Abstract:
Abstract Frugivorous birds may be able to reduce the cost of processing seeds by discarding seeds, selecting fruits that have a high pulp-to-seed ratio, or by choosing fruit in which seeds are packaged in a way that the frugivore's gut can void them more rapidly. A preference for fruit based on pulp-to-seed ratio or seed composition within a fruit is likely to have important implications for plants and evolution of seed size. We tested whether captive Silvereyes (Zosterops lateralis) discriminate among artificial fruit on the basis of seed presence by presenting birds with artificial fruit with or without a seed. In the first experiment, fruit were translucent so that birds could see which fruit contained a seed. In the second experiment, the visual cue was removed. When Silvereyes were presented with a choice between translucent, artificial fruit with or without a seed, they showed a strong preference for fruit that did not contain a seed. However, when the visual cue to seed presence was removed, preference for seedless fruit was still significant, but markedly reduced. We also tested seed-size preference of Silvereyes in the field in Victoria, Australia. Seeds from a fruit commonly consumed by Silvereyes, fragrant saltbush (Rhagodia parabolica), were recovered from Silvereye faecal samples and their volumes measured. Comparisons were made between seed volumes of fruit consumed by Silvereyes and those within fruit available on the plant. Silvereyes consumed significantly smaller seeds than the mean size available on saltbush plants. When Silvereyes were presented with a cereal-based diet containing artificial seeds (designed to mimic large fruit containing many small seeds), they avoided seed ingestion and were able to consume proportionally more cereal than seeds, even when on a high seed-load diet (30%). Seed dispersal by Silvereyes may be inefficient for plant species with large fruit containing many small seeds, because Silvereyes in this experiment were able to avoid ingesting seeds.

Abstract:
Recent studies in the Northern Hemisphere have shown that songbirds living in noisy urban environments sing at higher frequencies than their rural counterparts. However, several aspects of this phenomenon remain poorly understood. These include the geographical scale over which such patterns occur (most studies have compared local populations), and whether they involve phenotypic plasticity or microevolutionary change. We conducted a field study of silvereye ( Zosterops lateralis ) vocalizations over more than 1 million km 2 of urban and rural south-eastern Australia, and compared possible effects of urban noise on songs (which are learned) and contact calls (which are innate). Across 14 paired urban and rural populations, silvereyes consistently sang both songs and contact calls at higher frequencies in urban environments. Syllable rate (syllables per second) decreased in urban environments, consistent with the hypothesis that reflective structures degrade song and encourage longer intervals between syllables. This comprehensive study is, to our knowledge, the first to demonstrate varied adaptations of urban bird vocalizations over a vast geographical area, and to provide insight into the mechanism responsible for these changes.

Abstract:
This study investigated the potential risks of using 1080 apple bait for possum control on nontarget species Trials were conducted using captive native birds at Orana Park and honeybees (Apis mellifera) at Halswell to determine whether these species would feed on nonpoisonous apple baits Bird species were kaka (Nestor meridionalis) kea (Nestor notabilis) kakariki (Cyanoramphus sp) silvereye (Zosterops lateralis) weka (Gallirallus australis) and kereru (Hemiphaga novaeseelandiae) Kaka kea kakariki and silvereye preferred to feed on apple bait over carrot bait spending 74100 of their feeding time on the apple bait Honeybees were not attracted to the apple bait It is concluded that there could be a greater risk to native birds when apple baits are used for possum control compared to the risk associated with using carrot bait Consequently it is recommended that aerial application of apple should not be undertaken and that apple baits should be used in bait stations only

Abstract:
The physiological condition of a natural population of silvereyes was monitored near Margaret River in Western Australia in each month for a complete year. Plasma samples were analysed for total corticosteroids, glucose, osmolality, urea, sodium, potassium and chloride; blood haematocrit was recorded. Carcasses were processed to yield body weight, total body water, fat content, lean dry-body weight and lean dry weight of the breast muscles. These results showed that in March total corticosteroids were high, haematocrit was low and fat contents were low. In June, fat contents were low and urea levels were high. Although breast muscle weights did not differ significantly between months, lower mean values during June may indicate that the labile protein content is 58% lower than in May. These results indicate that silvereyes are stressed in March and in poor condition in March and June. March and June may be the periods when natural mortality limits the population size, even in years when the March food supply is adequate.

Abstract:
Most of the architectural design problems are basically real-parameter optimization problems. So, any type of evolutionary and swarm algorithms can be used in this field. However, there is a little attention on using optimization methods within the computer aided design (CAD) programs. In this paper, we present Optimus, which is a new optimization tool for grasshopper algorithmic modeling in Rhinoceros CAD software. Optimus implements self-adaptive differential evolution algorithm with ensemble of mutation strategies (jEDE). We made an experiment using standard test problems in the literature and some of the test problems proposed in IEEE CEC 2005. We reported minimum, maximum, average, standard deviations and number of function evaluations of five replications for each function. Experimental results on the benchmark suite showed that Optimus (jEDE) outperforms other optimization tools, namely Galapagos (genetic algorithm), SilverEye (particle swarm optimization), and Opossum (RbfOpt) by finding better results for 19 out of 20 problems. For only one function, Galapagos presented slightly better result than Optimus. Ultimately, we presented an architectural design problem and compared the tools for testing Optimus in the design domain. We reported minimum, maximum, average and number of function evaluations of one replication for each tool. Galapagos and Silvereye presented infeasible results, whereas Optimus and Opossum found feasible solutions. However, Optimus discovered a much better fitness result than Opossum. As a conclusion, we discuss advantages and limitations of Optimus in comparison to other tools. The target audience of this paper is frequent users of parametric design modelling e.g., architects, engineers, designers. The main contribution of this paper is summarized as follows. Optimus showed that near-optimal solutions of architectural design problems can be improved by testing different types of algorithms with respect to no-free lunch theorem. Moreover, Optimus facilitates implementing different type of algorithms due to its modular system.

Abstract:
AbstractSeed packaging is one fruit characteristic that may influence post-ingestional fruit processing in avian frugivores. We tested the response of a facultative frugivore, the Silvereye (Zosterops lateralis), to fruit containing different forms of seed packaging. Wild-caught, captive Silvereyes were presented with artificial fruit containing either one large seed or three small seeds of equivalent total volume, and their consumption rates were recorded over 90 min. In a second experiment, the seed transit times (ingestion to excretion) for similar large-seeded and small-seeded fruit consumed by Silvereyes were recorded. Silvereyes consumed significantly more large-seeded fruit than small-seeded fruit. The transit time of seeds was also significantly shorter for large-seeded (mean = 22 min) than for small-seeded fruit (mean = 29 min). Thus seed packaging had a significant influence on the rate at which fruit were processed. Silvereyes were able to consume more large-seeded than small-seeded fruit because the seeds in large-seeded fruit were defecated faster than those in small-seeded fruit. It is likely that Silvereyes can compensate for the costs of seed ingestion through having a rapid gut passage rate and hence an increased fruit consumption rate. The gut of Silvereyes showed morphological characters intermediate between insectivores and specialist frugivores. The dimensions of the intestine and gizzard were like those of insectivores and the gizzard was substantially larger than those of specialist frugivores. Facultative frugivores appear to have few morphological adaptations to frugivory and we argue that this facilitates plasticity in the diet and the processing of insects when fruit is not available.¿Influencia el Empaquetamiento de Semillas el Consumo de Frutos y el Tiempo de Tránsito en Aves Frugívoras?Resumen. El empaquetamiento de semillas es una característica que puede influenciar el procesamiento de frutos post ingestión en aves frugivoras. Pusimos a prueba la respuesta de un frugívoro facultativo (Zosterops lateralis) a frutos con distintas formas de empaquetamiento de semillas. Individuos de Z. lateralis silvestres fueron capturados y expuestos a frutos artificiales de volumen equivalente con una semilla grande o con tres semillas pequeñas y su tasa de consumo fue registrada durante 90 minutos. En un segundo experimento, se registró el tiempo de tránsito (de ingesta a defecación) de frutos similares con semillas grandes y pequeñas. Z. lateralis consumió una significativamente mayor cantidad de frutos con semillas grandes que de frutos con semillas pequeñas. El tiempo de tránsito de semillas grandes fué significativamente menor (promedio = 22 min) que el de semillas pequeñas (promedio = 29 min). Por lo tanto, el empaquetamiento de semillas tuvo una influencia significativa sobre la tasa a la que los frutos fueron procesados. Z. lateralis fue capaz de consumir más frutos con semillas grandes ya que sus semillas fueron defecadas más rápidamente que las de frutos con semillas pequeñas. Es probable que Z. lateralis pueda compensar el costo de la ingesta de semillas con un paso rápido a través del tracto digestivo lo que se traduce en un aumento en la tasa de consumo de frutos. El tracto digestivo de Z. lateralis muestra caracteres morfológicos intermedios entre los de insectívoros y frugívoros especialistas. Las dimensiones de los intestinos y la molleja son similares a las de insectívoros y la molleja es sustancialmente más grande que la de los frugívoros especialistas. Los frugívoros facultativos parecieran tener pocas adaptaciones morfológicas a la frugivoría. Sugerimos que esto facilita una mayor plasticidad en la dieta y en el procesamiento de insectos cuando existe poca disponibilidad de frutos.

Abstract:
Reported declines of pollinator populations around the world have led to increasing concerns about the consequences for pollination as a critical ecosystem function and service. Pollination could be maintained through compensation if remaining pollinators increase their contribution or if novel species are recruited as pollinators, but empirical evidence of this compensation is so far lacking. Using a natural experiment in New Zealand where endemic vertebrate pollinators still occur on one offshore island reserve despite their local extinction on the adjacent North Island, we investigated whether compensation could maintain pollination in the face of pollinator extinctions. We show that two recently arrived species in New Zealand, the invasive ship rat ( Rattus rattus ) and the recent colonist silvereye ( Zosterops lateralis ; a passerine bird), at least partly maintain pollination for three forest plant species in northern New Zealand, and without this compensation, these plants would be significantly more pollen-limited. This study provides empirical evidence that widespread non-native species can play an important role in maintaining ecosystem functions, a role that needs to be assessed when planning invasive species control or eradication programmes.

Abstract:
Abstract Inferring the evolutionary dynamics at play during the process of speciation by analyzing the genomic landscape of divergence is a major pursuit in population genomics. However, empirical assessments of genomic landscapes under varying evolutionary scenarios that are known a priori are few, thereby limiting our ability to achieve this goal. Here we combine RAD-sequencing and individual-based simulations to evaluate the genomic landscape of divergence in the silvereye (Zosterops lateralis). Using pairwise comparisons that differ in divergence timeframe and the presence or absence of gene flow, we document how genomic patterns accumulate along the speciation continuum. In contrast to previous predictions, our results provide limited support for the idea that divergence accumulates around loci under divergent selection or that genomic islands widen with time. While a small number of genomic islands were found in populations diverging with and without gene flow, in few cases were SNPs putatively under selection tightly associated with genomic islands. The transition from localized to genome-wide levels of divergence was captured using individual-based simulations that considered only neutral processes. Our results challenge the ubiquity of existing verbal models that explain the accumulation of genomic differences across the speciation continuum and instead support the idea that divergence both within and outside of genomic islands is important during the speciation process.

SummaryThe distribution of Tahitian landbirds in the early twentieth century and at presented here together with maps. Three categories may be recognized: (1) species with a declining distribution owing to changes in habitats (Green-backed Heron), (2) stable or increased species, including local and earlier introduced species, and (3) newly introduced species (Zebra Dove, Red-vented Bulbul, Silvereye and Crimson-backed Tanager). Moreover, owing to their low population numbers, two species, the Pacific Pigeon and the Tahiti Monarch, are on the verge of extinction even if their distribution has not changed notably during this century.Les repartitions des oiseaux terrestres reproducteurs de Tahiti, au début et à la fin du 20e siècle, sont présentées sous forme de cartes. Trois catégories d'espèces sont dis-tinguées: (1) espèce dont la répartition est en déclin a la suite des modifications d'habitats (Héron vert), (2) espèces stable ou en légère augmentation, chez qui on trouve des oiseaux locaux et des oiseaux introduits, et enfin (3) les espèces introduites durant le 20e siècle (Tourterelle striée, Bulbul à ventre rouge, Zosterops à poitrine grise et Tangara cramoisi). II apparaît que deux espèces, le Carpophage du Pacifique et le Monarque de Tahiti, sont aujourd'hui très menacées, même si leur répartition n'a pas régressé d'une façon significative.

AbstractTo study the effects domestic cats may have on surrounding wildlife, a complete list was made of 558 items caught in the garden or brought into the house by one cat over 17 years, from 1988 to 2005. The effect on prey populations was assessed by comparing their abundance with the previous 15 years’ population without a cat. On balance, this cat (Cat 1) was clearly beneficial to the native bird species by killing rodents and deterring mustelids. The diet of a second cat (Cat 2) was recorded in the same way from 2006 to 2016. This cat caught half the number of items 148:287, but in the same proportions: house mice (37.8:42.6); ship rats (12.8:12.1); European rabbits (all young) (8.1:6.7); weasels (0.7:0.4); dunnock (12.8:9.2); house sparrow (2.0:3.1); blackbird (2.7:2.5); song thrush (1.4:1.3); European greenfinch (0.7:5.8); chaffinch (0.7:3.3); silvereye (10.1:8.3); New Zealand fantail (2.0:1.0); lizards (8.1:1.7). Despite this, there were significant differences: Cat 2 avoided finches (2:28, P = 0.004), and took a few more lizards (12:5). For both cats, birds apparently formed about a third of their diet: 33.4% and 34.5%, but comparison of the proportion of birds and rodents brought into the house (12:92) and found dead away from the house (49:45) implies that 320 rodent kills may have been missed, being far more difficult to find. As top predators, these cats were clearly beneficial to native birds, and proposed control or elimination may precipitate mesopredator release and a rabbit problem.

Full text
Abstract:
The influence of accessibility on the fruit preferences of frugivorous silvereyes (Zosterops lateralis) was examined in three different contexts: for captive individuals, in a captive group and in a field situation. Individual silvereyes in small cages were presented with identical artificial fruit that differed only in their accessibility from a perch. The birds removed fruit that could be obtained by ‘picking’ rather than by ‘reaching up’ and avoided ‘hanging’ to remove fruit. A second experiment tested the response of silvereyes to fruit accessibility in a large aviary where birds fed in a group. The artificial fruit were presented at a larger and more natural scale on artificial trees. In this experiment, silvereyes again avoided ‘hanging’ to obtain fruit; however, these birds showed no preference for ‘picking’ over ‘reaching up’. Foraging observations of silvereyes were recorded for three different plant species in the field. Silvereyes generally avoided ‘hanging’ to remove fruit, although the foraging method used varied with the species of plant on which the bird was foraging. The foraging method used by avian frugivores to remove fruit is likely to be influenced by plant morphology, as well as the morphology of the bird. The strong preference shown by silvereyes for fruit that are more accessible suggests that when other fruit characteristics are equal, accessibility is important in influencing fruit-removal patterns. However, this may be affected by the context in which the fruit is presented. Properties of the fruiting plant, such as the branching pattern, perch stability and position of the fruit display, are likely to influence fruit preference. These aspects of plant structure should be considered when assessing foraging behaviour and resource use by frugivorous birds.

Full text
Abstract:
There are many secondary metabolites in ripe fruit that are toxic to vertebrate consumers. The most prevalent explanation for their presence in ripe fruit is to protect the fruit against consumers that do not disperse viable seeds. It has been hypothesised that seed dispersers are not deterred by, or can tolerate, the consumption of secondary metabolites in ripe fruit. We tested whether silvereyes (Zosterops lateralis), which are known seed dispersers, were deterred by quebracho (condensed tannins) presented in two different food types. In the first experiment, silvereyes were given artificial fruit containing either 0% or 5% quebracho and their fruit consumption was measured. A second experiment recorded consumption of a cereal-based, long-term maintenance diet containing either 0% or 5% quebracho. Silvereyes did not exhibit a significant preference for artificial fruit that did not contain quebracho: 39.9% of the fruit consumed did contain quebracho. However, silvereyes strongly avoided the cereal diet containing quebracho, consuming, on average, only 0.36 g (0.06 g) of cereal per 5 h compared with 17.3 g (0.23 g) of cereal that did not contain quebracho. We suggest that because the artificial fruit were swallowed whole by silvereyes, the quebracho may not have been detected as easily in the time available as it would have been in the aqueous cereal diet. Consumption of fruit containing secondary metabolites by wild silvereyes is likely to depend on factors such as food availability, nutrient content of the fruit and the degree of diet mixing.

Abstract:
Birds are important consumers and dispersers of the seeds of fleshy fruit and some have been shown to be selective in their choice of fruit. However, our knowledge of how birds respond to a variety of fruit characteristics is poor. Some birds are known to avoid green fruit or consume them less than fruit of other colours. The fruit of many plant species are green when they are unripe and contain low concentrations of sugars and high concentrations of secondary compounds. In this study, captive silvereyes (Zosterops lateralis) were presented with a choice of red, white and green artificial fruit. Half of them were given these fruit with equal sugar concentrations (15%) and the other half were given the choice but with the green fruit having a sugar concentration twice that of the other two colours (30%). Green fruit were not strongly avoided by silvereyes and were actually preferred when they had a higher sugar concentration than the other two fruit types (red and white). Sugar concentration was therefore a more important determinant of fruit choice than colour. Fruit size is also known to affect fruit choice in some bird species. Small fruit are easier to consume than larger fruit, but contain less pulp. To maximise energy gain, birds should consume fruit that are large, but not large enough to incur high handling costs. Silvereyes in this study were presented with a choice between 20 artificial fruit 4 mm in diameter (large fruit) and 20 artificial fruit 2 mm in diameter (small fruit), both of which they are able to consume. In this experiment, silvereyes exhibited a strong preference for large fruit over small fruit. In general, larger fruit contain more pulp and therefore more energy than smaller fruit. However, other fruit traits, such as seed load, are likely to influence fruit choice by silvereyes in the wild and result in a trait hierarchy.

Abstract:
The ability of migratory silvereyes to orient was tested in the geomagnetic field with one eye covered. Silvereyes using only their right eye were able to orient in migratory direction just as well as birds using both eyes. Using only their left eye, however, the birds did not show a significant directional preference. These data indicate that directional information from the magnetic field is mediated almost exclusively by the right eye and processed by the left hemisphere of the brain. Together with corresponding findings from European robins and indications for a similar phenomenon in homing pigeons, they suggest that a strong lateralisation of the magnetic compass is widespread among birds.

Abstract:
Carfentrazone is a broadleaf weed control herbicide that is also used for control of silvery-thread moss (Bryum argenteum) in creeping bentgrass (Agrostis stolonifera) putting greens. Field studies were initiated in June 2006 and May 2007 to evaluate silvery-thread moss control with carfentrazone alone, carfentrazone applied with nitrogen (N) and/or topdressing (TD), N alone, TD alone, and mancozeb plus copper hydroxide. All treatments except for mancozeb plus copper hydroxide and the non-treated control reduced silvery-thread moss populations 16 weeks after initial treatment. Carfentrazone applied alone and carfentrazone followed by N decreased silvery-thread moss populations by 39%. Carfentrazone followed by TD and carfentrazone followed by N + TD decreased silvery-thread moss populations by 73% and 66%, respectively. These data indicate the importance of using cultural practices to control silvery-thread moss on creeping bentgrass putting greens.

Abstract:
AbstractWe propose the following problem. Given an array of vertical mirrors that simultaneously transmit and reflect, and a single incoming ray of light, describe the configuration of all light rays that are generated. We solve the problem here for a certain infinite configuration of mirrors; the solution involves the winning positions (a(n), b(n)) of Wythoff's game.
