ABSTRACT Aim To examine the species richness, distribution and macroecological patterns of elasmobranch assemblages across a broad latitudinal gradient in Eastern Pacific Ocean (EPO). Location The study area encompasses coast American continent, spanning from 65°N to 60°S, extending coastline approximately 1000 km offshore, encompassing oceanic archipelagos. Taxon Elasmobranchs. Methods Utilising established ranges 190 (comprising 89 sharks 101 rays), we assessed richness spatial these EPO. Subsequently, three were scrutinised: Rapoport's rule, Mid Domain Effect with its association Mean Sea Surface Temperature, correlation between body size distribution. Results analysis along gradients unveiled bimodal pattern, reaching peaks 30° 20°N 10°N 5°S. A decline was observed tropical polar regions. Contrary Rule, Stevens' midpoint methods demonstrated higher geographic range values at lower latitudes, diminishing towards latitudes. Additionally, mid‐domain effect model exhibited robust mean sea surface temperature. Exploring interspecific relationship extent occurrence, it found that 29 out are more susceptible extinction. Main Conclusion Marine elasmobranchs EPO defy conventional deviate rule. Furthermore, our findings indicate both temperature environmental heterogeneity. proportion vulnerable human or stochastic impacts potentially leading extirpation relation their low majority examined provinces.

Wings with an elongated shape or larger surface area are associated increased flight efficiency in a wide range of animals from insects to birds.1,2,3,4 Inter- and intra-specific variation these attributes wing is determined by factors-including foraging ecology, migration, climatic seasonality5,6,7,8-all which may drive latitudinal gradients morphology.9,10 A separate hypothesis predicts that should also follow elevational gradient5,11 because air density declines altitude,12 altering the aerodynamics driving evolution more efficient wings high-elevation species compensate for reduced lift.13,14,15 Although previous analyses have shown tendency longer at higher elevations, least locally,16,17,18,19,20 it difficult rule out alternative explanations since we currently lack global synthesis any taxonomic group. In this study, use phylogenetic models explore effects on metrics morphology linked aerodynamic function 9,982 bird while simultaneously controlling multiple factors ecological species. We found relative elongation (hand-wing index) increase elevation, even when accounting latitude, temperature seasonality, body mass, habitat, aerial lifestyle, altitudinal migration. These results confirm pervasive gradient avian suggest constraints density, perhaps coupled oxygen deficiency, contribute patterns trait flying animals.

Global biodiversity targets focus on landscape and seascape connectivity as a foundational component of conservation, including networks connected protected areas. Recent advances allow the measurement prediction organismal movements at multiple scales. We provide definition that links movement to persistence ecological function. Connectivity science can guide planning for biodiversity, ecosystem services, restoration, climate adaptation. Ongoing change land sea use are closing window opportunity conservation. A coordinated global effort is required implement scientific knowledge monitor, map, protect, restore areas promote maintain well-connected ecosystems in long term.
