“…We considered that keeping bats under this N‐depleted condition for a longer period of time would result in bats being unable to fly for feeding within the experiments and their inminent death. Unexpectedly, our results did not coincide with the response found in other animals that vary their feeding choices to satisfy the requirements of nutrients when they face an unbalanced nutrient availability (Belovsky ; Greenstone ; Geiser & Kenagy ; Wheelwright ; Geiser, Stahl & Learmonth ; Torres‐Contreras & Bozinovic ; Maynts et al . 2009).…”

“…Various studies with spiders (Greenstone ; Mayntz et al . ), birds (Wheelwright ), opossums (Geiser, Stahl & Learmonth ), moose (Belovsky ), mice (Bozinovic, Novoa & Nespolo ) and chipmunks (Geiser & Kenagy ) have demonstrated that feeding choices may vary to satisfy the nutritional requirements depending on the animal's physiological condition.…”

Summary1. Chiropterophilic flowers secrete sugar nectar with low-Nitrogen (N hereafter) content and small amounts of amino acids, which may function to attract animals; nevertheless, the role that micronutrients have on the foraging decisions of Neotropical nectarivorous bats is unknown. 2. We offered the nectar specialist Leptonycteris yerbabueanae and the omnivore Glossophaga soricina pairs of experimental diets mimicking either the N content or the relative abundance of 17 amino acids found in the floral nectar from the main plant species visited by these bats in a tropical dry forest. We addressed the following research questions: (i) Do bats select N-containing or sugar-only nectar differently based on bats' N nutritional status? (ii) Does the presence of N in nectar affect the capacity of bats to discriminate and select other nectar traits such as sugar concentration? and (iii) Are bats able to distinguish among the flavours generated by the amino acid relative abundance present in the nectar from plants they typically encounter in nature? 3. Our results showed that: (i) bats did not consider nectar N content regardless of their N nutritional condition, (ii) the nectar specialist L. yerbabuenae showed a preference for the most concentrated sugar-only nectar but changed to be indifferent when nectar contained N, and (iii) L. yerbabuenae preferred diets without amino acids and preferred the taste of the amino acids present in the nectar of Pachycereus pecten (Cactaceae) over those present in the nectar of Ceiba aesculifolia (Bombacaceae). 4. Our results suggest that regardless of the low concentrations at which N and amino acids are present in floral nectar, their presence affects bats' food selection by interfering with the bats' ability to detect differences in sugar concentrations, and by offering particular flavours that can be perceived and selected by nectarivorous bats. We discuss the ecological implications of the presence of N and amino acids in nectar on bats' foraging decisions.

“…The role of pectin degrading enzymes (polygalacturonases, PG) in the saliva of Lygus bugs was recognized more than four decades ago (Strong & Kruitwagen, 1968, 1970. The direct effects of PG during feeding of L. lineolaris on cotton are square abscission, necrosis at the wound site, deformation of squares and bolls, aborted embryos, and reduced or altered vegetative growth (Strong & Kruitwagen, 1970).…”

“…He concluded that nutrient balance is a prime factor determining food selection in this fly. STRONG c% KRUITWAGEN (1970) likewise demonstrated that the adult of Lygus hesperus (KNIGHT) preferred the higher concentrations of amino acids tested provided the concentration differed by at least 1.2 ~o and the higher concentrations did not exceed 3.0 O//o. However, the bugs failed to discriminate between diets having different concentrations of sucrose, lipids, vitamins, or salts.…”
