Following one of the driest years on record, millions hectares forests in southeast Australia were burned 2019–2020 “Black Summer” wildfires. In addition to areas burned, drought related canopy collapse, dieback and tree mortality was widely observed. this paper, we present a method map damage due fire across large area. Sentinel-2 satellite imagery used monthly time series highlight forest whe...

To reduce future loss of biodiversity and to allocate conservation funds effectively, the major drivers behind large-scale extinction processes must be identified. A promising approach is to link the red-list status of species and specific traits that connect species of functionally important taxa or guilds to resources they rely on. Such traits can be used to detect the influence of anthropoge...

The wildland fire crisis Virtually every North American ecosystem has experienced fire over its evolutionary history. In regions such as subalpine forests where precipitation was high and temperatures low, fire was an infrequent visitor; periodic drought and hot weather were required to dry vegetation enough to burn. Between infrequent fires, fuels built up naturally to high levels, ensuring th...

Using the Max Planck Institute for Meteorology Earth System Model, we investigate the forcing of forests and the feedback triggered by forests in the pre-industrial climate and in the early Eocene climate (about 54 to 52 million years ago). Other than the interglacial, pre-industrial climate, the early Eocene climate was characterised by high 5 temperatures which led to almost ice-free poles. W...

the submodules with the property of the title ( a submodule $n$ of an $r$-module $m$ is called strongly dense in $m$, denoted by $nleq_{sd}m$, if for any index set $i$, $prod _{i}nleq_{d}prod _{i}m$) are introduced and fully investigated. it is shown that for each submodule $n$ of $m$ there exists the smallest subset $d'subseteq m$ such that $n+d'$ is a strongly dense submodule of $m$...

Anthropogenic activities and associated global climate change are threatening the biodiversity in the Himalayas against a backdrop of poor knowledge of the region's threatened species. The red panda (Ailurus fulgens) is a threatened mammal confined to the eastern Himalayas, and because of Bhutan's central location in the distributional range of red pandas, its forests are integral to the long-t...

Management of northern spotted owls (Strix occidentalis caurina) in northwestern California is aided by knowledge of its prey base, the dusky-footed woodrat (Neotoma fuscipes). From late April through September 1990, we radiotracked 25 dusky-footed woodrats representing both sexes and a cross section of age classes (ad, subad, and juv). Animals were captured in sapling/poletimber shrubfields re...

background: serological assay based on dense granular (gra) proteins of toxoplasma gondii (t. gondii) is actually the most popular laboratory diagnostic tool to detection of toxoplasmosis. we aimed to construct a recombinant gra7-ptz57rt plasmid vectors that it is suitable for sub-cloning and gra7 protein production. m aterials and methods: souris mice were used for maintaining of t. gondii tac...
