Predation in two species of leech under laboratory conditions
Two 60 day experiments on predation behavior of leeches were conducted concurrently. In the first, medicinal leeches, Hirudo orientalis (Utevsky and Trontelj, 2005) were fed to satiation on bovine blood and subsequently transferred into two large opaque plastic containers of equal size but with differing temperatures, 6-7?C and 23-24?C, containing starved Erpobdella octoculata (L.). At the high...
متن کاملLarge-scale rodent control reduces pre- and post-dispersal seed predation of the endangered Hawaiian lobeliad, <i>Cyanea superba</i> subsp. <i>superba</i> (Campanulaceae)
Large-scale rodent control can help to manage endangered species that are vulnerable to invasive rodent consumption. A 26 ha rodent snap-trap grid was installed in montane forest on Oahu Island, Hawaii, in order to protect endangered snails and plants. To assess the effectiveness of this trapping operation in reducing fruit consumption and seed predation of the endangered Hawaiian lobeliad, Cya...
متن کاملWhy didn't I think of that? Avian nest predation and parental activity.
Journal Club Every so often, a hypothesis comes along that contains an idea that makes you wonder why no one has thought of it before. A recent paper by T.E. Martin et al. 1 contains such a conceptual leap. In 1949, A.F. Skutch provided an original hypothesis regarding the evolution of parental care behaviour in birds. The hypothesis was that nest predation should increase with increasing paren...
متن کاملBat Predation by Spiders
In this paper more than 50 incidences of bats being captured by spiders are reviewed. Bat-catching spiders have been reported from virtually every continent with the exception of Antarctica (≈ 90% of the incidences occurring in the warmer areas of the globe between latitude 30° N and 30° S). Most reports refer to the Neotropics (42% of observed incidences), Asia (28.8%), and Australia-Papua New...
متن کاملMales Feeding Females during Incubation. I. Required by Microclimate or Constrained by Nest Predation?
Nest attentiveness (percentage of time spent on the nest) during incubation represents a parent-offspring conflict; incubating birds must balance a trade-off between caring for embryos by staying on the nest versus caring for themselves by getting off the nest to forage. For species in which females are the sole incubator, males can potentially affect this trade-off and increase nest attentiven...
