Interspecific interactions disrupted by roads.

Published in Biological reviews of the Cambridge Philosophical Society

Roads have pervasive impacts on wildlife, including habitat loss and fragmentation, road mortality, habitat pollution and increased human use of habitats surrounding them. However, the effects of roads on interspecific interactions are less understood. Here we provide a synthesis of the existing literature on how species interactions may be disrupt...

Beyond the aggregated paradigm: phenology and structure in mutualistic networks

Published in Journal of Physics: Complexity

Mutualistic relationships, where species interact to obtain mutual benefits, constitute an essential component of natural ecosystems. The use of ecological networks to represent the species and their ecological interactions allows the study of structural and dynamic patterns common to different ecosystems. However, by neglecting the temporal dimens...

Bacterial adenine cross-feeding stems from a purine salvage bottleneck.

Published in The ISME journal

Diverse ecosystems host microbial relationships that are stabilized by nutrient cross-feeding. Cross-feeding can involve metabolites that should hold value for the producer. Externalization of such communally valuable metabolites is often unexpected and difficult to predict. Previously, we discovered purine externalization by Rhodopseudomonas palus...

Sexually transmitted mutualist nematodes shape host growth across dung beetle species

Many symbionts are sexually transmitted and impact their host's development, ecology, and evolution. While the significance of symbionts that cause sexually transmitted diseases (STDs) is relatively well understood, the prevalence and potential significance of the sexual transmission of mutualists remain elusive. Here, we study the effects of sexua...

Inventaire préliminaire des relations entre pucerons myrmécophiles et fourmis des parcelles agricoles en périphérie de l...

Cette étude avait pour objectif de fournir un inventaire préliminaire des interactions entre différentes espèces de fourmis et de pucerons myrmécophiles en périphérie d’Antananarivo. Nous avons identifié cinq espèces de pucerons exotiques, tels que Aphis fabae Scopoli 1763, Aphis citricidus (Kirkaldy 1907), Rhopalosiphum maidis (Fitch 1856), Aphis ...
