“…Few studies have addressed such short‐term and rapid responses to a threat, but Ma et al. () showed that some zooplankton taxa respond rapidly with horizontal movements to alterations in sunlight. Accordingly, we show here that some, but not all, zooplankton taxa respond with strong vertical movements to pulses in UVR threat.…”

“…This suggests that short term (minutes) fluctuations in UVR, such as during a day with variable overcast, will make some zooplankton taxa, but not all, move up and down the water column in response to the instantaneous level of UVR. Few studies have addressed such short-term and rapid responses to a threat, but Ma et al (2013) showed that some zooplankton taxa respond rapidly with horizontal movements to alterations in sunlight. Accordingly, we show here that some, but not all, zooplankton taxa respond with strong vertical movements to pulses in UVR threat.…”

Abstract.Most animals, including aquatic crustacean zooplankton, perform strong avoidance movements when exposed to a threat, such as ultraviolet radiation (UVR). We here show that the genera Daphnia and Bosmina instantly adjust their vertical position in the water in accordance with the present UVR threat, i.e., seek refuge in deeper waters, whereas other taxa show less response to the threat. Moreover, Daphnia repeatedly respond to UVR pulses, suggesting that they spend more energy on movement than more stationary taxa, for example, during days with fluctuating cloud cover, illustrating nonlethal effects in avoiding UVR threat. Accordingly, we also show that the taxa with the most contrasting behavioral responses differ considerably in photoprotection, suggesting different morphological and behavioral strategies in handling the UVR threat. In a broader context, our studies on individual and taxa specific responses to UVR provide insights into observed spatial and temporal distribution in natural ecosystems.

“… In response to climate change, many animals and plants are migrating or shifting their ranges to higher latitudes and elevations 49,50 , while increases in exposure to UV radiation leads zooplankton to migrate into deeper waters [51][52][53][54] . Because of the natural gradients in solar UV radiation that exist with latitude, altitude and water depth 32,35 , these shifts in distributions will expose organisms to conditions of UV radiation to which they are unaccustomed.…”

“…Marine and terrestrial organisms have adapted to prevent and cope with such UVR exposure and damage. These adaptations can be behavioral, such as moving into the shade (Gleason et al, 2006;Ma et al, 2013), physiological, such as absorptive pigmentation like melanin (Singaravelan et al, 2008) and mycosporine-like amino acids (MAAs) (Kuffner, 2002;Hylander and Hansson, 2013), or biochemical such as molecular repair (Carlson and Smith, 1981;Connelly et al, 2009) and antioxidants (Swindells and Rhodes, 2004;Hudelson, 2011).…”

Many spider orb-webs are exposed to sunlight and the potentially damaging effects of ultraviolet B (UVB) radiation. We examined the effect of UVB on the viscoelastic glycoprotein core of glue droplets deposited on the prey capture threads of these webs, hypothesizing that webs built by species that occupy sunny habitats are less susceptible to UVB damage than are webs built by species that prefer shaded forest habitats or by nocturnal species. Threads were tested shortly after being collected in the early morning and after being exposed to UVB energy equivalent to a day of summer sun and three times this amount. Droplets kept in a dark chamber allowed us to evaluate post-production changes. Droplet volume was unaffected by treatments, indicating that UVB did not damage the hygroscopic compounds in the aqueous layer that covers droplets. UVB exposure did not affect energies of droplet extension for species from exposed and partially to mostly shaded habitats (Argiope aurantia, Leucauge venusta and Verrucosa arenata). However, UVB exposure reduced the energy of droplet extension in Micrathena gracilis from shaded forests and Neoscona crucifera, which forages at night. Only in L. venusta did the energy of droplet extension increase after the dark treatment, suggesting endogenous molecular alignment. This study adds UVB irradiation to the list of factors (humidity, temperature and strain rate) known to affect the performance of spider glycoprotein glue, factors that must be more fully understood if adhesives that mimic spider glycoprotein glue are to be produced.
