Animal‐mediated seed dispersal: A review of study methods

Applications in Plant Sciences, Volume 14, Issue 1, January-February 2026.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

High diversity of Phytophthora species in natural ecosystems and nurseries of Portugal: Detrimental side effect of plant introductions from the age of discovery to modern globalization

Plant Pathology, Volume 74, Issue 2, Page 330-362, February 2025.
High diversity of known and new, mostly exotic Phytophthora species in forests, nurseries and streams across Portugal and numerous associated forest tree declines are a consequence of long‐term plant introductions and outplantings. Abstract Between 2010 and 2015, an extensive survey of Phytophthora diversity was performed across Portugal.

Evidence of a twofold ecological trap driven by agricultural change causing a priority farmland bird population crash

Conservation Science and Practice, Volume 6, Issue 10, October 2024.
In this study, we described how the population crash of Montagu's harrier in Portugal is linked with the nationwide abandonment of cereal crops in favor of beef production, which pushes birds into nesting in fodder crops, creating a twofold ecological trap that prevents any breeding output.

Assessing the gut microbiome and the influence of host genetics on a critically endangered primate, the northern muriqui (Brachyteles hypoxanthus)

Environmental DNA, Volume 6, Issue 3, May–June 2024.
Analyses of the microbiome of the critically endangered muriqui revealed the importance of host genetics on the microbiome and suggested that social groups, despite being isolated by environmental barriers, host a similar microbiome composition. Abstract The Northern muriqui (Brachyteles hypoxanthus) is one of the world's most critically endangered ...
