“…Biblidinae 3, Charaxinae (4), Morphinae (10), Nymphalinae (2) and Satyrinae (10), with Morpho helenor being the dominant species for eight of the 12 surveyed months. It was interesting to note that none of the strong flyers, such as Morpho and Archaeoprepona (Fruhstorfer, 1915) species, ventured into the other land use types, as Brito et al (2014) suggested that strong flyers would explore different habitats that experienced different levels of disturbance. The dominance of M. helenor in secondary forests can be attributed to the ability of this species to exploit microhabitat conditions (e.g., sunlight patches with contrasting shade for basking and display) and nutritional resources (e.g., Inga sp.…”

“…Each species was placed in one of the following categories: (a) habitat specialist or species that had a single habitat supporting majority of its population: species with Sm > 0.9; (b) species with preference for a particular habitat but not necessarily a specialist of that habitat: species with 0.5 < Sm < 0.9; and (c) habitat generalist or species that had no single habitat supporting majority of its population: species with Sm < 0.5. Only species populations with five or more individuals were used in this calculation as Sm is sensitive to sample size (Brito et al 2014).…”

Tropical forests account for at least 50% of documented diversity, but anthropogenic activities are converting forests to agriculture and urban areas at an alarming rate, with potentially strong effects on insect abundance and diversity. However, the questions remain whether insect populations are uniformly affected by land conversion and if insect conservation can occur in agricultural margins and urban gardens. We compare butterfly populations in tropical secondary forests to those found in sugarcane and urban areas in coastal Guyana and evaluate the potential for particular butterfly communities to inhabit human-modified landscapes. Butterflies were sampled for 1 yr using fruit-baited traps in three separated geographical locations on the coast. We used nonmetric multidimensional scaling to assess differences in species assemblages and a generalized linear mixed model to evaluate abundance, species richness, evenness, and diversity. The secondary forests in all three locations supported higher butterfly abundance and diversity than other human-modified areas, although the magnitude of this effect varied by season and location. However, each land use supported its own type of butterfly community, as species composition was different across the three land uses. Sugarcane field margins and urban gardens supported populations of butterflies rarely found in our tropical secondary forest sites. Land management practices that encourage forest conservation along with butterfly-friendly activities in human settlements and agricultural areas could improve butterfly conservation. To this end, butterfly conservation in Guyana and other tropical landscapes would benefit from a shift from inadvertently to actively making the landscape attractive for butterflies.

“…Specially those butterflies with adaptive morphologies permit foraging flights under a regional scale [24]. It is also expected that species richness of forest specialists increase with increasing connectivity among fragments, as well as with the area of adjacent forest fragments, as already documented for butterflies (see [38]). Large fragments or continuous areas of forest can function as a continent in a source-sink system and the closest fragments as stepping stones (see [39] ) , facilitating the movement of species among fragments in a possible metacommunity dynamic (see [40]).…”

Diversity of fruit-feeding butterflies in a mountaintop archipelago of rainforest

et al. 2017

We provide the first description of the effects of local vegetation and landscape structure on the fruit-feeding butterfly community of a natural archipelago of montane rainforest islands in the Serra do Espinhaço, southeastern Brazil. Butterflies were collected with bait traps in eleven forest islands through both dry and rainy seasons for two consecutive years. The influence of local and landscape parameters and seasonality on butterfly species richness, abundance and composition were analyzed. We also examined the partitioning and decomposition of temporal and spatial beta diversity. Five hundred and twelve fruit-feeding butterflies belonging to thirty-four species were recorded. Butterfly species richness and abundance were higher on islands with greater canopy openness in the dry season. On the other hand, islands with greater understory coverage hosted higher species richness in the rainy season. Instead, the butterfly species richness was higher with lower understory coverage in the dry season. Butterfly abundance was not influenced by understory cover. The landscape metrics of area and isolation had no effect on species richness and abundance. The composition of butterfly communities in the forest islands was not randomly structured. The butterfly communities were dependent on local and landscape effects, and the mechanism of turnover was the main source of variation in β diversity. The preservation of this mountain rainforest island complex is vital for the maintenance of fruit-feeding butterfly community; one island does not reflect the diversity found in the whole archipelago.

“…Los análisis de correlación de Spearman evidenciaron una tendencia positiva de la precipitación con respecto a la riqueza (r=0,39; p=0,0875; n=24; gl=22) y una relación significativa de la precipitación con la abundancia (r=0,5; p=0,00262; n=24; gl= 22). Este patrón de respuesta de la comunidad de mariposas a la precipitación concuerda con lo reportado en múltiples estudios (DeVries, et al, 1997;Shahabuddin & Terborgh, 1999;Hilt, et al, 2007;Luna, et al, 2010;Hussain, et al, 2011;Vargas, et al, 2011;Grøtan, et al, 2012;Sorto, 2013;Brito. et al, 2014;Kishimoto-Yamada & Itioka, 2015;Franzen, et al, 2017;Habel, et al, 2018).…”

El orden Lepidoptera es uno de los taxones más diversos y conocidos de insectos. Sin embargo, hay aspectos ecológicos de este grupo que se han investigado poco en la Orinoquia colombiana. En el estudio se documenta la dinámica temporal de la riqueza y la abundancia de mariposas frugívoras en la sabana inundable del municipio de Arauca y su relación con las variables climáticas de temperatura y precipitación. El muestreo se realizó a 9 km de la cabecera municipal de Arauca, usando seis trampas Van Someren Rydon durante cinco días al mes a lo largo de 24 meses. Se registraron 227 individuos de 21 especies. Los estimadores no paramétricos de diversidad indicaron que el muestreo tuvo una representatividad de 87,9 a 91,2 % de las mariposas frugívoras del área. Los análisis de agrupamiento y de similitudes (ANOSIM) indicaron que la respuesta de la comunidad de mariposas corresponde al régimen unimodal de precipitación de la Orinoquia, con mayor riqueza de especies y abundancia durante los meses de lluvia. Se estableció que las temperaturas en los días de muestreo tuvieron un efecto negativo en las tasas de captura. Este trabajo representa la primera aproximación a la dinámica temporal de la riqueza y la abundancia de lepidópteros y su relación con las variables climáticas en el norte de la Orinoquia colombiana. © 2018.
