In a meta-analysis study on the effects of forest thinning on biodiversity, Verschuyl et al [37] reported a positive or neutral response of mammal, breeding and wintering bird, amphibian, reptile, and insect species to thinning, but thinning intensity drove the magnitude of the response.

Considering the arbitrary approach, landscape heterogeneity appeared as a predictor of species richness only for mammals and breeding birds and at the coarsest spatial scales.
The six sites belong to a consortium that rotates the marine mammals for breeding and has decades-long records of which dolphins have lived together.
Social monogamy has evolved in nonhuman mammals where breeding females are intolerant of each other and female density is low, suggesting that it represents a mating strategy that has developed where males are unable to defend access to multiple females.
According to IUCN, as of 2002, there were 21 threatened species in Puerto Rico: two mammals, eight breeding birds, eight reptiles, and three amphibians.
However, it also scavenges on wild animals such as birds, small carnivores, lagomorphs and small mammals during breeding to feed nestlings, thus facing potential risks of poisoning [18].
The database, created for Biosecurity New Zealand to assist in the effective management of the New Zealand coastline, comprises 14 attributes of marine environmental value derived from 200 unique layers of environmental information ranging from species occurrences and diversity indices to marine-mammal breeding areas and habitat distribution.
In birds, rodents, and seasonally breeding mammals, pinealectomy (pineal gland removal) impairs reproduction.
