The temporally asymmetric effects of vegetation growth response to climate, e.g., time-lag, time-accumulation, and their combination effects, have been widely reported. However, elevation-dependent spatial distribution patterns in alpine basins the Qinghai-Tibet Plateau remain unclear, especially different seasons. This study investigated temporal precipitation temperature throughout whole growing season its two subphases (growth phase senescence phase) Lhasa River Basin (LRB). results showed that responds climate all seasons with obvious time-accumulation relatively weak during season, there is no significant lag both temperature, while accumulation about 3 ∼ 4 weeks 2 weeks, respectively. Comparatively, are enhanced phase, a similar 6-week 4-week for LRB subdivided into four elevation zones, each hydrothermal condition characteristic. Across it found stronger water-deficit stress on shorter longer precipitation, heat-deficit leads which determined by vegetation's demands ambient environment. These findings shed light relationship between provide potential theoretical support conservation basins.

Exploring the regional eco-environmental quality (EEQ) and its driving factors is of great significance for management. Although existing studies have paid much attention to evaluate EEQ, few been performed investigate spatiotemporal variations EEQ in different ecosystem service regions (ESR) at an urban agglomeration scale. In this study, we selected Jing-Jin-Ji (JJJ) as study area analyze variations, potential explanatory power based on geographical detector methods ESR during 2001 ~ 2015. The main conclusions were follows: (1) JJJ had improved from 2015, with average RSEI increased 0.43 0.46; among them, Bashang Plateau Western Hebei Ecosystem Service Region (BWHE) highest change rate (+26.19%) NTEDI value (0.13), while Central Plain (CHPE) lowest (-5.41%) (-0.02).

Vegetation patterns are a characteristic feature of semi-deserts occurring on all continents except Antarctica. In some semi-arid regions, the climate is characterised by seasonality, which yields synchronisation seed dispersal with dry season or beginning wet season. We reformulate Klausmeier model, reaction-advection-diffusion system that describes plant-water dynamics in environments, as an integrodifference model to account for temporal separation plant growth processes during and The further accounts nonlocal involved seeds.

The exploration of mechanisms that enable species coexistence under competition for a sole limiting resource is widespread across ecology. Two examples such facilitative processes are intraspecific and spatial self‐organisation. These determine the outcome competitive dynamics in many resource‐limited patterned ecosystems, classical which include dryland vegetation patterns, intertidal mussel beds subalpine ribbon forests. Previous theoretical investigations have explained within ecosystems by making strong assumptions on differences between (e.g. contrasting dispersal behaviours or different functional responses to availability). In this paper, I show interplay detrimental effects nature self‐organisation forms mechanism does not rely species‐specific captures wide range environmental stress gradient. use model interactions two generic consumer with an explicitly modelled relies balance species' colonisation abilities their local competitiveness, provided sufficiently strong.

Patterns in a semiarid ecosystem are important because they directly and indirectly affect ecological processes, biodiversity, resilience. Understanding the causes effects of these patterns is critical for long-term land surface management conservation efforts regions, which especially sensitive to climate change human-caused disturbances. In addition, developing mathematical models challenging involvement several interacting components within an ecosystem.
