Graph theoretic network approach has been used to model the potential connectivity of the natural areas in Darjeeling Himalayas which provide connectivity to the invasive species Maling bamboo (Yushania maling). Centrality indices are a tool for quantifying the intuitive notion of relative...

Humid highland forest enclaves are remnants of Atlantic Forest found in tablelands within the Caatinga biome (Northeastern Brazil), which emerged during interglacial periods in the Pleistocene. These ecosystems have a highly diverse and endemic fish fauna. Most earlier surveys have focused on the...

This study focuses on analyzing the behavior and seasonality in the canopy carbon exchange of a subtropical ecosystem at the Himalayan foothills and comprises three important invasive species: Lantana camara, Ageratum conyzoides and Bidens biternata. Systematic sampling on the daily CO₂ exchange...

Time of fruiting and their ripening plays an important role in attracting prospective dispersers in plant species. We have been monitoring a stand of Sapium sebiferum, an alien invasive species in order to document its phenology and seed dispersal patterns. Unlike majority of the plant species in...

This paper reports a new host association between Casimiroa pubescens and B. californicus in Tamaulipas state, northeastern Mexico. Populations of C. pubescens also known as "chapotillo" were observed in the semiarid highlands of Sierra Madre Oriental. A total of 67 leaves of this plant were...

The botanical composition of red and roe deer and mouflon diet was studied in the mosaic landscape in Drahanská vrchovina highlands, Czech Republic. We focused on the proportion and quality of agricultural crops and natural forest plants and estimated quality of the herbivore diet. Diet quality was ...

We examined trophic dynamics of a stream food web where invasive Orconectes neglectus appear to be displacing native O. eupunctus in the Spring River drainage of the Ozark Highlands, Missouri and Arkansas, USA. We collected crayfish species and possible food sources seasonally from a site of...

Habitat characteristics and the species attributes that determine the rate of spread of alien plant species are likely to be pivotal in determining the extent of homogenization, particularly at regional level. In order to determine which habitats are more likely to be homogenized and which groups...

In spite of the fact that introduced tree species represent an important forestry issue at both European and world levels, much less attention is paid to them in the Czech Republic. They are expected to have many functions, primarily the production of timber being superior compared to native...

The distribution and abundance of alien plant species can be strongly influenced by corridors that facilitate their dispersal. Although roads have been implicated as an important contributory factor in biological invasions, their precise role as conduits in the spatial spread of alien species...
