Noninvasive measurement of mucosal immunity in a free‐ranging baboon population

Ecoimmunological patterns and processes remain understudied in wild primates, in part because of the lack of noninvasive methods to measure immunity. Secretory immunoglobulin A (sIgA) is the most abundant antibody present at mammalian mucosal surfaces and provides an important first line of defense against pathogens. Recent studies show that sIgA can be measured noninvasively in feces and is a good marker of mucosal immunity. Here we validated a commercial ELISA kit to measure fecal IgA...

Tree functional traits as predictors of microburst-associated treefalls in tropical wet forests

Alana Rader, Amy Cotrell, Anna Kudla, Tiffany Lum, David Henderson & Harshad Karandikar
On 19 May 2018 a microburst caused 600 isolated forest gaps in a Costa Rican tropical forest. We surveyed fallen and standing trees within gaps to determine if certain variables are associated with treefalls. Our results highlight considerations for future research to understand the impacts of microbursts in tropical forests. Our results show that at the scale and locality of our study, treefall vulnerability to microbursts and characteristics of fall events are independent of the...
