“…The shell size range, in which the infestation takes place, is a distinctive feature of the association between the 2 species, as the infestation of juvenile M. donacium depends on ontogenetic changes in shell morphology that increase the susceptibility to infestation (Riascos et al 2008). It is often difficult to assign taxonomic identity to species producing trace fossils, as evidence of life activities rather than soft tissues are being considered (Cameron 1969). However, the singularity of the described shell blistering, the similarity of the blister characteristics in fossil and recent shells and the fact that P. bioccipitalis is the only known polychaete associated with M. donacium (Blake 1983, Moreno et al 2006, Riascos et al 2008 strongly suggest that blisters in fossil shells were produced due to P. bioccipitalis infestations.…”

Polydora and related genera are common pests for molluscs. Establishing differences between native species and recent invaders provides the basis for understanding the effect of parasites and has implications for resource management. P. biocipitalis has been reported as a recently introduced species to the Chilean-Peruvian coast, raising concerns about its threat to native bivalve species. In contrast, studies on the infestation of P. bioccipitalis on the surf clam Mesodesma donacium, one of the most important species for shellfisheries, suggest a long-term parasitic relationship. The present study analyses infested (i.e. blistered) fossil shells of M. donacium deposited during the Holocene and Middle Pleistocene epochs and critically reviews evidence supporting the hypothesis of the recent introduction of P. bioccipitalis to the Chilean-Peruvian coast. The blistering pattern seen on fossil and recent shells can be considered species-specific for the infestation of M. donacium by P. bioccipitalis. No evidence was actually found on vectors, introduction pathways or distribution range to support the status of P. bioccipitalis as an introduced species. On the contrary, our findings point to a long-term association, at least for several hundred thousand years, between M. donacium and P. bioccipitalis.

Unfortunately, the reporting of parasitism in the fossil record, particularly invertebrate parasites, is scarce (Huntley 2007) and this lack of knowledge gives rise to misinterpretations about the introduced or native origins of parasites.In this study, we report the case of Polydora bioccipitalis (Blake & Woodwick 1971), which has been included in the group of polydorid NIS invading Chilean waters, thus raising concerns about the threat for native and commercial mollusc species (Moreno et al. 2006). The surf clam Mesodesma donacium (Lamarck 1818), one of the most important species for artisanal fisheries of Chile and Peru (McLachlan et al. 1996, Thiel et al. 2007, is commonly infested with P. bioccipitalis (Blake 1983). Recent studies have implied that a parasitic association exists with a certain degree of coadaptation, which is inconsistent with the classification of the polydorid as a NIS. First, experimental data showed that the strong ...

“…Among the polychaetous annelids, which for the most part are free-living, crawling, burrowing and tube-dwelling, the setting-up of close associations with other marine invertebrates is a rather common phenomenon. Four kinds of probable wormborings are known from the Paleozoic Era (600-225 million years ago) (Cameron, 1969).…”

“…Traces produced in marine ecosystems have long been studied (Dapples, 1938;Moore, 1938;MacGinitie, 1945;Barnes and Powell, 1950;Frey, 1968;Ginrgras et al, 2008), but more recent studies have begun to focus on the traces found in continental ecosystems (Ahlbrandt et al, 1978;Ratcliffe and Fagerstrom, 1980;O'Green and Busacca, 2001;Gingras et al, 2002;Hembree and Hasiotis, 2006;Lawfield and Pickerill, 2006;Genise et al, 2009;Hamer and Sheldon, 2010;Buynevich et al, 2011). Trace fossils may be used to infer the presence of organisms whose bodies are rarely fossilized (Cameron, 1969;de Gibert et al, 2000;Chin et al, 2013;Fernández and Pazos, 2013) and to interpret the environmental conditions under which the trace was produced (Turner et al, 1981;Savrda and Bottjer, 1986;Maples and Archer, 1989;Kraus and Hasiotis, 2006;Dashtgard et al, 2008). These interpretations are possible because of studies of living tracemakers in the field and laboratory (Hasiotis, 2007).…”

Burrowing arachnids are important to modern soil ecosystems, but knowledge of these animals in ancient soil ecosystems is limited. In this study, two species of burrowing spiders were studied: Gorgyrella inermis (South African trapdoor spider) and Hogna lenta (field wolf spider). Individuals of each species were studied to investigate their burrowing techniques and behaviors and to categorize the morphologies of their burrows. Experiments were run with variations in sediment density and sediment moisture to evaluate the effects of environmental conditions on burrow morphology. Seven burrow architectures were produced by the spiders: vertical shafts, vertical shafts with terminal chambers, subvertical shafts, subvertical shafts with terminal chambers, Jshaped burrows, Y-shaped burrows, and isolated chambers. All burrow architectures share common features that make them identifiable as spider burrows. Sediment density and moisture had little influence on burrow morphology, but architecture diversity was greatest in sediments of moderate density and moisture. Results from this study show that spiders produce unique biogenic structures that can be distinguished from the burrows of other soil organisms. Data collected from this study can be used to better interpret the paleoecology and evolutionary history of spiders and soil arthropods.
