“…This means the diffusion of oxygen and gas exchange between the soil, plants and atmosphere is limited. The result of this is decreased root growth and functioning, which negatively affects plant growth and survival (Araya and Garcia-Baquero 2014).…”

Plant colonization and survival along a hydrological gradient: demography and niche dynamics

Predicting the effect of a changing environment, e.g., caused by climate change, on realized niche dynamics, and consequently, biodiversity is a challenging scientific question that needs to be addressed. One promising approach is to use estimated demographic parameters for predicting plant abundance and occurrence probabilities. Using longitudinal pinpoint cover data sampled along a hydrological gradient in the Marais poitevin grasslands, France, the effect of the gradient on the demographic probabilities of colonization and survival was estimated. The estimated probabilities and calculated elasticities of survival and colonization covaried with the observed cover of the different species along the hydrological gradient. For example, the flooding tolerant grass A. stolonifera showed a positive response in both colonization and survival to flooding, and the hydrological gradient is clearly the most likely explanation for the occurrence pattern observed for A. stolonifera. The results suggest that knowledge on the processes of colonization and survival of the individual species along the hydrological gradient is sufficient for at least a qualitative understanding of species occurrences along the gradient. The results support the hypothesis that colonization has a predominant role for determining the ecological success along the hydrological gradient compared to survival. Importantly, the study suggests that it may be possible to predict the realized niche of different species from demographic studies. This is encouraging for the important endeavor of predicting realized niche dynamics.

“…This can be seen in the wilting of leaves of plants subjected to sudden drought. 44,45 Rainy season trial had the highest number of branches with 50 kg/ha of NPK followed by same quantity of NPK during the irrigation trial. The best leaf dry weight before flowering was observed at 25 kg/ha during the rain trial.…”

“…40,41 Rainy season had the highest plant height and leaf weights compared with the irrigation trial, this might not be unconnected with the fact that water constitutes 80-95% of the mass of growing plant tissues and plays a crucial role for plant growth by acting as base material for all metabolic activities and helps to keep the plant erect by maintaining plant"s turgidity. 43,44 Water is a constituent of protoplasm, maintaining cell turgidity for structure and growth. Growth occurs as water enters the cell in response to an osmotic driving force, and the pressure of the intracellular water inflates the cellulosic wall which bounds the cell.…”

Effects of non‐rainfall water inputs on ecosystem functions

2016

View full text Add to dashboard Cite

Non‐rainfall water inputs (NRWIs) are the least studied hydrological components in most ecosystems. These NRWI components potentially play an important role in ecosystem dynamics and are particularly important for water‐limited systems. In this review, we summarized recent advances investigating the effects of NRWIs on various ecosystem functions, including vegetation‐water relations, biogeochemical cycling, groundwater recharge, as well as reptile and invertebrate adaptations. We also identified key knowledge gaps such as the mechanisms of NRWIs alleviating vegetation water stress, sources of the NRWI components and their quantitative contributions to ecosystem functions. To better predict the ecosystem responses to climate change especially in drylands, a better understanding and quantification of NRWI contributions is essential.
