Bisphenol A (BPA) is a monomer used in the manufacture of multitude chemical products, including epoxy resins and polycarbonate. The objective this study was to evaluate effects BPA on male sexual development. This study, performed CF-1 mice, limited measurement sex-organ weights, daily sperm production (DSP), epididymal count, testis histopathology offspring female mice exposed low doses (0, 0.2, 2, 20, or 200 microg/kg/day), by deposition mouth gestation days 11-17. Male development...
Abstract Aim Spatially‐explicit trends in species richness and endemism on sandy shores are quantified to assess representation of beach ecosystems existing reserve networks. Also, the relative importance different drivers distributions compared through distribution modelling. Location The South African beaches among best‐studied world, providing sufficient biological data for analyses. There is also a well‐established coastal protected‐area network that putatively provides moderate...
Background: The Vegetation Map of South Africa, Lesotho and Swaziland (National [NVM]) is a fundamental data set that updated periodically. National Biodiversity Assessment (NBA) 2018 process provided an opportunity for more comprehensive revision the NVM better alignment between terrestrial, marine estuarine ecosystem maps.Objectives: aim this study was to update quantify spatial classification changes since 2012, describe rationale sources utilised. We also quantified errors corrected in...
To support sustainable growth of ocean-based economies, many countries are engaging in marine spatial planning (MSP) processes, which require robust decision-support tools. Systematic conservation (SCP) is commonly used decision-making to guide spatially efficient protected area expansion. Here we contend that SCP can also be streamline MSP negotiations by developing a coherent, integrated portfolio sites for multiple sectors depend on biodiversity being maintained good state, as...
Ecosystem services provide substantial benefits to people, but the underlying ecosystems are under unprecedented pressure, compromising service delivery. Therefore, ecosystem need be integrated into conservation and management processes secure their for current future generations. A key first step is a robust method map spatial planning. We aimed develop apply broadly applicable, flexible spatially accurate comprehensive mapping using Ecological Infrastructure, abbreviated PROPSER. evaluated...
Copepods and seawater were collected during spring bloom conditions off southwest Nova Scotia the east coast of Newfoundland, Canada.The copepods starved for 12 or 24 h then fed with screened seawater.High pressure liquid chron~atography (HPLC) was used to measure concentrations chlorophylls a c (and derived phaeopigments), fucoxanthin dladinoxanthin in incubation medium both before after grazing, purified samples faecal pellets grazing.Close 100 % ingested did not survive digestion by...
The arctic copepod Pseudocalanus can be highly aggregated in the first few centimeters under landfast ice during spring concentrations up to 10/(6) per cubic meter. Chlorophyll-derived pigments water, abundance of animals, and their gut pigment index show fluctuations that may tidally related. Short-term grazing experiments performed at -1.7 degrees C, which algae was used as food, yielded feeding rates comparable highest known for genus. Arctic seem feed opportunistically near ice-water...
Zooplankton samples were collected from 0 to 50 m depth at 2 stations in Jones Sound and 1 Baffin Bay August September of 1983.Levels chlorophyll phaeopigment measured several stages Calanus hyperboreus glacialis 4 h intervals, examine diurnal feeding behavior copepods which do not vertically migrate on a daily basis.All examined for each the species showed variations activity.In addition, different always started feed synchronously, although timing onset evening was 3 stations.On occasion...
Coastal ecosystems are highly vulnerable to human-mediated drivers of global change because they located at the land–ocean interface and often host centres urbanisation development. The South African coastline comprises several distinct coastal ecoregions that support a wide range (inshore) ecosystems, including rocky, sandy mixed shores, kelp beds, estuaries seagrass communities. A growing body evidence indicates local air sea temperatures, wind patterns, ocean current speed upwelling...
Identifying key sites of marine biodiversity value and implementing the required practical spatial management measures is critical for safeguarding maintaining essential ecological processes, especially in face accelerating global change expanding ocean economies. Delineating Ecologically or Biologically Significant Marine Areas (EBSAs) has been catalytic progressing toward this aim. However, Benguela Current Large Ecosystem (BCLME; comprising three developing countries: Angola, Namibia,...
Abstract Latitudinal range limits for mangroves on high‐energy, wave‐dominated coasts are controlled by geomorphological features and estuarine dynamics. Mangroves reach a southern global limit along the South African coastline, but distribution is patchy, with stands occurring in only 16% of estuaries region. Yet, persistence forests planted >50 years ago beyond natural suggests that additional could support mangroves. Understanding regional drivers necessary to inform global‐scale...
Summary Scenario planning can be useful to guide decision‐making under uncertainty. While systematic conservation create protected‐area networks for multiple and complex reserve–design scenarios, planners rarely compare different reserve explicitly, or quantify trade‐offs among scenarios. We demonstrate the use of multivariate statistics traditionally applied in community ecology reserves designed using beaches South Africa as an example. Twelve scenarios were run Marxan a hierarchical...
