A key feature of life's diversity is that some species are common but many more rare. Nonetheless, at global scales, we do not know what fraction biodiversity consists rare species. Here, present the largest compilation plant to quantify Earth's large fraction, ~36.5% ~435,000 species, exceedingly Sampling biases and prominent models, such as neutral theory k-niche model, cannot account for observed prevalence rarity. Our results indicate (i) climatically stable regions have harbored hence a...
Human societies have always faced temporal and spatial fluctuations in food availability. The length of time that remains edible nutritious depends on temperature, moisture, other factors affect the growth rates organisms cause spoilage. Some storage techniques, such as drying, salting, smoking, date back to ancient hunter–gatherer early agricultural use relatively low energy inputs. Newer technologies developed since industrial revolution, canning compressed-gas refrigeration, require much...
The discipline of sustainability science has emerged in response to concerns natural and social scientists, policymakers, lay people about whether the Earth can continue support human population growth economic prosperity. Yet, developed largely independently from with little reference key ecological principles that govern life on Earth. A macroecological perspective highlights three should be integral science: 1) physical conservation laws flows energy materials between systems environment,...
The extent to which different kinds of organisms have adapted environmental temperature regimes is central understanding how they respond climate change. Scholander-Irving (S-I) model heat transfer lays the foundation for explaining endothermic birds and mammals maintain their high, relatively constant body temperatures in face wide variation temperature. S-I shows regulated by balancing rates production loss. Both scale with size, suggesting that larger animals should be better cold...
The life histories of animals reflect the allocation metabolic energy to traits that determine fitness and pace living. Here, we extend theories address how demography mass-energy balance constrain biomass survival, growth, reproduction over a cycle one generation. We first present data for diverse kinds showing empirical patterns variation in life-history traits. These are predicted by theory highlights effects 2 fundamental biophysical constraints: on number mortality offspring; growth...
Why some animals have big brains and others do not has intrigued scholars for millennia. Yet, the taxonomic scope of brain size research is limited to a few mammal lineages. Here, we present dataset compiled from literature 1,552 species with representation 28 extant orders. The brain–body allometry across all mammals (Brain) = −1.26 (Body)0.75. This relationship shows strong phylogenetic signal. Thus, conducted additional allometries using median values each order, family, genus ensure...
Abstract We review impacts of climate change, energy scarcity, and economic frameworks on sustainability natural human systems in coastal zones, areas high biodiversity, productivity, population density, activity. More than 50% the global lives within 200 km a coast, mostly tropical developing countries. These developed during stable Holocene conditions. Changes forcings are threatening ecosystems populations. During Holocene, earth warmed became wetter more productive. Climate changes...
Understanding scaling relations of social and environmental attributes urban systems is necessary for effectively managing cities. Urban theory (UST) has assumed that population density scales positively with city size. We present a new global analysis using publicly available database 933 cities from 38 countries. Our results showed (18/38) 47% countries analyzed supported increasing (pop ~ area) exponents ~⅚ as UST predicts. In contrast, 17 (~45%) exhibited scalings statistically...
Rising temperatures associated with climate change are impacting household energy use. Many of today’s industrial-technological-urban humans thermoregulate in the face varying using extra-metabolic use for heating and cooling our indoor microclimates. Previously, as a function temperature over seasons time has been described three-part model thermoregulation, Extra-Metabolic Scholander-Irving (EMSI), where is lowest thermal neutral zone around room increases colder hotter temperatures....
ABSTRACT Species are distributed in predictable ways geographic spaces. The three principal factors that determine distributions of species biotic interactions ( B ), abiotic conditions A and dispersal ability or mobility M ). is expected to be present areas accessible it contain suitable sets for persist. species' probability presence can quantified as a combination responses , via ecological niche modeling (ENM; also frequently referred distribution SDM). This analytical approach has been...
Social interactions among conspecifics are a fundamental and adaptively significant component of the biology numerous species. Such give rise to group living as well many complex forms cooperation conflict that occur within animal groups. Although previous conceptual models have focused on ecological causes fitness consequences variation in social interactions, recent developments endocrinology, neuroscience, molecular genetics offer exciting opportunities develop more integrated research...
Intraspecific variation in social systems is widely recognized across many taxa, and specific models, including polygamy potential, resource defense, dispersion, have been developed to explain the relationship between ecological organization. Although mammals from temperate North America Eurasia provided insights into this relationship, rodents Neotropics South largely ignored. In review we focus on reports documenting intraspecific spacing systems, group size, mating of caviomorphs. This...
Humans, like all organisms, are subject to fundamental biophysical laws. Van Valen predicted that, because of zero-sum dynamics, populations species in a given environment flux the same amount energy on average. Damuth's 'energetic equivalence rule' supported Valen´s conjecture by showing tradeoff between few big animals per area with high individual metabolic rates compared abundant small low requirements. We use scaling theory compare variation densities and human societies other land...
