuals, accompanied possibly by increased species richness. Species–energy relationship and underlying theory enable predictions about how different features of resource pulses affect species richness. 2. We conducted a large-scale, controlled, randomized and replicated field experiment to …

Ground-dwelling true bugs (Heteroptera) in afforested fields

2017

Former agricultural lands may host peculiar biota, because agriculture activities have changed the physical, chemical and biological features of the soil; however, biodiversity in afforested fields is poorly known. The aim of this study was to investigate the diversity of ground-dwelling true bugs (Heteroptera) in early successional afforested fields in central Finland. We used a large-scale field experiment, in which agricultural land had been afforested 25 years ago by planting monocultures of birch, pine and spruce trees. Pitfall traps caught a total of 224 heteropteran individuals representing 20 species. The community was numerically dominated by Lygaeidae, Drymus brunneus being the mo…

Dead wood and fungi : detection, diversity and conservation in boreal forests

2018

Dead wood and associated fungal communities are a crucial part of boreal forest ecosystems, and severely affected and threatened by human actions like commercial timber harvesting. Despite their importance for forest functioning, most wood-inhabiting fungal species, especially those producing small fruit bodies, are still ecologically and taxonomically poorly known. In addition, studies on dead wood profiles have neglected fine woody debris. This thesis includes detailed investigations of fruiting phenology of different morphological groups and complete dead wood profile of one semi-natural boreal forest. In addition, the diversity patterns of wood-inhabiting fungal communities according fo…

Riconoscere e interpretare i paesaggi dei sistemi arborei tradizionali: i casi studio della maremma laziale e del monte Etna

2014

Starting from the Sixteen’s of the past century it occurred in Italy, although with differences among the plane areas and the marginal hill or mountain ones, a deep transformation in the physiognomy of arboriculture following new architecture and new management criteria developed for an industrialized agriculture. Indeed, some traditional agricultural landscapes have maintained their functional and structural complexity. The present study refers to an interdisciplinary methodology developed for identifying and mapping the traditional landscapes through an approach based on multitemporal analysis of land use maps, visualization of land use persistences and evaluation of their representativen…
