- Historical Records Of Passerine Introductions To New Zealand Fail To Support The Propagule Pressure
HypothesisBlackburn et al. (Biodiver Conserv 20:2189-2199, 2011) claim that a reanalysis of passerine introductions to New Zealand supports the propagule pressure hypothesis. The conclusion of Blackburn et al. (2011) are invalid for three reasons: First, the historical record is so flawed that there is no sound basis for identifying the mechanisms behind exti […]
- A Reassessment of Historical Records of Avian Introductions to Australia: No Case for Propagule PressureIntroduced species are widely believed to represent a significant threat to conservation of biological diversity. A better understanding of the ecological factors associated with successful species establishment should lead to improved management and mitigation of these introductions. The "propagule pressure hypothesis", implying a greater chance o […]

- Evaluation of Aerial Cluster Sampling of Double-Crested Cormorants on Aquaculture Ponds in MississippiConcern over increasing numbers of double-crested cormorants (Phalacrocorax auritus) and their impacts on channel catfish (Ictalurus punctatus) aquaculture has resulted in increased need for quantitative information to develop and evaluate depredation management efforts. We evaluated aerial surveys in a stratified cluster sampling (SCS) design to estimate an […]
- Evaluation of rhodamine B as a biomarker for raccoonsThe USDA/APHIS/Wildlife Services (WS) oral rabies vaccination program uses tetracycline, a broad-spectrum antibiotic and relatively reliable biomarker, to quantify vaccinebait uptake by raccoons (Procyon lotor). However, obtaining samples (e.g., bone or teeth) to assess tetracycline uptake is highly invasive, and sample preparation can be expensive. By contr […]
- Eradicating Rats on Lehua Island, Hawaii, with the Help of GIS and GPSLehua Island is an uninhabited, 290-acre crescent-shaped volcanic cone located approximately 150 miles north-northwest of Honolulu, Hawaii, or approximately 20 miles west of the island of Kauai. Lehua is a state-designated seabird sanctuary managed by the Hawaii Department of Land and Natural Resources (HIDLNR) and federally owned by the U.S. Coast Guard. Re […]
- Refinement of biomarker pentosidine methodology for use on aging birdsThere is no reliable method for determining age for most species of long-lived birds. Recent success using the skin chemical pentosidine as a biomarker has shown promise as an aging tool for birds. Pentosidine levels have been determined only from the breast tissue of carcasses, and we sought to refine the procedure with respect to biopsy size and location f […]
- Reducing the Risk of Human Exposure to Wildlife DiseasesAs a professional biologist working for a government agency, I am required to carry a card alerting medical personnel that I may have been exposed to certain zoonotic diseases (animal diseases that can infect man) not routinely considered in differential diagnosis. Some of these pathogens are obscure and seldom heard of, such as monkeypox and Q fever; others […]
- Seroprevalence of equine influenza virus in northeast and southern MexicoEquine influenza A virus (EIV) is a highly infectious respiratory pathogen of horses (Hannant and Mumford 1996, Palese and Shaw 2007). The illness is characterised by an abrupt onset of fever, depression, coughing and nasal discharge, and is often complicated by secondary bacterial infections that can lead to pneumonia and death. Two subtypes of EIV, H3N8 an […]
- Capture of ungulates in Central Asia using drive nets: advantages and pitfalls illustrated by the Endangered Mongolian saiga Saiga tatarica mongolicaThe study of mammals suffering intense poaching in remote areas poses an increasingly difficult conservation challenge, in part because the extreme flightiness of such species complicates safe capture. The benefits of handling (an opportunity to obtain biological information and attach radio collars) must be weighed against stress to the animals and potentia […]
DERATIZZATORI AD ULTRASUONI – (DERATTIZZATORI AD ULTRASUONI). PER UNA DERATIZZAZIONE (DERATTIZZAZIONE) IGIENICA ED ECOLOGICA – DISSUASORI MURINI PROFESSIONALI – DERATTIZZATORI MURINI PROFESSIONALI.
La società Contatto s.n.c. per ottemperare (con metodologie più efficienti e moderne) agli obblighi derivanti dall’analisi del rischio per l’igiene alimentare (H.A.C.C.P. Reg. CE 852/04) vi presenta i nostri deratizzatori (scacciatopi – scacciatopi / ultrasuoni e sismici) US2004/U serie Hamelin, PK018, PK019, PK020, PK021 ed altri non in catalogo.
Queste apparecchiature sono di semplice installazione, in quanto occorre solo alimentarle tramite una presa a 230V in corrente alternata (117V a.c. 60Hz a richiesta), o 12V in corrente continua-alternata e posizionarle nel luogo desiderato. La costruzione risulta di tipo anonimo, quindi non facilmente riconoscibile dalla clientela. Non disturba le persone e gli animali domestici.
Il PK018 è studiato espressamente per l’utilizzo all’interno di quadri elettrici e per l’utilizzo in esterno in ambiente protetto da agenti atmosferici.
Dette apparecchiature servono per allontanare i ratti e i topi in locali con copertura nominale di 100m2, per dimensioni maggiori occorrerà installare più apparecchi o sistemi modulari da studiarsi su misura.
Per impianti industriali di grandi dimensioni progettiamo e realizziamo impianti di derattizzazione, ad ultrasuoni e ad infrasuoni di tipo sismico, da esterno e da interno di grande potenza modulati in frequenza e con comando centralizzato e radio-comandato.
Realizziamo altresì impianti di grande potenza ad ultrasuoni ed infrasuoni di tipo sismico per uso agricolo e per piantagioni alimentati con pannelli solari o da tensione di rete.
