    Reason for
    ?
    • 1.Island biogeography theory models reserves as analogous to islands surrounded by anthropogenically transformed lands
      ?

      Think about whether this reason is strong or weak

    • 2.Island biogeography theory predicts that larger areas support more species
      ?

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Island biogeography theory predicts species richness but does not predict which species persist, allowing large reserves to favor generalists over rare specialists.
      ?

      Think about whether this reason is strong or weak

    • 2.Conservation goals require maximizing persistence of threatened species, not maximizing total species counts.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore, multiple smaller reserves strategically placed across heterogeneous habitats may better protect threatened specialists than one large reserve.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.The SLOSS debate (Simberloff & Abele, 1976) demonstrated empirically that several small reserves can collectively harbor more species than a single large reserve of equal total area.
      ?

      Think about whether this reason is strong or weak

    • 2.Land acquisition for conservation operates under conditions of severe resource scarcity, making opportunity costs morally relevant to reserve design.
      ?

      Think about whether this reason is strong or weak

    • 3.A blanket normative prescription to maximize reserve size ignores that resources spent on one large reserve preclude protecting multiple distinct bioregions.
      ?

      Think about whether this reason is strong or weak

    Nevertheless, in the 1970s, island biogeography began to be viewed as a model for biological reserves which, by being surrounded by anthropogenically transformed lands, were supposed to be similar to islands—see the entry on conservation biology. The initially prevalent view, based on island biogeography theory, was that reserves should be as large as possible.[66] In particular, one conclusion drawn from island biogeography theory was that “[i]n cases where one large area is infeasible, it
