This is a conference paper presented at the ICLR 2023 "Machine Learning for Remote Sensing" workshop. Protecting and restoring ecological connectivity is essential to climate change adaptation, and necessary if species are to shift their geographic distributions to track their suitable climatic conditions over the coming century. Despite the increasing availability of near real-time and high [...]
Building a Queer- and Trans-Inclusive Microbiology Conference
Published: 2023-05-03
Subjects: Gender Equity in Education, Microbiology
Microbiology conferences can be powerful places to build collaborations and exchange scientific thought, but for queer and transgender (trans) scientists they can also become sources of alienation and isolation. Many conference organizers would like to create welcoming and inclusive events but feel ill-equipped to make this vision a reality, and a historical lack of representation of queer and [...]
Population decline reduces cooperative breeding in a spatially heterogenous population of superb fairy-wrens
Published: 2023-05-03
Subjects: Ecology and Evolutionary Biology, Life Sciences
1. Reproductive performance in birds can be affected by both social environment and small-scale environmental heterogeneity via food abundance, availability of nesting sites, and predation risk. However, to date, the best studies of effects of microhabitat variation on avian populations have been on northern hemisphere passerines using nestboxes, where birds have limited control over nest sites [...]
Acoustic evidence for seasonal migration by a top predator of the deep sea
Published: 2023-04-28
Subjects: Life Sciences
In ecosystems influenced by strong seasonal variation in insolation, the fitness of diverse taxa depends on seasonal movements to track resources along latitudinal or elevational gradients. Deep pelagic ecosystems, where sunlight is extremely limited, represent Earth’s largest habitable space and yet ecosystem phenology and effective animal movement strategies in these systems are little [...]
Morphological and anatomical characterization of extrafloral nectaries of Opuntia streptacantha and Ferocactus recurvus (Cactaceae)
Published: 2023-04-28
Subjects: Life Sciences
Background: The Cactaceae family displays remarkable diversity in the morphology of extrafloral nectaries (EFNs). Despite their taxonomic, ecological, and evolutionary significance, their anatomy and morphology are poorly understood. Questions: How are the morphological and anatomical attributes of extrafloral nectaries in Opuntia streptacantha and Ferocactus recurvus? Studied species: Opuntia [...]
Conservation macrogenetics
Published: 2023-04-27
Subjects: Biodiversity, Ecology and Evolutionary Biology
Genetic diversity is a core aspect of biodiversity that has been underrepresented in global conservation policy but is gaining rapidly increasing recognition. Conservation geneticists have traditionally focused on identifying, managing, and safeguarding the adaptive potential of specific populations or species. However, for almost all species, conservation relevant, population-level genetic data [...]
Bioremediation by Chlorella vulgaris: Potentials for Treatment of Municipal, Agricultural, and Industrial Wastewater Sources
Published: 2023-04-26
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Developing countries such as the Philippines suffer from a lack of policy development and implementation on wastewater treatment and discharge. Chlorella vulgaris is a microscopic green algae that has been employed in other countries for WWT due to its ability to simultaneously reduce pollutants and produce valuable biomass. However, challenges in technology adaptation such as differential [...]
Descriptive inference using large, unrepresentative nonprobability samples: An introduction for ecologists
Published: 2023-04-26
Subjects: Life Sciences
Biodiversity monitoring usually involves drawing inferences about some variable of interest across a defined landscape from observations made at a sample of locations within that landscape. If the variable of interest differs between sampled and non-sampled locations, and no mitigating action is taken, then the sample is unrepresentative and inferences drawn from it will be biased. It is possible [...]
Evidence for ancestral olfactory sensitivity but not discrimination across two living elephant species
Published: 2023-04-24
Subjects: Social and Behavioral Sciences
While African savanna and Asian elephants split between 4.2-9 MYA, they are often regarded as one united group, ‘elephants,’ even in the scientific literature. This is concerning, as while both are keystone species in their respective habitats, each face different environmental pressures and have rarely been compared experimentally. Savanna elephants must locate resources that vary spatially and [...]
Repeated evolution of extreme locomotor performance independent of changes in extended phenotype use in spiders
Published: 2023-04-24
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Biology, Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Entomology, Evolution, Integrative Biology, Life Sciences, Zoology
Many animals utilize self-built structures – so-called extended phenotypes – to enhance body functions, such as thermoregulation, prey capture or defence. Yet, it is unclear whether the evolution of animal constructions supplements or substitutes body functions. Here, using Austral brown spiders, we explored if the evolutionary loss and gain of silken webs as extended prey capture devices [...]
Interspecific behavioural interference and range dynamics: current insights and future directions
Published: 2023-04-24
Subjects: Animal Sciences, Biodiversity, Ecology and Evolutionary Biology, Evolution, Life Sciences, Ornithology, Other Animal Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology, Zoology
Novel biotic interactions in shifting communities play a key role in determining the ability of species’ ranges to track suitable habitat. To date, the impact of biotic interactions on range dynamics have predominantly been studied in the context of interactions between different trophic levels or, to a lesser extent, exploitative competition between species of the same trophic level. Yet, both [...]
Ecology and conservation of an endangered flying squirrel in plantations
Published: 2023-04-24
Subjects: Life Sciences
Flying squirrels have important roles in ecosystems; as a disperser of seeds and spores. However, flying squirrel species which strongly depend on old mature forests are declined in abundance as a result of logging of mature forests. Guidelines for the conservation of flying squirrels have been developed, but it is important to have an accurate and deeply understanding of their ecology in order [...]
Forest management drives evolution of understorey herbs
Published: 2023-04-24
Subjects: Life Sciences
Forest management has a strong impact on the forest structure and subsequently on the biotic and abiotic forest understorey environment. Forest understorey herbs can thus be expected to evolutionary respond to management-induced environmental variation (provided sufficient time for adaptation), but this has been little tested to date. Here we use a common garden, to test for genetically based [...]
