Abundance And Diversity

Frugivorous butterflies were studied in a set of forested islands (0.1 to 1.15 ha) in a reservoir in eastern Venezuela to investigate the effects of fragmentation and the resulting isolation on their abundance, diversity and species composition. While some islands showed reduced abundance and species diversity in comparison to unfragmented (or control) sites, others did not. Isolation status affected both butterfly abundance and diversity. Islands located close to their colonizing sources (0.1–1 km) tended to support similar densities of butterflies but lower numbers of species in comparison to control sites. Far fragments (1–3 km from their colonizing sources) tended to harbour lower butterfly densities in comparison to control sites but undiminished numbers of species. Species composition varied significantly between control sites and islands and amongst control sites, near islands and far islands. Interspecific differences were observed in species' responses to fragmentation. Charaxines, medium-sized satyrines, morphines and brassolines may be vulnerable to extinction after habitat fragmentation while small-sized satyrines may be relatively resistant. Observations during the dry season indicate that butterfly species may exist as mainland-island metapopulations in Lago Guri, in which small habitat fragments require recolonization every year from source populations in large islands and mainland habitat.

Horaga onyx (Moore 1857) commonly known as Common Onyx or Blue Onyx is one of the rarest Lycaenid butterfly species found in Sri Lanka.  Only a handful of sight records are there of this butterfly and much of the biology of this butterfly in Sri Lanka has not been studied. Here we report the first record of this species ovipositing in Sri Lanka and first record of its host plant, Macaranga indica.

The butterfly surveys were conducted across different regions of Jammu province right from southern alluvial plains of Chenab and Ravi to Great Himalayas through Shiwaliks and Pir-Panjal mountains during June 2016 to February 2018. The areas covered included  Kalidhar and Dalhori  forests, district Rajouri (west), Mansar-Surinsar-Manwal range, districts Jammu, Samba and Udhampur (south), Mansar-Manwal, Billawar-Basoholi-Bani, district Kathua (east), Bhaderwah, district Doda (north), and Paddar in district Kishtwar (northeast) within an elevational range of 320 m to 3200 m (Fig. 1). During the explorations, we observed eight Lycaenid butterfly species previously not recorded from the state of Jammu and Kashmir.

Wing Scales

We studied the structural as well as spatial and spectral reflectance characteristics of the wing scales of lycaenid butterfly species, where the scale bodies consist of perforated multilayers. The extent of the spatial scattering profiles was measured with a newly built scatterometer. The width of the reflectance spectra, measured with a microspectrophotometer, decreased with the degree of perforation, in agreement with the calculations based on multilayer theory.

Trait Associations

Background. Adaptation to local habitat conditions may lead to the natural divergence of populations in life-history traits such as body size, time of reproduction, mate signaling or dispersal capacity. Given enough time and strong enough selection pressures, populations may experience local genetic differentiation. The genetic basis of many life-history traits, and their evolution according to different environmental conditions remain however poorly understood. Methods. We conducted an association study on the Glanville fritillary butterfly, using material from five populations along a latitudinal gradient within the Baltic Sea region, which show different degrees of habitat fragmentation. We investigated variation in ten principal components, cofounding in total 21 life-history traits, according to two environmental types, and 33 genetic SNP markers from 15 candidate genes. Results. We found that nine SNPs from five genes showed strong trend for trait associations (p-values under 0.001 before correction). These associations, yet non-significant after multiple test corrections, with a total number of 1086 tests, were consistent across the study populations. Additionally, these nine genes also showed an allele frequency difference between the populations from the northern fragmented versus the southern continuous landscape. Discussion. Our study provides further support for previously described trait associations within the Glanville fritillary butterfly species across different spatial scales. Although our results alone are inconclusive, they are concordant with previous studies that identified these associations to be related to climatic changes or habitat fragmentation within the Åland population.

AbstractMany studies in population ecology have shown that related species have different dispersal behaviours. Species with sedentary and migratory behaviour exist in butterflies. While the genetic responses to population isolation are well studied, the effects of different dispersal behaviours of species are widely unknown. Therefore, we analysed 19 allozyme loci of two lycaenid butterflies,Cupido minimusas a sedentary butterfly andAricia agestisas a mobile and expansive species. We collected 594 individuals (280 ofC. minimusand 314 ofA. agestis) in a western German study region with adjacent areas in Luxembourg and northeastern France. The genetic differentiation among populations ofA. agestis(FST=3.9%) was lower than inC. minimus(FST=5.6%). Both species built up an isolation-by-distance system, which is more pronounced inA. agestisthan inC. minimus. The genetic diversity inC. minumuspopulations (e.g.Ptot=73.5%) is higher for all analysed parameters than inA. agestis(e.g.Ptot=52.1%). Both species show specific genetic characteristics fitting with their different dispersal behaviours and respective ecological strategies. In the light of conservation genetics, we deduce that highly fragmented populations do not necessarily have a high extinction probability, but this risk depending much more on specific population genetic structures. In the studied species,C. minimuspreserves a complex genetic constitution by high population densities. The patchily distributedA. agestisrepresents less rare alleles, present only in some populations, and holds up genetic diversity by high mobility.

Abstract Habitat fragmentation and the creation of so-called edge effects may have different implications on flora and fauna, including complex genetic responses. This study aimed to analyze the genetic diversity in a local population of the shade tolerant tree Trichilia elegans A. Juss (Meliaceae), with emphasis to the evaluation of genetic variation towards an edge-interior gradient. The results of isoenzymes assays showed that the edge subpopulation experienced the highest allele loss, while fixed alleles increased towards the interior. The total polymorphic loci percentage was 76.67%, being higher in the Middle subpopulation, whilethe average sample size for a locus (N) and the mean number of alleles for a locus (Na) were significantly lower in the Edge subpopulation. The indices Ho, He and f showed good heterozygosity in the total population, indicating high genetic variability. The genetic distance Fst and Nm followed the same pattern, with Middle and Interior subpopulations showing higher similarity and the Edge as the farthest one, also showing less gene flow in relation to the others. Principal Coordinates Analysis (PCoA) allowed us to separate the three subpopulations with the first two axes explaining 65% of total variation, confirming that forest fragmentation affects the genetics of Trichilia elegans within the analyzed fragment.

The family Lycaenidae is the second-largest group of butterflies which contains about one third of the known species of Papilionoidea. The genera Tajuria Moore, [1881] and Drupadia Moore, 1884 are both mainly found in the Oriental and Australian realms. In a very recent expedition to south-west China in Xishuangbanna (Yunnan Province), specimens of T. sekii Saito, 2005 and D. scaeva (Hewitson, 1869) were collected for the first time, a new subspecies of the former: T. sekii sisyphus ssp. nov., is described and illustrated and the latter species comprises the first record of the genus Drupadia in China. A new subspecies of T. sekii Saito, 2005, T. sekii sisyphus ssp. nov., is described and illustrated. The species T. sekii Saito, 2005 and D. scaeva (Hewitson, 1869) are first recorded in China and the latter comprises the first record of the genus Drupadia in China. Relevant details are presented for the species.
