Dear Marmam subscribers,

My coauthors and I are pleased to announce the publication of the following
paper on bottlenose dolphins in the Bay of Islands, NZ and the efficacy of
protected areas on dynamic marine megafauna.

Hartel EF, Constantine R, Torres LG. 2014. Changes in habitat use patterns
by bottlenose dolphins over a 10-year period render static management
boundaries ineffective. *Aquatic Conservation: Marine and Freshwater
Ecosystems*. DOI: 10.1002/aqc.2465


ABSTRACT

1. Bottlenose dolphins (*Tursiops truncatus*) in northern New Zealand range
widely and their coastal distribution increases their risk of exposure to a
variety of threats.
2. Marine protected areas (MPAs) are increasingly used to protect species
but there is a paucity of studies examining their efficacy.
3. In the Bay of Islands, New Zealand (35°14’S, 174°06’E), dolphin
distribution and habitat use patterns were examined between two time
periods: 1996–2000 and 2007–2010. In addition, dolphin use of tourism
exclusion zones designed to protect the dolphins were assessed.
4. Spatial distribution was analysed using kernel densities and Mantel
tests.
5. Broad-scale distribution patterns remained constant between the two
periods but fine-scale dolphin distribution patterns shifted considerably.
6. The exclusion zones that were established based on results from the
1996–2000 study were rarely used in 2007–2010, and therefore no longer
provided dolphins protection from tourism.
7. This research demonstrates the plasticity in dolphin habitat use
patterns through time and the importance of re-evaluating the efficacy of
static protected areas, especially for wide-ranging species.
