  ECOLOGICAL NICHE MODELS BY TITYUS SERRULATUS LUTZ & MELLO, 1922 AND TITYUS STIGMURUS (THORELL, 1876) (ARACHNIDA: SCORPIONES) Summary Scorpions are venomous animals with high plasticity and can serve as models for biogeographical, natural history, and evolutionary studies. Ecological niche modeling can help in understanding essential characteristics of the geographic distribution of species, as well as allowing the prediction of future distribution patterns. Our objective was to model the ecological niche of the scorpion species *Tityus serrulatus * and *Tityus stigmurus* , as well as to identify the variables that influence their distribution in different biomes and their range limits in the Amazon, Caatinga, and Cerrado biomes. Data were obtained from 12 Brazilian arachnological collections. Bioclimatic variables were obtained from the WorldClim database, and niche modeling was implemented using the Maximum Entropy algorithm. The results showed that the Atlantic Forest bio...

Spider Diversity (Arachnida: Araneae) in Suhelwa Wildlife Sanctuary’s Different Ecosystems, Terai Region, Uttar Pradesh, India

ABSTRACT

Spiders are essential parts of all ecosystems in which they exist, and they’re recognized to be good markers

of the diversity and health of terrestrial populations. However, the Suhelwa Wildlife Sanctuary’s spiders

are poorly documented, with hardly any information on their systematics, diversity, or ecology. The current

study aims to look into the spider faunal richness in a few habitats in the Suhelwa Wildlife Sanctuary in

Uttar Pradesh, India. The chosen environments yielded a total of 65 species, divided into 46 genera and 20

families. The maximum species richness was found at Razia Taal (Site C), while the lowest was found at

Hathiakunda Naala (Site D). The spiders were divided into seven functional categories based on their guild

structure: stalkers, orb-web builders, ambushers, space-web builders, ground runners, foliage runners,

and sheet-web builders. Finally, the highest species richness is linked to the flora and fauna of these locations.

The findings of this study provide useful and up-to-date information on the diversity of species found in

the Suhelwa Wildlife Sanctuary, and the data may be used for future spider research.
