The vegetational landscape of north-easternTerairegion at the foot hills of Central Himalayas is a mosaic of grassland, old-field, wasteland, and forest ecosystems. Like many other parts of the country, this region is also infested with alien intruders which not only interfere with the growth and production of food crops but also exercise adverse effects on the biodiversity of native species. The present study attempts to catalogue the invasive alien species of the terrestrial vegetation of north-eastern Uttar Pradesh especially with reference to their habit, taxonomic position, and nativity. A total of 1135 plant species within 580 genera under 119 families are so far known to occur in the region. Of these, only 149 species within 100 genera under 41 families have been found to be invasive aliens as evident from their center of origin, past history, nature of aggregation, and invasion observed under field conditions. About 80% of these invaders have been introduced from neotropics. Out of 173 invasive plants across India, this region shares 149 species, out of which 66% of species have come from Tropical America, 14% from African continent, and the rest from other countries. A better planning in the form of early identification and reporting of infestation and spread of noxious weeds is needed for their control.

Vindhyam range of Uttar Pradesh, India comprises 149 alien species under 106 genera belonging to 44 families. On analysing the data it was observed that 73% of alien species are from tropical America including South America and 10.5% from tropical Africa. Present study is based on several years of intensive exploration of the area. Excursions were under taken in different areas at regular intervals. During excursions information regarding important alien species with their legitimate botanical name, families, local name brief description along with flowering and fruiting time were recorded.

AbstractThis summary provides an overview of the golden jackal (Canis aureus) categorization in Europe with particular focus on its presence in Slovakia. The distribution range of this species in Europe has been expanding in recent decades. Currently, European population is in constant and fast increase, widening their ranges towards Central and Eastern Europe and more recently in some western countries. All over Europe, the categorization of the golden jackal status is discussed with some controversial. A recent genetic study helped to determine that golden jackals do not meet the established three criteria, which categorize a species as an invasive alien species. In Slovakia, golden jackals’ numbers grown considerably in the last decade and with an increasing of their distribution through the country it became a permanent species of the Slovak fauna. The only internal status is the hunting Act no. 274/2009, which classifies it as, game species. The fast adaptation and dispersion through Slovakia can be considered similar to the behaviour of an invasive species, as suggested in previous studies in Hungary. Based on widely accepted definitions, agreed under international legal instruments, it is quite clear that the term ‘Invasive Alien Species’ only encompasses non-native species specifically introduced by humans (intentionally or accidentally). Following this Invasive Alien Species terminology, golden jackals cannot be categorized as such in Slovakia. The natural expansion, the growing ranges, and the increase in numbers of the golden jackal in Slovakia in the last decades points to a need to improve the knowledge of the species.

The composition and diversity of climbers among grassland, wasteland and forest vegetations was examined with respect to their woodiness, climbing mode and circumnutation pattern across the vegetational landscape of north-eastern Uttar Pradesh during 2011-2015. A total of 111 climbers, constituting 63 lianas and 48 vine species, under 35 families, were recorded. The forest and wasteland vegetation were quite similar in regard with climber diversity. Family Convolvulaceae included a maximum of 19 climbers. Majority of twining climbers showed right-handed twining.  The wasteland vegetation was most suitable and quite similar to forest habitat for vines as well as for lianas. The right handed circumnutation was the dominant pattern among the twiners of the region. Local climbing flora provides considerable natural resource to the region. They often create special micro-habitats and increase the complexity of the ecosystem.

The deliberate or accidental introduction of invasive alien species (IAS) causes negative ecological and economic impacts altering ecosystem processes, imperiling native species and causing damage to human endeavors. A monthly monitoring program was performed in Lake Trasimeno (Central Italy) from July 2018 to July 2019 in order to provide an upgrade of the population ecology of Procambarus clarkii and to assess the genetic diversity by analyzing the relationships among mitochondrial DNA diversity. Our results confirmed that P. clarkii is well acclimatized in the lake, revealing a stable population structure favored by the resources and conditions typical of this ecosystem, which seem to be optimal for the maintenance of the species. Four distinct mitochondrial haplotypes were detected, but one of them was clearly overrepresented (76%), suggesting that a single predominant introduction event may have occurred in this area, likely followed by secondary events. The identification of the typical genetic variants provides a better understanding of the evolutionary scenarios of P. clarkii in this biotope and it can be helpful in management plans concerning the expanding populations of this invasive alien species.

The present study aims to compare the composition, diversity and distribution pattern of legumes vs. non- legumes in the regional sal forest of north- eastern Uttar Pradesh, India. In order to show pattern of change in different phytosociological data, the species of similar habits were sorted into different habit groups. In addition to usual regeneration through seeds, a number of legumes also showed non- seed regeneration strategy. As many as 57% of the total legume individuals were of ramet origin but belonged only to 5% of the legumes of forest. The presence of legumes with 41 species (out of 246 in regional forest) sharing 17.7% of importance value (IVI) in sal forest was noticeable. About one third total individuals in forest were herbaceous. Mean density for legume trees was >6 per ha while it was > 6000 per ha for legume shrubs. Moghania chappar, M. lineata, M. bracteata and Desmodium gangeticum were most abundant legume shrubs in regional sal forest. The general rank- abundance curve for regional sal forests was quite steep and close to log normal curve. The legume diversity is crucial for nutritional status of forest soil and legumes are known to heal the disturbed forest. Besides information on the present status of common leguminous vs. non- leguminous species, the results provide clues for the management option in these forests and for the maintenance of legume diversity in such stochastic environment.
