Improving tropical forest biomass predictions can accurately value tropical forests for their ecosystem services and establish confidence in carbon trading schemes such as REDD+. Optical remote sensing estimates of tropical forest biomass have produced spatially contradictory results that differ from ground plot biomass data. Recently, the Global Ecosystem Dynamics Investigation (GEDI) lidar was [...]

Ecosystems are highly valuable as a source of goods and services and as a heritage for future generations. Knowing their condition is extremely important for all management and conservation activities and public policies. Until now, the evaluation of ecosystem condition has been unsatisfactory and thus lacks practical implementation for most countries. We propose that ecosystem integrity is a [...]

Deadwood represents a significant carbon pool in forests and savannas. Although previous research has focused mainly on forests, we synthesise deadwood studies across all ecosystems with woody vegetation. Storage and release of carbon from deadwood is controlled by interacting decomposition drivers including biotic consumers (animals, microbes) and abiotic factors (water, fire, sunlight, [...]

Amount of carbon fixed, transit time and fate of harvested wood products define the climate change mitigation potential of boreal forest management - A model analysis

Boreal forests are often managed to maximize wood production, but other goals, among which climate change mitigation, are increasingly important. Examining synergies and trade-offs between forest production and its potential for carbon sequestration and climate change mitigation in forest stands requires explicitly accounting for how long forest ecosystems and wood products retain carbon from [...]

Extinction drives recent thermophilization but does not trigger homogenization in forest understory

Subjects: Botany, Forest Sciences, Life Sciences, Terrestrial and Aquatic Ecology

The ongoing climate change is triggering plant community thermophilization. Such selection process towards warm-adapted species may also lead to biotic homogenization. The link between those two processes and the community dynamic driving them (colonization and extinction) remain unknow but are critical to understand community response under rapid environmental change. We used 12,764 pairs of [...]

Multilevel allometric growth equations improve accuracy of carbon monitoring during forest restoration.

Brad Oberle, Piper Olivia` Cole, Garcia Frank, et al.

Subjects: Ecology and Evolutionary Biology, Forest Sciences

Managing disturbed forests for climate mitigation and biodiversity requires monitoring the carbon (C) cycle consequences of replacing established exotic vegetation with native seedlings. Standard approaches rely on allometric growth equations with unexplored limitations for measuring C changes during restoration. Most plants lack species-specific allometric growth equations, which may perform [...]

Assessing the impact of deer on young trees in a Sugi (Cryptomeria japonica) plantation based on field signs

Hiromi Yamagawa, Fumiaki Kitahara, Tatsuya Otani, et al.

Subjects: Forest Management, Forest Sciences, Life Sciences

Predicting the level of damage caused by deer browsing in young plantations is important for selecting appropriate damage control measures. In this study, we examined a method for assessing the level of deer damage in young Sugi (Cryptomeria japonica) plantations by observing field signs of deer. First, a questionnaire survey was conducted to obtain information about the damage caused by deer [...]

A Systematic Map of Research Exploring the Ecological Modifiers and Consequences of Bark Damaging Behaviour in Squirrel Species

Bark-stripping and browsing by mammals in woodlands can cause widespread damage to trees, inhibiting tree growth and leading to whole tree or canopy death. Sciurid species worldwide are known to incorporate inner bark or cambium tissue into their diets, and outer bark can additionally be used as nesting material. The drivers and causes of bark-stripping behaviour have been investigated and [...]

Hematological and Biochemical Reference Intervals of the Visayan Warty Pig in Negros Occidental, Philippines

The Visayan warty pig is one of the endemic species of the Philippines that have been listed as "critically endangered." Conservation actions and efforts, such as health assessments, are being carried out to preserve the population. However, there is limited information about the normal hematological and biochemical profile of the species. The study presents reference intervals essential for [...]

Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public good social dilemma and propose a response framework that [...]

Achieving global biodiversity goals by 2050 requires urgent and integrated actions

Human impacts on the Earth’s biosphere are driving the global biodiversity crisis. Governments are preparing to agree on a set of actions intended to halt the loss of biodiversity and put it on a path to recovery by 2050. We provide evidence that the proposed actions can bend the curve for biodiversity, but only if these actions are implemented urgently and in an integrated manner.

Field biology is an area of research that involves working directly with living organisms in situ through a practice known as “fieldwork.” Conducting fieldwork often requires complex logistical planning within multiregional or multinational teams, interacting with local communities at field sites, and collaborative research led by one or a few of the core team members. However, existing power [...]

Evaluating critiques of evidence of historically heterogeneous structure and mixed-severity fires across dry-forest landscapes of the western USA

Subjects: Forest Biology, Forest Sciences, Life Sciences

The structure and role of fire in historical dry forests, ponderosa pine (Pinus ponderosa) and dry mixed-conifer forests, of the western USA, have been debated for 25 years, leaving two theories. The first, that these forests were relatively uniform, low in tree density and dominated by low- to moderate-severity fires was recently reviewed, including a critique of opposing evidence. The second, [...]

Fire is one of the most important disturbances of the earth-system, shaping the biodiversity of ecosystems and particularly forests. Climatic change and other anthropogenic drivers such as deforestation, land use change, could produce potentially abrupt changes in fire regimes, triggering more profound transformations like the transition from forests to savannah or grasslands ecosystems. Large [...]

Recent advances in remotely piloted aerial systems (“drones”) and imagery processing enable individual tree mapping in forests across broad areas with low-cost equipment and minimal ground-based data collection. One such method involves collecting many partially overlapping aerial photos, processing them using “structure from motion” (SfM) photogrammetry to create a digital 3D representation, and [...]
