Species are characterized by physiological, behavioral, and ecological attributes that all subject to varying evolutionary constraints jointly determine species' role function in ecosystems. Attributes such as diet, foraging strata, time, body size, particular, characterize a large portion of the “Eltonian” niches species. Here we present global species‐level compilation these key for 9993 5400 extant bird mammal species derived from literature sources. Global handbooks monographs allowed...
The emergence of complex cultural practices in simple hunter-gatherer groups poses interesting questions on what drives social complexity and causes the disappearance innovations. Here we analyze conditions that underlie artificial mummification Chinchorro culture coastal Atacama Desert northern Chile southern Peru. We provide empirical theoretical evidence appeared during a period increased freshwater availability marine productivity, which caused an increase human population size...
In the absence of long‐term monitoring data, inferences about extinctions species and populations are generally based on past observations presence a particular at specified places times (sightings). Several methods have been developed to estimate probability timing from records such sightings, but they differ in their computational complexity assumptions nature sighting record. Here we use simulations evaluate performance seven proposed upper confidence limit extinction under different...
Identifying the environmental conditions that drive biogeographic structure remains a major challenge of biogeography, evolutionary ecology and increasingly, conservation biology. Here, we use multivariate classification trees to assess northeast Pacific (∼ 26–58°N) rocky intertidal species (406 algae invertebrates) from 102 field sites. Random forest analyses are used importance 29 variables, encompassing broad range potential drivers, predict structure. Analyses repeated for with different...
Abstract Aim Despite the pervasive and well‐documented effects of global warming on species’ ranges in terrestrial taxa systems, effect sea surface has been poorly studied marine systems. Here we analyse changes southern endpoints distribution rocky intertidal species (gastropods chitons) along Chilean coast, trends temperature (SST), using data collected during last half‐century. Location South‐eastern Pacific between 18°20′ S 42°35′ S. Methods Past were obtained for 10 from museum...
We, as Associate Editors (AEs) for the Journal of Biogeography, have serious concerns about widespread shifts by John Wiley & Sons Ltd (Wiley) and other academic publishers to full Open Access (OA), which appears be imminent journals in portfolio (Rieseberg et al., 2023) has been discussed a possibility Biogeography itself. We commend philosophy OA—to make research freely available online, but many that shift OA, article publication is accompanied expensive processing charges (APCs) payable...
Abstract Worldwide climate‐driven shifts in the distribution of species is special concern when it involves habitat‐forming species. In coastal environment, large Laminarian algae—kelps—form key ecosystems that support complex and diverse food webs. Among kelps, Macrocystis pyrifera most widely distributed provides essential ecosystem services. This study aimed to establish main drivers future distributional changes on a global scale use them predict habitat suitability. Using models (SDM),...
Abstract Aim The abundant‐centre hypothesis (ACH) is based on the assumption that physiological constraints limit populations at edges of their distributional range, yet geographical variation performance or life‐history traits has rarely been examined. Here we examine applicability ACH in a marine system by testing whether predictions are reflected large‐scale variations traits. Location Chilean coast (18°–42° S), encompassing more than 2500 km along Pacific South America. Methods Five...
Aim To understand the ecological and historical/evolutionary processes underlying an inverse latitudinal gradient of richness (LGR) using crustacean peracarid species as a model group. Location The Pacific coast South America, along Chilean between 18° S 56° S. Methods LGR was evaluated dataset including 320 marine reported for coasts Chile. Five hypotheses invoking relationship present-day conditions were tested: species–energy, species–area, Rapoport rescue effect, mid-domain geometric...
Aim We evaluate the stability of range limits rocky intertidal limpet, Lottia gigantea, over last c. 140 years, test validity abundant centre hypothesis, and indirectly roles played by recruitment limitation habitat availability in controlling limits. Because this species is size-selectively harvested, our results also allow us to assess conservation implications. Location The Pacific coast North America, from northern California southern Baja (41.74° N–23.37° N), encompassing entire L....
The biogeography of the Peruvian Eastern Pacific coast has been described based on oceanographic parameters and qualitative species occurrence data. This generated disagreement about limits existence different biogeographic units. In this study, distribution rocky-shore macrobenthic communities were recorded over 41 sites along coastline (3.5°S-13.5°S) analyzed together with historic abiotic data in order to quantitatively evaluate zonation rocky intertidal throughout region its relationship...
Symbiosis and coloniality are ecologically important traits for corals of the order Scleractinia. Symbiotic (zooxanthellate) species highly successful in shallow waters tropical subtropical seas most them colonial. On other hand, azooxanthellate present wide distribution ranges expand to deep-sea at more than 6,000 m depth. These mostly solitary, with only few colonial that form extensive deep reefs. Each distinctive group encompasses half biodiversity they not grouped into differentiated...
Abstract While floating near the sea surface plastic debris interacts with a number of external factors, including many different organisms. Seabirds have most extensive documented history interactions plastics, through ingestion, entanglement, and nest construction. In present study, eight seabird species from South Pacific Ocean were used as proxy to determine potential patterns removal marine debris, three hypotheses tested in relation their feeding habits nesting areas. Plastics abiotic...
ABSTRACT The direct carbonate procedure for accelerator mass spectrometry radiocarbon (AMS 14 C) dating of submilligram samples biogenic without graphitization is becoming widely used in a variety studies. We compare the results 153 paired and standard graphite C determinations on single specimens an assortment carbonates. A reduced major axis regression shows strong relationship between percent Modern Carbon (pMC) values (m = 0.996; 95% CI [0.991–1.001]). An analysis differences confidence...
Abstract Aim In this study we evaluate patterns of endemism for benthic polychaete species along the southeastern Pacific coast Chile. Our goals were (1) to describe latitudinal gradients and identify areas high endemism, (2) effect biogeographical limits on patterns, (3) indirectly role played by evolutionary dynamics endemism. Location South‐eastern Chile, ranging from Arica (18° S) Cape Horn (56° S). Methods We used a list 178 endemic, shallow polychaetes Parsimony analysis endemicity...
The study of complex funerary ritual development among hunters and gatherers societies should take into account how people made up for the continuity their social system without support centralized organizations.This research integrates cultural natural factors to explore Chinchorro carried on with way life isolated at geographically restricted perennial river mouths fresh water along Atacama Desert in Pacific coast South America.Within these rather crowded settlings, they created maintained...
Even though Neogene outcrops along the temperate Pacific coast of South America harbor a rich marine vertebrate fossil record, no studies have examined diversification patterns these taxa. Here, we analyze trends based on stratigraphic ranges 86 genera vertebrates, including sharks, rays, chimaeras, mammals, and seabirds. The richness shows hump-shaped trend, with maximum values around late Miocene, driven by large pulse origination during mid-Miocene higher extinction rates Pliocene. Trends...
The Humboldt Current Marine Ecosystem (HCE) is one of the most productive areas in global ocean, but current anthropogenic stressors, particularly overfishing, pose a significant threat to marine biodiversity. Moreover, limited time scale modern assessments may underestimate magnitude human alterations Here we use rich Quaternary fossil record present along HCE coast, encompassing last ca. 500 kyr, build baseline evaluate impact activities on diversity mollusk assemblages. We compiled an...
