Orb Weavers, Neoscona Crucifera (Lucas 1839) and Neoscona Domiciliorun (Hentz) (Arachnidae: Araneae: Araneidae)1 G
EENY316 Orb Weavers, Neoscona crucifera (Lucas 1839) and Neoscona domiciliorun (Hentz) (Arachnidae: Araneae: Araneidae)1 G. B. Edwards2 Introduction Neoscona crucifera (Lucas 1839) and N. domiciliorum (Hentz 1847) are common and conspicuous members of the moist woodland communities in much of Florida. These spiders are beneficial, consuming a variety of insects. Although typically nocturnal throughout most of their life spans, adult females can be found sitting head down in the hubs of their webs during daylight hours of the fall season. Bites from these spiders are not known to cause serious effects to humans. Distribution These spiders have a wide geographic range: N. crucifera is found from Lake Okeechobee in southern Florida north to New England, west to Minnesota, and southwest to Arizona and central Mexico, whereas N. domiciliorum occurs southeast of a line drawn from Massachusetts to Indiana southwest to Texas. In the more northern states, males may mature as early as late June and females in July Figure 1. Dorsal view of female Neoscona crucifera (Lucas), an orb (Berman and Levi 1971), but in Florida, adults usually are weaver. not apparent until late August. Credits: G.B. Edwards, FDACS–DPI Systematics These two species have been confused with each other, mostly due to the interpretations by various authors of the descriptions by Walckenaer (1841) of two forms of Epeira 1.

Jump Takeoff in a Small Jumping Spider
Journal of Comparative Physiology A https://doi.org/10.1007/s00359-021-01473-7 ORIGINAL PAPER Jump takeof in a small jumping spider Erin E. Brandt1,2 · Yoshan Sasiharan2 · Damian O. Elias1 · Natasha Mhatre2 Received: 27 October 2020 / Revised: 4 February 2021 / Accepted: 23 February 2021 © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2021 Abstract Jumping in animals presents an interesting locomotory strategy as it requires the generation of large forces and accurate timing. Jumping in arachnids is further complicated by their semi-hydraulic locomotion system. Among arachnids, jumping spiders (Family Salticidae) are agile and dexterous jumpers. However, less is known about jumping in small salticid species. Here we used Habronattus conjunctus, a small jumping spider (body length ~ 4.5 mm) to examine its jumping performance and compare it to that of other jumping spiders and insects. We also explored how legs are used during the takeof phase of jumps. Jumps were staged between two raised platforms. We analyzed jumping videos with DeepLabCut to track 21 points on the cephalothorax, abdomen, and legs. By analyzing leg liftof and extension patterns, we found evidence that H. conjunc- tus primarily uses the third legs to power jumps. We also found that H. conjunctus jumps achieve lower takeof speeds and accelerations than most other jumping arthropods, including other jumping spiders. Habronattus conjunctus takeof time was similar to other jumping arthropods of the same body mass. We discuss the mechanical benefts and drawbacks of a semi- hydraulic system of locomotion and consider how small spiders may extract dexterous jumps from this locomotor system. -
Biodiversity and Community Structure of Spiders in Saran, Part of Indo-Gangetic Plain, India
Asian Journal of Conservation Biology, December 2015. Vol. 4 No. 2, pp. 121-129 AJCB: FP0062 ISSN 2278-7666 ©TCRP 2015 Biodiversity and Community structure of spiders in Saran, part of Indo-Gangetic Plain, India N Priyadarshini1*, R Kumari1, R N Pathak1, A K Pandey2 1Department of Zoology, D. A. V. College, J. P. University, Chhapra, India 2School of Environmental Studies, Jawaharlal Nehru University, New Delhi, India (Accepted November 21, 2015) ABSTRACT Present study was conducted to reveals the community structure and diversity of spider species in different habitat types (gardens, crop fields and houses) of Saran; a part of Indo – Gangetic Plain, India. This area has very rich diversity of flora and fauna due to its climatic conditions, high soil fer- tility and plenty of water availability. The spiders were sampled using two semi-quantitative methods and pitfall traps. A total of 1400 individual adult spiders belonging to 50 species, 29 genera and 15 families were recorded during 1st December 2013 to 28th February 2014. Spider species of houses were distinctive from other habitats it showed low spider species richness. The dominant spider fami- lies were also differs with habitat types. Araneidae, Pholcidae and Salticidae were the dominant spi- der families in gardens, houses and crop fields respectively. Comparison of beta diversity showed higher dissimilarity in spider communities of gardens and houses and higher similarity between spi- der communities of crop fields and gardens. We find that spiders are likely to be more abundant and species rich in gardens than in other habitat types. Habitat structural component had great impact on spider species richness and abundance in studied habitats. -

Ciudad Universitaria, Apartado postal 70-153, 04510 México, D. F., México. *Correspondencia: [email protected] Resumen. La ecología urbana es un área de investigación relativamente reciente. Los ecosistemas urbanos son aquellos defi nidos como ambientes dominados por el hombre. Con el proceso de urbanización, insectos y arácnidos silvestres aprovechan los nuevos microhábitats que las viviendas humanas ofrecen. Se revisaron arañas recolectadas dentro de 109 viviendas durante los años de 1985 a 1986, 1996 a 2001 y 2002 a 2003. Se cuantifi caron 1 196 organismos , los cuales se determinaron hasta especie. Se obtuvo una lista de 25 familias, 52 géneros y 63 especies de arañas sinantrópicas. Se utilizaron 3 índices (ocupación, densidad y estacionalidad) y un análisis de intervalos para sustentar la siguiente clasifi cación: accidentales (índice de densidad de 0-0.9), ocasionales (1-2.9), frecuentes (3.0-9.9) y comunes (10 en adelante). Se comparan las faunas de arañas sinantrópicas de 5 países del Nuevo Mundo. Palabras clave: sinantropismo, ecología, urbanización, microhábitats. Abstract. Urban ecology is a relatively new area of research, with urban ecosystems being defi ned as environments dominated by humans. Insects and arachnids are 2 groups that successfully exploit the habitats offered by human habitations. -
