The human population and economy have grown exponentially now impacts on climate, ecosystem processes, biodiversity far exceeding those of any other species. Like all organisms, humans are subject to natural laws limited by energy resources. In this article, we use a macro ecological approach integrate perspectives physics, ecology, economics with an analysis extensive global data show how imposes fundamental constraints economic growth development. We demonstrate positive scaling...
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 biological assessment of rivers i.e., their through use aquatic assemblages, integrates the effects multiple-stressors on these systems over time and is essential to evaluate ecosystem condition establish recovery measures. It has been undertaken in many countries since 1990s, but not globally. And where national or multi-national monitoring networks have gathered large amounts data, poor water body classifications necessarily resulted rehabilitation rivers. Thus, here we aimed identify...
Rivers suffer from multiple stressors acting simultaneously on their biota, but the consequences are poorly quantified at global scale. We evaluated biological condition of rivers globally, including largest proportion countries Global South published to date. gathered macroinvertebrate- and fish-based assessments 72,275 37,676 sites, respectively, 64 study regions across six continents 45 nations. Because were based differing methods, different systems consolidated into a 3-class system:...
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,...
Abstract Globally, our knowledge on lake fisheries is still limited despite their importance to food security and livelihoods. Here we show that fish catches can respond either positively or negatively climate land-use changes, by analyzing time-series data (1970–2014) for 31 lakes across five continents. We find effects of a driver (e.g., air temperature) environment could be relatively consistent in directions, but consequential changes lake-environmental factor water result increases...
Inland recreational fisheries, found in lakes, rivers, and other landlocked waters, are important to livelihoods, nutrition, leisure, societal ecosystem services worldwide. Although recreationally-caught fish frequently harvested consumed by fishers, their contribution food nutrition has not been adequately quantified due lack of data, poor monitoring, under-reporting, especially developing countries. Beyond limited global harvest estimates, few have explored species-specific patterns,...
ABSTRACT Describing the geographic range of aquatic species is crucial for biodiversity conservation and management. This study comprehensively assesses commonly used methods constructing ranges estimating their sizes in freshwater environments, focusing on Curimatidae family tropical fishes distributed Central South America. Our main objective was to evaluate different estimation methods, including convex hull polygons, alpha‐shape polygons with a fixed alpha‐value, dynamic expert maps...
Stable isotope analysis allows the study of element cycles in ecosystems and trophic ecology. δ 13 C reflects diversity primary productivity, while 15 N is a good indicator levels organisms. Caves have limited resources due to absence light, reducing chains these ecosystems. These extreme conditions impose strong selection pressures on cave-dwelling organisms, known as troglobites, which exhibit specific adaptations such vision pigment loss, metabolic physiological differences with their...
Rainbow smelt (Osmerus mordax) have invaded many North American lakes, often resulting in the extirpation of native fish populations. Yet, their invasion is incipient and provides rationale for identifying ecosystems likely to be where management prevention efforts should focused. To predict presence absence, we constructed a classification-tree model based on habitat data from 354 lakes range southern Maine. Maximum lake depth, area, Secchi depth (surrogate measure productivity) were most...
Abstract Habitat modifications, non‐native species and other anthropogenic impacts have restructured fish communities in lotic ecosystems of central Mexico. Conservation native fishes requires understanding food web changes resulting from the introduction species, flow alteration human impacts. Using δ 13 C 15 N analysis invertebrates we investigated effects reservoirs on webs Laja river ecosystem (Guanajuato, Mexico). We estimated trophic position (TP), relative niche dispersion at 11...
The condition index (CI) is a tool that has been used to estimate the effect different environmental factors have on oyster meat quality. CI of oysters in five beds Sapelo Island and Doboy Sound (Georgia, United States) were calculated using three methodologies. Values from each site to: (1) compare two sites located relatively large systems (river/sound) small creek test for differences due system size related nutrient availability; (2) determine parasite, pea crab (Pinnotheres spp.), CI;...
This study presents results from a survey of helminth parasites fishes in the Pánuco River basin, states San Luis Potosí, Hidalgo, Querétaro and Guanajuato, all east central Mexico. Seventeen freshwater fish species (n = 1,019) were examined for helminths between May 1997 September 1998. Thirty-one collected: 11 allogenic species, mostly Nearctic origin, 20 autogenic species. Two anthropogenically introduced recorded. The most prevalent widespread taxon was Posthodiplostomum minimum...
Rainbow smelt (Osmerus mordax) are invaders of inland lakes in the Laurentian Great Lakes region North America and have negatively affected native fish populations. Walleye (Sander vitreus) comprise an important fishery throughout could be by rainbow invasions. We test for declines young-of-the-year walleye (YOY-W) density 12 26 known invaded Wisconsin. Invaded showed significantly lower YOY-W densities than uninvaded during period 1985–2004. In 94% (17/18) years, from were those lakes....
The silverside fish tribe Menidiini (Teleostei: Atherinopsidae) consists of four genera, Menidia, Labidesthes, Poblana, and Chirostoma, that are distributed along the Atlantic coast North America, throughout Gulf México, insular United States, Mesa Central México. It has been suggested Menidia should be recognized as a single genus under nominal Menidia. To test this hypothesis, phylogenetic relationships within were assessed using mitochondrially encoded ND2 gene. Monophyly was supported....
Abstract The association of morphological divergence with ecological segregation among closely related species could be considered as a signal divergent selection in speciation processes. Environmental signals such diet can trigger phenotypic evolution, making polymorphic valuable systems for studying the evolution trophic‐related traits. main goal this study was to analyze between differences traits and two sympatric species, Astyanax aeneus A. caballeroi, inhabiting Lake Catemaco, Mexico....
The current distribution and abundance of the 40 species Goodeidae fishes known from Mexico are described, a total 84 Evolutionarily Significant Units (ESUs) is designated within these species. Two four ESUs likely extinct with no captive populations, three eight probably in wild but have at least one population Mexico, United States, or Europe. Of 35 extant species, analyses indicate that nine should be considered as critically endangered, 14 vulnerable, only concern. Twenty-seven...
Abstract The structure and composition of fish communities in rivers central Mexico have been altered as a result water over‐exploitation, habitat fragmentation, introduction exotic species, pollution. However, the specific pattern degree change are poorly documented. Long‐term information from Laja River (Guanajuato, Mexico) Lerma basin was used to explore trends species richness community (species origin, trophic niche, tolerance, preferred habitat) 1960s present both river reservoir...
Abstract Dams create barriers to fish migration and dispersal in drainage basins, the removal of dams is often viewed as a means increasing habitat availability restoring migratory routes several species. However, these can also isolate protect native taxa from aggressive downstream invaders. We examined community composition two years prior after pair low‐head Boulder Creek, Wisconsin, U.S.A. 2003 determine if potential affected resident population brook trout ( Salvelinus fontinalis )....
In a tropical locality of Río La Antigua, Veracruz, Mexico, 11 fish species, represented by 244 individual from six freshwater families living sympatrically and synchronically, were examined for helminth parasites. A total 36 taxa helminths recorded, 24 autogenic 12 allogenic forms, including 6 monogeneans, 14 trematodes, 1 cestode, 15 nematodes. Most recovered 10/11 the component communities we analyzed. The results contribute empirical evidence that host specificity is an important force...
