Effect of land use change on Melolonthidae (Coleoptera: Scarabaeoidea) beetle communities in the deforestation arc of the Brazilian Amazon

open access: yesInsect Conservation and Diversity, EarlyView.
Habitat transformation in Amazon due to agriculture expansion impairs Melolonthidae diversity. Assemblage response towards habitat transformation are group‐dependent. Although highly disturbed, Amazon arc of deforestation region dwells sensitive insect assemblages. Abstract Although the Amazon provides crucial goods and ecosystem services for humanity,

Phosphorylation of phosphoenolpyruvate carboxykinase in plants. Studies in plants with C4 photosynthesis and Crassulacean acid metabolism and in germinating seeds [PDF]

open access: yes, 1996
We have previously shown that phosphoenolpyruvate carboxykinase (PEPCK) is phosphorylated in vivo in the cotyledons of darkened cucumber seedlings and that phosphorylation is reversed by light [Walker and Leegood (1995) FEBS Lett. 362, 70–74].

Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).

Repeatability, Genetic Variability and Importance of Forage Traits in Ecotypes of Brunswickgrass (Paspalum nicorae Parodi) via BLUP

open access: yesPlant Breeding, EarlyView.
ABSTRACT This study estimated the repeatability of forage traits in 84 Paspalum nicorae ecotypes using six statistical methods and quantified the minimum number of harvests needed for effective selection. Multivariate analyses based on best linear unbiased prediction (BLUP) values were also performed to assess genetic variability, identify key traits ...

Tripartite Symbiosis Between Legumes, Arbuscular Mycorrhizal Fungi and Nitrogen Fixing Rhizobia: Interactions and Regulation

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Legume plants can interact with nitrogen‐fixing rhizobia bacteria and arbuscular mycorrhizal fungi (AMF) simultaneously, forming a tripartite symbiotic association. Co‐inoculation studies performed on a variety of legumes have shown that rhizobia and AMF influence each other when they co‐occur in tripartite association and affect host plant ...
