“…Therefore, although it has been proposed that the drilled and undrilled valves may be transported differentially, leading to distortion of drilling intensity, we think our local ADI values as well as the observed biogeographic patterns are less likely to be affected. A recent study from the eastern Indian coast [ 53 ], analyzing dead molluscan assemblages from 16 of our 36 sampling locations, suggested that although the coastal assemblages are time-averaged, differential degree of time averaging may not be an important factor producing any geographic trend in ADI [see 53 ]. Also, durophagy bias–removal of shells by crushing may artificially inflate DI values [e.g., 54 ]–could influence ADI.…”

“…Полуколичественный и количественный анализ тафономических параметров является хорошим инструментом для понимания посмертного состояния раковинного материала [Davies et al, 1990;Feige, Fürsich, 1991;Kowalewski et al, 1994;Lockwood, Work, 2006;Schneider-Storz et al, 2008;Butler et al, 2020;Mondal et al, 2021]. При этом оцениваются различные тафономические параметры, которые могут включать дисартикуляцию (распад раковины на створки), биоэрозию, потерю периостракума, фрагментацию, окатывание, истирание тонких элементов скульптуры, общую абразию, химическое растворение, дисколорацию, обрастание (encrustation) и др.…”

“…в тафономически активной зоне, TAZ) [Kidwell, Bosence, 1991;Parsons, Brett, 1991;Lazo, 2004;Lockwood, Work, 2006]. Однако в других случаях это правило не работает: например, в сублиторали восточной Индии раковины инфаунных моллюсков повреждены значительнее, чем эпифаунных [Mondal et al, 2021]. Действительно, эпифауна чаще испытывает влияние обрастания (encrustation) и биоэрозии, а на инфаунных моллюсков больше влияет абразия [Lazo, 2004;Lockwood, Work, 2006].…”

“…Despite all these potential biases, time-averaged death assemblages from beach samples have been documented to substitute a conventional sampling effort of regional diversity (Kidwell, 2013) and may provide a stronger signal for species abundance compared to the original living community (Kidwell, 2001). Consequently, beach sampling is considered a valid sampling technique for diversity studies for Recent marine molluscs (Warwick and Light, 2002;Mondal et al, 2021). It is widely utilized for its logistical ease compared to other techniques for acquiring live community data (Warwick and Light, 2002;Zuschin and Ebner, 2015).…”

“…A detailed sampling effort following a consistent protocol is necessary to evaluate the true pattern. It has been documented that "time-averaged" (temporally condensed record of multiple generations of fauna living in the same place) and "spatially-averaged" (spatially accumulated by random postmortem transportation from different habitats at the same time) molluscan death assemblages could yield a near-perfect reflection of the true regional biodiversity despite the potentially different taphonomic history of the specimens (Kidwell and Bosence, 1991;Kidwell and Flessa, 1995;Kidwell, 2001;Warwick and Light, 2002;Mondal et al, 2021). A detailed within-habitat live sampling of marine molluscs along a ∼2500 km stretch of the east coast of India, while desired, proved to be logistically challenging.…”
