Abstract:

Determining whether the climatic ecological niche of an invasive alien plant is similar to that of the niche occupied by its native population (ecological niche conservatism) is essential for predicting the plant invasion process. Ragweed (Ambrosia artemisiifolia L.) usually poses serious threats to human health, agriculture, and ecosystems within its newly occupied range. We calculated the overlap, stability, unfilling, and expansion of ragweed’s climatic ecological niche using principal component analysis and performed ecological niche hypothesis testing. The current and potential distributi

Abstract:

Artibeus aztecus is a Mesoamerican montane bat with three currently recognized, allopatric subspecies. No study has evaluated the phylogenetic status of the subspecies. However, through an analysis of its ecological niche and its geographic distribution, here we analyze whether there is differentiation of the climatic requirements for each subspecies, assessing whether niche evolution is a potential factor in subspecies differentiation. We assayed ecological niche models for each subspecies, analyzed the response curves for the most important climatic variables of each model, and generated the

Abstract:

The ecological niche of Vallonia pulchella (Muller, 1774) was investigated by means of the general factor analysis of GNESFA. It was revealed that the ecological niche of a micromollusk is determined by both edaphic factors and ecological features of vegetation. Ecological niche optima may be presented by integral variables such as marginality and specialization axes and may be plotted in geographic space. The spatial distribution of the Vallonia pulchella habitat suitability index (HSI) within the Technosols (sod-lithogenic soils on red-brown clays) is shown, which allows predicting the optim

To determine whether behavioural plasticity in foraging modes is contingent upon the morphology of the species, we analyzed the variability in frequency of use of foraging postures (standing versus hanging) under the selection pressure of predation risk.

Results demonstrated that the leg morphology of the Blue Tit provides it with greater ecological plasticity in terms of foraging posture than that of the Crested Tit.

The territory of the Crimean Peninsula has a long history of economic development and as a result, in some, especially old-developed, regions of the Crimean Peninsula, there is a problem of the use of the territory by various nature users and, consequently, nature management conflicts are developing.

Abstract:

Due to the pet and goods trade, several animals are now present in regions outside of their traditional native ranges. A peculiar situation has arisen in mantises, insects that are becoming more popular as pets: two genera (<i>Hierodula</i> and <i>Tenodera</i>) have begun to spread around the world, with two <i>Hierodula</i> species overlapping in Europe and two <i>Tenodera</i> species doing the same in North America. Such an event can lead to possible competition with both local taxa and alien congeneric sister species; the latter may reduce the impact of one of the invaders. Additionally, th

Abstract:

Pathogens of the Burkholderia genus are causing diseases in a diverse variety of hosts. After the discovery of T6SS, it was found to play a pivotal role in virulence and other pathogenicity factors in different pathogenic Burkholderia species. For this study, three strains of Burkholderia cenocepacia were selected from different ecological niches; J2315 from humans, MC0-3 from the rhizosphere of maize, and YG-3 from the Populus tree. The sequenced genomes were retrieved from PATRIC. It was found that B. cenocepacia J2315 and MC0-3 strains had only 1 cluster of T6SS in their genomes while the Y

Abstract:

The spatial niche has garnered significant attention in ecological research, particularly regarding species distribution patterns. The East China Sea, known for its favorable natural conditions and abundant fishery resources, exhibits diverse spatial distribution patterns among species, shaped by their seasonal physiological needs. This study utilized a habitat suitability index model to explore the spatial distribution patterns of key fishery resources in the East China Sea across four seasons and their interactions. Two methodologies were employed to identify key environmental factors and as

There were 4 used datasets: existing planted vetiver data, 3 topographical data (DEM, slope, and aspect), bioclimatic data, and the modified soil data. These datasets were transformed into GIS data with WGS 1984 and Zone 48N and were processed by ecological niche factor analysis (ENFA) in BIOMAPPER.

Trapping the Asian hornet remains a viable alternative to monitor its presence, dispersion, and ecological niche. With the objective of evaluating the effectiveness of baits and traps, an Asian hornet (Vespa velutina) capture trial was conducted using combinations of artisanal and commercial baits and traps. The second objective was to explore the relationship between the species’ dispersal patterns and the influence of human, geography, climate, and vegetation factors, to identify the preferred conditions for its colonization. We identified beekeepers in the Alto Minho region of Northern Port

During this study, the habitat suitability of Ground squirrels has been investigated based on species data and various habitat data such as topographic variables, distal variables, and bioclimatic factors. Two model evaluation indices, including Boyce and Idrisi tests, indicated the models’ performances. Based on findings, mean annual precipitation and landuse as well as slope direction showed to be the most important factors influencing the species’ habitat use.

Heptacodium miconioides is listed by the International Union for Conservation of Nature (IUCN) as a rare and endangered plant which is being subjected to competition for environmental resources by Fraxinus insularis. The impact of competing species on the dispersal of H. miconioides across time and space is unclear, which hinders our ability to effectively protect rare and endangered species. Therefore, in this study, we performed a spatial analysis of the interactions between H. miconioides and F. insularis using the Maximum Entropy model (MaxEnt) coupled with the Spatio-temporal Geographic W
