Abstract Background It has been recognized that a certain amount of habitat disturbance is facilitating factor for the occurrence natural hybridization, yet to date we are unaware any studies exploring hybridization and reproductive barriers in those plants preferentially occupying disturbed habitats. Buddleja (also called butterfly bush) generally do grow habitats, several species with hybrid ...

The estimation of the modern state arboreal plants dendropark Lugansk State Agrarian University was first given. It set that now 5712 copies trees, bushes and lianas, related to 104 species from 63 genus 29 families, sprout on this territory. Dominant position is occupied by trees - 55.6%, 37.0% lianas 7.4%. conditions Aesculus hippocastanum L., Betula pendula Roth, Populus alba L. nigra are ca...

Specialty forages are those that do not have a wide application in animal production systems of Texas. Other than beef cattle, systems that use cultivated forage can be considered atypical in our state. These include white-tailed deer, game birds (quail or turkey), exotic game, goats, sheep, domesticated rabbits or any other species that is primarily an herbivore. These animals generally requir...

The influence of low vegetation on laser scanning and its disturbing effect (a systematic positive height shift) during DTM generation is well recognized. Based on our experience in a previous study of estimating the effect of medium-height vegetation (shrubs and bushes) in rough terrain by using point-cloud based co-occurrence texture methods, we now investigate the effect of lower vegetation,...

This study reviews forensic entomological specimens analysed by the Department of Parasitology & Medical Entomology, Universiti Kebangsaan Malaysia for the year 2004. A total of 10 cases (6 males and 4 females) were observed for the entomological specimens. Various types of death scenes were obtained including indoor and outdoor area such as bushes field, rubbish dumping site, and aquatic areas...

Empirical demonstrations of feedbacks between ecology and evolution are rare. Here, we used a field experiment to test the hypothesis that avian predators impose density-dependent selection (DDS) on Timema cristinae stick insects. We transplanted wild-caught T. cristinae to wild bushes at 50 : 50 cryptic : conspicuous morph ratio and manipulated density by transplanting either 24 or 48 individu...

HE white pine weevil (Pissodes strobi (Peck)) is one of the most destructive forest insect pests in the Northeast. By causing forked and crooked boles, extreme limbihess, and weaknesses in the wood itself, it has greatly reduced the usefulness and value of the injured white pine for all the more exacting needs of the lumbe• and building trades. This has been one .of the principal factors respon...

Habitat modification is a major factor in the decline of reptile populations. The degree has been shown to be directly related intensity habitat modification. Farming practices and urbanization are just two factors involved indicating that development minimize or cancel anthropogenic impacts urgently needed prevent further declines. This requires knowledge population ecology reptiles both distu...
