Mátyás Prommer, Auteur ; Janos Bagyura, Auteur ; Marc Kéry, Auteur ; Madan K. Oli, AuteurThe disappearance of the breeding population of Peregrine Falcon Falco peregrinus from Hungary in 1964 is likely to have been caused by extensive agricultural use of organochlorine pesticides. After proving harmful to humans and wildlife, organo[...]

Mansoor H. AlJahdhami, Auteur ; Dana L. Karelus, Auteur ; Waheed A. AlFazari, Auteur ; Lily-Arison Rene de Roland, Auteur ; Gilbert Razafimanjato, Auteur ; Michael J. McGrady, Auteur ; Madan K. Oli, AuteurCapsule Sooty Falcon Falco concolor movement patterns were strongly dependent on the phase of their annual cycle, and were clearly discernible in terms of the average hourly travel speeds of falcons during those phases.Aims To better understand [...]

Michael J. McGrady, Auteur ; Waheed Al Fazari, Auteur ; Mansoor Al Jahdhami, Auteur ; Martin Fisher, Auteur ; Andy Y. Kwarteng, Auteur ; Hartmut Walter, Auteur ; Madan K. Oli, AuteurColonial island-breeding birds can be particularly vulnerable to anthropogenic disturbance, which can adversely affect their nesting success. We studied Sooty Falcons Falco concolor breeding on 10 ground-predator-free islands in the Sea of Oman [...]

Oli, AuteurDans Ibis (159(4) 2017)Knowledge of demographic parameters affecting population dynamics is critical to the formulation of effective conservation strategies. Sooty Falcon Falco concolor is a little-studied, Near-threatened species; estimates of global population size [...]

Michael J. McGrady, Auteur ; James E. Hines, Auteur ; Chris J. Rollie, Auteur ; George D. Smith, Auteur ; Elise R. Morton, Auteur ; Jennifer F. Moore, Auteur ; Richard M. Mearns, Auteur ; Ian Newton, Auteur ; Oscar E. Murillo-García, Auteur ; Madan K. Oli, AuteurOrganochlorine pesticides disrupted reproduction and killed many raptorial birds, and contributed to population declines during the 1940s to 1970s. We sought to discern whether and to what extent territory occupancy and breeding success changed [...]
Article
Ian Newton, Auteur ; Michael J. McGrady, Auteur ; Madan K. Oli, AuteurThis paper reviews the literature on survival estimates for different species of raptors and owls, examines the methods used to obtain the estimates, and draws out some general patterns arising. Estimating survival usually involves the marking o[...]
Article
Robert McCleery, Auteur ; Jeffrey A. Hostetler, Auteur ; Madan K. Oli, AuteurThe critical question for the success of all captive breeding and release programs (CBRPs) is the same: will the benefit of augmenting or reestablishing a population with captive animals outweigh the loss of taking individuals from the wild? Yet[...]
Article
Jeffrey A. Hostetler, Auteur ; David P. Onorato, Auteur ; Deborah Jansen, Auteur ; Madan K. Oli, AuteurGenetic restoration has been suggested as a management tool for mitigating detrimental effects of inbreeding depression in small, inbred populations, but the demographic mechanisms underlying population-level responses to genetic restoration rem[...]
Article
Varun R. Goswami, Auteur ; Sachin Sridhara, Auteur ; Kamal Medhi, Auteur ; A. Christy Williams, Auteur ; Ravi Chellam, Auteur ; James D. Nichols, Auteur ; Madan K. Oli, AuteurGlobal conservation policy is increasingly debating the feasibility of reconciling wildlife conservation and human resource requirements in land uses outside protected areas (PAs). However, there are few quantitative assessments of whether or to[...]

Jeffrey A. Hostetler, Auteur ; J. Walter McCown, Auteur ; Elina P. Garrison, Auteur ; Aletris M. Neils, Auteur ; Mark A. Barrett, Auteur ; Melvin E. Sunquist, Auteur ; Stephanie L. Simek, Auteur ; Madan K. Oli, AuteurAnthropogenic habitat fragmentation poses a serious threat to conservation of large carnivores, due to their extensive movements and potential conflicts with humans. We studied the population ecology of Florida black bears (Ursus americanus flor[...]
Article
Aditya Singh, Auteur ; Tommy C. Hines, Auteur ; H. Franklin Percival, Auteur ; Madan K. Oli, AuteurContext. Nest-site selection can influence nesting success, and thus population dynamics, of many species of ground-nesting birds. Despite the economic importance as a game species, populations of northern bobwhites have been declining throughou[...]
Article
Virginie Rolland, Auteur ; Jeffrey A. Hostetler, Auteur ; Tommy C. Hines, Auteur ; Fred A. Johnson, Auteur ; H. Franklin Percival, Auteur ; Madan K. Oli, AuteurContext. Hunting-related (hereafter harvest) mortality is assumed to be compensatory in many exploited species. However, when harvest mortality is additive, hunting can lead to population declines, especially on public land where hunting pressur[...]

Jeffrey A. Hostetler, Auteur ; David P. Onorato, Auteur ; James D. Nichols, Auteur ; Warren E. Johnson, Auteur ; Melody E. Roelke, Auteur ; Stephen J. O'Brien, Auteur ; Deborah Jansen, Auteur ; Madan K. Oli, AuteurEstimates of survival for the young of a species are critical for population models. These models can often be improved by determining the effects of management actions and population abundance on this demographic parameter. We used multiple sou[...]
Article
Virginie Rolland, Auteur ; Jeffrey A. Hostetler, Auteur ; Tommy C. Hines, Auteur ; H. Franklin Percival, Auteur ; Madan K. Oli, AuteurContext. Despite their economic importance and intensive management, many game bird species, including the northern bobwhite Colinus virginianus, are in decline. Declines may be explained, at least in part, by low survival due perhaps to poor ha[...]
Article
Varun R. Goswami, Auteur ; Divya Vasudev, Auteur ; Madan K. Oli, AuteurMultiple-use zones around protected areas are designed to balance human resource needs with wildlife conservation, but conflicts between wildlife and people in these areas of co-occurrence (CA) can seriously undermine their conservation potentia[...]
Article
Kristen Aaltonen, Auteur ; Andrew A. Bryant, Auteur ; Jeffrey A. Hostetler, Auteur ; Madan K. Oli, AuteurRecovery of the endangered Vancouver Island marmot (Marmota vancouverensis) is contingent upon releases of captive-born marmots into natural habitats. Success of such re-introduction programs largely depends on the ability of released animals to[...]
