Foliar nutrient levels of native tree species from Central Amazonia. 2. Campina

open access: yes, 1985
Adult leaves of 14 woody species were sampled in the campina at km 62 of the road Manaus - Caracaraí. The lamina were classified as to their size and analysed for N, P, K, Ca, Mg and Na. Comparing the foliar levels of the bioelements to relevant data for

Analysis of phenotypic plasticity in response to water constraints in coffee plants growing under field conditions [PDF]

open access: yes, 2008
In a context of climate change, adaptation of perennial plantations to water constraints becomes a major concern for wood and fruit productivity. Adaptation depends on the level of genetic diversity in breeding and natural populations, as well as their ...

Controlled Movement of Soft Actuators using Multi‐Responsive Microgel Arrays and Microcirculatory Systems

open access: yesAdvanced Functional Materials, EarlyView.
Microscale hydrogels (microgels) feature improved mass transport characteristics supportive of fast actuation and chemical tunability amenable to programmed stimuli response. A unique soft actuator architecture is realized by encapsulating microgels in soft microcirculatory systems which enable the convenient delivery of liquid stimuli for powering and
