WFClO Fall 2011 FINAL STUDY GUIDE Marine Fisheries and Marine Reserves Botsford MPAs o What they claim to do true answers in parenthesis I Enhanced sustainability yes but so can reducing shing rate I Less uncertainty not the case 7 still dependent on CRT FLEP dispersal chance I Greater shery yield could be less the same or more 0 Provide bene ts of reducing any damage to habitats by shing 0 To predict effects we need to know I FLEP fraction of lifetime egg production distribution over space I Dispersal pattern of larvae MLPA Marine Life Protection Act 1999 o Mandates implementation of marine reserves in CA 0 Put in place to sustain pops esp those of economic value 0 Fisheries management is NOT their goal Conservation Aquatic Ecosystems Freshwater Species Moyle Aquatic biodiversity high in species high in phylogenetic diversity Using sh as indicators 0 Fisheries people care 0 Best studied 0 Relatively easy to monitor 0 Sensitive to many factors 30000 total species of sh 9 about 41 are FRESH WATER Estimated 40 are imperiled globally High loss of diversity in Arid areas western US Tropics Isolated bodies of water Big rivers 0 Urban areas Losing sh in CA because 0 Humans concentrate along the water urbanization 0 Water ows uphill to 0 Waterways waste ow downhill to water 0 Alien invaders drive down natives to extinction and less biodiversity o Underwater means invisible 3 R S OF CONSERVATION o RESERVATION o RESTORATION o RECONCILIATION Conservation strategies What do you focus on 0 Species level Clusters of species Watersheds Ecosystems OOOO OOO Conservation The Tropics Tanzania Caro Katavi National Park Difference levels of protection in the study area 0 Inside National Park only photos well funded amp patrolled 0 Outside Game controlled area tourist big game hunting forest reserve and open area agriculture use National Parks are NOT ENOUGH for conservation of regional diversity From 19772009 9 declines in ALL species NO increases because 0 Water is drying out and not getting to the park damming o Poaching increases over time 0 Tourist hunting Hunting recommendations 0 Police con scate guns 0 Road barriers at local markets 0 Educate about the importance of lions for national economy and try to stop the tribe lion killers money they give to men who kill for good of the Village Damming recommendations 0 Work w politicians to remove o Divert water back to river Conserving Biodiversity A Case Study of the Island Fox Todd AKA HOTTIE TODDIE De nition of conservation biology o The study of biodiversity with the goal of preserving pops species and ecosystems Population level conservation 0 How do we know if a species is declining I Reductions in range and T R U E o How do we know is s are declining I Studying populations can reveal overall L O V E Y o How do pops change size BIDE 9 4 mechanisms of pop change I Birth I Immigration I Death I Emigration o How do we determine what is causing pop change I Rigorous scienti c researc I CASE STUDY THE ISLAND FOX 0 Have no natural predators 0 Species is 20000 years old 0 Found only on Channel Islands 6 total 0 Pop is increasing bc of birth and death weights since isolated location immigration and emigration would not be reasonable Study survival rates radio collars amp live traps Study birth rates radio collars 0 RESULT 9 Survival has decreased Why 0 Golden eagles are alien species that are carnivores Bald eagles were driven out because of DDT pollution to their food source sh in waterways o Feral pigs were brought over to the island Santa Cruz Island and eat the foxes as well They are another alien species Conservation Wetlands and Waterfowl Eadie Loss of wetlands Reasons for the loss 0 Urban development 0 Flood control amp water storage 0 Water diversion 0 Agriculture 79 0 Flood control Value of wetlands 0 Fisheries iraise their young in coastal marshes 0 Wildlife 7 birds mammals reptiles shes other ESP endangered species I 13 of all endangered species live ONLY in wetlands I 50 use wetlands at least sometimes I Over 20 of all North America s waterfowl depend on CA s wetlands 0 Water treatment amp ood control 0 Tourism amp recreation Value of waterfowl o Entire Order of birds that depends on wetlands for survival 150 diff species 0 Tourismhobbies hunting feeding birds birdwatching etc 0 Supports over 700000 jobs What can be done 0 Regulatory programs 0 Public acquisition 0 Buying land 0 Incentives for private land owners 63 wetlands privately owned Alien Species Thanksgiving Turkeys amp other Invaders Increases difficulty of managing natural areas and agricultural crops Best philosophy for management of Putah Creek 0 Leave them alone I Controleradicate most harmful invaders I 21 alien 25 amphibians 9 reptiles 3 birds Novel Ecosystem o Mixture of native amp nonnative species living togethermanage the system as well as you can I page 189 Reconciliation Ecology Wild Turkeys o Nonnative invasive species 0 Omnivore o Introduced from Texas Rio Grande Turkey Key points 0 1 Not all alien invaders are equal I Vertebrates amp trees tend to be treated as individuals Useful aliens are often encouraged o 2 I Alien species are permanent pollution I Hard to eradicate once established Domestic vs Feral cats as alien predators o Possums and pussy cats are endangering the sea otter Law of Unintended Consequence 0 Biological or preventative I Northern Pike a threat to salmon and native shes I Pike eradicated after illegal introduction 22 mill Restoration Ecology Rivers and Streams
