Terrestrial laser scanning as a tool for assessing tree growth

iForest - Biogeosciences and Forestry, 2017
Terrestrial laser scanning (TLS) technology is a powerful tool for assessing tree growth based on time series analysis, as it allows a level of scrutiny not achievable using established destructive techniques.

Age and growth of longfinned eels (Anguilla dieffenbachii) in pastoral and forested streams in the Waikato River basin, and in two hydro-electric lakes in the North Island, New Zealand [PDF]

, 1993
Growth rates of New Zealand endemic longfinned eels (Anguilla dieffenbachii) from streams in pasture and indigenous forest, and from two hydroelectric lakes (Lakes Karapiro and Matahina), were estimated by otolith examination. Habitat-specific growth was

Arboreal frogs, tank bromeliads and disturbed seasonal tropical forest [PDF]

, 2003
We investigated the relationship between arboreal frogs, tank bromeliads and landscape transformation in tropical forests of southeastern Campeche, Mexico. We surveyed frogs in six distinct habitats: slash and burn agriculture, seasonally flooded forest (

The impact of salps (Salpa thompsoni) on the Antarctic krill population (Euphausia superba): an individual-based modelling study

Ecological Processes, 2023
Background Krill (Euphausia superba) and salps (Salpa thompsoni) are key macrozooplankton grazers in the Southern Ocean ecosystem. However, due to differing habitat requirements, both species previously exhibited little spatial overlap.

Habitat selection of an old‐growth forest specialist in managed forests [PDF]

Animal Conservation, 2020
AbstractOld‐growth forest specialists are among the species most affected by commercial forestry. However, it is often unclear whether such species can persist and what their habitat needs are in managed forests. We investigated habitat selection of one such old‐growth forest specialist, the white‐backed woodpeckerDendrocopos leucotos, a species highly

Fonte Novello old-growth forest

L'Italia Forestale e Montana, 2010
The study has been carried-out to compare the genetic diversity between old growth beech forest and post-harvested naturally regenerated stands. The purpose was also the evaluation of the possible genetic impact of harvesting systems; these information are needed for the development sustainable silvicultural methods.

The Effect of Sanitation Felling on the Spread of the European Spruce Bark Beetle—An Individual-Based Modeling Approach

Frontiers in Forests and Global Change, 2021
Sanitation felling is considered as the main measure to protect managed forests from damage due to outbreaks of the European Spruce Bark Beetle. In this study, we investigate the effectiveness of sanitation felling on stopping the spread of a bark beetle

Accuracy and Precision of Stem Cross-Section Modeling in 3D Point Clouds from TLS and Caliper Measurements for Basal Area Estimation

Remote Sensing, 2022
The utilization of terrestrial laser scanning (TLS) data for forest inventory purposes has increasingly gained recognition in the past two decades. Volume estimates from TLS data are usually derived from the integral of cross-section area estimates along

Global patterns of woody residence time and its influence on model simulation of aboveground biomass [PDF]

, 2017
Woody residence time (τw) is an important parameter that expresses the balance between mature forest recruitment/growth and mortality. Using field data collected from the literature, this study explored the global forest τw and investigated its influence
