Digitising biological collections to advance National Species Inventories: A case study from the flora of Chile

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
In response to Chile's public policy to establish a national biodiversity inventory and monitoring system, we launched the HerbarioDigital.cl portal. We have digitised over 120,000 specimens representing more than 3,900 species from two Chilean herbaria, integrating them through a curated local taxonomic index.

Roadkill data reveal new distribution records and possible range shifts for neotropical mammals

open access: yesDiscover Conservation
Roads are expanding rapidly across biodiverse regions, including global biodiversity hotspots such as the Tropical Andes and the Chocó/Darién. While roads improve connectivity for human populations, they also lead to significant biodiversity loss through

Updating the distribution of the Sierra Madre Sparrow Xenospiza baileyi across central Mexico: historical records, new localities, and conservation perspectives

open access: yesAvian Conservation and Ecology, 2020
The Sierra Madre Sparrow (Xenospiza baileyi) is an endangered species microendemic to subalpine grasslands of central and northwestern Mexico. Given that land use change is highly dynamic in central Mexico, there is a need for a continuous monitoring of ...

Knee height is often right: evaluating device height effects on camera trapping rate

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Camera trap deployment height can introduce systematic biases in detection trapping rates across species of different body sizes. Combining 172 paired sampling points in five experiments across Europe, North America and Africa, our results show that low cameras significantly increase detections of small‐ and medium‐sized species, whereas high cameras ...

Red meat and egg intake and serum ferritin concentrations in Colombian children: results of a population survey, ENSIN-2015

open access: yesJournal of Nutritional Science, 2020
The present study aimed to (a) establish the frequency of consumption of red meat and eggs; (b) determine serum ferritin levels (μg/l); and (c) establish the relationship between serum ferritin and the consumption of red meat and eggs. In Colombia during

As above, so below: A perspective into the application of land‐forest monitoring methods for the assessment of marine animal forests

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Marine animal forests (MAFs) are benthic ecosystems dominated by vertically structuring filter‐ and suspension‐feeders. As terrestrial forests, they are considered biodiversity hotspots, forming canopies, serving as a refuge, nursery, reproduction and feeding shelters for many species.

Multicriteria evaluation and remote sensing approach to identifying degraded soil areas in northwest Peru

open access: yesGeocarto International
Soil is a vital nonrenewable resource characterized by rapid degradation and slow regeneration processes. In this study, soil degradation in Jaén and San Ignacio was assessed via a multicriteria evaluation approach combined with remote sensing (RS) data.

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

open access: yesConservation Biology, EarlyView.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.
