欧洲农业正在经历广泛的变化，这可能会对农田生物多样性产生深远影响。开发工具，以便在发生变化之前评估不同土地利用替代品对生物多样性的潜在影响，对指导管理决策至关重要。在这项研究中，我们开发了一个基于资源的模型框架，根据物种关键资源需求(食物、觅食栖息地和筑巢地点)的简单信息，估计目标物种的栖息地适宜性，并检验是否可以将土地利用和当地物种的分布联系起来。我们以伊比利亚半岛东北部低地地区的四种草原鸟类为研究对象。我们还比较了我们的基于资源的方法和通过基于栖息地的模型获得的性能，这些模型涉及物种的发生和土地覆盖变量。此外，我们使用基于资源的方法来预测耕作系统的变化对农田鸟类栖息地适宜性的影响，并将这些预测与基于栖息地的模型得到的结果进行比较。在预测当前物种分布时，我们基于资源的模型生成的栖息地适宜性评估结果与基于栖息地的模型预测当前物种分布时的表现相似(对于一个研究物种来说更好)。在基于资源的模型中，四个物种中有三个获得了适度的预测成功，在基于栖息地的模型中，四个物种中有两个获得了适度的预测成功。尽管基于资源的模型的性能有改进的潜力，但它们提供了一种结构，用于利用农业实践、关键资源的提供和生物反应之间的功能联系的现有知识来预测在各种情况下改变土地利用的潜在影响，或变化的影响，例如不易纳入基于生境的模型的管理做法的改变。
European agriculture is undergoing widespread changes that are likely to have profound impacts on farmland biodiversity. The development of tools that allow an assessment of the potential biodiversity effects of different land-use alternatives before changes occur is fundamental to guiding management decisions. In this study, we develop a resource-based model framework to estimate habitat suitability for target species, according to simple information on species’ key resource requirements (diet, foraging habitat and nesting site), and examine whether it can be used to link land-use and local species’ distribution. We take as a study case four steppe bird species in a lowland area of the north-eastern Iberian Peninsula. We also compare the performance of our resource-based approach to that obtained through habitat-based models relating species’ occurrence and land-cover variables. Further, we use our resource-based approach to predict the effects that change in farming systems can have on farmland bird habitat suitability and compare these predictions with those obtained using the habitat-based models. Habitat suitability estimates generated by our resource-based models performed similarly (and better for one study species) than habitat based-models when predicting current species distribution. Moderate prediction success was achieved for three out of four species considered by resource-based models and for two of four by habitat-based models. Although, there is potential for improving the performance of resource-based models, they provide a structure for using available knowledge of the functional links between agricultural practices, provision of key resources and the response of organisms to predict potential effects of changing land-uses in a variety of context or the impacts of changes such as altered management practices that are not easily incorporated into habitat-based models.
