The Respiratory System of the Arctocephalus australis in Comparison to the Dog as a Land-Carnivore: Are There Adaptations to Marine Life?

open access: yesAnimals, 2023
Marine mammals are divided into three groups, with similar adaptations resulting from their aquatic lifestyle: sirenians, pinnipeds, and cetaceans. The present work focused on the South American fur seal, or Arctocephalus australis, a carnivore included ...

Bushmeat and bycatch: the sum of the parts [PDF]

open access: yes, 2007
In many developing countries, the killing of wild animals for commercial purposes (the bushmeat trade) is a significant factor in the reduction of biodiversity, and probably represents a major threat to the survival of many more populations than we know.

Cranial remain from Tunisia provides new clues for the origin and evolution of Sirenia (Mammalia, Afrotheria) in Africa.

open access: yesPLoS ONE, 2013
Sea cows (manatees, dugongs) are the only living marine mammals to feed solely on aquatic plants. Unlike whales or dolphins (Cetacea), the earliest evolutionary history of sirenians is poorly documented, and limited to a few fossils including skulls and ...

Local competition and metapopulation processes drive long-term seagrass-epiphyte population dynamics [PDF]

open access: yes, 2013
It is well known that ecological processes such as population regulation and natural enemy interactions potentially occur over a range of spatial scales, and there is a substantial body of literature developing theoretical understanding of the interplay ...

Spatial Insurance of Distinct Ecological Functions. [PDF]

open access: yesEcol Lett
We present a new trait‐based framework to quantify spatial functional insurance of distinct ecological functions amongst ecological communities. We identify communities that disproportionately insure (functional sources) or depend on (functional sinks) neighbour communities.

Identification of alimentary components of Antillean manatee diet in the Northeast of Brazil [PDF]

open access: yesBiotemas, 2008
The manatees are considered to be opportunist herbivors, consuming a great amount of alimentary items. The aim of the present study was to identify the alimentary components of the diet of Antillean manatees in free life in the northeastern region of ...
