Climate change and its effects on terrestrial insects and herbivory patterns Neotropical Entomology
Cornelissen,T.
Climate change and extreme weather events affect plants and animals and the direct impact of anthropogenic climate change has been documented extensively over the past years. In this review, I address the main consequences of elevated CO2 and O3 concentrations, elevated temperature and changes in rainfall patterns on the interactions between insects and their host plants. Because of their tight relationship with host plants, insect herbivores are expected to suffer direct and indirect effects of climate change through the changes experienced by their host plants, with consequences to population dynamics, community structure and ecosystem functioning.

ABSTRACT: The objective of this study was to simulate the yield of two cassava cultivars in two IPCC future climate scenarios, the SRES-A1B (Cmip3) and the RCP4.5 (Cmip5), for the state of Rio Grande do Sul, Brazil. The Simanihot model, with the Thornthwaite and Mather water balance sub-model, and the SRES-A1B (Cmip3 - Third Coupled Model Intercomparison Project) and RCP4.5 (Cmip5 - Fifth Coupled Model Intercomparison Project) scenarios of the Fourth and Fifth IPCC Assessment Report, respectively, was used. Cassava cultivars used in this study were 'Fepagro - RS13' (forrage) and 'Estrangeira' (human consumption). In both cultivars, there was an increase in tuberous roots yield in future climate scenarios. The cultivar for human consumption benefits more...

Estimations of leaf CO2 assimilation, stomatal conductance and transpiration in adult Arabic coffee plants after long-term FACE cultivation. Repositório Alice
RAKOCEVIC, M.; BATISTA, E. R.; MATSUNAGA, F. T.; MUNIZ, G..
The air [CO2] can reach 600 ?L CO2 L-1 in the middle or the end of this century, depending on scenario. The first plant response to elevated CO2 (e[CO2]) is the increased leaf photosynthetic rate (A) occurring parallelly by mainly non-sensitive or decreased stomatal conductance (gs) and decreased transpiration (E). In Arabic coffee, A increases under e[CO2], especially during the dry growing season, while gs responses vary during years under free-air-CO2-enrichment (FACE). The aim of this study was to estimate A, gs and E over a coffee vertical profile after five years cultivation under FACE, including the responses to water availability. Coffee was cultivated under two CO2 conditions, actual (a[CO2], ~390?L CO2 L-1) and e[CO2] (~590?L CO2 L-1). The...

Photosynthetic light curve parameters over vertical profile of Coffea arabica plants after five years of FACE experiment. Repositório Alice
RAKOCEVIC, M.; BATISTA, E. R..
Trends in climate changes indicate that the air [CO2] will continue to increase. The first plant response to elevated [CO2] (e[CO2]) is the increased photosynthetic rate. Photosynthetic rate dependence on light (A/PAR curves) is characterized by several parameters, often used to determine plant species responses to environment and phenological plasticity. The effects of water supply and phenological stage were expected, with no acclimation after long-term Coffea arabica L. cultivation under e[CO2]. The aim of the study was to determine variations in parameters of A/PAR curves in coffee leaves over a tree vertical profile after long-term cultivation under free-air-CO2-enrichment (FACE) system. The p arameters of A/PAR curves in C. arabica were estimated...
