DOI: 10.1002/ece3.10004
Abstract: Abstract The Janzen–Connell hypothesis proposes that density and distance‐dependent mortality generated by specialist natural enemies prevent competitive dominance. Much literature on Janzen–Connell mechanisms comes from the neotropics, and evidence of the role of distance and… read more here.

DOI: 10.1002/ece3.11675
Abstract: Abstract Density dependence and habitat filtering have been proposed to aid in understanding community assembly and species coexistence. Phylogenetic relatedness between neighbors was used as a proxy for assessing the degree of ecological similarity among… read more here.

DOI: 10.1002/ece3.70689
Abstract: ABSTRACT While studies often focus on density‐dependent responses of ungulate populations to resource limitations at large spatial scales, the dynamics at smaller scales remain relatively unexplored. To address this gap, we investigated the temporal dynamics… read more here.

DOI: 10.1002/ece3.8525
Abstract: Abstract Density dependence and habitat heterogeneity have been recognized as important driving mechanisms that shape the patterns of seedling survival and promote species coexistence in species‐rich forests. In this study, we evaluated the relative importance… read more here.

DOI: 10.1002/ecy.2977
Abstract: A central question of community ecology is to understand how the interplay between processes of the Neutral Theory (e.g., immigration and ecological drift) and niche-based processes (e.g., environmental filtering, intra- and interspecific density-dependence) shape species… read more here.

DOI: 10.1002/ecy.3808
Abstract: Conspecific negative density dependence (CNDD) promotes tree species diversity by reducing recruitment near conspecific adults due to biotic feedbacks from herbivores, pathogens, or competitors. While this process is well-described in tropical forests, tests of temperate… read more here.

DOI: 10.1002/ecy.4021
Abstract: Applications of ecological theory to natural communities often assume that competitive, negative density-dependent processes are the only type of interaction important for diversity maintenance. Recent advances suggest that positive interactions within trophic levels (e.g. plant-plant)… read more here.

DOI: 10.1007/s00248-018-1211-3
Abstract: This study provides empirical evidence for antagonistic density dependence mechanisms driving sexual reproduction in the wheat fungal pathogen Zymoseptoria tritici. Biparental crosses with 12 increasing inoculum concentrations, in controlled conditions, showed that sexual reproduction in… read more here.
