A conceptual framework for studying the strength of plant-animal mutualistic interactions
(Blackwell Publishing Ltd, 2015)
© 2015 John Wiley & Sons Ltd/CNRS.The strength of species interactions influences strongly the structure and dynamics of ecological systems. Thus, quantifying such strength is crucial to understand how species interactions ...
Cryptic interactions revisited from ecological networks: Mosses as a key link between trees and hummingbirds
(Wiley, 2020)
1. Ecological interactions are the glue of biodiversity, structuring communities and
determining their functionality. However, our knowledge about ecological interactions
is usually biased against cryptic interactions ...
Ecological consistency across space: A synthesis of the ecological aspects of Dromiciops gliroides in Argentina and Chile
(2012)
Dromiciops gliroides is an arboreal marsupial found in the temperate forests of South America (36- 43 °S). This species is the sole extant representative of the order Microbiotheria, and is a key seed disperser of many ...
Why mistletoes are more aggregated in disturbed forests? The role of differential host mortality
(Elsevier B.V., 2017)
© 2017 Elsevier B.V. Mistletoes rely on biotic seed dispersal to ensure their recruitment on appropriate host plants, as their seeds must be deposited on safe sites to allow attachment. As most host-parasite systems, ...
Plant-mammal interactions in tropical Bolivian forests with different hunting pressures
(2001)
We studied plant-animal interactions and vegetation structure in two geographically close tropical Bolivian forests subjected to different hunting intensities. We hypothesized that reduction of mammals of > 1 kg in an ...
Ecology and evolution of negative and positive interactions in Cactaceae: Lessons and pending tasks
(2012)
Background: The Cactaceae is a diverse and conspicuous Neotropical family that has evolved a wide variety of adaptations during co-evolution with their interacting species. Recent research has indicated complex ecological ...
Increased resource availability prevents the disruption of key ecological interactions in disturbed habitats
(Ecological Society of America, 2017)
© 2017 Fontúrbel et al. Anthropogenic disturbance can modify habitat structure and resource availability, potentially disrupting ecological interactions. This issue may be critical for pollination and seed dispersal, which ...
Indirect interactions in a microcosm-assembled cladoceran community: Implications for apparent competition
(2002)
Apparent competition occurs when species that otherwise may not directly interact still exhibit negative indirect effects on one another because they share a food-limited predator (enemy). Even though this type of indirect ...
Heterospecific Vocal Interactions in a Frog from the Southern Temperate Forest, Batrachyla taeniata
(2011)
Animals using sound communication employ different strategies to overcome interferences from biotic and abiotic sources. However, interactions among acoustically active species have been studied to a very limited extent. ...
Interactions between males of the lizard Liolaemus tenuis: Roles of familiarity and memory
(2002)
For territorial organisms, recognition of familiar individuals can reduce the frequency and intensity of aggressive encounters ('dear enemy' phenomenon), stabilize social systems, and reduce the cost of territory maintenance. ...
