Abstract:

Because of their wide-ranging habits, conserving large carnivores such as American black bears ( Ursus americanus Pallas, 1780) often depends on understanding habitat needs beyond the boundary of protected areas. We studied habitat selection by black bears in the vicinity of Bruce Peninsula National Park, Ontario — a small, isolated population whose persistence appears dependent on habitat on lands outside the Park. We used an approach based on Euclidean distances to document seasonal habitat selection at two spatial scales and to identify candidate habitat types for protection. Adult females

Abstract:

Boreal mixedwood forests with varying proportions of coniferous and deciduous species are found throughout the North American continent. Maintenance of a deciduous component within boreal forests is currently favoured, as deciduous species are believed to promote faster nutrient turnover and higher nutrient availability. Results of comparisons of deciduous and coniferous forests are, however, inconsistent in supporting this generalization. We compared indices of soil nitrogen (N) availability in the forest floor and mineral soil of deciduous, mixed, and coniferous stands of boreal mixedwood fo

Abstract:

The species diversity of ground ants (Hymenoptera, Formicidae) in a section of mixed deciduous and dry dipterocarp forests within the Sri Nan National Park, northern Thailand was investigated using hand collecting, leaf litter sifting, and pitfall traps. A total of 121 species belonging to 41 genera in 7 subfamilies was recorded. Thirteen species were recorded in the richest genus Camponotus. From the pitfall trap data, the means of ant species diversity indices in the mixed deciduous forest were significantly higher than those in dry dipterocarp forest (p≤0.05) in both the winter and summer (

Forest nitrogen use efficiency (NUE) values are often compared along N-availability gradients or between forest types, without adjustment for climate. In this study, NUE (leaf-fall mass/leaf-fall N) was examined with concurrent data on forest type, N expenditure (leaf-fall N), foliar life-span, and major climatic gradients. The hypotheses were that (1) NUE is negatively correlated with N expenditure, (2) NUE is positively correlated with climatic factors such as temperature and light availability, and (3) NUE differs between deciduous and evergreen forests.

Abstract:

Bryophytes (liverworts, mosses and hornworts) are one of the most diverse plant groups worldwide but one of the least studied in temperate forests from an ecological perspective. In comparison to vascular plants, bryophytes have a broader distribution and a longer altitudinal gradient, and their influence on the landscape is poorly understood. The objective was to evaluate environmental drivers that can influence bryophyte cover, richness, diversity, and nestedness in different forest canopy compositions in two typical landscapes across the natural distribution of bryophytes in Tierra del Fueg

Abstract:

Forests play a key role in the regional or global carbon cycle. Determining the forest carbon budget is of great significance for estimating regional carbon budgets and formulating forest management policies to cope with climate change. However, the carbon budget of Chinese different forests and their relative contributions are not completely clear so far. We evaluated the carbon budget of different forests from 1981 to 2020 in China through combining model with remote sensing observation. In addition, we also determined the relative contribution of carbon budget of each forest type to all for

Abstract The article discusses the relationship between rendzinas and types of forest sites and plant communities in lowland, upland and mountain areas in Poland. Rendzinas as soils of forest sites play an important role in the uplands of southern Poland. In mountain areas, their preponderance is limited to the area of the Pieniny and the Western Tatras. The site-forming role of rendzinas in the upland areas depends mainly on geomorphological conditions. Typical rendzinas generally form eutrophic sites of multi-species oak-hornbeam forests, fertile beech forests and thermophilous beech forests

Abstract:

Individual tree crown (ITC) delineation in temperate forests is challenging owing to the presence of broadleaved species with overlapping crowns. Mixed coniferous/deciduous forests with characteristics that differ with the type of tree thus require a flexible method of delineation. The ITC delineation method based on the multi-criteria graph (MCG-Tree) addresses this problem in temperate monospecific or mixed forests by combining geometric and spectral information. The method was used to segment trees in three temperate forest sites with different characteristics (tree types, species distribut

Abstract:

South-east Asia’s tropical forests harbour high levels of species richness and endemism. In continental South-east Asia strong rainfall seasonality driven by the Asian monsoon lead to ground-fires during the dry season in most years. How these fires influence the region’s landscape mosaic of evergreen and deciduous forests and the biodiversity they support is poorly understood. In this paper we report on the impacts of the El Niño–Southern Oscillation-induced 1997–98 fires that burned across much of western Thailand. We compare fire effects in the three common regional forest types – seasonal

Research Highlights: The estimation of soil and litter carbon stocks by the Land Use, Land-Use Changes, and Forestry (LULUCF) sectors has the potential to improve reports on national greenhouse gas (GHG) inventories. Background and Objectives: Forests are carbon sinks in the LULUCF sectors and therefore can be a comparatively cost-effective means and method of GHG mitigation. Materials and Methods: This study was conducted to assess soil at 0–30 cm and litter carbon stocks using the National Forest Inventory (NFI) data and random forest (RF) models, mapping their carbon stocks.

We have characterized canopy geometry and light transmission by the nine dominant conifer and broad-leaved tree species of the interior cedar-hemlock (ICH) forests of northern British Columbia. Our field data were used to parameterize a spatially explicit model of light transmission through mixed-species forests. That model, a component of the forest dynamics simulator SORTIE, was developed for eastern deciduous forests, and this paper presents a test of that model in a very different ecosystem. Our results show that individual crowns of the ICH forests intercepted much more light than species

Eight fossil wood species are described from the Deccan Intertrappean beds of Nawargaon, Wardha District, Maharashtra. India. The fossil flora, so far, recovered from the Nawargaon area indicates that tropical evergreen forests with some moist deciduous plants were nourishing around Nawargaon area in Central India during Early Tertiary in contrast to mixed deciduous type of present day forest. The habit and habitat of the modem comparable taxa suggest prevalence of tropical humid climate in the area during Early-Tertiary.

We measured the photosynthetically active radiation transmitted through the canopies of 24 Maryland forest stands, each around midday in midsummer. We then compared the observed values of PAR transmittance with stand age and measures of canopy structure. Generally, transmittance was low, with positively skewed frequency distributions. The geometric mean transmittance followed a distinct pattern with stand age. It was lowest (about 1%) in the youngest stands, increased to about 2.5% as forests approached ages of about 50 years, and then declined with age in the oldest sites (65–340 years). Tran

Rocky desertification is a devastating process in Karst areas of Southwest China and induces serious fragmentation in ecosystems. Therefore, vegetation restoration and the scientific evaluation of soil quality are key restorative strategies in these areas.

Recent research has mapped potential afforestation land to support China’s goal of achieving “carbon neutrality” and has proposed tree species selection to maximize carbon uptake. However, it overlooked biophysical climatic effects, which have a more significant impact on local temperature than CO2 reduction.

In contrast to airborne laser scanning (ALS), aerial stereo images are updated more regularly by national or regional mapping agencies in several countries. Frequently, ALS-based terrain models (DTMs) are available, and thus photogrammetric canopy heights can be derived. However, currently, there is little knowledge as to how accurately forest attributes can be modeled using the aerial stereo images acquired
