“…Although identifying additional partitioning of female oviposition avoidance behavior into microhabitat variables may be difficult in some cases (and may not occur in others), such behavior may be an important source of variation in female fitness. The comprehensive results on amphibians presented in this study, combined with previous work on insects (Lucas and Brodeur ; Hirayama and Kasuya , ), suggest that fine‐scale selection by ovipositing females (i.e., micro‐oviposition avoidance) may be a common feature of the oviposition decisions of many terrestrial and aquatic oviparous organisms.…”

“…Although micro‐oviposition behavior may be most obvious in predator–prey systems, this process is likely to be adaptive in other contexts, including in response to parasitism or where food quality or abiotic characteristics are variable across microhabitats. For example, female water striders adjust the depth of their eggs in response to a parasitic wasp, despite a trade‐off with mortality due to increased water pressure (Hirayama and Kasuya , ). Birds and reptiles are well documented to exhibit nest‐site preferences that are dependent on microclimatic variables (Shine and Harlow ; Wilson ; Lloyd and Martin ), and some female butterflies select plant parts that optimize thermal conditions (e.g.…”

One of the most important defenses for the eggs of ovipositing female organisms is to avoid being laid in the same habitat as their predators. However, for most organisms, completely avoiding an offspring's predators is not possible. One mechanism that has been largely overlooked is for females to partition an oviposition site into microhabitats that differ in quality for offspring survival. We conducted a series of experiments to examine whether female newts avoid microhabitats utilized by their offspring's primary predator, caddisfly larvae. Female newts avoided laying eggs near predatory caddisflies and shifted egg laying upward in the water column when provided with a vertical dimension. Caddisflies were attracted to chemical stimuli from female newts and their eggs, yet primarily used benthic areas in experimental chambers. Finally, results from a field experiment indicate that the behavioral strategy employed by female newts increases offspring survival. This subset of non-genetic maternal effects, micro-oviposition avoidance, is likely an important yet underexplored mechanism by which females increase offspring survival.

“…The decision to lay eggs underwater is probably affected by many additional factors (preconditions) such as the presence of specific aquatic plants, turbidity or water temperature (Dolný et al, 2014). Several studies on the costs and benefits of submerged oviposition in water striders provide indirect evidence of the existence of a trade-off between egg mortality and the risks associated with laying eggs underwater (Fincke, 1986;Miller, 1994;Amano et al, 2008;Hirayama & Kasuya, 2010). The results of several studies indicate that the risk of drowning may be relatively low.…”

The selection of oviposition sites by insects can significantly affect egg mortality. Spreadwing damselflies (Odonata: Lestidae) predominantly lay their eggs in parts of plants growing above the surface of water and only occasionally also those parts growing underwater. Factors affecting the choice of oviposition site and decision to lay underwater are still poorly understood. We examined whether localities with different risk of egg parasitism, different oviposition strategies (above or below the water surface) and the depth at which the eggs were laid, affected the total number of eggs laid, the proportion parasitized and egg mortality. In general, a significantly higher proportion of the eggs laid above the surface of water were parasitized but spreadwing damselflies showed significant preference for laying eggs underwater at both of the sites studied. This preference, however, had a different effect on the overall mortality of eggs at the two sites studied. Hence underwater oviposition by damselflies may be seen as a conditional anti-predator strategy, occurring only if the benefits exceed potential risks. Underwater oviposition may provide additional benefits other than protection against egg parasitism.

Many studies have shown the benefits of selecting suitable sites for offspring survival and growth. However, costs of selecting suitable sites have been little covered. If the female's costs associated with selecting suitable sites exceed the benefit from improvement of offspring performance, selecting such sites can have a negative effect on the ongoing reproductive success for ovipositing females. We investigate the potential costs of selecting suitable sites in the water strider Aquarius paludum insularis. Where there exists a risk of egg parasitism, the female A. paludum will submerge and select a deep site, more suitable for offspring survival, for oviposition. By forcing A. paludum underwater once a day for 10 d, we investigated the potential costs associated with oviposition at deep sites, firstly relating to the performance of submergence (latency to asphyxiation or proportion of buoyancy loss) and, secondly, in the number of eggs laid. Buoyancy became weaker and the latency to asphyxiation became shorter with the number of submergences. The number of eggs laid in the period of forced submergence was smaller than both before and after the period. Selecting deep sites can therefore increase the mortality risk of ovipositing females and also decrease the number of eggs laid in their lives. Selecting suitable sites in all the oviposition bouts can decrease ovipositing females' reproductive success. Costs, not only benefits, should be taken into consideration for understanding oviposition site selection during the lifespan of an ovipositing female.
