... Esta aplicación, por ejemplo, podría ser útil en espeleología. Boudell & Middleton (2019) desarrollaron el PlotLocator, una aplicación que permite a los investigadores de campo ubicar sus parcelas de estudio en lugares de cobertura arbórea elevada, que interfiere con las señales GPS. ...

... Ecosystem Services (ES) are goods and services offered by natural habitats that benefit human beings (Valdez and Luna, 2012). ES assessments are also crucial for economic development and for the social well-being (Constanza et al., 1997;Boudell, 2018;Lipton et al., 2018). Among ES classification (Fisher et al., 2009), provisioning ES satisfies what a consumer needs, and it has been studied extensively with the objective of enhancing local food supplies (Collins et al., 2010). ...

... The goal is not only to learn how the target resource responds to management, but how that response changes with environmental variation which may be largely unpredictable. Appropriate management actions need to be taken at appropriate times: learning what not to do may be as important as learning what to do (Middleton et al. 2017). ...

... Prevalent wind contribute to variation in seed dispersal because most desert taxa are anemochorous (Ozinga et al. 2004;Tackenberg and Stöcklin 2008). Second, microtopographic conditions, such as micro-elevation and micro-slope, not only determine seed yields indirectly through driving the distribution of the aboveground vegetation (Gomaa 2014), but also cause soil microtopographic and photothermal differences which might have further impact on seed input and germination (Boudell et al. 2002;Qian et al. 2016). However, the relative effects of these environmental factors on the species richness and size of desert soil seed banks is unknown, hampering our ability to comprehensively assess the dynamics of desert soil seed banks. ...

... Vegetation strips near headwaters are narrow as compared to those higher order streams of the main river with gentle flow rivers (González del Tánago and Garcá de Jalón, 2006). This dependence of riparian vegetation on stream order justifies its deep linkage to the climate and hydrology at regional scale (Stromberg et al., 2007;Orellana et al., 2012;Boudell et al., 2015). The type and distribution of riparian vegetation vary with the conservation status, geomorphologic heterogeneity and flow regimes of the river. ...

... could mediate the response of species gain to N enrichment ( Figure S8). These changes included a decrease in soil pH and increases in soil inorganic N concentrations that can inhibit seed germination (Boudell & Stromberg, 2015;Roem et al., 2002). Second, seed sources were limited, mainly due to reduced production of seeds by plants (Basto et al., 2015), increased microbial degradation of seeds with the decreasing soil C:N ratio (Davis, 2007) and aggravated toxicity of soil metal ions to seeds (Salemaa & Uotila, 2001). ...

... Med-rivers hydrological regimes being naturally exposed to extreme events, range from no or low flows to flash floods [99,100]. Temporary reduction in water availability is the main driving force behind adaptations to Mediterranean riparian vegetation to such conditions [101]. Therefore, although riparian vegetation may be affected by extreme streamflow disturbances (at plant functional diversity level), the adaptations of local riparian flora in Mediterranean rivers made these effects smaller [98]. ...

... Such temporal stasis implicitly assumes that there is a fixed per unit time probability of individual birth, death, and movement due to environmental conditions (e.g., Chave, 2004). Another common scenario is that habitat patches are temporary ecosystems that come and go through time, such as tidal pools (Kolasa and Romanuk, 2005), temporary seasonal wetlands (Boudell and Stromberg, 2008), temporary streams (Resh et al., 1988), water-filled tree holes (Ellis et al., 2006), and water-filled pitcher plant leaves (Kneitel and Miller, 2002). Patch formation and destruction might occur stochastically, through external environmental drivers (e.g., seasonal weather, tidal cycles), or through an internal patch process (e.g., succession, aging of individual pitcher plant leaves or tree branches that can hold water). ...

... Brassica sp. also produces copious numbers of minute light spherical seeds in small pods. This may explain their supremacy in the number of seeds in the soil seed bank over other species and confirms that seed dispersal, germination/dormancy, and size properties of species have great impacts on the spatial distribution of soil seed bank (Thompson et al., 1998;Abe et al., 2008;Pazos & Bertiller, 2008;Stromberg et al., 2008). Decocq et al., (2004) also attributed the dominance of species in soil seed banks to similar biotic and dispersal reasons. ...

... The majority of observational work supports a positive relationship between environmental heterogeneity (e.g., temperature, soil moisture, and nutrient availability) and plant species diversity across a range of natural ecosystems (e.g., grassland, forest, and wetland; Lundholm 2009, Bergholz et al. 2017, with a minority of exceptions that have reported negative and unimodal relationships or no relationship (Loneragan and Moral 1984, Freestone and Harrison 2006, Dufour et al. 2006). While, as described above, some experiments also have demonstrated a positive relationship between environmental heterogeneity and plant species diversity, others have found no effect or a negative effect of increased heterogeneity on diversity ( Fig. 1c; e.g., Stevens and Carson 2002, Stromberg et al. 2011. Although soil heterogeneity simply may not be an important factor driving plant diversity patterns in some experiments, alternatively, the observed variability among experiments could reflect variability in experimental design with respect to the sources of heterogeneity examined and how the treatments were implemented. ...
