“…The later species is regarded as one of the 100 worst alien species in Europe (Brochier et al, 2010) and may in future expand throughout the Bangkok region threatening native cavity nesting species as is thought to be the case elsewhere in the Rose‐ringed Parakeet's non‐native range (Strubbe & Matthysen, 2009). Finally, and despite the low number of non‐native species, we found that the richness of non‐native species increased along the urbanization intensity gradient, contrasting with declines in species richness for all other groups, therefore providing support for conclusions that urban areas favor non‐native species (Lazarina et al, 2020; Tomasevic & Marzluff, 2017).…”

“…Urban assemblages, including avian ones, are often considered to include a high proportion of established non‐native species (Lazarina et al, 2020; Marzluff, 2001). Yet, only a small proportion of species detected in our surveys (five of the 142 recorded species, 3.5%) were non‐native to the Bangkok region and, of these, only two species were widespread (Rock Pigeon Columba livia and Zebra Dove Geopelia striata ).…”

Urbanization is a major driver of tropical biodiversity loss. In temperate regions avian species richness-urbanization intensity relationships typically exhibit unimodal patterns, with peak richness at intermediate urbanization levels. In tropical regions, the form of such relationships and the extent to which they are moderated by patches of seminatural habitat are unclear. We address these questions in Bangkok, Thailand (one of the largest and most rapidly expanding tropical mega-cities) and generate conservation recommendations for tropical biodiversity in urban locations. We use repeated point count surveys at a random location, and the largest available woodland patch, in 150 1 km Â 1 km grid cells selected along the urbanization gradient. Woodland patches support higher species richness compared with randomized locations (except for non-natives), and avian species richness declines linearly with increasing urbanization. The contrast with unimodal patterns in temperate regions is probably driven by divergent patterns of habitat heterogeneity along tropical and temperate urbanization gradients. Moreover, we provide novel evidence that retaining patches of urban woodland moderates adverse impacts of urbanization on avian species richness. For most species groups, the benefits of woodland increase as urbanization intensifies, despite such woodland patches being very small (mean of 0.38 ha). Avian species richness in woodland patches is maximized, and community composition less similar to that in randomized locations, when woodland patches are larger and visited by fewer people. Assemblages of forest-dependent species (which provide additional ecological functions) have higher richness, and are less similar to those in randomized locations, in patches of woodland with higher tree species richness and biomass. Finally, species richness in randomized sites is greatest when they are closer to woodland patches, and such assemblages more closely resemble those of woodland sites. Our work highlights four strategies for tropical urban bird conservation: (1) conserving woodland patches across the urbanization gradient regardless of patch size, (2) improving the quality of existing woodland by increasing tree biomass and diversity, (3) creating additional woodland that is well distributed throughout the urban area to

“…On the other hand, alien species feel more comfortable in highly populated areas where the ecosystem functionality is adulterated, and they can exploit many gaps efficiently to find food and nesting resources [8][9][10]. In areas where the ecosystem structure is weaker, they can more easily find a suitable niche.…”

Climatic Niche of an Invasive Mantid Species in Europe: Predicted New Areas for Species Expansion

2023

While some species naturally expand their range by finding suitable climatic and trophic niches in new areas, others have been transported intentionally or unintentionally by humans since their journey from Africa to other continents. This phenomenon has occurred throughout history, being more prevalent at the end of the Middle Ages and at the start of the Industrial Revolution, with its frequency increasing in recent times due to globalization. Hierodula tenuidentata Saussure, 1869 is a mantis species originally distributed from India to Caucasus, that started to become more and more common in many European countries in the last few years, being considered an alien species. However, there is limited information available regarding its distribution range, habitat preference, and other ecological requirements that can help us understand its movements. We used observation data from its range, along with bioclimatic and elevation variables, to build Species Distribution Models in MaxEnt. This allowed us to analyze the species’ spatial ranges and understand and predict its distribution across Europe. Before selecting the best-fitting models, the occurrence data were spatially filtered, and bioclimatic variables tested for multicollinearity. Based on the present species distribution models, with AUC values of 0.967 for the training data and 0.960 for the test data, Hierodula tenuidentata emphasizes a coastal occurrence in the Black Sea and Mediterranean Sea regions, with local observations in southeastern Europe, an area that is likely to be occupied in the next few years through species expansion. Our data show that the expansion of Hierodula tenuidentata in Europe is influenced by the natural movement of the species westward combined with human introduction in some areas. It is now evident that the species’ presence in Europe is not solely based on human-aided dispersion, as was previously believed. The main variables influencing the distribution of Hierodula tenuidentata across Eurasia are temperature and precipitation, both of which have been significantly modified in recent years due to climate change.

“…Many studies of the effects of urbanization on avian wildlife compare populations along an urban to rural gradient, but our ndings contribute to a growing body of evidence that suggest that rural land use changes may affect species alongside urbanization (e.g. Kumar and Kaur Kler 2021, Lazarina et al 2020).…”

Urbanization has altered organisms and ecosystems around the world and will continue to do so into the foreseeable future. Although avian responses to urbanization at the community level have been well characterized, we lack species-level studies examining differences in spatial distributions in response to urbanization. We tested for differences in spatial distributions of two congeneric passerine bird species across an urban ecosystem: northern cardinals (Cardinalis cardinalis) and pyrrhuloxia (Cardinalis sinuatus), two closely related songbird species that overlap in distribution. We developed and deployed a new method for testing differences in spatial distributions between species using MaxENT, eBird, and structured bird-survey data across two regions: the state of Arizona and across the Tucson metropolitan area. We then investigated potential urban-environmental factors that may similarly or differentially influence spatial distribution of (a) northern cardinal populations in two urban centers in the state (Tucson and Phoenix) and (b) both species in and around Tucson. We found that northern cardinals occur both further north in the state of Arizona and further into the city of Tucson than pyrrhuloxia. We also found that pyrrhuloxia are excluded from urban areas by habitat availability, but that they are positively associated with human development. High-intensity urbanization has limited urban northern cardinal distributions, and their affinity for areas near open water may have facilitated their northward expansion across the state. We show that species distributions in response to habitat urbanization differ between even closely related species with very similar niches, and characterize environmental associations that drive these differences.
