Abstract

Geographic Information Systems provide the means to explore the spatial distribution of insect species across various land-use types to understand their relationship with shared or overlapping spatiotemporal resources. Blow fly species richness and total fly abundance were correlated among six land-use types (residential, commercial, waste, woods, roads, and agricultural crop types) and distance to streams. To generate multivariate models of species richness and total fly abundance, blow fly trapping sites were chosen across the land-use gradient of Windsor-Essex County (Ontario, Canada) using a stratified random sampling approach. Sampling occurred in mid-June (spring), late August (summer), and late October (fall). Spring species richness correlated highest to residential (-), woods (-), distance to streams (+), and tomato fields (+) in models across all three land-use buffer scale distances (0.5, 1, 2 km), with waste (+/-), roads (-), wheat/corn (-), and commercial (-) correlating at only two of the three scales. Spring total fly abundance correlated with all but one land-use variable across all buffer scale distances, but the distance to streams (+), followed by orchards/vineyards (+) exhibited the greatest importance to these models. Summer blow fly species richness correlated with roads (-) and commercial (+) across all buffer distances, whereas at two of three buffer distances wheat/corn (-), residential (+), distance to streams (+), waste (-), and orchards/vineyards (+) were also important. Summer total fly abundance correlated to models with distance to streams (+), orchards/vineyards (+), and sugar beets/other vegetables (+) at the 2 km scale. Species richness and total abundance models at the 0.5 km buffer distance exhibited the highest correlation, lowest root mean square error, and similar prediction error to those derived at larger buffer distances. This study provides baseline methods and models for future validation and expansion of species-specific knowledge regarding adult blow fly relationships with spatiotemporal resources across land-use types and landscape features.

建立不同土地利用类型的吹蝇(双翅目:Calliphoridae)时空物种丰富度和总丰度模型。
地理信息系统提供了探索昆虫物种在不同土地利用类型中的空间分布的方法,以了解它们与共享或重叠的时空资源之间的关系。在六种土地利用类型(住宅、商业、废弃物、树林、道路和农作物类型)和与溪流的距离之间,蝇类物种丰富度和蝇类总丰度存在相关性。为了建立物种丰富度和苍蝇总丰度的多变量模型,采用分层随机抽样方法在温莎-艾塞克斯郡(加拿大安大略省)的土地利用梯度上选择了吹蝇诱捕点。取样时间分别为六月中旬(春季)、八月下旬(夏季)和十月下旬(秋季)。在所有三个土地利用缓冲区尺度距离(0.5、1、2 千米)的模型中,春季物种丰富度与住宅(-)、树林(-)、溪流距离(+)和番茄田(+)的相关性最高,而废物(+/-)、道路(-)、小麦/玉米(-)和商业(-)仅与三个尺度中的两个相关。在所有缓冲区尺度距离内,除一个土地利用变量外,春季总苍蝇丰度与所有土地利用变量都相关,但与溪流的距离(+),其次是果园/葡萄园(+)对这些模型的重要性最大。在所有缓冲区距离内,夏季吹蝇物种丰富度与道路(-)和商业(+)相关,而在三个缓冲区距离中的两个,小麦/玉米(-)、住宅(+)、溪流距离(+)、废物(-)和果园/葡萄园(+)也很重要。在 2 千米尺度上,夏季苍蝇总丰度与溪流距离(+)、果园/葡萄园(+)和甜菜/其他蔬菜(+)模型相关。在 0.5 千米缓冲距离上的物种丰富度和总丰度模型显示出最高的相关性、最低的均方根误差以及与更大缓冲距离上的模型相似的预测误差。这项研究为今后验证和扩展吹蝇成虫与跨土地利用类型和景观特征的时空资源关系的物种特异性知识提供了基准方法和模型。

期刊介绍: Insects (ISSN 2075-4450) is an international, peer-reviewed open access journal of entomology published by MDPI online quarterly. It publishes reviews, research papers and communications related to the biology, physiology and the behavior of insects and arthropods. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
