Repository pattern versus Service layer

What is the difference between the repository pattern and the service layer concept ?

Repository

A Repository is a facade for persistence that implement CRUD access to data/object.

Martin Fowler's Definition.

Service

A service: A class that contains business logic that does not belong to the object model.
A class that implements a set of available operations and coordinates the application's response in each operation.

My guess is that a service could use a repository.

Martin Fowler's Definition.

ASP.NET MVC Web Api / ASP.NET Core Api

In an ASP.NET Core Api, implementing a REST Api, we would find the following layers

• Controllers
• Services
• Repository Implementation
• EMailNotification Service
• Other Services
