Повний текст джерелаAlthough the cost of reproduction constrains animals to breed during spring/summer when food availability peaks, exception exist in seabirds with few species engaged in breeding during winter months. How their elevated energy needs can be sustained during a period traditionally reported for food shortage and challenging at-sea conditions is poorly understood. In addition, this unusual breeding phenology is adopted by more species in New Zealand than elsewhere in the world, with a concentration on the South island west coast where several winter breeding species are reported to forage with overlap. Therefore, the objectives of this thesis were to: 1) describe the fine-scale foraging behaviour of winter-breeding species from the west coast of New Zealand’s South Island, 2) investigate the intrinsic and extrinsic factors driving their foraging, and 3) quantify their niche overlap as they exploit similar areas during elevated energetically demand. Using bio-logging data (GPS, accelerometer, dive recorder) combined with stable isotopes (carbon and nitrogen from whole blood), the winter foraging strategies of breeding males and females were investigated in a deep diver (Fiordland penguin Eudyptes pachyrhynchus) and two surface-feeders / shallow divers (Westland petrel Procellaria westlandica and southern Buller’s albatross Thalassarche b. bulleri). The tracked individuals foraged close to their colony compared to their summer breeding congenerics, using primarily the nearby shelf-slope and neritic waters. Males and females displayed similar foraging behaviour in penguins and petrels, while spatial sexual differences occurred for albatross. All three species encountered prey at a high rate, allowing raising offspring with good success and without higher foraging effort than their summer-breeding congeners.These findings suggest that winter-breeding species have a phenology matching a winter prey resource on the shelf of the west coast of New Zealand’s South Island. With additional data from literature for little penguin Eudyptula minor and spotted shag Stictocarbo punctatus, this winter-breeding community showed partial overlap of their foraging niche, but an accumulation of small divergences in home ranges, diving behaviour, temporal pattern of foraging, diet and trophic level is likely to explain their coexistence. Hence, winter-breeding can be a favourable phenology for high-level predators, which exploit shelf-slope and inshore waters undergoing winter mixing that insure fish and squids persistence through winter. In addition, winter-breeding also allow the matching of chick-fledging period with the spring (local primary production peak), and before the elevated needs of millions of summer-breeding species back from migration

Повний текст джерелаSeabirds are ecosystem engineers with two major impacts on island ecosystems: they bring large quantities of marine nutrients to the terrestrial environment in the form of guano, carcasses, feathers, eggs, and spilled food, and they disturb the soil surface. Burrowing seabirds can denude the soil surface of all seedlings and leaf litter, plowing them under and loosening the soil. However, seabirds are colonial, and burrows are not even spaced over the surface of an island, producing spatial variability within a single island that might reveal how seabird activities control island ecosystem function.
In this dissertation I review seabird island ecology in general, focusing on how introduced predators have reduced seabird populations, interrupting seabird activities and altering island ecology. I then describe three studies designed to quantify the effects of seabirds on soil and plant properties within individual islands and compare these patterns across islands varying in seabird density, especially where seabirds have declined because of invasive rats (Rattus spp.).
I used geostatistics to quantify the spatial variance in seabird burrows and various soil and plant properties (including soil and leaf N) within six islands of low, intermediate, and high burrow density. I found that burrow density was not a good predictor at within-island scales, and though the variance of some soil properties (pH, soil δ15N, and soil compaction) peaked on intermediate islands as expected, variables reflecting the soil N cycle (net ammonification and net nitrification potential, NH4 + and NO3-) continued to increase in variability on very high-density seabird islands. Ecosystem properties clearly responded to seabirds at different spatial scales, possibly because seabirds deposit guano at different spatial scales than they dig.
Using data within three rat-invaded and three rat-free islands, I used structural equation models to examine seabird influences on N cycling. I found some mechanisms that were constant across islands, such seabird-related decreases in soil water and pH, but other mechanisms differed between invaded and uninvaded islands, suggesting that rats manifest an alternative state for island N cycles, which may or may not be reversible.
Finally, I investigated whether plants can use ammonia (NH3 gas) volatilized from seabird islands, measuring NH3 concentrations across 10 islands and within a single island where I also experimentally manipulated plant N demand. Both rat-invaded and rat-free islands produced meaningful concentrations of NH3 gas, and multiple plant species including Melicytus ramiflorus and Coprosma macrocarpa used it for up to 20% and 30% (respectively) of their total leaf N. Plant N demand modified NH3 uptake, suggesting that plants located not on seabird colonies, but downwind, may benefit the most from this gaseous N source.
I suggest that future studies attempt to estimate thresholds of burrow density at which seabird-controlled ecosystem properties can recover from rat invasion.
