NYPD mergency ervices nit, a combination of a Rescue Squad and SWAT Team. ESU has been referred to as the "Oh Shit! Boys." When a cop arrives at a call, takes one look around and says, "Ohhhh shit!" there's probably a need for ESU to respond. There is another saying about ESU. "When the public needs a cop, they call NYPD. When a cop needs a cop, he calls ESU." ESU is perhaps the finest unit of its kind in the world, and regularly cross-trains with the Secret Service, FBI, Customs, INS, IRS, Red Cell and other high-profile SWAT/Tactical teams.
Evolutionary Significant Unit. A population that 1) is substantially reproductively isolated from conspecific populations and 2) represents an important component of the evolutionary legacy of the species.
Evolutionarily Significant Unit. An ESU, or evolutionarily significant unit, is a Pacific salmon population or group of populations that is substantially reproductively isolated from other conspecific populations and that represents an important component of the evolutionary legacy of the species. The ESU policy [pdf] for Pacific salmon defines the criteria for identifying a Pacific salmon population as a distinct population segment (DPS), which can be listed under the ESA.
evolutionarily significant unit. It is a population (or group of populations) that: 1) is substantially reproductively isolated from other conspecific population units, and 2) represents an important component in the evolutionary legacy of the species (R. Waples, Pacific salmon, Oncorhynchus spp., and the definition of "species" under the Endangered Species Act, Mar. Fish. Rev. 53(3), 1991).
Evolutionary Significant Units
EVOLUTIONARILY SIGNIFICANT UNIT. A population or group of populations of salmon that 1) is substantially reproductively isolated from other populations and 2) contributes substantially to the evolutionary legacy of the biological species. (This concept is used by NMFS in its administration of the ESA for anadromous salmon populations.)
Employer Services Unit – various staff within RSC who provide placement and job development services for consumers, and market RSC's services to employers.
Evolutionarily Significant Unit. NMFS definition of a distinct population segment that is smallest biological unit that will be considered to be a " species" under the Endangered Species Act. A population will be is considered to be an ESU if 1) it is substantially reproductively isolated from other conspecific population units, and 2) it represents an important component in the evolutionary legacy of the species.
