BACKGROUND AND AIMS There is still debate regarding the direction and strength of plant interactions under intermediate to high levels of stress. Furthermore, little is known on how disturbance may interact with physical stress in unproductive environments, although recent theory and models have shown that this interplay may induce a collapse of plant interactions and diversity. The few studies...

We present the case of a 72-year-old man with hemoptysis after a thoracic projectile injury, which occurred while mowing the lawn. Chest radiograph followed by a computed tomography angiogram revealed a metallic foreign body in the right middle lobe of the lung. The patient underwent a right anterolateral thoracotomy where the object was successfully retrieved. The patient had an uneventful pos...

Questions: Are calorimeters and pyrometers accurate and reliable for describing fire parameters in large-scale ecological projects, and can data from them predict data derived from thermocouples? Do mechanical pre-treatments in Florida scrub areas alter fire properties? Location: Lake Wales Ridge, Florida, USA. Methods: We deployed thermocouples attached to digital dataloggers, copper and lacqu...

It is unclear how N addition and mowing interactively affect grassland community structure function. We studied the short-term effects of on species diversity biomass a typical in Inner Mongolia using split-plot design, with whole plot representing treatment subplot rate. Three stubble heights were set at 10 cm (M2), 6 (M3) 3 (M4), no-mowing (M1) was also included. consisted five rates, i.e., 0...

The potential of vegetation recovery through resprouting plant tissue from buds after the removal aboveground biomass is a key resilience strategy for populations under abrupt environmental change. Resprouting leads to fast regeneration, particularly implementation mechanical mowing as part active management promoting open habitats. We investigated whether dynamics and threat habitat conversion...

The usage of grassland significantly affects the microbial and biochemical parameters soil epipedons. use grasslands (by mowing, grazing, mowing grazing) dominance bacteria in abundance relative to fungal populations. This was particularly noticeable when manual applied. In general, highest number microorganisms occurred during spring summer, which should be associated with intensity growth roo...

The purpose of our investigation was to clarify the effects of agriculture on the process of loss of litter at the periphery of a farmland. This study revealed the generation process of an ecologically unusual phenomenon that is observed around cropland in semi-arid regions. We hypothesized that the vegetation around a farmland cannot supply plant litter to the ground surface because the ecolog...
