Drivers of variation in yellow crazy ant (Anoplolepis gracilipes) abundance and impacts on native fauna in an atoll ecosystem

open access: yesConservation Science and Practice, EarlyView.
Yellow crazy ants (Anoplolepis gracilipes; YCA) are widespread invaders of islands across the Pacific and Indian Oceans. We investigated the ecological preferences and impacts of this species on a Polynesian atoll. We show that even at low abundances, this species can have important impacts on the fauna, including seabirds, and require management ...

Comment choisir les espèces pour identifier des réseaux écologiques cohérents entre les niveaux administratifs et les niveaux biologiques ?

open access: yesSciences, Eaux & Territoires, 2018
Les réseaux écologiques sont identifiés comme un outil clé pour allier préservation de la biodiversité et aménagement du territoire. Or ces réseaux sont propres à chacune des nombreuses espèces présentes et se déplaçant sur un territoire.

Integrating ecological feedbacks across scales and levels of organization

open access: yesEcography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Edge Effect on the Distribution of the Green Shield Bug Palomena prasina in Hazelnut Orchards, and the Role of Adjacent Habitats in Crop Colonization

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Spring–Summer spatial dynamics of Palomena prasina (L.) and potential IPM strategies. ABSTRACT Palomena prasina (L.) (Hemiptera: Pentatomidae), the green shield bug (GSB), is an important hazelnut pest in Southern Europe. Currently, its control focuses on insecticide spraying during the crop season. We hypothesized that, as for other pentatomid species,

Pour une analyse pratique des continuités écologiques à diverses échelles de territoire – Exemple de quelques éléments méthodologiques initiés avant la Trame verte et bleue

open access: yesSciences, Eaux & Territoires, 2010
La Direction régionale de l'Environnement, de l'Aménagement et du Logement de Franche Comté nous livre ici quelques réflexions sur des éléments méthodologiques qui ont été éprouvés lors des premiers programmes de mise en œuvre des continuités écologiques.

Anticipating cosmetic emulsion stability using a novel multi‐analytical approach

open access: yesInternational Journal of Cosmetic Science, EarlyView.
A novel combination of granulometry, turbidimetry and rheology enables early detection of cosmetic emulsion instability—reducing assessment time from 30 to 8 days. This rapid method distinguishes stable from unstable emulsions under identical conditions, offering a powerful tool for formulation screening and industrial quality control.

A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

open access: yesJournal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

An updated classification of growth forms in non‐geniculate coralline algae (Corallinophycidae, Rhodophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract The current challenge of defining growth forms in the non‐geniculate coralline red algae was addressed. Since the 19th century, those who have worked on this large and globally distributed group of algae have tried to summarize and systematically describe their growth forms. This effort resulted in a plethora of terms, which could sometimes be

Comparative evaluation of the attractiveness of new polyethylene screens versus West African tiny target for the control of tsetse flies

open access: yesMedical and Veterinary Entomology, EarlyView.
The material has no significant difference in captures (non‐shiny cotton‐polyester screens vs. the shiny polyethylene screens), but the vertical screen attracted significantly more G. tachinoides for each type of material. Full white horizontal screen was significantly lower than the reference WATT.
