(PDF) A headstarting programme for the Critically Endangered Manapany day gecko Phelsuma inexpectata on Réunion Island PDF | The Manapany day gecko Phelsuma inexpectata has experienced drastic population declines over the past decade in its native range on Réunion... | Find, read and cite all the research you need on ...

We established the first local headstarting programme for Phelsuma day geckos, providing a critical conservation tool to secure the long-term persistence of a Critically Endangered species and a model for managing other threatened Phelsuma across the region.

Schematic diagram of the influence of seabirds on temperate and tropical near-shore marine systems. Temperatre systems: - Nutrient enrichment and predation on herbivorous invertebrates can lead to increased algal production - Phytoplankton communities change, featuring more large-celled species - Intertidal organisms incorporate seabird-enriched material by grazing on detritus and biofilm in tidepools - Macroalgae biodiversity and primary production are boosted Tropical systems: - Mangrove leaf nutritional quality increases - Corals recover faster after bleaching events - Fish biomass increases across different trophic groups - Pelagic and benthic consumers' foraging behaviour shifts - Parrotfish grazing and bioerosion rates increase - Fish grow larger

Thank you.

The Yellow crazy ant Anoplolepis gracilipes, introduced on Reunion Island since the late 17th century, has recently emerged as a new and possibly significant threat to the Critically Endangered Manapany day gecko Phelsuma inexpectata. 🦎🌿🧪
