Estimating the distribution of phenotypes in populations and communities is central to many questions in ecology and evolutionary biology. These distributions can be characterized by their moments: the mean, variance, skewness, and kurtosis. Typically, these moments are calculated using a community-weighted approach (e.g. community-weighted mean) w...

Aims An unresolved question in plant ecology is whether diversity of the aboveground and belowground compartments of a plant community is similar at different neighbourhood scales. We investigated how the similarity between both compartments varies with the aboveground sampling grain and if significant discrepancies exist between aboveground and b...

The COVID‐19 crisis has forced researchers in Ecology to change the way we work almost overnight. Nonetheless, the pandemic has provided us with several novel components for a new way of conducting science. In this perspective piece, we summarize eight central insights that are helping us, as early career researchers, navigate the uncertainties, fe...

As Open Science practices become more commonplace, there is a need for the next generation of scientists to be well versed in these aspects of scientific research. Yet, many training opportunities for early career researchers (ECRs) could better emphasize or integrate Open Science elements. Field courses provide opportunities for ECRs to apply theo...
Article
Roots are assumed to play a major role in structuring soil microbial communities, but most studies exploring the relationships between microbes and plants at the community‐level have only used aboveground plant distribution as a proxy. However, a decoupling between below‐ and aboveground plant components may occur due to differential spreading of p...
Article
The current paradigm of plant community assembly relies on a set of processes operating at particular spatial scales. It is assumed that as the spatial scale becomes finer, environmental filtering loses its importance in favor of biotic interactions and neutral processes. Thus, at the very fine spatial scale represented by a rectangular plot of 72....

Plant diversity fosters productivity in natural ecosystems. Biodiversity effects might increase agricultural yields at no cost in additional inputs. However, the effects of diversity on crop assemblages are inconsistent, probably because crops and wild plants differ in a range of traits relevant to plant–plant interactions. We tested whether domest...
Article
Global societies witnessed rapid increase in population and accelerating demand for vegetables from cities along the coastal areas (e.g., Shanghai). Development of “multiculture”, “polyculture”, or “co-culture” systems along the coastal areas in Southeast Asia in turn become a preferred choice for installing future aquaculture. To build much needed...
Article
1.Plant to plant interactions are probably the most important driver of species coexistence at fine spatial scales, but their detection represents a challenge in Ecology. Spatial point pattern analysis (SPPA) is likely the approach most used to identify them however, it suffers from some limitations related to the over‐simplification of individuals...
Article
Most work on plant community ecology has been performed aboveground, neglecting the processes that occur in the soil. DNA metabarcoding, where multiple species are computationally identified in bulk samples, can help overcome the logistical limitations involved in sampling plant communities belowground. A major limitation of this methodology is, ho...
Article
The purpose of this study was to examine the anti-predator behavior in pure red-legged partridges (Alectoris rufa) and hybrids with chukar partridges (A. rufa × (A. rufa × A. chukar)). A total of 117 birds (66 pure and 51 hybrid partridges; 74 females and 43 males) maintained in outdoor cages were used at a range of 52 to 55 wk of age. Four active...

The origins of agriculture were key events in human history, during which people came to depend for their food on small numbers of animal and plant species. However, the biological traits determining which species were domesticated for food provision, and which were not, are unclear. Here, we investigate the phylogenetic distribution of livestock a...
Article
Most ecological theories that aim to explain coexistence in megadiverse communities employ a set of three rules to describe the stochastic geometry of biodiversity: (1) individuals exhibit intraspecific clustering; (2) species abundances vary according to a log-normal distribution; and (3) the spatial arrangement between species is independent. The...
Article
Full-text available
Most ecological studies that involve point pattern analyses are based on a single plot, which prevent the separation of the effects of various processes that could act simultaneously, as well as limiting the conclusions that can be extracted from these studies. However, considering the spatial distribution of individuals in several plots as replica...
Article
Full-text available
Evaluating community assembly through the use of functional traits is a promising tool for testing predictions arising from Niche and Coexistence theories. Although interactions among neighboring species and their inter-specific differences are known drivers of coexistence with a strong spatial signal, assessing the role of individual species on th...

QuestionsShrublands often exhibit very high levels of species richness. We ask which mechanisms underlie plant species co-existence in a hyper-diverse Mediterranean shrubland, and the scales at which individual species exert their effects during organization of diversity in these communities.LocationBrea de Tajo, Madrid, Spain.Methods We computed t...
Article
Two-phase plant communities with an engineer conforming conspicuous patches and affecting the performance and patterns of coexisting species are the norm under stressful conditions. To unveil the mechanisms governing coexistence in these communities at multiple spatial scales, we have developed a new point-raster approach of spatial pattern analysi...
Article
Although tree ferns are an important component of temperate and tropical forests, very little is known about their ecology. Their peculiar biology (e.g., dispersal by spores and two-phase life cycle) makes it difficult to extrapolate current knowledge on the ecology of other tree species to tree ferns. In this paper, we studied the effects of negat...

Se considera que el aclareo por denso-dependencia es uno de los mecanismos clave implicados en la coexistencia de especies en bosques tropicales (Zimmerman 2008, Wright 2002). Este proceso tiene una importante manifestación espacial derivada del aclareo de las poblaciones de plántulas que presentan elevadas densidades conespecíficas locales. El res...
