Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (

Probing the Energy Trilemma Pillars: Do Innovation Pathways Deliver Cleaner and More Equitable Energy Systems?

open access: yesSustainable Development, EarlyView.
ABSTRACT Balancing reliable energy supply, equitable access, and environmental sustainability is a central challenge of the global energy transition. This study examines how innovation influences the energy trilemma by shaping energy security, energy equity, and environmental sustainability across 115 countries from 2011 to 2023.

The relative abundance of crop and natural food influences crop consumption by brown bears

open access: yesWildlife Biology, EarlyView.
Many mammalian species now inhabit anthropogenic landscapes, and human–wildlife conflicts, particularly pertaining to crop damage, have become a significant issue. To develop more effective measures to limit crop damage caused by wildlife, it is crucial to identify how natural and anthropogenic food availability affect crop use by wildlife in the ...

La fine del petrolio. Risorse energetiche e democrazia nell'età contemporanea [PDF]

open access: yes, 2010
Siamo agli sgoccioli, letteralmente: per il petrolio si avvicina ormai la fine, e forse troppo tardi si cercano energie alternative. Eppure il petrolio ha una sua storia: celebrato nella prima metà del Novecento come la più importante risorsa ...

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

open access: yesJournal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

Contrasting properties of predation and scavenging networks governed by megaherbivores in an African savannah

open access: yesJournal of Animal Ecology, EarlyView.
For the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.
