Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

open access: yesEcography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

Interspecific competition among aphid parasitoids: molecular approaches reveal preferential exploitation of parasitized hosts

open access: yesScientific Reports, 2019
When a guild of species exploit the same limited resources, interspecific competition induces the exclusion of inferior competitors, in which case, interspecific recognition mechanisms are needed.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

Influence of Alternative Prey on the Functional Response of a Predator in Two Contexts: With and without Intraguild Predation

open access: yesInsects
In biological control, joint releases of predators and parasitoids are standard. However, intraguild predation (IGP) can occur when a predator attacks a parasitoid, potentially affecting pest control dynamics.

Biocontrol of Xyleborus affinis (Curculionidae: Scolitinae) Females and Progeny by Beauveria bassiana (Hypocreales: Cordycipitaceae) in a Sawdust Artificial Diet Model

open access: yesInsects, 2023
The ambrosia beetle Xyleborus affinis, recently reported affecting avocado trees in Mexico, represents one of the most widespread insects worldwide. Previous reports have shown that Xyleborus genera members are susceptible to Beauveria bassiana and other

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.
