Diversity and vertical distribution of psocids (Psocodea: Psocoptera) in two forests of the Colombian Amazon

Rev. biol. trop; 68 (3), 2020
Introduction: The knowledge on the diversity of psocids in Colombia has increased, following the global trend, but the main interest of most of the studies has been oriented to solve taxonomic aspects, leaving aside other biological aspects, of which little is known, such as the ecological interactions o...

Colonización de macroinvertebrados acuáticos en tres tipos de sustratos artificiales, en un río tropical

Rev. biol. trop; 68 (supl 2), 2020
Introducción: Existen diferentes metodologías para la recolecta de macroinvertebrados acuáticos (p.e., la red D y Red Surber), sin embargo, algunas de estas no son efectivas en todos los cuerpos de agua o representa un riesgo para la persona que adquiere la muestra. Los sustratos artificiales pueden e...

Morphological characterization of insect galls and new records of associated invertebrates in a Cerrado area in Bahia State, Brazil

Braz. j. biol; 78 (4), 2018
Abstract In this study, we report the first records and morphological characterization of galls in a Cerrado area in western Bahia, Brazil. The data were collected monthly over two hours between March and September 2015. Fifteen gall morphotypes were found in twelve plant species distributed among seven ...

Insect Galls of the Parque Nacional do Itatiaia (Southeast Region, Brazil)

An. acad. bras. ciênc; 89 (1,supl), 2017
ABSTRACT The Parque Nacional do Itatiaia (PNI) (Brazilian Southeast Region) was surveyed monthly for insect galls from February/2014 to December/ 2015. A total of 432 gall morphotypes were found. This number places the PNI as the richest Atlantic forest area in number of gall morphotypes. The galls were ...

Insect galls of Restinga de Marambaia (Barra de Guaratiba, Rio de Janeiro, RJ)

Braz. j. biol; 76 (3), 2016
Abstract Thirty-one morphotypes of insect galls and two flower damages were found on 16 families, 22 genera and 24 plant species in Restinga de Marambaia (Barra de Guaratiba, Rio de Janeiro, RJ). Fabaceae and Myrtaceae were the plant families with the greatest richness of insect galls (4 and 6 morphotype...

Resource allocation in Copaifera langsdorffii (Fabaceae): how supra-annual fruiting affects plant traits and herbivory?

Rev. biol. trop; 64 (2), 2016
AbstractPlants have limited resources to invest in reproduction, vegetative growth and defense against herbivorous. Trade-off in resources allocation promotes changes in plant traits that may affect higher trophic levels. In this study, we evaluated the trade-off effect between years of high and low frui...

Effects of habitat management on different feeding guilds of herbivorous insects in cacao agroforestry systems

Rev. biol. trop; 64 (2), 2016
AbstractHuman pressure on natural habitats increases the importance of agroforests for biodiversity conservation. The objective of this study was to evaluate the role of cacao traditional cultivation system (CTCS) on the conservation of the herbivorous insect community when compared with a monodominant r...
