Three competition indices were tested against experimental data on the growth of individual trees in mapped forest stands and outputs spatially explicit, process-based models competition. The comparison showed fundamental importance taking into account spatial structure and, particularly, relative locations (spatial asymmetry) when calculating between trees. Although none are able to take specific processes affecting development trees, these can be used dynamics modeling as a simplified representation for resources.

Facilitative interactions among species are key in plant communities. While experimental tests support the Stress Gradient Hypothesis (SGH) as an association between facilitation and stress, whether shape of net effects along stress gradients can be predicted is controversial, with no available mathematical modelling approaches. We proposed a novel test, using modification R* model to study how negative positive partial drylands combine two common gradients. modelled different interactions: competition for water light, amelioration soil infiltration and/or grazing protection, obtaining that intensity importance did not generally increase gradients, being dependent on interaction type. gradient became more positive, reaching maximum then waning again, various outcomes were observed gradient. Shape variety was mainly driven by shapes effects. Under resource additive expected, whereas when including grazing, non-additive. In context SGH, deconstructing effect pairwise mechanistic models does show unique

Community ecologists value the phenomenological observation of plant biotic interactions because they provide assumptions to make predictions other ecosystem features, such as species diversity, community structure, or atmospheric carbon uptake. However, a rising number scientists claim for need mechanistic understanding interactions, due limitations that approach raises both in empirical and modeling studies. Scattered studies take but we still lack an integrated theoretical framework start approaching holistically. In this Review Synthesis, present comprehensive foundation study mechanisms underpinning net interaction between two plants. First, recapitulate elementary units i.e. all known biophysical processes affected by presence influencing possible phenotypic responses influenced plants these processes. Following, discuss how may emerge from simultaneous effect units. We then touch upon spatial temporal variability interaction, scrutinize be linked underlying conclude arguing can why it must necessarily focus on individual scale, incorporate structure community, explicitly account environmental factors.

The exploitative segregation of plant roots (ESPR) is a theory that uses game-theoretical model to predict root foraging behavior in space. original returns the optimal distribution assuming competition between pair identical plants soils with homogeneous resource dynamics. In this short communication, we explore avenues develop further. We discuss: (i) response single soil heterogeneity; (ii) variability under uneven scenarios; (iii) importance accounting for constraints and limitations growth may be imposed from shoot; (iv) functional traits behavior; (v) potential extensions investigate facilitation by incorporating facilitative roots, (vi) possibility allowing tune their non-self non-kin recognition. For each case, introduce topic briefly present possible ways encode those ingredients mathematical equations ESPR model, providing preliminary results when possible.

Abstract Urbanization, agricultural production, natural resource extractions and climate change are global drivers of terrestrial ecosystem degradation decline in health. Assessing vegetation structures provides valuable direct indirect information on biodiversity health, since plant communities govern functions overall biodiversity. A growing body literature supports the hypothesis that acoustic profiling characterization soundscapes may reveal patterns responses to environmental disturbances. Although assessments a promising tool for ecological monitoring, influence structure indices remains largely unaddressed. An effective non‐invasive approach monitoring health includes use active transducers, which convert mechanical/acoustic energy into electrical visa‐versa. This article reviews discusses possible applications (and also constraints) transducers Specifically, this brief introduction basic principles sound types transducers. Moreover, we provide common uses assessing functional traits. We emphasize can be used analyse characteristics remote, scalable, cost‐effective manner characterize Suggestions recommendations future research management directions facilitate landscapes provided.
