With the persistence of fishing penguins, hordes of young people who affected the look of nonmaterialists (snow boarders pierce and tattoo themselves into unemployability, listen to nihilistic music and call things they like "sick") kept alighting at the Salomon tent.
Management efforts to promote persistence of fishes in fire-prone landscapes can take the form of four basic alternatives: (1) pre-fire management; (2) post-fire management; (3) managing fire itself (e.g. fire fighting); and (4) monitoring and adaptive management.
This type of channel restoration may facilitate ecological processes that underpin the persistence of riverine fish populations.
A primary concern among the many potential effects of fire is the effects of fire and fire management on persistence of native fish populations.
The integration of climatic factors directly into the processes and the explicit dispersal process make GR3D an original and relevant tool to assess the repositioning dynamics and persistence of diadromous fish facing climate change.
Anomalous droughts, not invasion, decrease persistence of native fishes in a desert river.
The LCRB is an ideal region to assess ecological threat indices because of the increasing need for conservation to ensure the persistence of native fishes in highly altered habitat.
Population connectivity effected by planktonic dispersal is evidently a key determinant of population recruitment and persistence of Antarctic fishes that inhabit highly seasonal and fragmented environments.
Therefore the paradox of the persistence of small isolated fish populations may be facilitated by a geomorphic mechanism that both limits their connectivity to larger fish populations yet dampens the effect of disturbance by decreasing connections between hillslope and channel processes above geomorphic knickpoints.
Furthermore, to be approved by the corresponding European authorities, fish viral DNA vaccines would also require the study of the persistence in fish of the introduced DNA, their possible impact to the aquatic environment and the acceptance of potential consumers.
