Testing the contribution of vertebrate predators and leaf traits to mainland–island differences in insect herbivory on oaks

Journal of Ecology, Volume 113, Issue 1, Page 140-154, January 2025.
The authors explored how insularity influences herbivory in oaks across island–mainland sites. By experimentally excluding vertebrate predators (e.g. birds, bats) and measuring leaf traits (e.g. phenolics, specific leaf area, nutrients), they provide insights into the mechanisms driving island–mainland herbivory patterns.

A review of commercial captive breeding of parrots as a supply‐side intervention to address unsustainable trade

Conservation Biology, Volume 38, Issue 5, October 2024.
Abstract The volume and scale of commercial captive breeding of parrots have grown dramatically in recent decades. Although it has been proposed, and is often assumed, that captive breeding can reduce pressure on wild populations, there has been little scrutiny of the scale, viability, or impacts of captive breeding to prevent overexploitation among ...

Sexual maturity of the deep-sea royal crab Chaceon ramosae Manning, Tavares & Albuquerque, 1989 (Brachyura: Geryonidae) in southern Brazil Madurez sexual del cangrejo real Chaceon ramosae Manning, Tavares & Albuquerque, 1989 (Brachyura: Geryonidae) en el sur de Brasil

Latin American Journal of Aquatic Research, 2009
The royal crab Chaceon ramosae is one of the three species of deep-sea crabs currently exploited in Brazil. The royal crab fishery started in 2001 with foreign vessels that were extensively monitored by observers and tracked by satellite.

Soil carbon and nitrogen cycling at the atmosphere–soil interface: Quantifying the responses of biocrust–soil interactions to global change

Global Change Biology, Volume 30, Issue 10, October 2024.
Despite the critical role of biological soil crusts (biocrusts) in dryland C and N cycles, little is known about how biocrust‐derived C and N move into the soil. This study reveals how biocrusts facilitate the downward movement of C and N and drive the formation of mineral‐associated organic matter in subcrust soils.

Latin American Journal of Aquatic Research, 2009
The red crab Chaceon notialis is one of the three deep-sea crab species currently exploited in Brazil. The red crab fishery started in 1998 with foreign vessels that, as of 2000, have been extensively moni-tored by observers and tracked by satellite.

Bacillus mycoides y ácidos húmicos como bioestimulantes de fríjol caupí bajo estrés por salinidad

Revista U.D.C.A Actualidad & Divulgación Científica, 2022
Los bioestimulantes tienen gran potencial en la agricultura, no solo por aumentar el crecimiento de las plantas, sino porque también promueven la tolerancia frente a diferentes tipos de estrés. En este estudio, se evaluó el efecto de dos bioestimulantes

Geographic variation in developmental plasticity among populations of the canyon treefrog in response to temperature and pond‐drying

Journal of Zoology, Volume 324, Issue 2, Page 103-117, October 2024.
This study focuses on the responses of the canyon tree frog (Dryophytes arenicolor) larvae to temperature and pond‐drying. Conducting a common garden experiment with larvae from three distinct populations, we found significant geographic variation in plastic responses and observed that populations exhibit specific responses to each treatment in both ...
