The COVID-19 pandemic has brought biosecurity to the forefront of national security policy. Land use change is a fundamental driver of zoonotic disease outbreaks, yet substantial study is yet required to unravel the mechanisms by which land use-induced spillover operates. Ecological degradation may be the 21st Century’s most overlooked security threat. Within the biosecurity context, we introduce [...]

Ecological restoration should be regarded as a public health service. Unfortunately, the lack of quantitative linkages between environmental and human health has limited recognition of these principle. Advent of COVID-19 pandemic provides the impetus for the further discussion. We propose ecological countermeasures as highly targeted, landscape-based interventions to arrest the drivers of land [...]
Validating morphological condition indices and their relationship with reproductive success in great-tailed grackles
Published: 2020-11-19
Subjects: Animal Sciences, Animal Studies, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Social and Behavioral Sciences
Morphological and physiological variation among individuals has the potential to influence multiple life history characteristics such as dispersal, migration, reproductive success, and survival. Individuals that are in better "condition" can disperse or migrate further or more successfully, have greater reproductive success, and survive longer, particularly in years where environmental conditions [...]
Wolf depredation hotspots in France: Clustering analyses accounting for livestock availability
Published: 2020-11-06
Subjects: Agriculture, Animal Sciences, Ecology and Evolutionary Biology, Life Sciences, Zoology
Depredation hotspots are the main source of conflict between humans and large carnivores. When locating depredation hotspots, previous studies have not adjusted for livestock availability, making it impossible for managers to discriminate hotspots resulting from underlying livestock clustering from those due to other factors such as environmental factors. We studied hotspots of wolf depredation [...]
Reducing land use-induced spillover risk by fostering landscape immunity: policy priorities for conservation practitioners

Anthropogenic land use change is the major driver of zoonotic pathogen spillover from wildlife to humans. In response to the global spread of the SARS-CoV-2 virus (the agent of COVID-19 disease), there have been renewed calls for landscape conservation as a disease preventive measure. While protected areas are a vital conservation tool for wildlands, more than 50% of habitable land is now [...]
Combining social information use and comfort-seeking for nest site selection in a cavity-nesting raptor
Published: 2020-09-30
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Ornithology
When selecting a breeding site, individuals can use social information to reduce the uncertainty regarding habitat quality. In particular, individuals from several bird species tend to reuse nests previously occupied by competitors. Re-occupying nests previously used by conspecifics or heterospecifics could result from exploiting social information by copying competitors’ choice (the ‘social [...]
A methodological roadmap to quantify animal-vectored spatial ecosystem subsidies
Published: 2020-07-28
Subjects: Animal Sciences, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology, Zoology
Ecosystems are open systems connected through spatial flows of energy, matter, and nutrients. Predicting and managing ecosystem interdependence requires a rigorous quantitative understanding of the drivers and vectors that connect ecosystems across spatio-temporal scales. Animals act as such vectors when they transport nutrients across landscapes in the form of excreta, egesta, and their own [...]
Potential effects of habitat fragmentation on wild animal welfare
Published: 2020-06-18
Subjects: Animal Sciences, Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences
The fragmentation of habitat has occurred throughout the history of life on Earth, but has been accelerated and magnified in scale over the past few centuries as a result of human industrial development. Habitat fragmentation affects the welfare of some wild animals directly, through the often violent processes that bring about fragmentation and by reducing the distance between them and the [...]
Desert Locust in India: The 2020 invasion and associated risks
Published: 2020-06-01
Subjects: Agricultural Economics, Agricultural Science, Agriculture, Agronomy and Crop Sciences Life Sciences, Animal Sciences, Entomology, Life Sciences, Plant Sciences, Social and Behavioral Sciences, Urban Studies and Planning, Zoology
Wind direction, often used in forecasting locust migration, indicates a non-zero probability of desert locust invasion in eastern Indian states. Apart from present controlling measures, we are additionally suggesting to be cautious about the eggs of locust as the rainfall associated with Super Cyclone Amphan has created a favorable breeding ground for the gregarious locust. Also reverse migration [...]
Assessing Raspberry Shake and Boom sensors for recording African elephant acoustic vocalizations

Subjects: Animal Sciences, Ecology and Evolutionary Biology, Life Sciences, Other Animal Sciences, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences
In this work we assess the performance of the Raspberry Shake and Boom (RS&B) sensor package for detecting and monitoring African elephants (Loxodonta africana). This is the first documented test of this particular unit for recording animal behaviour; the unit was originally designed for detecting tectonic earthquakes and low frequency (<50 Hz) atmospheric acoustics. During a four day [...]
Physiological condition of amphibians exposed to historical industrial pollution in a Brazilian biodiversity hotspot
Published: 2020-03-06
Subjects: Animal Sciences, Biodiversity, Biology, Life Sciences, Physiology
Industrial pollution is a significant global threat to biodiversity, but its consequences on rainforest ecosystems remains poorly understood. Amphibians are especially susceptible to pollutants released on natural environments due to their aquatic-terrestrial life cycle. Here, we explored the effects of severe historical air, water and soil industrial pollution of Cubatão Industrial Complex (São [...]
Intergroup food transfers in wild golden lion tamarins (Leontopithecus rosalia)
Published: 2020-03-01
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Zoology
Transfers of food between adults are uncommon in primates. Although golden lion tamarins (Leontopithecus rosalia), are unique among primates in the extent of food transfers, reports of food transfers between adults have so far been restricted to captive or reintroduced individuals. Here, I report the first six recorded events of adult-adult food transfers between individuals belonging to [...]
Aerobic scope protection reduces ectotherm growth under warming
Published: 2020-01-23
Subjects: Animal Sciences, Comparative and Evolutionary Physiology, Life Sciences, Physiology, Zoology
Temperature has a dramatic effect on the physiology of ectothermic animals, impacting most of their biology. When temperatures increase above optimal for an animal, their growth gradually decreases. The main mechanism behind this growth rate reduction is unknown. Here, we suggest the ‘aerobic scope protection’ hypothesis as a mechanistic explanation for the reduction in growth. After a meal, [...]
Seasonality, diet, and physiology as a predominant control factors of the moult dynamics in birds – a meta-analysis
Published: 2020-01-09
Subjects: Animal Sciences, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Moult is a process, usually occurring annually, in which birds replace their plumage. It is one of the most crucial life-history traits because it restores the functions of plumage and allows a bird to adapt to environmental conditions or special seasonal needs such as breeding and camouflage during non-breeding season. Consequently, moulting has advantages in terms of future performance. [...]
Assessing biomarkers of ageing as measures of cumulative animal welfare
Published: 2019-12-17
Subjects: Animal Sciences, Life Sciences, Other Animal Sciences
In order to determine which conditions provide the best overall quality of life for nonhuman animals, it is important to be able to measure their cumulative welfare experience. The ideal measure of cumulative welfare would be comprehensive, objectively measurable, and easy to transfer across species; however, existing approaches fall far short of this ideal. Recent academic work has suggested [...]
