Rev. biol. trop; 72 (1), 2024
Abstract Introduction: The River Tambo basin is one of the main hydrographic systems of the Peruvian western watershed, being a source of development for agriculture, agroindustry, livestock, and domestic use in the Tambo Valley and Arequipa City. Objective: To analyze the structure of macroinvertebr...

Ethics and Welfare in invertebrates: a stepping-stone to research and animal production

Rev. biol. trop; 72 (supl.1), 2024
Abstract Introduction: Even though only a few species are considered to be dangerous, pests or vectors, the majority of invertebrates produce a feeling of aversion in humans. This has contributed to the delay in the development of ethical considerations as regards this group in contrast with vertebrate...

Invertebrados (Echinodermata, Brachiopoda, Bryozoa, Cnidaria, Porifera) del Carbonífero de Sierra Santa Teresa, Sonora, México: Consideraciones paleoecológicas y paleogeográficas

Rev. biol. trop; 72 (supl.1), 2024
Resumen Introducción: La Sierra Santa Teresa se encuentra a 20 km al sureste de Hermosillo en la región central del estado de Sonora, México. Los estratos sedimentarios corresponden principalmente a textura de piedra caliza, mudstone, wackestone y packstone del Paleozoico superior. La biota está re...

Benthic community ecology for Algerian river Seybouse

Braz. j. biol; 84 (), 2024
Abstract The Seybouse is the second largest river basin in Algeria, hosting an important biodiversity and providing various ecosystem services. This watershed is highly influenced by agricultural and industrial activities, which threaten its biodiversity and ecosystem integrity. The use of benthic macroi...

Invertebrate dispersal by waterbird species in neotropical wetlands

Braz. j. biol; 84 (), 2024
Abstract Endozoochory by waterbirds is particularly relevant to the dispersal of non-flying aquatic invertebrates. This ecological function exercised by birds has been demonstrated in different biogeographical regions, but there are no studies for the neotropical region. In this work, we identified propa...

The invertebrate paleontology collection at Rio de Janeiro's Museu Nacional: museological practices and stages in its trajectory

Abstract This article examines the general characteristics of how the invertebrate paleontology collection at the National Museum [Museu Nacional] in Rio de Janeiro took shape and the stages in its trajectory, considering the institution's own journey from the perspective of museology and heritage studie...

Características del hábitat que regulan la estructura de las comunidades de macroinvertebrados en ríos tropicales de montaña (Antioquía, Colombia)

Rev. biol. trop; 71 (1), 2023
Introducción: Las comunidades de macroinvertebrados son afectadas simultáneamente por la calidad del agua y las características físicas del hábitat acuático, complicando su uso en la bioindicación. Objetivo: Determinar cuáles variables del hábitat condicionan la comunidad de macroinvertebrados a...

Composición de los macroinvertebrados según la calidad del agua en turberas de altura, Costa Rica

Rev. biol. trop; 71 (1), 2023
Resumen Introducción: En Costa Rica, las turberas de altura se localizan en la Cordillera de Talamanca de 2 400 a 3 200 m. Se forman a partir de depósitos de materia orgánica en descomposición, con oxígeno reducido y baja disponibilidad de nutrientes. Objetivo: Evaluar la variación en la compos...

Bioactividad e identificación de los ácidos grasos de la esponja marina Tetilla rodriguesi (Tetractinellida: Tetillidae) en el Caribe colombiano

Rev. biol. trop; 70 (1), 2022
Resumen Introducción: Durante millones de años, los organismos marinos han venido desarrollando estrategias para adaptarse a los cambios ambientales y con esto, sintetizando una gran variedad de metabolitos secundarios con actividades biológicas. Objetivo: Evaluar las actividades antimicrobiana y anti...

Altitudinal distribution of the functional feeding groups of aquatic macroinvertebrates using an ecological network in Andean streams

Rev. biol. trop; 70 (1), 2022
Abstract Introduction: Analysis of functional feeding groups (FFG) in aquatic macroinvertebrates is important in understanding the structure, function, and dynamics of ecological processes in ecosystems. Modularity refers to the degree of compartmentalization of food webs and varies between -1 and 1. A n...
