Exometabolite niche partitioning among sympatric soil bacteria
Soils are arguably the most microbially diverse ecosystems. Physicochemical properties have been associated with the maintenance of this diversity. Yet, the role of microbial substrate specialization is largely unexplored since substrate utilization studies have focused on simple substrates, not the complex mixtures representative of the soil environment. Here we examine the exometabolite compo...
متن کامل[Dietary differences and niche partitioning in three sympatric Myotis species].
The morphology and diet characteristics of three Myotis species roosting in the same cave were studied in Anlong County, Guizhou from September to November 2005. The three mouse-eared bats were the Chinese water myotis (Myotis laniger) "body mass: (4.46±0.53) g, forearm: (34.63±1.45 mm)", fringed long-footed myotis (Myotis fimbriatus) "body mass: (5.15±1.76) g, forearm: (35.20±1.07) mm" and sze...
متن کاملChemical niche differentiation among sympatric species of orchid bees.
Male Neotropical orchid bees (Euglossini) collect volatile substances (fragrances) from flowers and other sources (e.g., decaying wood) and store them in specialized hind tibial pockets. The accumulated chemicals are later emitted during courtship display, presumably to lure conspecific females for mating. We analyzed tibial fragrances of males of 15 sympatric Panamanian species in the genus Eu...
متن کاملGametophyte ecology and demography of epiphytic and terrestrial tropical ferns.
Factors that influence the distribution of ferns are poorly understood and likely reflect the ecology of both the sporophyte and the gametophyte generation. Little study has been done on the ecology of the gametophyte generation, especially in regard to tropical species. The goal of this study was to examine demography and the influence of light and disturbance on the distribution of the gameto...
متن کاملPatterns of Niche Overlap among Broadly Sympatric versus Narrowly Sympatric Kalahari Lizards (scincidae: Mabuya)'
Two semiarboreal skinks (Mabuya) are narrowly sympatric in the Kalahari desert, whereas two terrestrial species are broadly sympatric both with one another and with the semiarboreal species. We attempt to discern reasons for these differing distributional patterns. The narrow zone of sympatry of the semiarboreal species is partially congruent with zones of habitat change (rainfall and vegetatio...
