“…In common across studied Amblypygi is the occupation and defense of small areas around a single refuge. Refuges typically follow a shape suitable to accommodate the dorso-ventrally flattened amblypygid body form such as in cracks and crevices in cave walls (Chapin 2015) or in tropical tree buttresses (Hebets 2002;Dias & Machado 2006;Carvalho et al 2012;Chapin 2014), under debris like rocks and logs (Fowler-Finn & Hebets 2006), in appropriated abandoned burrows (Weygoldt 2000), in bracts of bromeliads (Jocque & Giupponi 2012), or even in termite mounds (Carvalho et al 2011). Refuges house individuals during daylight hours and provide shelter from predators.…”

“…Contests within select amblypygid species are well-described (Weygoldt 1969(Weygoldt , 1974a(Weygoldt , b, 1977a(Weygoldt , b, 2000Fowler-Finn & Hebets 2006;Santer & Hebets 2008;Chapin 2015). Interactions appear quite ritualized and stereotyped as they frequently follow a regular sequence of behaviors supposedly adapted for communication (e.g., Santer & Hebets 2008).…”

“…For example, when presented with an opponent, individuals generally engage in a series of pedipalp and antenniform leg movements that may escalate to physical aggression in a regular sequence (Santer & Hebets 2008). Injuries during contests range from nonexistent (Weygolt 1977a;Fowler-Finn & Hebets 2006;Santer & Hebets 2008) to frequent death and cannibalism (Chapin 2015). While specifics of agonistic interactions vary across species, most species studied to date include vibrations and fencing with antenniform legs in addition to pedipalp movements in …”

“…Laboratory trials show that size, body condition, antenniform leg movement, and body raising predict RHP and contest outcome (Fowler-Finn & Hebets 2006;Santer & Hebets 2008;Chapin & Hill-Lindsay 2015). Further, males of many species have elongated pedipalps as compared to females (Weygoldt 2000;Chapin 2011Chapin , 2014, which might play a role in territory contests.…”

“…Nearly all studies of intraspecific encounters have focused on antagonistic interactions between males; however, female-female contests are also observed in some taxa, for example in cichlids (Draud et al, 2004), whip spiders (Weygoldt, 1969(Weygoldt, , 2000Fowler-Finn and Hebets, 2006), pied flycatchers (Dale and Slagsvold, 1995), and spiders (Nossek and Rovner, 1984;Hodge, 1987;Jackson and Whitehouse, 1989;Fernández-Montraveta and Ortega, 1990). Because males and females adopt different strategies to maximize reproductive success, selection has acted differentially on the sexes to result in different agonistic behaviors between males and females (Draud et al, 2004;Fowler-Finn and Hebets, 2006).…”

AimThe biogeography of terrestrial organisms across the Florida Keys archipelago is poorly understood. We used population genetics and spatioecological modeling of the Amblypygi Phrynus marginemaculatus to understand the genetic structure and metapopulation dynamics of Keys populations that are otherwise isolated by human development and ocean.LocationThe Florida Keys archipelago and mainland Florida.MethodsWe sequenced a 1,238 bp fragment of mtDNA for 103 individuals of P. marginemaculatus from 13 sites in the Florida Keys and South Florida, binned into four regions. We used population genetic analyses to understand the population structure of the species throughout its US range. Furthermore, we used ecological modeling with climate, habitat, and human development data to develop habitat suitability estimates for the species.ResultsWe found clear genetic structure between localities. The Lower Keys, in particular, support populations separate from those in other regions studied. Ecological modeling and genetic analyses showed the highest habitat suitability and genetic isolation in the Lower Keys, but urban development across the species range has resulted in the loss of most historical habitat.Main conclusionsA mainland‐metapopulation model best fits P. marginemaculatus gene flow patterns in the Florida Keys and mainland. Ocean currents likely play a role in metapopulation dynamics and gene flow for terrestrial Keys species like P. marginemaculatus, and genetic patterns also matched patterns consistent with geologic history. Suitable habitat, however, is limited and under threat of human destruction. The few remaining pockets of the most suitable habitat tend to occur in parks and protected areas. We argue that conservation efforts for this species and others in the terrestrial Florida Keys would benefit from a deeper understanding of the population genetic structure and ecology of the archipelago.
