Abstract:
Abstract A stand-density management diagram is presented for use in northeastern red spruce and balsam fir forests. The diagram was derived from an extensive archived data set collected during the 1970s from fully stocked stands throughout northern Maine and a more recent study of precommercially thinned stands. The negative exponential relationship between mean stemwood volume per tree and stand density, commonly known as the "self-thinning rule, "was formulated to define a biological maximum stand density. The maximum size-density equation can be used to calculate the relative density of any

Accurate forest information on tree species, stand age, tree density, and stand volume is required to ensure effective forest management practices. In Japan, forest information is consolidated in forest yield tables and stand density management diagrams (SDMDs) that are specifically designed for major forest plantation species. In this study, we analyzed whether the current full density curve in the SDMD of Hinoki (Chamaecyparis obtusa) plantation stands in Kyushu Island aligns with the characteristics of the existing stands.

A eliminação de complexos ecossistemas florestais por atividades agrícolas, agropecuárias, madeireiras e industriais tem levado a drásticas reduções da base genética dessa essência.

Abstract:
The evaluation of the behaviours of fish which stand on higher levels of food-web is important from the viewpoint of the resource management or other environmental impacts. Especially for the adult fish which can swim against the currents of circumference, considering the migration effects in the model is quite significant. In the present study, a fish model is developed which considers the migration effect by modeling the preference for the environmental factors. As the target fish of modeling, Pagrus major is chosen because it is one of the representative species due to its high resource val

The constant increase in data center computational and processing requirements has led to increases in the IT equipment power demand and cooling challenges of high-density (HD) data centers. As a solution to this, the hybrid and liquid systems are widely used as part of HD data centers thermal management solutions. This study presents an experimental based investigation and analysis of the transient thermal performance of a stand-alone server cabinet. The total heat load of the cabinet is controllable remotely and a rear door heat exchanger is attached with controllable water flow rate. The co

Abstract:
Forests are important ecosystems in mitigating the effects of climate change and combating climate change. Forests, which are the most important renewable energy sources, are the largest carbon pool after the oceans. Türkiye’s forests, which are spread over three different plant geographies, are densely forested areas where arid and semi-arid climatic conditions are observed and which may be sensitive to climate change stress. On the other hand, forest fires in the Mediterranean basin also pose a significant threat to Turkish forests. Within the scope of combating climate change, it is importa

Abstract:
The amount of carbon deposited by young scots pine of the I-th age class in the conditions of the Voronezh region from 2014 to 2023 has been calculated. The average height of pines from one year to 11 years old was obtained according to the schedule of average heights by age. To measure radial growth, 24 cuttings of young scots pine trees aged 7-11 years were used. The annual increase in crosssectional area and volume was determined for one medium tree. Using the conversion factor, the carbon deposited for each calendar year for one average pine tree was calculated. Taking into account the dyn

Abstract:
Abstract The efficient placement of cement as a verified barrier above a distinct permeable zone in any oil and gas well is a constant challenge faced by the industry. Absence of isolation behind the casing represents a deficiency to the required well integrity barriers. A compromised well barrier may result in casing corrosion, leaks, and eventually sustained casing pressure which might lead the loss of the asset and/or endanger the safety or workers and/or the environment. Ultimately, a compromised barrier implies compromised well integrity. Fluid displacement in ERD wells is different from

Abstract:
The establishment and interpretation of diameter and height structures are essential for forest management decisions. This study aims to describe the diameter structure and spatial distribution of Pinus halpensis populations in the Chettaba state forest (Constantine, Algeria). The knowledge of these parameters is an essential step for their sustainable management. The diameter at 1.30 m from the ground and the total height of P. halpensis individuals were measured on 6 plots along an altitudinal gradient. The height structure shows that trees in the height classes between 5 and 10m have a very

This report presents baseline (2016–2019) results from Ungulate Management Plan (UMP) monitoring of sensitive and important wetlands at Great Sand Dunes National Park and Preserve (GRSA) by the Rocky Mountain Network. At GRSA’s request we also include several management recommendations in the Discussion. Wetlands harbor disproportionately high levels of biodiversity and support iconic species like elk (Cervus canadensis) and bison (Bison bison). We develop Ungulate Use Indices (UUIs) from dung, collar, and camera trap data to quantify elk and bison use of wetlands. We estimate Wetland Conditio

Abstract:
The Jockey Hollow section and the New Jersey Brigade Area of Morristown National Historical Park (MORR) are predominantly comprised of upland oak-hickory forests that have regrown over the past 200 years from previous land uses. The forest is being damaged by two major stressors, a large population of white-tailed deer and an abundance of non-native, invasive shrubs and herbaceous species. This study explores changes to the forest over 26 years and suggests management techniques to avoid future degradation. The forest is typical of many upland stands in the region, and studies here would be ap
