In this review, we focus on the effects of human disturbance on terrestrial apex predators. We summarize their ecological role in nature and how they respond to different sources of human disturbance. Apex predators control their prey and smaller predators numerically and via behavioral changes to avoid predation risk, which in turn can affect lower trophic levels. Crucially, reducing population numbers and triggering behavioral responses are also the effects that human disturbance causes to apex predators, which may in turn influence their ecological role. Some populations continue to be at the brink of extinction, but others are partially recovering former ranges, via natural recolonization and through reintroductions. -

Dietary Specialization and Variation in Two Mammalian Myrmecophages (Variation in Mammalian Myrmecophagy)
Revista Chilena de Historia Natural 59: 201-208, 1986 Dietary specialization and variation in two mammalian myrmecophages (variation in mammalian myrmecophagy) Especializaci6n dietaria y variaci6n en dos mamiferos mirmec6fagos (variaci6n en la mirmecofagia de mamiferos) KENT H. REDFORD Center for Latin American Studies, Grinter Hall, University of Florida, Gainesville, Florida 32611, USA ABSTRACT This paper compares dietary variation in an opportunistic myrmecophage, Dasypus novemcinctus, and an obligate myrmecophage, Myrmecophaga tridactyla. The diet of the common long-nosed armadillo, D. novemcintus, consists of a broad range of invertebrate as well as vertebrates and plant material. In the United States, ants and termites are less important as a food source than they are in South America. The diet of the giant anteater. M. tridactyla, consists almost entirely of ants and termites. In some areas giant anteaters consume more ants whereas in others termites are a larger part of their diet. Much of the variation in the diet of these two myrmecophages can be explained by geographical and ecological variation in the abundance of prey. However, some variation may be due to individual differences as well. Key words: Dasypus novemcinctus, Myrmecophaga tridactyla, Tamandua, food habits. armadillo, giant anteater, ants, termites. RESUMEN En este trabajo se compara la variacion dietaria entre un mirmecofago oportunista, Dasypus novemcinctus, y uno obligado, Myrmecophaga tridactyla. La dieta del armadillo comun, D. novemcinctus, incluye un amplio rango de in- vertebrados así como vertebrados y materia vegetal. En los Estados Unidos, hormigas y termites son menos importantes como recurso alimenticio de los armadillos, de lo que son en Sudamérica. La dieta del hormiguero gigante, M tridactyla, está compuesta casi enteramente por hormigas y termites. -

Invasive ants often become highly abundant in their introduced range and can outnumber native ants. These numerical disparities underlie the competitive asymmetry between inva- sive ants and native ants and result from a complex interplay of behavioral, ecological, and genetic factors. Reductions in the diversity and abundance of native ants resulting from ant invasions give rise to a variety of direct and indirect effects on non-ant taxa. Invasive ants compete with and prey upon a diversity of other organisms, including some vertebrates, and may enter into or disrupt mutualistic interactions with numerous plants and other insects. Experimental studies and research focused on the native range ecology of invasive ants will be especially valuable contributions to this field of study. -

This is the latest in a series of actions before this Court seeking to require the USDA Sheep Experiment Station (“Sheep Station”) to comply with law in its authorization of domestic sheep grazing within vital habitat for bighorn sheep, grizzly bear, greater sage-grouse and other wildlife species. 2. Specifically, Plaintiffs challenge Defendants’ violations of the National Environmental Policy Act (NEPA) and the Administrative Procedure Act (APA) in issuing a July 2017 Final Environmental Statement (FEIS) and July 2018 Record of Decision (ROD) for the “U.S. Sheep Experiment Station Grazing and Associated Activities Project.” Plaintiffs also COMPLAINT – 1 Case 1:19-cv-00065-REB Document 1 Filed 02/20/19 Page 2 of 25 challenge the “Errata” to the FEIS and ROD, which Defendants used to substantially change grazing practices without any public disclosure or comment; and the Supplemental Information Report (SIR) issued along with the ROD, which is also arbitrary and capricious and was relied upon by Defendants to avoid conducting updated NEPA analysis to assess significant new information that arose in the year after the FEIS was issued. -
