Environmental Benefits from Reduced Pesticide Use and Returns to Research: An Application to the U.S. Cotton Industry [PDF]

open access: yes
Cotton production is one of the main pesticide use industries in the U.S. This intensive use has resulted in the disruption of naturally occurring biological control factors that regulate other insect pest populations and “the pesticide treadmill”.

The effects of climate on bat morphology across space and time

open access: yesEcography, EarlyView.
According to Bergmann's and Allen's rules, climate change may drive morphological shifts in species, affecting body size and appendage length. These rules predict that species in colder climates tend to be larger and have shorter appendages to improve thermoregulation. Bats are thought to be sensitive to climate and are therefore expected to respond to

How many trees are there in the North American boreal forest?

open access: yesEcography, EarlyView.
Boreal forests, the largest terrestrial biome on Earth, are highly varied in local tree density. Despite previous attempts to estimate tree density in boreal forests, the accuracy of the estimation is unknown, leaving the question how many trees there are in boreal forests largely unanswered. Here, we compiled tree density data from 4367 plots in North

Evolutionary trajectories of multiple defense traits across phylogenetic and geographic scales in Vitis

open access: yesEcography, EarlyView.
The processes driving defense trait correlations may vary within and between species based on ecological or environmental contexts. However, most studies of plant defense theory fail to address this potential for shifts in trait correlations across scales.
