For the study in the journal Biotropica, Rice College ecologists and information researchers Daniel Gorczynski and Lydia Beaudrot used thousands of video cam catch pictures to evaluate the large mammal variety in the protected jungle of Costa Rica's Braulio Carrillo Nationwide Park.


In wild animals preservation, variety often describes the variety of species in an community. But ecologists also study functional diversity—the wealth and variant of characteristics such as body dimension, diet, and reproductive rate. Measuring characteristic variety can occur independent of species variety and provide additional understanding about the overall health and wellness of an community.


In the study, Gorczynski and Beaudrot evaluated greater than 4,200 pictures of mammals absorbed the park in between 2007 and 2014 and found the variety of mammal characteristics within the park didn't decrease, despite deforestation that fragmented the woodlands on over half of the bordering private lands.


"It's a little bit of a shock," says Gorczynski, a PhD trainee in the biosciences division. "Previous studies in various other places have revealed that characteristic variety is more conscious human disruption compared to species variety. Characteristic variety can decrease faster compared to species variety, both in situations where species go vanished and where they do not."

There were no mammal extinctions in Braulio Carrillo throughout the 8 years of the study, and Beaudrot, an aide teacher of biosciences, says the characteristic evaluation exposed a degree of functional redundancy that could permit the park's community to proceed functioning also if some of its mammals go vanished in the future.


"It is reputable that national forests protect species, and our outcomes show national forests can be more durable compared to expected, at the very least over the period we analyzed," she says.


Beaudrot says the outcomes are encouraging, but that it would certainly be an error to presume that national forests are as durable as Braulio Carrillo.


"This shows what's feasible, but the circumstance could be very various at various other parks or over much longer time durations," she says. "We need comparable studies for various other parks, various other protected locations, and nonprotected locations.


"This is a location where information scientific research can make a distinction," she says. "Some of the information had to make those contrasts are currently available."
