Can Deliberately Incomplete Gene Sample Augmentation Improve a Phylogeny Estimate for the Advanced Moths and Butterflies (Hexapoda: Lepidoptera)?
2011
Abstract This paper addresses the question of whether one can economically improve the robustness of a molecular phylogeny estimate by increasing gene sampling in only a subset of taxa, without having the analysis invalidated by artifacts arising from large blocks of missing data. Our case study stems from an ongoing effort to resolve poorly understood deeper relationships in the large clade Ditrysia ( > 150,000 species) of the insect order Lepidoptera (butterflies and moths). Seeking to remedy the overall weak support for deeper divergences in an initial study based on five nuclear genes (6.6 kb) in 123 exemplars, we nearly tripled the total gene sample (to 26 genes, 18.4 kb) but only in a…
Information on the macrolepidoptera fauna of “Dumbrava Sibiului” oak forest (Sibiu, Romania)
2015
In order to establish systematic, ecological and ethological studies, it is extremely important to know the composition of faunal species of Lepidoptera collected in the past and present from "Dumbrava Sibiului" Forest located on the outskirts of Sibiu in central Romania. To assess the current state of Lepidoptera species, we conducted a complex research which was carried out for over 13 years, based on our own samples collected: from March to November, but also on the data resulted from studying the species existing in the collections of the Natural History Museum of Sibiu. After the research we have identified a number of 243 species belonging to 14 families collected over time from "Dumb…
Macrolepidoptera (Insecta: Lepidoptera) Indicator of Climate Changes
2011
Lately, it has become increasingly clear that global warming has a significant impact on a broad range of organisms, regardless of their ecological and geographical spread. Temperature is one of the most important abiotic factors that determine the spatiotemporal dynamics of structural and functional parameters of populations of Lepidoptera and influencing production and survival of these species of insects in nature. Climate warming has the potential to affect some processes related to the ecology and life cycle of the butterfly, especially directly controlled temperature, such as: gathering the required temperature for a species to reach reproductive maturity, growth initiation and cessat…
MANAGEMENT ECOSYSTEM IN DUMBRAVA SIBIULUI FOREST ON THE EVOLUTION OF SPECIES MACROLEPIDOPTERA SIBIU DURING THE YEARS 2000-2012
2014
It was studied the ecology and phenology, the flight periods of the Macrolepidoptera during the period 2000-20012 in the Natural Park „Dumbrava Sibiului”. The natural conditions and the specific features were mentioned in my previous papers (Stancă-Moise, 2000, 2002, 2003, 2004, 2007, 2010, 2011, 2012). There is no doubt that the appearance of the different species of Macrolepidoptera in different periods of time is in a direct relation with the succession of the climatic conditions. The flight periods express the biological specific feature of each species of Lepidoptera, being in direct connection with the activity of feeding and reproduction of imagos.
MACROLEPIDOPTERA SPECIES WITH VULNERABLE STATUS AND THEIR IMPACT ON THE PROTECTED AREA OF DUMBRAVA SIBIULUI
2013
The present work is a part of a complet study concerning of Macrolepidoptera from the forest “Dumbrava Sibiului” in the Sibiu county. They are presented only the species found by myself for the frist time from this area. I mention that these species were not found by me in the five collections of Lepidoptetra studied by me and preserved at the Natural Hystory Museum in Sibiu.
