Polinizadores Vertebrados: uma visão geral para as espécies brasileiras

Resumo

Desde meados da década de 1990, os polinizadores têm merecido atenção devido à importância que desempenham na manutenção de ecossistemas. Como parte do programa de avaliação do uso sustentável e conservação dos serviços ambientais por polinizadores no Brasil, fizemos o levantamento de 338 espécies de animais vertebrados que são polinizadores efetivos ou potenciais nos principais biomas brasileiros. Há registros de interação destes vetores de pólen com 350 espécies vegetais. No entanto, detectamos desvios na amostragem entre grupos de polinizadores e biomas. Identificamos diversos aspectos a serem incorporados em estudos futuros, tais como amostragens visando à redução dos desvios de observação de grupos de polinizadores e biomas, recuperação de informações provenientes de coleções nacionais e estudos populacionais de longo prazo para avaliação do deslocamento destes animais.

Abstract

Since the middle of 1990, pollinators have received attention because the crucial role they play on ecosystem maintenance. As part of the Brazilian program for sustainable use and conservation of environmental services made by pollinators, we recorded 338 species of vertebrate that can act as effective or potential pollinators on plant species of the main Brazilian biomes. Additionally, interactions between vertebrate and flowers have been recorded for 350 plant species. We detected biases on sampling pollinator groups and biomes, suggesting some aspects that should be incorporated in future surveys in order to reduce the observational bias. Information from national collections must be retrieved to improve the quality of data sets available online. Special attention should be paid to long-term population studies related to the local and regional movements of these animals.
