Effects of time since invasion and control actions on a coastal ecosystem invaded by non‐native pine trees

open access: yesEcological Solutions and Evidence, Volume 3, Issue 1, January–March 2022., 2022
Pine invasion reduced native species abundance, plant cover, richness and diversity, with an increase over time since invasion. Species diversity and richness were lower in the managed area than in the area that had not been invaded. Restoration activities are therefore required to increase native species diversity.

The benefits of bivalve reef restoration: A global synthesis of underrepresented species

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 30, Issue 11, Page 2050-2065, November 2020., 2020
Abstract Bivalve habitat restoration is growing in geographic extent and scale globally. While addressing the wide‐scale loss of these biogenic habitats is still a key motivation behind restoration efforts, stakeholders and funders are increasingly drawn to shellfish restoration for the many ecosystem services these habitats provide.

Trophic niche similarities of sympatric Turdus thrushes determined by fecal contents, stable isotopes, and bipartite network approaches

open access: yesEcology and Evolution, Volume 10, Issue 17, Page 9073-9084, September 2020., 2020
Niche dimensions are measurable and describe how species share resources, which has been thought to be a crucial mechanism for coexistence and a major driver of broad biodiversity patterns. Morphologically, similar species of thrushes (Turdus spp.) are generalist species, but distinct, despite overlapping feeding habits allow coexistente.
