Abstract Background Penguins (Sphenisciformes) are a remarkable order of flightless wing-propelled diving seabirds distributed widely across the southern hemisphere. They share volant common ancestor with Procellariiformes close to Cretaceous-Paleogene boundary (66 million years ago) and subsequently lost ability fly but enhanced their capabilities. With ∼20 species among 6 genera, penguins range from tropical Galápagos Islands oceanic temperate forests New Zealand, rocky coastlines...
Abstract Penguins lost the ability to fly more than 60 million years ago, subsequently evolving a hyper-specialized marine body plan. Within framework of genome-scale, fossil-inclusive phylogeny, we identify key geological events that shaped penguin diversification and genomic signatures consistent with widespread refugia/recolonization during major climate oscillations. We further suite genes potentially underpinning adaptations related thermoregulation, oxygenation, diving, vision, diet,...

Intuition is a poor guide for evaluating the effects of human disturbance on wildlife. Using endangered Yellow-eyed penguin, Megadyptes antipodes, as an example, we show that heart rate responses provide objective tool to evaluate stimuli and encourage wider use this simple low-impact approach. penguins are flagship species New Zealand's wildlife tourism; however, unregulated visitor access has recently been associated with reduced breeding success lower first year survival. We measured via...
Abstract Background Energy landscapes provide an approach to the mechanistic basis of spatial ecology and decision-making in animals. This is based on quantification variation energy costs movements through a given environment, as well how these vary time for different animal populations. Organisms diverse fish, mammals, birds will move areas landscape that result minimised maximised gain. Recently, have been used link gain variable foraging breeding success, revealing their potential use...
Climate shifts are key drivers of ecosystem change. Despite the critical importance Antarctica and Southern Ocean for global climate, extent climate-driven ecological change in this region remains controversial. In particular, biological effects changing sea ice conditions poorly understood. We hypothesize that rapid postglacial reductions drove across multiple widespread species. test demographic driven by climate events over recent millennia analyzing population genomic datasets spanning 3...
The use of animal-borne cameras enables scientists to observe behaviours and interactions that have until now, gone unseen or rarely documented. Researchers can now analyse prey preferences predator-prey with a new level detail. New technology allows researchers features before they are captured, adding dimension existing analysis techniques, which primarily relied on examining partially fully digested through stomach flushing. To determine size, the video footage captured needs correction...
Highly pathogenic avian influenza (HPAI) virus subtype H5N1 has never been detected in New Zealand. The potential impact of this on Zealand's wild birds would be catastrophic. To expand our knowledge viruses across Zealand, we sampled aquatic from its outer islands and subantarctic territories. Metatranscriptomic analysis 700 individuals spanning 33 species revealed no detection during the annual 2023-2024 migration. A single H1N9 red knots (Calidris canutus) was noted. This study provides a...
Abstract The link between poor reproductive success and diet was investigated in yellow‐eyed penguins Megadyptes antipodes , by assessing at two localities separated about 30 km: the north coast of Stewart Island where breeding is low (0.38–0.67 chicks per pair recent years), Codfish higher (0.96–1.51 pair), relating this to published data from South localities, average 1.1 pair. Diet composition, meal sizes energetic content meals prey were determined stomach contents, stable isotope...
Free-ranging marine predators rarely search for prey along straight lines because dynamic ocean processes usually require complex strategies. If linear movement patterns occur they are associated with travelling events or migratory behaviour. However, recent fine scale tracking of flying seabirds has revealed straight-line movements while birds followed fishing vessels. Unlike seabirds, penguins not known to target and follow Yet yellow-eyed from New Zealand often exhibit directed searching...
Climate change is a global issue with effects that are difficult to manage at regional scale. Yet more often than not climate factors just some of multiple stressors affecting species on population level. Non-climatic factors—especially those anthropogenic origins—may play equally important roles regard impacts and feasible address. Here we assess the influence trends endangered Yellow-eyed penguin ( Megadyptes antipodes ) over last 30 years, using Bayesian model. Sea surface temperature...
Camera loggers are increasingly used to examine behavioural aspects of free-ranging animals. However, often video deployed with a focus on specific traits utilizing small cameras limited field view, poor light performance and quality. Yet rapid developments in consumer electronics provide new devices much improved visual data allowing wider scope for studies employing this novel methodology. We developed camera logger that records full HD through wide-angle lens, providing high resolution...
Foraging efficiency determines whether animals will be able to raise healthy broods, maintain their own condition, avoid predators and ultimately increase fitness. Using accelerometers GPS loggers, features of the habitat way deal with variable conditions can translated into energetic costs movement, which, in turn, energy landscapes.We investigated landscapes Gentoo Penguins Pygoscelis papua from two colonies at New Island, Falkland/Malvinas Islands.In our study, marine areas used by...
Abstract In the past few years, studies have been carried out to record and analyse consumer behaviour of manual dishwashing. Manual dishwashing in households is performed many ways that influence use resources. Furthermore, knowledge has gained on basis experiments how optimize resources Optimization here means achieving best possible cleaning performance with a minimum input This experimental knowledge, combined experience everyday life, was transferred into Best Practice Tips.

Summary The recent development of miniaturized saltwater immersion geolocators has made it possible to track and record activity even the smallest seabird species over extended periods time. resulting data comprise various time stamps times integrated 10‐min intervals. Generally, such sets are large complex which makes analysis a daunting task, especially in absence dedicated software solutions. We developed Actave.net as freely accessible, web‐based ( http://www.actave.net ) tool for that...
Migratory species often roam vast distances bringing them into contact with diverse conditions and threats that could play significant roles in their population dynamics. This is especially true if long-range travels occur within crucial stages of a species' annual life-cycle. Crested penguins, for example, usually disperse over several hundreds kilometres after completing the energetically demanding breeding season preparation costly moult. A basic understanding crested penguins' pre-moult...
