Seasonal effects of farmer-managed livestock grazing exclusions on bird communities in Burkina Faso. [PDF]

Ecol Appl
Abstract Anthropogenic activities such as livestock grazing and deforestation are primary causes of land degradation in drylands such as the Sahel Zone of Africa, threatening the livelihoods of rural communities and biodiversity. To restore degraded habitats, measures such as farmer‐managed livestock grazing exclusion, where the native vegetation is ...

Exposure of wetlands important for nonbreeding waterbirds to sea-level rise in the Mediterranean. [PDF]

Conserv Biol
Abstract Sea‐level rise (SLR) is expected to cause major changes to coastal wetlands, which are among the world's most vulnerable ecosystems and are critical for nonbreeding waterbirds. Because strategies for adaptation to SLR, such as nature‐based solutions and designation of protected areas, can locally reduce the negative effects of coastal flooding

Precipitation gradients drive high tree species turnover in the woodlands of eastern and southern Africa

Ecography, Volume 2023, Issue 10, October 2023., 2023
Savannas cover one‐fifth of the Earth's surface, harbour substantial biodiversity, and provide a broad range of ecosystem services to hundreds of millions of people. The community composition of trees in tropical moist forests varies with climate, but whether the same processes structure communities in disturbance‐driven savannas remains relatively ...

Migrating bars influence the formation and dynamics of their peers in large sandy‐gravel bed rivers

Earth Surface Processes and Landforms, Volume 48, Issue 8, Page 1512-1525, 30 June 2023., 2023
This study investigates the interactions between migrating bars in a sandy gravel river (Loire River, France). We analysed the deflection power exerted by bars on flow and sediment transport that influences the dynamics of other bars present in the channel. We also investigated the role of low flows in bar formation and migration.

Global historical trends and drivers of submerged aquatic vegetation quantities in lakes

Global Change Biology, Volume 29, Issue 9, Page 2493-2509, May 2023., 2023
Submerged aquatic vegetation (SAV) in lake littoral zones provide many ecosystem services, but what are the trends and drivers of SAV quantities globally? SAV quantities are predominantly decreasing due to land use change with increasing trends being more recent and associated with management and invasive species.

Building spaces of interactions between researchers and managers: Case studies with wildlife monitoring and conservation in France

Ecological Solutions and Evidence, Volume 4, Issue 2, April–June 2023., 2023
Abstract To document and halt biodiversity loss, monitoring, quantifying trends and assessing management and conservation strategies on wildlife populations and communities are crucial steps. With increasing technological innovations, more and more data are collected and new quantitative methods are constantly developed.

Young Allis Shad Alosa alosa (Clupeidae) Would Not Be Euryphagous: An Assessment of Juvenile Diet and Prey Selectivity under Riverine‐Type Conditions

Journal of Applied Ichthyology, Volume 2023, Issue 1, 2023., 2023
Allis shad Alosa alosa hatches and develops in freshwater before migrating to the sea during its first months of life. Some field research works dedicated to the diet of the species in freshwater put forward that young stages of allis shad feed mainly on zooplankton, being opportunistic and euryphagous; their diet would diversify through ontogeny in ...

Coping with environmental constraints: Geographically divergent adaptive evolution and germination plasticity in the transcontinental Populus tremuloides

PLANTS, PEOPLE, PLANET, Volume 4, Issue 6, Page 638-654, November 2022., 2022
Syntheses clearly show that global warming is affecting ecosystems and biodiversity around the world. New methods and measures are needed to predict the climate resilience of plant species critical to ecosystem stability, to improve ecological management and to support habitat restoration and human well‐being.
