Dominant predators mediate the impact of habitat size on trophic structure in bromeliad invertebrate communities

…, AAM MacDonald, NAC Marino, PM De Omena… - Ecology, 2015 - Wiley Online Library
Local habitat size has been shown to influence colonization and extinction processes of species
in patchy environments. However, species differ in body size, mobility, and trophic level, …

[HTML][HTML] Extreme rainfall events alter the trophic structure in bromeliad tanks across the Neotropics

…, E Realpe, SL Amundrud, PM de Omena… - Nature …, 2020 - nature.com
Abstract Changes in global and regional precipitation regimes are among the most pervasive
components of climate change. Intensification of rainfall cycles, ranging from frequent …

Constraints on the functional trait space of aquatic invertebrates in bromeliads

…, VD Pillar, DS Srivastava, PM de Omena… - Functional …, 2018 - Wiley Online Library
Functional traits are commonly used in predictive models that link environmental drivers
and community structure to ecosystem functioning. A prerequisite is to identify robust sets of …

Food web structure shaped by habitat size and climate across a latitudinal gradient

GQ Romero, GCO Piccoli, PM de Omena… - Ecology, 2016 - Wiley Online Library
Habitat size and climate are known to affect the trophic structure and dynamics of communities,
but their interactive effects are poorly understood. Organisms from different trophic levels …

Warming weakens facilitative interactions between decomposers and detritivores, and modifies freshwater ecosystem functioning

TN Bernabé, PM de Omena, VP Santos… - Global change …, 2018 - Wiley Online Library
Warming is among the major drivers of changes in biotic interactions and, in turn, ecosystem
functioning. The decomposition process occurs in a chain of facilitative interactions …

Warming of aquatic ecosystems disrupts aquatic–terrestrial linkages in the tropics

…, GQ Romero, PM de Omena… - Journal of Animal …, 2021 - Wiley Online Library
Aquatic ecosystems are tightly linked to terrestrial ecosystems by exchanges of resources,
which influence species interactions, community dynamics and functioning in both ecosystem …

Geographical variation in the trait‐based assembly patterns of multitrophic invertebrate communities

…, O Dézerald, IM Barberis, PM de Omena… - Functional …, 2023 - Wiley Online Library
It has been argued that the mechanisms structuring ecological communities may be more
generalizable when based on traits than on species identities. If so, patterns in the assembly of …

Ecological response to altered rainfall differs across the Neotropics

…, R Freire, E Realpe, SL Amundrud, PM de Omena… - Ecology, 2020 - Wiley Online Library
There is growing recognition that ecosystems may be more impacted by infrequent extreme
climatic events than by changes in mean climatic conditions. This has led to calls for …

Using visual cues of microhabitat traits to find home: the case study of a bromeliad-living jumping spider (Salticidae)

PM De Omena, GQ Romero - Behavioral Ecology, 2010 - academic.oup.com
There are many examples of predators having specialized microhabitat requirements, but
the sensory mechanisms by which predators detect, identify, and evaluate microhabitats are …

Fine-scale microhabitat selection in a bromeliad-dwelling jumping spider (Salticidae)

PM De Omena, GQ Romero - Biological Journal of the Linnean …, 2008 - academic.oup.com
Although a wide variety of arthropods specialize on a specific host plant, little is known about
the evolution of host–plant specialization in spiders. In several regions of South America, …
