The influence of choice on feeding preferences of marine herbivores
These data describe the preferences of two herbivores, the wavy turban snail Megastraea undosa and the Pacific purple urchin Strongylocentrotuts purpuratus for 14 macroalgal species relative to giant kelp Macrocystis pyrifera and the role chemical defenses play in influencing herbivory. Data cover the raw grams consumed and total phenolic content of 15 total macroalgal species found in the Santa Barbara Channel and are taken from three Santa Barbara Coastal Long Term Ecological Research sites (Mohawk Reef, Arroyo Burro Reef, and Naples Reef).

Data from: Seed preference is only weakly linked to seed-type-specific feeding performance in a songbird
<p>The dehusking of seeds by granivorous songbirds is a complex process that requires fast, coordinated and sensory-feedback-controlled movements of beak and tongue. Hence, efficient seed handling requires a high degree of sensorimotoric skill and behavioural flexibility, since seeds vary considerably in size, shape and husk structure. To deal with this variability, individuals might specialise on specific seed types, which could result in greater seed handling efficiency of the preferred seed type, but lower efficiency for other seed types. To test this, we assessed seed preferences of canaries (Serinus canaria) through food choice experiments and related these to data of feeding performance, seed handling skills and beak kinematics during feeding on small, spindle-shaped canary seeds and larger, spheroid-shaped hemp seeds. We found great variety in seed preferences among individuals: some had no clear preference, while others almost exclusively fed on hemp seeds, or even prioritized novel seed types (millet seed). Surprisingly, we only observed few and weak effects of seed preference on feeding efficiency. This suggests that either the ability to handle seeds efficiently can be readily applied across various seed types, or alternatively, it may indicate that achieving high levels of seed-specific handling skills does not require extensive practice.</p>

FIGURE 2. Bivariate plot showing the mean and the standard error of the mean for the complexity (Asfc) and anisotropy (epLsar) variables. The symbol type (circle/square) represents the region, the filling of the symbol differentiates between hipparionin size types, and the color if they are from Vallesian (grey) or Turolian (black) assemblages. Extant wild Equus africanus asinus (A) and Equus quagga burchelli (B) are included for comparison.

Fig. 3. Pupal weights recorded in no-choice assays afer placement of Helicoverpa zea 4th instars on a single soybean tissue type. Letters represent means separation by the Tukey HSD test (α = 0.05) and error bars represent SE. Data marked by an asterisk (*) were omitted from the analysis because no individuals survived to pupation.
