| 2 | 黑斑羚粪便中碳同位素揭示的食性变化(英文)显示文摘利用稳定碳同位素数据(δ13C)分析了南非克鲁格国家公园混食性黑斑羚(Aepyceros melampus)时间和空间尺度上的食性变化,验证了两个假说,即有蹄类食性变化是由生境中木本植物与草本植物的相对配比导致;降雨控制有蹄类生态。结果表明:黑斑羚的食性涵盖了精食者-粗食者采食谱系,且食性中木本与草本比例在不同月间、季节、年度和区域间存在很大变化。栖息于开放性热带稀树草原和草原中的黑斑羚通常采食比生境中更高比例的草本,但在时间尺度上并不恒定。在克鲁格北部的一个区域(Punda Maria) ,黑斑羚采食的草本比克鲁格国家公园中其它任何区域都多。与其它生境相比,在河边的黑斑羚采食草本数量更少,尤其是在食性空间变化更为明显的旱季。因此,我们的数据不支持有蹄类食性组成变化是由生境中木本与草本比例不同造成的假说,食性与降雨量间也无明显的关系。我们的结果支持草本中蛋白含量增加引起黑斑羚采食比例的增加这一模型。粪便中氮含量在时间和空间上的变化很小,揭示在可利用食物中,无论木本还是草本,黑斑羚进行选择采食以保证最好的食物质量。基于这些结果,我们认为更具体的食物选择和可利用性最适采食理论能够更好地解释这种生态学变化。 | Daryl CODRON Jacqui CODRON Julia A.

| 4 | Carnivore stable carbon isotope niches reflect predator–prey size relationships in African savannas显示文摘Predator-prey size relationships are among the most important patterns underlying the structure and function of ecological communities.Indeed,these relationships have already been shown to be important for understanding patterns of macroevolution and differential extinction in the terrestrial vertebrate fossil record.Stable isotope analysis(SIA)is a powerful remote approach to examining animal diets and paleodiets.The approach is based on the principle that isotope compositions of consumer tissues reflect those of their prey.In systems where resource isotope compositions are distributed along a body size gradient,SIA could be used to reconstruct predator-prey size relationships.We analyzed stable carbon isotope distributions amongst mammalian herbivores in extant and Plio-Pleistocene African savanna assemblages,and show that the range ofδ^(13)C values among mammalian prey species(herbivores and rodents)increases with body mass(BM),because C_(4) plant feeding(essentially grazing)is more common among larger taxa.Consequently,δ^(13)C values of mammalian carnivores in these systems are related to species’BM,reflecting a higher average C_(4) prey component in the diets of larger-bodied carnivores.This pattern likely emerges because only the largest carnivores in these systems have regular access to the C_(4) prey base,whereas smaller carnivores do not.Theδ^(13)C-BM relationship observed in mammalian carnivores is a potentially powerful approach for reconstructing and parameterizing predator-prey size relationships in contemporary and fossil savanna assemblages,and for interpreting how various behavioral,ecological and environmental factors influence prey size selection. | Jacqueline CODRON Nico L AVENANT Corli WIGLEY-COETSEE Daryl CODRON | 2018 | Integrative Zoology2018，13，2： | 0 |
