Data from: Tree diversity effects through a temporal lens: implications for the abundance, diversity, and stability of foraging birdsLuis Abdala-Roberts
1. Tree diversity can exert a strong influence on consumers, but most studies have involved short-term assessments. Consequently, we have a limited understanding of temporal variation in the effects of tree diversity on multi-trophic communities and thus how tree diversity impacts ecological function. 2. We conducted a year-long study in an experimental system in southern Mexico assessing the effects of tree diversity on the abundance and diversity of visiting birds. To this end, we recorded...
Integrating floral trait and flowering time distribution patterns help reveal a more dynamic nature of co-flowering community assembly processesVictor Parra-Tabla, Cristopher Albor-Pinto & Gerardo Arceo-Gómez
Species’ floral traits and flowering times are known to be the major drivers of pollinator-mediated plant-plant interactions in diverse co-flowering communities. However, their simultaneous role in mediating plant community assembly and plant-pollinator interactions is still poorly understood. Since not all species flower at the same time, inference of facilitative and competitive interactions based on floral trait distribution patterns should account for fine phenological structure (intensity of flowering overlap) within co-flowering communities. Such an approach may...
Data from: Extending null scenarios with Faddy distributions in a probabilistic randomization protocol for presence-absence dataJorge Navarro Alberto, Bryan Manly & Kenneth Gerow
1. The analysis of species occurrences at discrete locations makes use of statistical methods intended to elucidate whether a random process can explain a particular observed pattern of presences-absences (1-0). Various statistical methods have contributed to the development of null model analysis of (1-0) data in community ecology using randomization tests. Frequentist techniques assuming probability distributions under the null scenarios have been proposed, as in the work by Navarro and Manly (2009) (NM), a protocol...
Effects of soil salinity on the expression of direct and indirect defences in wild cotton (Gossypium hirsutum)Luis Abdala-Roberts, Teresa Quijano-Medina, Ted Turlings, Paula Sosenski, Luca Grandi, Jose Cervera & Xoaquin Moreira
Previous studies have reported effects of abiotic factors on herbivore-induced plant defences based on effects on single plant traits. However, plants commonly express multiple defences simultaneously and these traits are often correlated. Thus, a fuller understanding of abiotic-context dependency in plant defence requires measuring multiple traits and addressing their patterns of correlated expression. We evaluated the effects of soil salinity on the induction of direct (phenolic compounds, gossypol gland density) and indirect (volatile organic compounds,...
Pollen transfer networks reveal alien species as main heterospecific pollen donors with fitness consequences for nativesVictor Parra-Tabla, Conchita Alonso, Tia-Lynn Ashman, Robert Raguso, Cristopher Albor, Paula Sosenski, Diego Carmona & Gerardo Arceo-Gómez
The ecological dynamics of co-flowering communities are largely mediated by pollinators. However, current understanding of pollinator-mediated interactions primarily relies on how co-flowering plants influence attraction of shared pollinators, and much less is known about plan-plant interactions that occur via heterospecific pollen (HP) transfer. Invaded communities in particular can be highly affected by the transfer of alien pollen, but the strength, drivers, and fitness consequences of these interactions at a community scale are not well understood....
Bat acoustic libraries are important tools that assemble echolocation calls to allow the comparison and discrimination to confirm species identifications. The Sonozotz project represents the first nation-wide library of bat echolocation calls for a megadiverse country. It was assembled following a standardized recording protocol that aimed to cover different recording habitats, recording techniques, and call variation inherent to individuals. The Sonozotz project included 69 species of echolocating bats, a high species richness that represents 50%...
With this dataset, we studied elevational gradients and their underlying climatic factors in constitutive and induced phenolics and volatile organic compounds in Oak trees. Oak defences were measured in leaves in a field study. The dataset includes data for 18 populations of Quercus pyrenaica spanning a 1300 m elevational gradient (from 370 to 1614 m) with their correspondence coordinates. In each population we sampled six saplings that were randomly assigned to one of two treatments:...
