Environmental exposure to active pharmaceutical ingredients (APIs) can have negative effects on the health of ecosystems and humans. While numerous studies monitored APIs in rivers, these employ different analytical methods, measure APIs, ignored many countries world. This makes it difficult quantify scale problem from a global perspective. Furthermore, comparison existing data, generated for studies/regions/continents, is challenging due vast differences between methodologies employed....
Preexploitation shark baselines and the history of human impact on coral reef-associated communities in Caribbean are tpoorly understood. We recovered dermal denticles from mid-Holocene (∼7 ky ago) modern reef sediments Bocas del Toro, Panama, to reconstruct an empirical baseline before major quantify how much community region had shifted this historical reference point. found that denticle accumulation rates, a proxy for abundance, declined by 71% since mid-Holocene. All morphotypes, which...
Many Caribbean coral reefs are heavily degraded, yet their pre-human, natural states often assumed or estimated using space-for-time substitution approaches. Here we use an 11-hectare suite of fossilised mid-Holocene (7.2-5.6 ka) fringing in Panama to define variation hard community structure before human-impact provide context the same today. We collected bulk samples from four trenches dug into fossil reef and surficial 2-10 m depths on five adjacent modern extending over 5 km. Analysis...
Abstract Chondrichthyan fishes are among the most threatened vertebrates on planet because many species have slow life histories that outpaced by intense fishing. The Western Central Atlantic Ocean, which includes Greater Caribbean, is a hotspot of chondrichthyan biodiversity and abundance, but has been characterized extensive shark ray fisheries lack sufficient data for effective management conservation. To inform future research decisions, we analysed patterns in extinction risk,...
Abstract There is a consensus that Caribbean coral reefs are pale shadow of what they once were, yet reef’s pre-human state typically assumed or estimated using space-for-time substitution approaches. These approaches may fail to account for past variation before human impact which could mislead conservation priorities and actions. In this study we use suite fossilised mid-Holocene (7.2-5.6 ka) fringing in Panama define the Historical Range Variation (HRV) community structure human-impact...
Abstract In Panama, shark fisheries were initially developed in the 1980s and progressively increased production 1990s mainly due to high demand for fins meat from international Asian market. Since then, despite exploitation rate (average 3,514 t year –1 ) endangered status of some species, have seldom been studied, official statistics are general or incomplete not suitable development appropriate conservation management strategies. To understand dynamics field surveys conducted between 2007...
La actividad larvicida del aceite esencial de la toronja (Citrus paradisi) fue evaluada contra los mosquitos Aedes aegypti y albopictus, cuales representan vectores potenciales fiebre dengue. CL50 47,3 ppm 85,1 para Ae. respectivamente. El análisis por GC-MS, mostró químicos conocidos como insecticidas podría explicar acción tóxica sobre las larvas evaluados. Esta mayor en comparación con otros aceites cítricos, lo que sugiere mayores instigaciones esta línea manera poder recomendarlo...
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....

Abstract We report the finding of two partial specimens Cryptolepas rhachianecti (Cirripedia, Coronulidae), a coronulid barnacle known only to inhabit skin gray whales ( Eschrichtius robustus ), in Pleistocene-aged sediments from Canoa Basin, Ecuador. While historical range includes North Pacific and Atlantic, our knowledge this is first inferred evidence whale population having resided within South Pacific. describe fossils, use isotopic analysis investigate migration their host whales,...
