Defensive strategies of neonate nurse sharks, Ginglymostoma cirratum, in an oceanic archipelago of the Western Central Atlantic
(Springer, 2015-06-01)
Two defensive tactics of neonates of nurse sharks, Ginglymostoma cirratum, are reported based on underwater observations. Described as "hiding behaviour" and "substrate resemblance", the defensive ...
Colonization of rocky and leaf pack substrates by benthic macroinvertebrates in a stream in southeast Brazil.
(2008-01-01)
A comparative analysis was conducted of the colonization by benthic macroinvertebrates of rocky and leaf pack substrates, both natural and artificial. This colonization was evaluated by season, with the objective of ...

Structural basis for the relaxed substrate selectivity of Leishmania mexicana broad specificity aminotransferase
(Elsevier Science, 2015-08)
Leishmania species are early branching eukaryotic parasites that cause difficult-to-treat tissue-damaging diseases known as leishmaniases. As a hallmark of their parasitic lifestyle, Leishmaniae express a number of ...
Effects of different substrates on the sprint performance of lizards
(Company of Biologists, 2012-02)
The variation in substrate structure is one of the most important determinants of the locomotor abilities in lizards. Lizards are found across a gradient of habitats from large rocks to loose sand, each of them with ...
Fallen leaves on the water-bed: diurnal camouflage of three night active fish species in an Amazonian streamlet

The Crystal Complex of Phosphofructokinase-2 of Escherichia coli with Fructose-6-phosphate. Kinetic and structural analysis of the allosteric atp inhibition
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2011-02-18)
Substrate inhibition by ATP is a regulatory feature of the phosphofructokinases isoenzymes from Escherichia coli (Pfk-1 and Pfk-2). Under gluconeogenic conditions, the loss of this regulation in Pfk-2 causes substrate ...
