“…Although several species select the same periods in which to harvest floral resources (Santos and Presley 2010;Brito et al 2012), the requirement for specific environmental conditions appears to be more important than interspecific interactions. We showed here that flower visitation to the Malpighiaceae between 11:00 and 13:00 h was clearly low or absent (see too Biesmeijer and Richter 1999;Boas et al 2013). Almeida-Soares et al (2010) observed the visits had unimodal pattern, distinct from the observed by us, but correlated to insolation.…”

“…These two species predominantly received floral visitors with a higher harvesting efficiency, such as Centridini bees. This tribe, which is dominated by individuals with a relatively large body, is classified as one of the leading Malpighiaceae pollinators (Vogel 1988;Alves-dos-Santos et al 2007;Boas et al 2013), and in this study, they visited a larger number of flowers per plant in the shortest time period. This is important for cross-pollination, due to the high mobility of bees between different shrubs and is associated with a high resource collection efficiency (Buchmann 1985;Vogel 1990;Bezerra et al 2009).…”

Spatial and temporal limited resource and niche overlap studies have been widely used to explain resource-sharing in community ecology. Furthermore, morphological and behavioral differences among species are relevant to predict how they may share niche availabilities. We evaluated temporal niche overlap and the ability of visitors to collect floral resources on three Malpighiaceae species in the Brazilian savannah. We hypothesized: (I) an overlap between the temporal niches due the similarities between their floral resources requirements and the temporal limitation of flowering; and (II) a differential ability of bee species in resource harvesting. The 31 floral visitor species exhibited a higher niche overlap than expected by chance, confirming our first hypothesis. Furthermore, according to our second hypothesis, we observed that floral visitors showed a different efficiency in resource collection, depending on bee size and behavior. We believe that this may be a proxy of pollination efficiency. Our discussion is based on the distinct specialization of oil-collecting abilities and the specific requirements of each bee tribe.

“…Among the small-sized bee species visiting Malpighiaceae flowers there is a highly variable range in body size that could generate-at community level-different optimal behaviours that promote the morphological fit of each bee species during flower visits (Vilas-Boas et al 2013;Sazan et al 2014;. The size-efficiency is a factor that potentially structures the floral community as the morphological and behavioural coupling phenomenon was also observed in other trait-behaviour systems, such as those between pollen flowers and buzzing bees (Mesquita-Neto et al 2018).…”

Arthropod-Plant Interactions

In plant-pollination interactions, the antagonists collect the same set of resources offered to legitimate visitors, but their morphologies and behavioural approaches possibly make their effect on plant fitness negative rather than positive. Depending on the morphology of Malpighiaceae flowers, these small-bodied bees can adopt an upside-down position, biting and damaging the floral pedicel. Therefore, we hypothesized that small-bodied bees may reduce female reproductive fitness, due to increased floral abscission. We observed small Tetrapedia bees approaching bagged and unbagged flowers of Peixotoa tomentosa, and compared abscission rates associated with the upside-down behavior performance. When Tetrapedia bees exhibited the upside-down behaviour the floral abscission was about 1.7 times more frequent than without this behaviour. We observed that abscission frequency increased to 80% if upside-down behavior is performed at least three times per flower. Additionally, the frequency of upside-down behaviours were positively related to the number of flowers visited per plant. Overall, the upside-down behaviour of Tetrapedia compromised most flowers that were viable for fruit formation, potentially decreasing the female reproductive fitness of plant population. We emphasize that different roles of floral visitors, including the robbers, are associated with visitors' body size and behaviour. Such features of interactions determine whether floral visitors are pollinators, thieves or robbers and shape a continuum from mutualistic to antagonistic interactions.

“…Originaria de América (BOAS et al, 2013) es de creciente importancia agronómica debido a que crece en suelos pedregosos, arenosos y areno-alcalinos, es eficiente en el uso del agua y es útil para reforestar y restaurar campos infértiles de zonas áridas (FERNÁNDEZ y RIBERO, 2004). El género con mayor número de especies es Byrsonima, con 130 especies (DAVIS y ANDERSON, 2010).…”

REGULADORES DEL CRECIMIENTO Y SUSTRATOS EN LA PROPAGACIÓN VEGETATIVA DE NANCHE (Malpighia mexicana A. Juss. y Byrsonima crassifolia (L) H. B. K.)

RESUMEN -El nanche es un frutal que produce gran parte del año y del que poco se conoce sobre su propagación asexual; por ello, el objetivo de esta investigación fue evaluar el efecto de sustratos, enraizadores y tipo de estacas en la propagacion vegativa de nanche rojo, rosa y amarillo, recolectadas en Santa María Zoquitlán, Oaxaca, México. Se hipotetiza que el uso de reguladores del crecimiento incrementa el enraizamiento y sobrevivencia de estacas. La investigación se realizó en el Colegio de Postgraduados, Campus Montecillo. El experimento 1 fue en primavera-verano, utilizando estacas de 16 cm, 384 apicales y sub-apicales sin hojas, de cada tipo de nanche. Se llenaron charolas de 5 L con turba, agrolita + turba y arena + fibra de coco (3:1 v/v). Las estacas se impregnaron 5 cm de la base con AIB a 3,000, 6,000 y 10,000 ppm, en presentación en polvo y se compararon con un testigo tratado sin AIB. El experimento 2 fue en otoño-invierno, utilizando 108 estacas sub-apicales con tres pares de hojas, de cada tipo de nanche. Como sustrato se usó arena + turba (3:1 v/v) y AIB a 3,000 y 6,000 ppm, un producto comercial Biozyme *TF®, en presentación líquida y un testigo. Las charolas plantadas se cubrieron con bolsas de plástico transparente. El diseño experimental fue en BCA. Se evaluó el porcentaje de sobrevivencia, de brotación y enraizamiento. Los valores se transformaron usando la función arcoseno, se realizó un ANOVA y separación de medias mediante pruebas de Tukey. Las estacas con hojas plantadas en otoño (experimento 2) presentaron mejor sobrevivencia y brotación. El AIB a 6,000 ppm mejoró la brotación de las estacas apicales y el enraizamiento en sub-apicales; el Biozyme *TF® no se recomienda para el enraizamiento. El nanche rojo obtuvo mejor enraizamiento que el rosa y amarillo. Términos para indexación: propagación asexual, auxinas, nanche rojo, nanche rosa, nanche amarillo.

RESUMO -O nanche é uma frutífera que produz grande parte do ano e pouco se sabe sobre sua propagação assexuada; portanto, o objetivo deste trabalho foi avaliar o efeito de substratos, enraizamento em estacas de nanche vermelho, rosa e amarelo, coletadas em Santa Maria Zoquitlán Oaxaca, México. Supõe-se que a utilização de reguladores de crescimento aumentará o enraizamento e a sobrevivencia das estacas caulinares. A pesquisa foi realizada no Colégio de Pós-Graduação, Campus Montecillo. O primeiro experimento foi realizado na primavera-verão, utilizando estacas de 16 cm, 384 apicais e sub-apicais sem folhas, de cada tipo de nanche. Bandejas de 5L foram preenchidas com esfagno, perlita + esfagno e areia + fibra de coco (3:1 v/v). Aproximadamente 5 cm da base das estacas foram impregnados com AIB a 3.000, 6.000 e 10.000 ppm, na forma de talco e um controle. O segundo experimento foi realizado em outono-inverno, usando 108 estacas lenhosas com 3 pares de folhas, de cada nanche. Como substrato foi usado ...
