Mammal defaunation leads to biotic homogenization of plant communities in tropical rainforestsNARA Subscribed
Biotic homogenization is the process in which species communities become increasingly similar across different regions over time. This phenomenon has substantial ecological, evolutionary, and economic implications, primarily driven by human activities such as habitat destruction, invasive species introduction, and climate change. An underexplored driver of biotic homogenization is defaunation, particularly the loss or populati...
Pineapple mealybug wilt-associated viruses 1, 2, and 3 are associated with mealybug wilt disease of pineapple in PeruNARA Subscribed
Mealybug wilt of pineapple (MWP) is the most important disease of pineapple worldwide. During the months of September and November 2020, pineapple production fields of the cultivar Hawaiiana and hybrid MD-2 in Satipo and Chanchamayo provinces of Peru, showed typical symptoms of MWP. Based on symptoms, the disease incidence level ranged between 70 and 90%. Symptomatic and asymptomatic foliar samples were collected and tested by...
Combined simulation and optimization framework for irrigation scheduling in agriculture fieldsNARA Subscribed
In the context of growing evidence of climate change and the fact that agriculture uses about 70% of all the water available for irrigation in semi-arid areas, there is an increasing probability of water scarcity scenarios. Water irrigation optimization is, therefore, one of the main goals of researchers and stakeholders involved in irrigated agriculture. Irrigation scheduling is often conducted based on simple water requireme...
NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the NeotropicsNARA Subscribed
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos,...
ATLANTIC MAMMAL TRAITS : a data set of morphological traits of mammals in the Atlantic Forest of South AmericaNARA Subscribed
Measures of traits are the basis of functional biological diversity. Numerous works consider mean species‐level measures of traits while ignoring individual variance within species. However, there is a large amount of variation within species and it is increasingly apparent that it is important to consider trait variation not only between species, but also within species. Mammals are an interesting group for investigating trai...
Spatio‐temporal rainfall variability in the Amazon basin countries (Brazil, Peru, Bolivia, Colombia, and Ecuador)NARA Subscribed
Rainfall variability in the Amazon basin (AB) is analysed for the 1964–2003 period. It is based on 756 pluviometric stations distributed throughout the AB countries. For the first time it includes data from Bolivia, Peru, Ecuador, and Colombia. In particular, the recent availability of rainfall data from the Andean countries makes it possible to complete previous studies. The impact of mountain ranges on rainfall is pointed ou...
