Monitoring mosaic biotopes in a marine conservation zone by autonomous underwater vehicle. [PDF]

Conserv Biol, 2019
Abstract The number of marine protected areas (MPAs) has increased dramatically in the last decade and poses a major logistic challenge for conservation practitioners in terms of spatial extent and the multiplicity of habitats and biotopes that now require assessment. Photographic assessment by autonomous underwater vehicle (AUV) enables the consistent

Successional shifts in tree demographic strategies in wet and dry Neotropical forests

Global Ecology and Biogeography, Volume 32, Issue 6, Page 1002-1014, June 2023., 2023
Abstract Aim Tropical forest succession and associated changes in community composition are driven by species demographic rates, but how demographic strategies shift during succession remains unclear. Our goal was to identify generalities in demographic trade‐offs and successional shifts in demographic strategies across Neotropical forests that cover a

Beaching and Natural Removal Dynamics of Pelagic Sargassum in a Fringing‐Reef Lagoon

Journal of Geophysical Research: Oceans, Volume 126, Issue 11, November 2021., 2021
Abstract Massive quantities of the pelagic brown macroalgae Sargassum spp. (sargassum) have been invading the Caribbean and West African shores since 2011, causing devastating effects on the coastal ecosystem and local economy. Little is known about sargassum beaching dynamics and the capacity of the coastal system to naturally remove beached sargassum.

Automated detection of frog calls and choruses by pulse repetition rate

Conservation Biology, Volume 35, Issue 5, Page 1659-1668, October 2021., 2021
Abstract Anurans (frogs and toads) are among the most globally threatened taxonomic groups. Successful conservation of anurans will rely on improved data on the status and changes in local populations, particularly for rare and threatened species.

Detecting early‐warning signals of concern in plant populations with a Citizen Science network. Are threatened and other priority species for conservation performing worse?

Journal of Applied Ecology, Volume 58, Issue 7, Page 1388-1398, July 2021., 2021
The ‘Adopt a plant’ collaborative monitoring programme was launched in NE of Spain to produce standardized indices of abundance change and other early‐warning signals of concern or risk of population collapse. Such information is crucial to report the conservation status of threatened plants, and plants of Community interest (Habitats Directive).

High‐Resolution Observations Unveil (Sub)Mesoscale Heat Fluxes Shaping Upper‐Ocean Heat Content

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Upper‐ocean heat content (UOHC) modulates air–sea exchange in tropical regions; however, its variability at (sub)mesoscale remains insufficiently resolved. Here we combine Surface Water and Ocean Topography (SWOT) observations with high‐resolution glider sections in the northeastern tropical Pacific, where mesoscale eddies and sharp frontal ...

Environmental governance in the face of collapse: The case of Acapulco, Mexico, between tourist splendour and ecological risk

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Underwater clean‐up efforts in Acapulco Bay reveal the visible consequences of chronic coastal pollution. This study shows how Environmental Risk Assessments (ERAs) can integrate scientific evidence, regulatory frameworks and practitioner experience to identify pollution sources and guide more effective coastal governance in cities of the Global South.

Unexpected spatial aggregation between two species of hummingbirds and their inconsistent spatial interactions with native and exotic plants in an urban ecological reserve

Ibis, Volume 167, Issue 4, Page 927-944, October 2025.
Hummingbirds play an important role as pollinators and are one of the primary examples of animal–plant coevolution. However, factors such as land‐use change, urbanization, exotic species introductions and the disappearance of native plants can negatively affect the persistence of hummingbird populations.

Successional Growth Dynamics of Woody Saplings in Tropical Dry Forest Understory

Biotropica, Volume 57, Issue 3, May 2025.
The factors that drive sapling growth in tropical dry forest succession remain unclear. Growth rates are higher in the early stages of succession and then decrease. Light and not water seems to be the main factor limiting sapling growth along succession. The successional guild of species and the taxonomic identity as a Leguminosae were the main factors

Natural forest colonisation as a management strategy to restore soil functioning of abandoned agricultural lands

Journal of Applied Ecology, Volume 61, Issue 11, Page 2690-2700, November 2024.
Though its effectiveness is variable, passive restoration can be more effective than active restoration. Our research indicates that passive tree colonisation of past agricultural land is enough to achieve soil functionality similar to a mature forest for most variables studied. However, some variables would need more time to reach mature forest levels,
