IIndividual differenes in progeny viability in Lavandula latifolia: a long.term field study

Author(s): Herrera, Carlos M.
Description: Despite its potential importance as a source of fitness variation in natural plant populations, few studies have so far examined long-term patterns of individual dif- ferences in progeny viability under natural conditions. This paper reports on a six-year field study on the difference...

Measuring the effects of pollinators and herbivorres: evidence for non-additivity in a perennial herb

Author(s): Herrera, Carlos M.
Description: Using an experimental approach, this study addresses the following two questions for the perennial herb Paeonia broteroi (Paeoniaceae) at a location in southeastern Spain. (1) What are the relative magnitudes of the effects of pollinators and herbivores (invertebrates and vertebrates fee...

Thermal biology and foraging responses of insect pollinators to the forest floor irradiance mosaic

Author(s): Herrera, Carlos M.
Description: This paper examines the responses of the insect pollinators of the summer-flowering, understorey shrub, Lavandula latjfolia (Labiatae) to the irradiance mosaic of the forest floor in a southeastern Spanish locality, and assesses the relationship between these responses and interspecific variation i...

Floral Biology, Microclimate, and Pollination by Ectothermic Bees in an Early-Blooming Herb Read More: http://www.esajournals.org/doi/abs/10.2307/1940644

Author(s): Herrera, Carlos M.
Description: Abiotic factors may constrain the functioning of species interactions such as plant—pollinator mutualisms. I investigated how thermal environment affects the interaction between the early—blooming daffodil, Narcissus longispathus (Amaryllidaceae) and its major bee pollinator (Andrena biclor; Andreni...

Microclimate and Individual Variation in Pollinators: Flowering Plants are More than Their Flowers

Author(s): Herrera, Carlos M.
Description: Variation in pollinator composition at the individual plant level is an important prerequisite for plant specialization on pollinators that does not seem to have been investigated previously. I studied variation in pollinator composition in a southeastern Spanish population of the insect-pollinated ...

Dispersal systems in the Mediterranean: Ecological, Evolutionary, and Historical Determinants

Author(s): Herrera, Carlos M.
Description: Investigations on vertebrate seed dispersal systems in the Mediterranean show that extremely efficient plant-disperser mutualisms do not require, and thus are not evidence for, mutual evolutionary adjustments of participants. Current Mediterranean dispersal systems have apparently been shaped by mea...

Selection on Floral Morphology and Environmental Determinants of Fecundity in a Hawk Moth-Pollinated Violet

Author(s): Herrera, Carlos M.
Description: This paper presents the results of a 5—yr field study on the determinants of individual variation in maternal fecundity (seed production) in the narrowly endemic violet Viola cazorlensis (Violaceae), at a southeastern Spanish locality. Flowers of this species are characterized by a very long, thin s...

Activity pattern and thermal biology of a day-flying hawkmoth (Macroglossum stellatarum) under Mediterranean summer conditions

Author(s): Herrera, Carlos M.
Description: 1 The daily activity pattern and aspects of the thermal biology are described for the day-flying hawkmoth, Macroglossum stellatarum L. (Lepidoptera: Sphingidae), while foraging at a flowering population of Lavandula latifolia (Labiatae) under the dry-hot summer conditions of a southeastern Spani...
