Records of brown widow spider, &lt;I&gt;Latrodectus geometricus&lt;/I&gt; Koch 1841, (Araneae: Theridiidae) from Gujarat, western India, with notes on its distribution, habitat and natural history

Specimens of Latrodectus hasseltii were collected from Gujarat State, Western India during 1970 to July 2015. All the records of its occurrence were placed together to establish its wide spread distribution and habitat association. It showed higher association with forest (36.6%) and wasteland (33.3%) habitats compared to agricultural (23.3%) and human residential (6.6%) habitats. L. hasseltii has been recorded from 11 forest areas, out of 13 forest areas surveyed intensively in Gujarat State. Out of nine crops studied in Gujarat state, L. hasseltii was recorded only from three crops (castor, cotton and lucerne).

The challenge of compassion in predator conservation

This paper argues that compassion for wild animals and the humans living alongside them should be integral to wildlife conservation. Nowhere is this more apparent than in predator conservation, and case studies are used to explore the consequences of wild animal attacks for human victims. Some arguments for extending compassionate consideration to animals seen as individuals are considered, along with the challenges these pose for predator conservation. A way forward from this apparent impasse is suggested, drawing on the capacity approach to embrace human with animal actors. The paper concludes with implications for predator conservation and recommendations, including incident responses sensitive to the traumatic impacts of attacks, and more collaborative approaches to handling human-wildlife interactions taking account of the capacities of local humans and wildlife.

“…They are occasionally found on more natural substrate, such as vegetation, but in the majority of these cases the vegetation is a microhabitat associated with urban environments (Brown et al 2008; Vetter et al 2012b). They are generalist predators and consume a wide variety of insects, arachnids, and occasionally much larger prey such as reptiles, amphibians, and small mammals (Lira & Costa 2014; Taucare-Ríos & Canals 2015; Vasava et al 2015; Rocha et al 2017; Luna et al 2020). The venom of brown widow spiders is more toxic in mice, compared to the venom of most congeners, but on average they deliver a smaller amount of venom in their bite, posing a lower risk for human health (McCrone 1964).…”

Introductions of non-native species to novel environments happen often, but a species must overcome multiple biotic and abiotic filters to establish and eventually spread. Focusing on patterns of introductions can provide insights as to underlying mechanisms that facilitate establishment, and in turn, their potential effects on native communities. The brown widow spider, Latrodectus geometricus C. L. Koch, 1841, is likely native to Africa, but now has a cosmopolitan distribution due to introductions via international trade. We reviewed the patterns of brown widow introductions in the Americas to determine if there are any large-scale inferences regarding their patterns, and potential impacts, of their introduction. A total of 5,004 records from 30 countries were synthesized and demonstrate their spread to higher latitudes across time with the majority of those records (n ¼ 4,923; 98%) occurring in the past two decades. Brown widows are now documented in 30 of the 35 countries in North, Central, and South America, with one-third of those introductions detected in the last 30 years. Citizen-science databases (e.g., iNaturalist) have been instrumental in documenting the expansion of the brown widow, as more than 90% of the records synthesized came from these sources. Brown widows have proven to be successful invaders worldwide, and this review synthesizes expansion reports of their invasion in the Americas in hopes of spurring additional research in locations where they have become established.
