The green side of social innovation: Using sustainable development goals to classify environmental impacts of rural grassroots initiatives

open access: yesEnvironmental Policy and Governance, Volume 32, Issue 6, Page 459-477, December 2022., 2022
Abstract Social innovations are grassroots processes aiming to achieve impacts beyond an individual level and towards a broader societal good. The environmental dimension of impacts refers to any direct change to the environment resulting from social innovation activities, products, or services, which are not addressed by pre‐existing systems.

A Novel, Laser‐Based Microsampling Technique for Texturally Controlled, Combined and Complementary Sr and Nd Isotope Measurements in Silicate Minerals

open access: yesGeostandards and Geoanalytical Research, Volume 46, Issue 4, Page 789-809, December 2022., 2022
Key Points LA instruments could offer a non-mechanical alternative for delineating and liberating mineral targets. RM glass proxies demonstrated no significant deviation in parent/daughter analyte mass fractions or 87Sr/86Sr and 143Nd/144Nd ratios after ablation, extraction and chromatography.

Extension and application of an observation‐based local climate index aimed to anticipate the impact of El Niño–Southern Oscillation events on Colombia

open access: yesInternational Journal of Climatology, Volume 42, Issue 11, Page 5403-5429, September 2022., 2022
The here presented modified Tumaco multivariate index (TMI4) has the potential to anticipate the sign and the amount of ENSO‐induced rainfall anomalies over extensive northern and western areas of Colombia (see the significant correlations between TMI4 and rainfall anomalies on the left).

Evidence from accreted seamounts for a depleted component in the early Galapagos plume [PDF]

open access: yes, 2016
The existence of an intrinsic depleted component in mantle plumes has previously been proposed for several hotspots in the Pacific, Atlantic, and Indian Oceans. However, formation of these depleted basalts is often associated with unusual tectonomagmatic

Cyclic Brittle‐Ductile Oscillations Recorded in Exhumed High‐Pressure Continental Units: A Record of Deep Episodic Tremor and Slow Slip Events in the Northern Apennines

open access: yesGeochemistry, Geophysics, Geosystems, Volume 22, Issue 9, September 2021., 2021
Abstract The geological record of deep fossil seismogenesis in subduction zones is limited due to common rock overprinting during exhumation and only a few regions expose well‐preserved deeply exhumed structures. We investigated a mesoscopic contractional duplex formed at blueschist facies conditions in continental metasediments in the Northern ...

Large‐scale patterns of green turtle trophic ecology in the eastern Pacific Ocean

open access: yesEcosphere, Volume 12, Issue 6, June 2021., 2021
Abstract Trophic position and niche width are fundamental components of a species’ ecology, reflecting resource use, and influencing key demographic parameters such as somatic growth, maturation, and survival. Concepts about a species’ trophic niche space have important implications for local management and habitat protection, and can shed light about ...

Biogeography, Systematics, and Ecomorphology of Pacific Island Anoles

open access: yesDiversity, 2019
Anoles are regarded as important models for understanding dynamic processes in ecology and evolution. Most work on this group has focused on species in the Caribbean Sea, and recently in mainland South and Central America.

Scientific note: varroa mite eradication, the strange case of Gorgona Island [PDF]

open access: yesApidologie, 2015
Varroa mites are vectors for several bee viruses contributing also to their diffusion worldwide (Martin 2001; Di Prisco et al. 2011; Cersini et al. 2013). The tripartite relationship among bees, mites, and viruses is thought to be responsible for the loss of a large amount of colonies (Highfield et al. 2009; Berthoud et al. 2010; Francis et al.

The building materials of “Rocca Vecchia” (Old Fortress) in the Gorgona Island

open access: yes, 2022
The research examines the building materials of the ancient fortress known as Rocca Vecchia, in the Gorgona Island, built by the Republic of Pisa and commonly dated to the 13th century. Particular attention is paid to the composition of the artificial stone materials (bricks, bedding mortars, plasters and renders) in order to better understand and ...

Shrinking wings for ultrasonic pitch production: hyperintense ultra-short-wavelength calls in a new genus of neotropical katydids (Orthoptera: tettigoniidae) [PDF]

open access: yes, 2014
This article reports the discovery of a new genus and three species of predaceous katydid (Insecta: Orthoptera) from Colombia and Ecuador in which males produce the highest frequency ultrasonic calling songs so far recorded from an arthropod.
