DNA mini-barcoding of leporids using noninvasive fecal DNA samples and its significance for monitoring an invasive species. [PDF]

Ecol Evol, 2020
In South America, the European hare is considered an invasive species, representing a risk to native Brazilian forest rabbits. Monitoring the invasive European hare and its coexistence with native forest rabbits is a challenge that can be efficiently addressed by the use of molecular tools.

Enhancement of conservation knowledge through increased access to botanical information. [PDF]

Conserv Biol, 2019
Abstract Herbarium specimens are increasingly recognized as an important resource for conservation science and virtual herbaria are making specimens freely available to a wider range of users than ever before. Few virtual herbaria are designed with conservation use as a primary driver. Exceptionally, Brazil's Reflora Virtual Herbarium (RVH) was created

Sleeping accommodations for researchers increase the likelihood of biodiversity inventories in protected areas 在保护区内为科研人员提供住所，可增加创建生物多样性名录的可能性

Integrative Conservation, Volume 2, Issue 1, Page 62-68, March 2023., 2023
Biodiversity assessments are needed to better understand biodiversity distribution and threats in parks. Our results showed that arthropod inventories are more likely if park accommodations are available for researchers. Small investments in providing accommodations may increase biodiversity assessments in parks.

Effects of forest degradation on Amazonian ferns in a land‐bridge island system as revealed by non‐specialist inventories

Ecological Solutions and Evidence, Volume 3, Issue 1, January–March 2022., 2022
Tropical forests have been rapidly deforested and degradation worldwide has outpaced biodiversity field sampling. We here show that a simple sampling protocol carried out by a non‐specialist can lead to inexpensive and highly reliable ecological data.
