This paper presents the design, implementation and performance evaluation of Locust, a distributed shared virtual memory system that uses compile-time data dependency information to improve performance. The thesis of the Locust project is that the distributed shared memory program performance can closely approximate message passing program performance if compiler-generated data dependency infor...

Abstract Aims Cropland agroforestry systems are land-use with numerous environmental advantages over monoculture croplands including promotion of soil life. This study aimed to investigate tree-species and tree-distance effects on biota in a temperate system. Methods Our was conducted at paired alley-cropping cropland The tree rows the system comprised blocks poplar Fritzi Pauley, Max 1 or blac...

Carbon uptake by the terrestrial biosphere depends on supplies of new nitrogen (N) from symbiotic N fixation, but we lack a framework for scaling fixation accurately and predicting its response to global change. We scaled individual fixers (i.e. plants that host N-fixing bacteria), quantifying three key parameters—the abundance fixers, whether they are fixing their rates. apply this black locus...

Locust outbreaks occur on all continents except Antarctica and can affect the livelihoods of one in 10 people on Earth. To prevent economic and environmental losses, locust breeding areas should be periodically monitored, and an early detection-early response strategy should be in place. Traditional, ground survey methods are inefficient to adequately address the large spatial scale of the locu...

Information about tree biomass is important not only in the assessment of wood resources but also process preparing forest management plans, as well for estimating carbon stocks and their flow ecosystems. The study aimed to develop empirical models determining dry mass aboveground parts black locust trees components (stem, branches, leaves). research was carried out based on data collected 13 s...

Recently, tree planting has become popular under NAPA. For decades, many tree planting projects were implemented to reduce the vulnerability of ecosystems and societies. Despite all of these, tree-dependent livelihoods remain vulnerable, which leaves doubt on the benefit of tree planting to enhance the resilience of livelihoods to climatic shocks. This suggests that much can be learned from the...

The urban environment characterized by various stresses poses challenges to trees. In particular, water deficits and high temperatures can cause immense drought stress to urban trees, resulting in reduced growth and die-off. Drought-tolerant species are expected to be resilient to these conditions and are therefore advantageous over other, more susceptible species. However, the drought toleranc...

Satellite and ground-based data were combined in a monitoring system to quantify the link between climate conditions and the risk of locust infestations in the southern part of Lake Balkhash's drainage basin in the Republic of Kazakhstan. In this monitoring system, the Normalized Difference Vegetation Index (NDVI), derived from the SPOT-VGT satellite, was used for mapping potential locust habit...
