“…Starr & Sakagami (1987) stated that the nest entrance of T. sapiens and T. fuscobalteata are tube-like with many variations of texture, diameter, and length. Variation of nest entrances related to defense and foraging activities of stingless bees (Biesmeijer et al 2005).…”

Stingless bees (Hymenoptera: Apidae) is eusocial insects that live together in a colony. This research was aimed to study the nesting site characteristics of stingless bees in the settlement areas at Central Sulawesi, Indonesia. The nesting sites were observed by purposive sampling method from July 2015 to January 2016. Four species belong to genus Tetragonula were found, namely T. fuscobalteata, T. biroi, T. sapiens, and T. laeviceps. Two spesies, T. biroi and T. sapiens are the new record in Sulawesi island. The highest abundance of stingless bees colony was T. fuscobalteata (92.26%), followed by T. biroi (4.17%), T. sapiens (2.98%), and T. laeviceps (0.59%). Nesting sites of T. fuscobalteata were found in the stone, brick wall, wooden wall, bamboo, and iron cavities, T. biroi in the wooden wall, stone, and brick wall cavities, T. sapiens in stone cavities, while T. laeviceps in wooden walls.

“…Many pollinator insects have an innate preference for symmetric and disruptive patterns (Rodríguez and Gumbert, 2004). Moreover, floral guides, stingless bee nest entrances and insectivorous pitchers all exhibit a similar dark center, radiating stripes and peripheral dots (Biesmeijer et al, 2005). The arrangement of body color patches on N. pilipes and their differential visual distinctiveness to insects may be because the overall signal resembles the aforementioned global visual attributes of a pollinator's resource.…”

SUMMARY While animal color signaling has been studied for decades, we have little knowledge of the role conspicuous body coloration plays in the nocturnal context. In this study we explored animal color signaling in both diurnal and nocturnal contexts to arrive at a more comprehensive understanding of its function. We quantified how the brightly colored giant wood spiders Nephila pilipes are viewed by nocturnal insects, and performed field manipulations to assess the function of a spider's coloration in both diurnal and nocturnal conditions. Seen through the eyes of moths, the conspicuous body parts of spiders are quite distinctive from the vegetation background. The presence of N. pilipes significantly increased the diurnal as well as the nocturnal prey interception rates of their webs, but these rates were significantly reduced when the conspicuous color signals of N. pilipes were altered by black paint. A comparison of the diurnal and nocturnal hunting performances of spiders showed that their conspicuous coloration had a higher luring effect under dim light conditions. These results demonstrate that the conspicuous body coloration of N. pilipes functions as a visual lure to attract both diurnal and nocturnal prey. It seems that nocturnal insects are the major target of this colorful sit-and-wait predator. We suggest that the selection pressure to effectively exploit the color vision of nocturnal prey could be one of the major forces driving the evolution of spider coloration.

“…Cipura paludosa possui atributos florais supostamente atrativos às abelhas, tais como antese diurna, presença de áreas de emissão de odor, cor lilás, plataforma de pouso (tépalas), guia indicadores de recurso e centro floral diferenciado das demais partes da flor (Faegri & Van der Pijl 1979;Biesmeijer et al 2005). Apesar do conceito de sindromes ser discutível, e sua utilização está relacionada a possível predição da existência de grupos principais de polinizadores (Rosas-Guerrero et al 2014mas ver Ollerton et al 2011), para C. paludosa a ocorrência de abelhas como únicos polinizadores corroboraram com as características florais observadas.…”

Biologia reprodutiva e flores de óleo em Cipura paludosa (Iridaceae)

et al. 2016

ResumoCipura paludosa está inserida na família Iridaceae a qual se destaca pela grande diversidade de sistemas de polinização, ofertando recursos como néctar, pólen e óleo. Esse estudo foi conduzido em um fragmento de Mata Atlântica em área urbana, em Recife, Pernambuco. O trabalho teve como objetivo investigar a biologia floral e reprodutiva da herbácea C. paludosa. Foi avaliado o período de abertura floral, receptividade estigmá-tica, deiscência das anteras, número de grãos de pólen e óvulos por flor, morfometria floral, experimentos de autopolinização espontânea e de polinização natural, além da observação de visitantes florais. Cipura paludosa é melitófila, autocompatível, oferece pólen e óleo (produzido em elaióforos tricomados) como recursos e recebe visitas de Plebeia sp. e Augochlora thalia. Por formar poucos frutos espontaneamente, C. paludosa se beneficia dos serviços de polinização para o seu sucesso reprodutivo. A ocorrência de abelhas não especialistas na coleta de óleo pode levar a má qualidade nos serviços de polinização, reduzindo a aptidão da espécie. Palavras-chave: Elaióforos tricomados, serviços de polinização, abelhas não especializadas, autocompatibilidade, Mata Atlântica. AbstractCipura paludosa is taxonomically placed in the Iridaceae family which is notable for the diversity of pollination systems, offering resources such as nectar, pollen and oil. The study was conducted within a fragment of Atlantic Forest in Recife, Pernambuco, to investigate the floral and reproductive biology of C. paludosa. The floral opening period, stigmatic receptivity, anther dehiscense, number of pollen grains, ovules per flower and floral morphology were evaluated; experiments regarding to the reproductive system and flower visitor observations were performed. Cipura paludosa is a herbaceous plant with melittophilous and self--compatible flowers, visited by Plebeia sp. and Augochlora thalia. The flower resources produced by C. paludosa were pollen and oil (produced in trichomal elaiophores). To ensure reproductive success Cipura paludosa benefits from pollination services since it produces only a few fruits spontaneously. The presence of bees not specialized in oil collecting may result in poor quality pollination services consequently reducing the species reproductive output.
