Figure 1 in Field notes on the jumping spider Telamonia dimidiata in Maharashtra (Araneae: Salticidae: Plexippina)
Figure 1. Two female and one male Telamonia dimidiata in their nocturnal retreats at Nagaon Village. 1, Female resting between two crepe jasmine leaves. 2, Adult male in shelter beneath a crepe jasmine leaf. 3, Retreats were found in plants forming a double row of circular hedges surrounding a well. 4-8, Female in three different temporary retreats on three successive nights. The female rested under a silk platform constructed below a leaf of either twoleaf nightshade (4-5) or golden duranta (6-8). All retreats were constructed 1.3-2 metres above the ground. Photographs by Rajashree Khalap.

Figure 3. Encounter between an adult female Telamonia dimidiata and a salticid of the genus Rhene at Kalyan in the Thane District, Maharashtra, India (9 FEB 2019). 1, The Rhene was feeding on an Asemonea as it wandered on a branch occupied by the retreat of the Telamonia. 2, The Rhene approached the Telamonia. 3, The Telamonia left her retreat and faced the Rhene, at times with legs I extended. 4, The Rhene dropped the Asemonea and captured the Telamonia from the front. 5-12, Selected frames (5-8) with detailed views (9-12) of the Telamonia from a video of subsequent feeding by the Rhene. 9-12, Lines indicate axes of the AME of the Telamonia, which continued to actively scan as the Rhene fed.

University of Kansas Field Station: Cumulative field records of snake species collected by Dr. Henry S. Fitch 1948 - 2003, with a few additional records collected 2004 - 2016. Records contain capture locations, measurements, notes on reproduction, recapture, and growth data. This data package contains individual files for 14 species.
Dr. Henry S. Fitch began his pioneering research on the snake fauna of the Fitch Natural History Reservation and adjacent University of Kansas Field Station in 1948. Fitch remained an active researcher until the early 2000s. For nearly six decades he conducted extensive field work on snakes using capture/recapture techniques, and compiled other biological data as well (e.g., all snakes captured were weighed, measured, and marked with incomplete data collected on reproduction, stomach contents, and recaptures). This research resulted in scores of scientific publications on the ecology of the snakes. Henry S. Fitch died in 2009 and left as a legacy hand-written data sheets with approximately 60,000 capture records. George R. Pisani, a biologist at the University of Kansas and later at the Kansas Biological Survey, collaborated with Fitch on some ecological studies. Beginning about 2005, Pisani began the many-year process of converting the thousands of Fitch’s records of snake captures into an electronic database. This work was funded in part by the Kansas Dept. of Wildlife, Parks and Tourism Chickadee Checkoff Program.
Data from: Technical note: rapid image-based field methods improve the quantification of termite mound structures and greenhouse-gas fluxes
Termite mounds (TMs) mediate biogeochemical processes with global relevance, such as turnover of the important greenhouse gas methane (CH4). However, the complex internal and external morphology of TMs impede an accurate quantitative description. Here we present two novel field methods, photogrammetry (PG) and cross-section image analysis, to quantify TM external and internal mound structure of 29 TMs of three termite species. Photogrammetry was used to measure epigeal volume (VE), surface area (AE) and mound basal area (AB) by reconstructing 3D models from digital photographs, and compared against a water-displacement method and the conventional approach of approximating TMs by simple geometric shapes. To describe TM internal structure, we introduce TM macro- and micro-porosity (θM and θµ), the volume fractions of macroscopic chambers, and microscopic pores in the wall material, respectively. Macro-porosity was estimated using image analysis of single TM cross-sections, and compared against full x-ray tomography (CT) scans of 17 TMs. For these TMs we present complete pore fractions to assess species-specific differences in internal structure. The PG method yielded VE nearly identical to a water-displacement method, while approximation of TMs by simple geometric shapes led to errors of 4–200 %. Likewise, using PG substantially improved the accuracy of CH4 emission estimates by 10–50 %. Comprehensive CT scanning revealed that investigated TMs have species-specific ranges of θM and θµ, but similar total porosity. Image analysis of single TM cross-sections produced good estimates of θM for species with thick walls and evenly distributed chambers. The new image-based methods allow rapid and accurate quantitative characterisation of TMs to answer ecological, physiological and biogeochemical questions. The PG method should be applied when measuring greenhouse-gas emissions from TMs to avoid large errors from inadequate shape approximations.

FIG. 3. Cumulative rainfall for coastal southeast Texas. Note that the 2011 field season experienced only 54.8 in Nest Attendance Patterns in the American Alligator (Alligator mississippiensis)
FIG. 3. Cumulative rainfall for coastal southeast Texas. Note that the 2011 field season experienced only 54.8% of the normal rainfall through the first nine months of the year, while the 2012 season has much higher rainfall (71% above normal). This time frame covers the entire breeding, nesting, and incubation periods for alligators, and nest attendance patterns were not different between years despite drastic difference in climatic conditions.
