“…For example, many insular species and also some mainland lizards from areas (or seasons) poor in arthropods are known to consume nectar, pollen and fruit (e.g. Pérez- Mellado and Corti, 1993;Valido and Nogales, 1994;Traveset and Sáez, 1997;van Damme, 1999;Cooper and Vitt, 2002;Valido, 2003, 2004;Espinoza et al, 2004;O'Grady et al, 2005). Fleshy fruits are, in general, low in fibre and protein, but high in soluble carbohydrates and water content (Jordano, 2000), and are thus easier to digest than foliage and stems.…”

Seed Dispersal: Theory and Its Application in a Changing World

View full text Add to dashboard Cite

This chapter reviews and synthesizes the available evidence for fruit-eating lizards around the world to call attention to the fact that lizards need to be considered as frugivores and potential seed dispersal agents, especially in certain habitats and situations. The geographical distribution of saurochory, the morphological characteristics of fleshy fruits consumed by lizards, the taxonomic affiliation of both lizard and plant species, and the characteristics of their role as seed dispersers, are addressed.

“…Others are omnivorous tending to consume more plant matter in summer or when increasing in size (Perez-Mellado & Corti, 1993;Carretero et al, 2001). Finally, others are almost completely herbivorous at the adult stage (Molina-Borja, 1986;Valido & Nogales, 1994;Perez-Mellado et al, 1999). Perez-Mellado & Traveset (1999) considered that (partial) herbivory in Balearic species does not represent true specialisation based on typical animal helminth communities and lack of apparent morphological adaptations.…”

Lacertids are the dominant group of lizards throughout the Mediterranean Basin. Their role in food web transfer of matter and energy from arthropods and other small invertebrates to birds and mammals constitutes a major function within Mediterranean ecosystems. For many years, prey consumption by lacertids was thought to be almost indiscriminate, not much more than a byproduct of habitat use. However, increasing evidence does not support this passive view. Analyses of prey availability have revealed active prey selection/avoidance in several species. Others show an internal tendency (i.e., historical constraints) to consume specific animal items (ants, clumped prey) or plant matter (seeds, nectar, pollen, leaves). Behavioural experiments showed that lacertids not only identify different prey types by both visual and chemical cues but also modify their feeding behaviour integrating past experiences. Furthermore, size, sex, reproductive state, body condition, tail loss and probably other lizard features are relevant for feeding ecology. However, less attention has been devoted to abiotic factors such as temperature and humidity. More experimental studies of the influences of competitors, predators and parasites on diet are needed. Even though it is controversial, optimal foraging theory provides a conceptual background for future studies. The evolutionary history of the various lacertid lineages, which constrains their morphology and physiology and eventually produces exaptative traits, is to be considered as well. Finally, methodology in field sampling, lab work and statistical analysis needs to be developed. Recommendations are given as to when and where to sample, which compartment should be analysed, which is the appropriate sample size, how to assess trophic availability, which statistical descriptors should be used and how they should be compared.

Cneorum (Rutaceae) in Cuba? The solution to a 150 year old mystery

Cneorum trimerum (Urban) Chodat is only known from the type specimen collected in 1861 in eastern Cuba. The species has sometimes been regarded as a synonym of C. tricoccon L., which is otherwise confined to the Mediterranean. As no other Cneorum specimens are known from Cuba, the specimen is a mysterious finding with a disputed taxonomic rank. The goal of this study is to clarify the status of the Cuban specimen using molecular and wood anatomical data. We succeeded in extracting DNA out of the 150 year old type specimen in our ancient‐DNA lab and amplified two chloroplast markers (atpB, trnL‐trnF) and one nuclear marker (ITS). Comparison of the sequence data with several sequences from C. tricoccon clearly suggests inclusion of the Cuban specimen into the latter species; wood anatomical features confirm the molecular results. The transatlantic distribution of C. tricoccon is probably the result of an introduction in Cuba by humans.
