草地动物种群数量调查文献

以下是一些草地动物种群数量调查的文献：

1. "Grassland bird population trends in the eastern United States" by Peter D. Vickery, James R. Herkert, and James W. Terrell. This study examines the population trends of grassland birds in the eastern United States over a 25-year period. The authors found that many grassland bird species have experienced significant declines in population size.

2. "Effects of livestock grazing on grassland bird populations in Alberta, Canada" by Erin M. Bayne and Peter S. Solymos. This study investigates the impact of livestock grazing on grassland bird populations in Alberta, Canada. The authors found that grazing has a negative impact on many grassland bird species, and that the intensity and timing of grazing can have significant effects on population size.

3. "Grassland biodiversity and ecosystem services" by Peter Manning, James S. Bullock, and Richard F. Pywell. This review article examines the relationship between grassland biodiversity and ecosystem services. The authors argue that maintaining high levels of biodiversity in grassland ecosystems is essential for providing a range of ecosystem services, including carbon sequestration, soil fertility, and pollination.

4. "Population dynamics of small mammals in a temperate grassland ecosystem" by Marcin Tobolka, Piotr Tryjanowski, and Tomasz Postawa. This study investigates the population dynamics of small mammals in a temperate grassland ecosystem in Poland. The authors found that population size of small mammals is influenced by a range of environmental factors, including habitat structure, vegetation cover, and predator abundance.

5. "Effects of fire on grassland bird populations in North America" by James R. Herkert and Peter D. Vickery. This study examines the impact of fire on grassland bird populations in North America. The authors found that prescribed burning can have positive effects on grassland bird populations by creating suitable breeding and foraging habitat, but that uncontrolled wildfires can have negative effects by destroying habitat and causing mortality
