Clustering of Rainfall Stations in RH‐24 Mexico Region Using the Hurst Exponent in Semivariograms
Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 An important topic in the study of the time series behavior and, in particular, meteorological time series is the long‐range dependence. This paper explores the behavior of rainfall variations in different periods, using long‐range correlations analysis.

Use and Diversity of Palm (Arecaceae) Resources in Central Western Brazil
The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 Arecaceae Schultz‐Sch. (Palmae Juss.), a member of the monocotyledon group, is considered one of the oldest extant angiosperm families on Earth. This family is highly valuable because of its species diversity, its occurrence in a wide range of habitats, and its status as an integral part of the culture and the family‐based economy of many traditional ...

Mycorrhizal Interactions for Reforestation: Constraints to Dryland Agroforest in Brazil
International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011 Reforestation provides restoration of forest ecosystem services including improved soil fertility, which leads to increased productivity and/or sustainability of the system. Trees also increase the average carbon stocks providing wood supply for local communities; however, C sequestration strategies highlight tree plantations without considering their ...

Pest Management Science, Volume 82, Issue 4, Page 3395-3407, April 2026.Chemical profiling and bioassays reveal that leaf‐litter leachates from urban trees flip between nourishing and killing Aedes aegypti larvae: dilute Tipuana tipu boosts growth, whereas concentrated, aged extracts are >90% lethal. Species‐specific chemistry thus turns street trees into potential self‐renewing tools for integrated vector control ...
