Fruit‐quality tradeoffs generate asymmetry in plant reliance on mutualistic frugivores
Oikos, EarlyView.Seed dispersal is a fundamental ecological process influencing the evolution of plant life‐history strategies. In fleshy‐fruited plants dispersed by mutualistic frugivores, variation in fruit traits among closely related species may shape the temporal and spatial dynamics of dispersal events critical to population success.

Coexistence, crossover and extirpation in coalescent communities and ecotones
Oikos, EarlyView.When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...

Transgenic crops with an improved resistance to biotic stresses. A review
Biotechnologie, Agronomie, Société et Environnement, 2015 Introduction. Pests, diseases and weeds (biotic stresses) are significant limiting factors for crop yield and production. However, the limitations associated with conventional breeding methods necessitated the development of alternative methods for ...

Biotic resistance in freshwater fish communities
, 2015 Invasions of non-native species cause problems in ecosystems worldwide, and despite the extensive effort that has been put into research about invasions, we still lack a good understanding for why some, but not other, communities resist these invasions.

Oikos, EarlyView.Droughts, increasingly frequent under human‐driven climate change, are expected to intensify globally. Both pulsed and prolonged droughts can strongly affect organismal survival and population dynamics, potentially altering terrestrial communities and ecosystems.

Oikos, EarlyView.Anthropogenic stressors often co‐occur in ecosystems, but their combined impacts are rarely assessed using field experiments. Press disturbances particularly can reshape community dynamics, altering their capacity to withstand or recover from acute pulse disturbances by modifying response diversity.

Characterization of Fungal Communities Associated with Aquilaria spp. for the Production of Agarwood. [Poster-B123] [PDF]
, 2018 Aquilaria is a tree genus distributed in Southeast Asia, known for its oleoresin production. The induction of this oleoresin is described as a stress reaction by injury and, or fungal infection. In response to this stress, Aquilaria spp.

Oikos, EarlyView.The export of emergent aquatic insects is a critical energy subsidy for terrestrial food webs. While urbanization is known to alter stream communities, its effects on the size structure of these insect subsidies and the subsequent consequences for riparian predators remain poorly understood.
