Photosynthetic pathway diversity in a seasonal pool community Photosynthetic pathway diversity in a seasonal pool community

1. Photosynthetic pathway diversity was evaluated for the dominant species in a seasonally aquatic community in the south-western USA using 14C pulse-chase techniques. 2. Under submerged conditions, only about half of the species were clearly C3, three of the 15 dominants were CAM, one species was C4 and three were potentially assimilating carbon with both C3 and C4 fixation. 3. During...

Role of charred wood, heat-shock and light in germination of postfire phrygana species from the eastern Mediterranean Basin Role of charred wood, heat-shock and light in germination of postfire phrygana species from the eastern Mediterranean Basin

Seeds of 22 species collected from recently burned phrygana were tested for their response to fire-type cues of charred wood and heat-shock. All Cistus species were stimulated by brief heat-shock, as shown in previous studies; however, none responded to charred wood. Only one of the 22 species was stimulated by charred wood, and only in dark-inhibited seeds, and this response did not...

Effects of Protective Fencing on Birds, Lizards, and Black-Tailed Hares in the Western Mojave Desert Effects of Protective Fencing on Birds, Lizards, and Black-Tailed Hares in the Western Mojave Desert

), perennial plant cover, and structural diversity of perennial plants were evaluated from spring 1994 through winter 1995 at the Desert Tortoise Research Natural Area (DTNA), in the Mojave Desert, California. Abundance and species richness of birds were higher inside than outside the DTNA, and effects were larger during breeding than wintering seasons and during a high than a low...

Avian cholera mortality in lesser snow geese nesting on Banks Island, Northwest Territories Avian cholera mortality in lesser snow geese nesting on Banks Island, Northwest Territories

Avian cholera is one of the most important diseases affecting waterfowl in North America, but little is known about its ecology and its impact on waterfowl populations. We documented avian cholera mortality in breeding lesser snow geese (Chen c. caerulescens) at the Egg River colony on Banks Island, Northwest Territories, Canada, in 1995 and 1996. Area of the breeding colony, core...
