Lunar phobia in the greater fishing bat Noctilio leporinus (Chiroptera: Noctilionidae).
The nightly activity patterns of Noctilio leporinus, a piscivorous neotropical bat, were documented by visual observation over one lunar cycle at a large dock in Golfito, Costa Rica. The activity patterns were compared to the intensity of the moonlight, and a strong correlation between darkness and activity was observed (n = 776, r2 = 0.96). This correlation has been observed in many species of...
متن کاملDiet of the fishing bat Noctilio leporinus (Linnaeus) (Mammalia, Chiroptera) in a mangrove area of southern Brazil
From January to December 1999, the diet of Noctilio leporinus (Linnaeus, 1758) was determined in a salt-water ecosystem, by analysing the feces of bats captured in mist nets. Of the 61 samples analyzed, most contained remains of fish (90.2%), followed by insects (70.5%) and crustaceous (29.5%). The most frequent fishes species were: silversides Atherinella brasiliensis (Quoy & Gaimard, 1825), a...
متن کاملHost characteristics do not affect community structure of ectoparasites on the fishing bat Noctilio leporinus (L., 1758) (Mammalia: Chiroptera).
Patterns of parasite abundance and prevalence are thought to be influenced by several host characteristics such as size, sex, developmental stage, and seasonality. We examined two obligatory ectoparasites of the bat Noctilio leporinus (L.) (Chiroptera, Noctilionidae) to test whether prevalence and abundance of Noctiliostrebla aitkeni Wenzel and Paradyschiria fusca Speiser (Diptera, Streblidae) ...
متن کاملStreblid bat fly assemblage structure on Paraguayan Noctilio leporinus (Chiroptera: Noctilionidae): nestedness and species co-occurrence
Evaluation of proximate mechanisms (e.g. dispersal, immigration, competition, facilitation) that determine patterns of assemblage or community structure is an important step in the development of paradigms in ecology. Host– parasite systems are useful for such studies because host-parasite assemblages are easily defined units of study, each host individual harbours a sample from a community or ...
متن کاملAudiogram of the big brown bat (Eptesicus fuscus).
The audiograms of three big brown bats (Eptesicus fuscus) were determined using a conditioned avoidance procedure. The average audiogram ranged from 0.850 kHz at 106 dB to 120 kHz at 83 dB SPL, with a best threshold of 7 dB at 20 kHz and a distinct decrease in sensitivity at 45 kHz. The results confirm those of a previous study by Dalland (1965a) that the big brown bat has good high-frequency h...
