To Flee or Not to Flee: How Age, Reproductive Phase, and Mate Presence Affect White Stork Flight Decisions [PDF]

Animals, 2023
Recognizing, assessing, and responding to threats is critical for survival in the wild. Birds, especially in their role as parents, must decide whether to flee or delay flight when threatened.

Diet of breeding Eleonora's falcon Falco eleonorae in Algeria: Insights for the autumn trans‐Mediterranean avian migration [PDF]

Ecology and Evolution, 2022
How environmental changes are affecting bird population dynamics is one of the most challenging conservation issues. Dietary studies of top avian predators could offer scope to monitor anthropogenic drivers of ecosystem changes.

Contrasting effects of agriculture and urbanisation on bird and reptile communities in a Mediterranean delta (Gediz Delta, Türkiye) [PDF]

BMC Ecology and Evolution
Background Wetlands have been some of the most destroyed ecosystems over the last century, with important land-use changes resulting from agricultural, industrial, and urban development.

Fish climbing in the upper Congo Basin (Central Africa), first report for the shellear Parakneria thysi on the Luvilombo Falls [PDF]

Scientific Reports
The ability of shellears to climb waterfalls has been known anecdotally for over 50 years. The behaviour is documented here for the first time, with supporting cinematographic and photographic evidence, for Parakneria thysi climbing the Luvilombo Falls ...

Sky High or Grounded: Nest Site Selection of Herons and Egrets in a Mixed‐Species Colony [PDF]

Ecology and Evolution
Resource partitioning is crucial for the coexistence of colonial herons, as it allows multiple species to share the same habitat while minimising competition.

First record of monogenean fish parasites in the Upper Lufira River Basin (Democratic Republic of Congo): dactylogyrids and gyrodactylids infesting Oreochromis mweruensis, Coptodon rendalli and Serranochromis macrocephalus (Teleostei: Cichlidae) [PDF]

Parasites & Vectors, 2023
Background Monogenean parasites have never been formally reported on fishes from the Lufira River Basin. In this context, we decided to record the monogenean parasite fauna of three cichlid species found in the Upper Lufira River Basin for the first time

Foraging niche shift maintains breeding parameters of a colonial waterbird during range expansion [PDF]

Ecology and Evolution, 2020
Relating the effects of foraging niche variation to reproductive dynamics is critical to understand species response to environmental change. We examined foraging niche variations of the slender‐billed gull (Chroicocephalus genei), a nomadic colonial ...

La restauration des zones humides [PDF]

Houille Blanche, 1996
Apres avoir rappele les definitions et les typologies des zones humides, s'inscrivant pour la plupart dans les bassins versants, nous montrons l'interet ecologique, economique, sociologique de la preservation des zones humides qui apparaissent alors comme des infrastructures naturelles, aux valeurs fonctionnelles et patrimoniales indissociables, devant

Requalifier les zones humides continentales : Logiques et paradoxes

Geocarrefour, 2013
Les nouveaux regards portés sur les zones humides depuis les années 1970, s’ils sont globalement bienveillants, restent multiformes, entre visions biocentriques et utilitaristes, mais s’orientent pleinement vers la reconnaissance de valeurs spécifiques aux zones humides. Se pose alors la question des logiques de requalification – et des instruments qui
