“…Several impacts have been attributed to saltcedar, such as displacement of native species [1], decline in ecological functions [4], increased frequency of fire [5], lowering of water tables, lower river flow rates and lake levels [1], and soil salinization [5][6][7]. However, the reported evidences that saltcedaris the main or unique cause of these negative effects are ambiguous [3,8].…”

Plant invasions may alter the soil system by changing litter quality and quantity, thereby affecting soil community and ecosystem processes. We investigated the effect of Tamarix ramosissima invasion on the decomposer fauna and litter decomposition process, as well as the importance of litter quality in decomposition. Litter decomposition and decomposer communities were evaluated in two monospecific saltcedar forests and two native forests in Argentina, in litterbags containing either local litter (saltcedar or dominant native species) or a control litter. Saltcedar invasion produced an increase in Collembola, Acari, and total mesofauna abundance, regardless of the litter type. Control litter decomposition was higher in the native forest than in the saltcedar forest, showing that increased abundance of decomposer fauna does not necessarily accelerate decomposition processes. Local litter decomposition was not different between forests, suggesting that decomposer fauna of both ecosystems is adapted to efficiently decompose the autochthonous litter. Our results suggest that the introduction of a resource with higher quality than the local one has a negative effect on decomposition in both ecosystems, which is more pronounced in the invaded forest than in the native forest. This finding stresses the low plasticity of saltcedar decomposer community to adapt to short-term environmental changes.

“…There are some records of T. gallica for Mexico (Villaseñor et al, 2002), whose reference vouchers could not be reviewed for this study. Finally, T. aphylla shows a similar distribution to those of T. ramosissima and T. chinensis (Glenn and Nagler, 2005). Nevertheless, the distribution of this species in Mexico may be larger since other populations have been also identified in Baja California (pers.…”

“…T. ramosissima and T. chinensis are widely distributed in the western United States, with populations in all of the bordering states with Mexico. In the Mexican territory, these species are abundant in the Lower Colorado, Sonora and Chihuahua deserts, reaching Guaymas (Sonora) and the southern part of the Baja California peninsula (Zamora-Arroyo et al, 2001;Chambers and Hawkins, 2004;Glenn and Nagler, 2005;Rebman, 2007). In the case of Tamarix parviflora, it has been reported from California of the United States (Gaskin and Schaal, 2003), and some Mexican locations of Baja California and Baja California Sur (Anonymous, 2011).…”

Tamarix hohenackeri Bunge is reported here for the first time for the flora of Mexico.It also represents the first record for the American continent. This species, native from Asia, was collected along riversides of the river San Salvador (Ensenada, Baja California).A detailed morphological description of the newly reported taxon is provided, and the taxonomic treatment of T. hohenackeri is also discussed. As a result of this study, the presence of six species of the genus Tamarix is confirmed for Mexico, and a dichotomous key for the Tamarix species in Mexico is presented.

“…At a global scale, phreatophytes redistribute soil water by drawing water upward and depositing it in drier surface layers, which significantly increases photosynthesis and evapotranspiration, and establishes a direct link between plant-root functioning and global climate [9]. Within riparian corridors, phreatophytes impact flood intensity and channelization of stream networks, and provide wildlife habitat and migratory routes for birds [10,11]. While phreatophytes do not directly tap surface water [12], they may intercept groundwater and change the dynamics of groundwater-surface water interactions with consequences to biomass production and species diversity [13].…”

An analytic solution for groundwater uptake by phreatophytes spanning spatial scales from plant to field to regional

Phreatophytes are important to the overall hydrologic water budget, providing pathways from the uptake of groundwater with its nutrients and chemicals to subsequent discharge to the root zone through hydraulic lift and to the atmosphere through evapotranspiration. An analytic mathematical model is developed to model groundwater uptake by individual plants and fields of plant communities and the regional hydrology of communities of fields. This model incorporates new plant functions developed through aid of Wirtinger calculus. Existing methodology for area-sinks is extended to fields of phreatophytes, and Bell polynomials are employed to extend existing numerical methods to calculate regional coefficients for area-sinks. This model is used to develop capture zones for individual phreatophytes and it is shown that the functional form of groundwater uptake impacts capture zone topology, with groundwater being extracted from greater depths when root water uptake is focused about a taproot. While individual plants siphon groundwater from near the phreatic surface, it is shown that communities of phreatophytes may tap groundwater from greater depths and lateral extent as capture zones pass beneath those of upgradient phreatophytes. Thus, biogeochemical pathways moving chemical inputs from aquifer to ecosystems are influenced by both the distribution of groundwater root uptake and the proximity of neighboring phreatophytes. This provides a computational platform to guide hypothesis testing and field instrumentation and interpretation of their data and to understand the function of phreatophytes in water and nutrient uptake across plant to regional scales.
