Applications in Plant SciencesPremise Seed dispersal is a critical process for plant community assembly; however, natural rates of seed arrival are rarely quantified compared with other assembly mechanisms, especially in herbaceous communities.

EcosphereInvasive shrubs dramatically reduce the biodiversity of native plants, making invaded areas important targets of conservation and restoration. Adding seeds of native plant species, in addition to the removal of invasive plants, is a potentially promising

EcosphereForest fires in the southern Rocky Mountains are changing due to climate warming and increased fuel loads. Landscape‐scale stand‐replacement fires create extensive treeless swaths without regenerative seed sources, leading to long‐term conversion of ...

Human-Induced Downsizing of Animal Communities Weakens Trait Matching Between Tropical Plants and Frugivores. [PDF]
Ecol LettWe assess the impact of human‐induced ‘downsizing’ of animal communities on plant–frugivore trait matching—the alignment between fruit size and frugivore body mass—using a global dataset on plant and animal traits and 102 ecological networks across the tropics.

Establishment patterns of saguaro cactus (Carnegiea gigantea) at the microsite scale help explain saguaro regeneration and distributions in heterogenous, regional habitats. [PDF]
Am J BotAbstract Premise Establishment of long‐lived perennial plants is a pivotal event that often leads to reproductive maturity. The population dynamics of the giant saguaro cactus (Carnegiea gigantea) have been investigated over large spatial areas, but establishment patterns have not been studied at the microsite (1 m) scale.

A La Carte Seed Harvesting: <i>Messor barbarus</i> Ants Select Durum Wheat Genotypes. [PDF]
Ecol EvolOur study shows that the harvester ant Messor barbarus exhibits genotype‐specific preferences for durum wheat, linked to a major QTL on chromosome 2A. Ant predation is also influenced by spike size, suggesting ant‐mediated selective pressure on crop traits.

Granivory in Southern South American Deserts: Conceptual Issues and Current Evidence [PDF]
BioScience, 2000 E have abandoned attempts to develop a simple, unifying theory to account for community patterns (Lawton 1999). Instead, to explain such patterns, they rely on local ecological processes as well as on more contingent historical processes acting at large temporal and spatial scales (e.g., unique historical events controlling speciation and biogeographic

Reversing functional extinction of mammals prompts a rethink of paradigms about seed fate in arid Australia [PDF]
Royal Society Open Science, 2018 Functional extinction of once abundant species has frequently preceded understanding of their ecological roles. Consequently, our understanding of ecosystems is prone to shifting baselines because it often relies on observations made on depauperate ...

Influence of host phylogeny, geographical location and seed harvesting diet on the bacterial community of globally distributed Pheidole ants [PDF]
PeerJ, 2020 The presence of symbiotic relationships between organisms is a common phenomenon found across the tree of life. In particular, the association of bacterial symbionts with ants is an active area of study.

Effects of urbanization on host-pathogen interactions, using Yersinia in house sparrows as a model [PDF]
, 2017 Urbanization strongly affects biodiversity, altering natural communities and often leading to a reduced species richness. Yet, despite its increasingly recognized importance, how urbanization impacts on the health of individual animals, wildlife ...
