Diversity and Distribution Patterns of Invasive Alien Plant Species Along Dispersal Corridors in Parsa National Park, Central Nepal. [PDF]

Ecol Evol
Protected areas face growing pressure from invasive alien plant species (IAPS), whose distribution differs across dispersal corridors. This study reveals that road verges and riversides were the most heavily invaded areas (70% of recorded species), with Chromolaena odorata being the most dominant IAPS.

Postcranial remains of basal typotherian notoungulates from the Eocene of northwestern Argentina [PDF]

Acta Palaeontologica Polonica, 2020
Notoungulates represent the most taxonomically diverse and temporally and geographically widespread group among South American native ungulates. Here, we analyze anatomical and systematic aspects of proximal tarsal bones recovered from the Lower and ...

Tracing the Paleobiology of Paedotherium and Tremacyllus (Pachyrukhinae, Notoungulata), the Latest Sciuromorph South American Native Ungulates – Part I: Snout and Masticatory Apparatus

Journal of Mammalian Evolution, 2020
Inquiring into the paleoecology of extinct forms is always a challenge, particularly when the taxa under study correspond to derived ecomorphs of ancient and completely extinct clades. In this contribution, the configuration of the masticatory apparatus and associated features of the Neogene pachyrukhines Paedotherium and Tremacyllus are studied in a ...

Effects of large herbivores on grassland arthropod diversity [PDF]

, 2015
Both arthropods and large grazing herbivores are important components and drivers of biodiversity in grassland ecosystems, but a synthesis of how arthropod diversity is affected by large herbivores has been largely missing. To fill this gap, we conducted

A mitogenomic timetree for Darwin’s enigmatic South American mammal Macrauchenia patachonica

Nature Communications, 2017
Classification of the extinct South American native ungulates (SANUs) has posed a challenge given the absence of close, surviving relatives. Here, Westburyet al.

Hypercarnivorous apex predator could provide ecosystem services by dispersing seeds [PDF]

, 2016
Large ?hypercarnivorous? felids are recognized for their role as apex predators and hence as key elements in food webs and ecosystem functioning through competition and depredation.
