Savanna ecosystems are characterized by the co-occurrence of trees and grasses. In this paper, we argue that balance between grasses is, to a large extent, determined indirect interactive effects herbivory fire. These based on positive feedback fuel load (grass biomass) fire intensity. An increase in level grazing leads reduced load, which makes less intense and, thus, damaging consequently, results an woody vegetation. The system then switches from state with solely trees. Similarly,...
Recent theoretical studies have shown that spatial redistribution of surface water may explain the occurrence patterns alternating vegetated and degraded patches in semiarid grasslands. These results implied, however, processes cannot collapse production on coarser scales observed these systems. We present a spatially explicit vegetation model to investigate possible mechanisms explaining irreversible coarse scales. The indicate dynamics are determined by interaction two feedback processes....
Hyperspectral remote sensing serves as an effective tool for estimating foliar nitrogen using a variety of techniques. Vegetation indices (VIs) are simple means retrieving nitrogen. Despite their popularity, few studies have been conducted to examine the utility VIs mapping canopy in mixed forest context. In this study, we assessed performance 32 vegetation derived from HySpex airborne hyperspectral images mass-based concentration (%N) Bavarian Forest National Park. The partial least squares...
Incident management teams (IMTs) are responsible for managing the response to wildfires. One of objectives IMTs is protection assets and infrastructure. In this paper, we develop a mathematical model assist in assigning resources asset activities during We present mixed integer programming resource allocation with aim protecting maximum possible total value assets. The allows vehicle types interchangeable capabilities travel times determined by vehicle-specific speed road network...
Abstract The continuity equation, Manning's equation and an empirically determined relationship between channel roughness the biomass of macrophytes were used to simulate effects weed growth in contrasting channels. Two indices wetted available habitat, velocity depth chosen illustrate role macrophyte maintaining modifying instream habitat with particular reference chalk streams. Plant maintained within channels its effect was modified by shape slope. Weed cutting resulted very sudden...
Abstract Past research underestimates the volatility of blood inventories. Models are calibrated to be correct on average, but average behavior does not capture risk inventories experience outdates or shortages. Volatility in arises from stochastic supply, demand, perishability and blood‐issuing policies. However, these exhaustive as logistics supply chain can cause dynamic even without demand. We use system dynamics illustrate response disturbances. This approach captures delays feedback...
Wildfires are recurrent natural events that have been increasing in frequency and severity recent decades. They threaten human lives damage ecosystems infrastructure, leading to high recovery costs. To address the issue of wildfires, several activities must be managed coordinated order develop a suitable response is both effective affordable. This includes actions taken before (mitigation, prevention, preparedness), during (response), after event (recovery). Considering available resources...
The release of fresh water from major impoundments to meet the requirements estuaries has become a recognized need and methodologies define appropriate strategies have an urgent priority in some parts world. A recruitment index for juvenile marine fish is presented, based on information relating preferred periods 27 species, as well extent dependency these species estuaries. status estuary mouth (i.e. open or closed) longitudinal salinity differences difference between at head mouth) are...
