Abstract The New Zealand (NZ) sea lion (Phocarctos hookeri) is endemic to NZ and is listed as “Vulnerable” by the International Union for Conservation of Nature. Approximately 99 % of pups are born at the Auckland Islands (a declining population) and Campbell Island (a growing population). The causes of contrasting population trajectory are not well understood, though spatial and temporal variations in prey availability have frequently been implicated for other pinnipeds. This is the first… 

Eastern rockhopper penguins Eudyptes filholi as biological samplers of juvenile and sub-adult cephalopods around Campbell Island, New Zealand

This study indicates that eastern rockhopper penguins can be valuable biological samplers of local juvenile/sub-adult cephalopods around Campbell Island when breeding, that these cep Halopods were likely to be caught naturally (not from fisheries), providing relevant information for the conservation of these penguins.

Predation by New Zealand sea lions and Brown Skuas is causing the continued decline of an Eastern Rockhopper Penguin colony on Campbell Island

Although occasional years of very poor food availability may exert a larger ‘bottom–up’ effect on penguin demographic rates, the ‘top–down’ effects of high avian and pinniped predation rates can be sufficient to drive the decline of small penguin populations.

Cephalopods habitat and trophic ecology: historical data using snares penguin as biological sampler

This study shows that Snares Penguin can be a good local biological sampler of juvenile cephalopods during their breeding season, providing both essential biogeographic information of cEPhalopod diversity and relevant historical information for the conservation of this endemic penguin species.

Leopard Seals (Hydrurga leptonyx) in New Zealand Waters Predating on Chondrichthyans

Leopard seals (Hydrurga leptonyx) are top-order predators that prey on a wide variety of species including crustaceans, cephalopods, fishes, birds, and pinnipeds. While multiple diet studies have

Molecular Analysis of Predator Scats Reveals Role of Salps in Temperate Inshore Food Webs

High precision, high coverage DNA-based diet analysis tools allow greater insight into the food web interactions of cryptic taxa. We used DNA faecal-metabarcoding to look for unrecorded taxa within

Trophic links and the parasites that exploit them: the case of New Zealand's endemic rough skate

This thesis furthers the understanding of parasite trophic transmission through investigating the feeding ecology and parasitic links of a relatively understudied elasmobranch species, the New Zealand’s rough skate, Zearaja nasuta, and uncovered the first case of an adult trypanorhynch tapeworm parasitising rough skates.

Should fatty acid signature proportions sum to 1 for diet estimation?

It is found that the traditional scaling of signature proportions in QFASA can meaningfully bias diet estimators under some conditions and two aspects of the prey types that contributed to a predator’s diet influenced the magnitude of the bias.

Simultaneous estimation of diet composition and calibration coefficients with fatty acid signature data

A new model that allows simultaneous estimation of diet composition and calibration coefficients based only on fatty acid signature samples from wild predators and potential prey is presented, invalidates the primary criticism of QFASA, eliminates the need to conduct feeding trials solely for diet estimation, and consequently expands the utility of fatty acid data to investigate aspects of ecology linked to animal diets.



The population decline of the New Zealand sea lion Phocarctos hookeri: a review of possible causes

The most plausible hypotheses, based on available evidence, are that the observed decline, in particular, the decreasing number of breeding females in the Auckland Island population, is caused by fisheries-induced resource competition and fisheries-related by-catch.

Diet of New Zealand sea lions (Phocarctos hookeri) at the Auckland Islands

Prey taxa identified indicate that New Zealand sea lions are utilising a wide variety of benthic, demersal and pelagic species ranging from the inter-tidal zone to waters deeper than 300 m.

Autumn diet of recolonising female New Zealand sea lions based at Otago Peninsula, South Island, New Zealand

New Zealand (NZ) sea lions (Phocarctos hookeri) are slowly recolonising the Otago coast, South Island, New Zealand. The increase in their numbers may lead to resource competition with other marine

Variability in the diet of New Zealand sea lion (Phocarctos hookeri) at the Auckland Islands, New Zealand

The stomach contents of 121 New Zealand sea lions caught by the squid fishery during the summer/autumn 1997-2006 were examined, finding the common prey-arrow squid and rattail-constitute an abundant resource at the edges of the Auckland Islands shelf, where lactating NZ sea lions forage.

Prey of Auckland Island shags ( Leucocarbo colensoi ) in winter

Diagnostic prey remains of Auckland Island shags (Leucocarbo colensoi) were analysed from 23 regurgitated pellets collected in August 2010 at Enderby Island, Auckland Islands. Allometric equations

Using life-history traits of New Zealand sea lions, Auckland Islands to clarify potential causes of decline

Despite the significant decrease in pup production and breeding animals, not all life-history traits relating to pup mass and survival or female fecundity improved, and research suggests that indirect fishing-related pressures may influence some of these traits.

Contrast in the importance of arrow squid as prey of male New Zealand sea lions and New Zealand fur seals at The Snares, subantarctic New Zealand

This study found that New Zealand sea lions ate minimal squid at a time when squid was clearly available as evidenced by the diet of New Zealand fur seals; hence, there was no indication of resource competition between sea lions and the squid fishery.

Increasing pup production of New Zealand sea lions at Campbell Island/Motu Ihupuku: can it continue?

New Zealand sea lions were relisted as ‘nationally critical’ by the New Zealand Government in 2010, owing to recent severe declines in pup production at the Auckland Islands, but research on Campbell Island/Motu Ihupuku indicates that this population's pup production is increasing.

Conservation status of New Zealand marine mammals (suborders Cetacea and Pinnipedia), 2009

All three endemic NZ marine mammals are now considered threatened with extinction, and future research or management actions that would allow the downlisting of the eight taxa currently listed as Threatened are considered.

The diet of itinerant male Hooker's sea lions, Phocarctos hookeri, at sub-Antarctic Macquarie Island

Prey species previously uncommon in the diet of seals and penguins around Macquarie Island were commonly eaten by Hooker's sea lions, and fish constituted the primary component of the diet.
