Artificial Roost

Migratory shorebirds are declining in all transequatorial flyways, most rapidly in the East Asian–Australasian Flyway. Population trends for shorebirds have been derived at a flyway and continental scale, but changes at the local scale are less well understood. Here we compare trends in migratory shorebird populations using natural and artificial roost sites within a tropical harbour, examine possible drivers of change, and identify appropriate conservation management responses. Counts of 19 migratory shorebird species from 2010 and 2018 showed that total abundance increased at an average annual rate of 3.3% (95% CI=1.3–5.4%, P=0.001) across five natural roost sites. This was driven largely by increases in great knot, with most other species declining. At an artificial site in an adjacent shorebird area, total abundance increased at an average annual rate of 14.5% (95% CI=10.5–18.6%, P ≤ 0.000), with few species declining. These results suggest that there is a need to include both natural and artificial sites within shorebird conservation and management planning and that trends in different species can be driven by a combination of local and external drivers.

Over the past 40 years, the incidence of skin melanoma in the world has increased approximately 3-fold.To study the current epidemiological situation of skin melanoma in the Russian Federation, data on the absolute, coarse and standardized incidence rates of melanoma (S43) in the male and female populations were analyzed. The specific gravity of the melanoma patients detected actively was analyzed at different stages of the tumor process who died within the first year since the diagnosis was established between 2006–2016.The incidence of skin melanoma in the Russian population is characterized by a constant increase of indexes, the average annual rate of increase in the incidence of the Russian Federation’s population of melanoma is 2 times higher than that of the general oncological morbidity. A higher average annual rate and a general increase in the incidence of SM is recorded in the male population. Only every 4th patient in the RF is detected actively, despite the fact that melanoma is a tumor of visual localization. In general, only one third of patients with skin melanoma (32.8%) are diagnosed in the first stage of the tumor process in the Russian Federation. Over the period from 2006 to 2016 in Russia, the indicators of neglect on skin melanoma significantly decreased by 40.6%, however they remain at an unacceptably high level. The index of the first-year lethality from skin melanoma in Russia for the period from 2006 to 2016 decreased by 26.01%.To improve the index of active detection of patients with SM, especially in the early stages, it is necessary to create a system for interaction of primary contact physicians with the patient (dermatovenerologists, cosmetologists, therapists) with the oncological service, the formation of on-alertness among physicians of all specialties, and among the population.

Abstract Background In sub-Saharan Africa HIV transmission is a major challenge in adolescents, especially among girls and those living in urban settings. Major international efforts have aimed at reducing sexual transmission. This analysis aims to assess the trends in HIV prevalence by gender in adolescents, as well as urban-rural disparities. Methods HIV prevalence data were obtained for 30 countries with a national survey since 2010 and for 23 countries with one survey circa 2005 and a recent survey circa 2015. Countries were grouped into 2% or higher and lower than 2% HIV prevalence among girls 15–19 years in the first survey. Country medians and average annual rates of changes were used to summarize the trends. Data on HIV incidence at ages 15–24 and prevalence at 5–9 and 10–14 years were reviewed from 11 recent national surveys. Trends in urban-rural disparities in HIV prevalence and selected indicators of sexual and HIV testing behaviours were assessed for females and males 15–24 years, using the same surveys. Results HIV prevalence among girls 15–19 years declined in the higher HIV prevalence group from 5.7–2.6% during 2005–2015, corresponding with an average annual rate of reduction of 6.5% per year. Among boys, the median HIV prevalence declined from 2.1–1.2% in the higher prevalence group. Smaller changes were observed in the lower prevalence country group where median HIV prevalence among girls decreased from 0.7–0.4% (average annual rate of reduction 5.9%). Girl – boy differences at 10–14 years were small with a country median HIV of 1.0% and 1.3%, respectively. Urban females and males 15–24 had at least 1.5 times higher HIV prevalence than their rural counterparts, and all experienced similar declines during 2005–2015. Condom use and HIV testing increased among adolescents in both higher and lower prevalence countries, but indicators of sexual activity showed little change over time. Conclusions HIV prevalence declined in almost all countries during the last decade, in both urban and rural settings, for both sexes. The urban-rural gap persisted and HIV transmission to girls, but not boys, is still a major challenge in eastern and southern African countries.

Established Role

Fire is an important natural disturbance process within the Australian landscape, but the complex and hazardous nature of fire creates a conservation management dilemma. For landholders of private conservation lands, management for conservation of biodiversity and risk reduction is complicated. Private conservation landholders in eastern Australia directed far less effort towards fire management than other conservation management actions, despite clearly acknowledging the risk and associated responsibilities of fire management on their lands. Nonetheless, landholders did undertake actions to reduce fuel hazards and prepare for wildfire events on their land. Despite the established role and benefits of fire to many ecosystems in the region, landholder understanding of the ecological role of fire was generally poor. Few landholders were aware of ecologically appropriate fire regimes for the vegetation types on their property, and few undertook fire management actions to achieve ecological outcomes. Site-specific obstacles, lack of fire management knowledge and experience, and legal and containment concerns contributed to the low level of fire management observed. There is a need for property-specific fire management planning across all private conservation lands, to further integrate ecological fire requirements into biodiversity management, and prioritise actions that aim to improve conservation outcomes while safeguarding life and property.

Abstract The flat-headed cat Prionailurus planiceps is one of the rarest small felids, with little known about its distribution, population status or habitat requirements, largely because of the few records of the species. We report here 11 detections of this Endangered species, recorded during 4 years of camera-trap surveys in a peat-swamp forest on the Kampar Peninsula, Riau province, Sumatra. These are the first records of this species on the Kampar Peninsula, in an area of c. 1,300 km2 of peat-swamp forest comprising four adjacent Ecosystem Restoration Concession licences. All records were near water bodies (mean distance 351 m) in lowland peat-swamp forest. These findings add to the existing knowledge of the species' distribution in Sumatra and confirm its presence in these peat-swamp forests. To inform species conservation management planning for the Kampar Peninsula, further research on this species is required.

Background: Over the last decade many programmes have been implemented to improve the health of pregnant women and neonates. This study aims to look at the changes in modes of delivery and perinatal mortality rates in a rural block of Tamil Nadu between 2006 and 2015.Methods: Data on all the births that have occurred in this rural block of Tamil Nadu that has been prospectively collected between 2006 and 2015 was analysed. A longitudinal analysis was done to calculate the primary and overall caesarean section rate and the average annual rate of increase. The perinatal mortality rate was also calculated.Results: The primary LSCS rate has increased from 9.08% in 2005 to 16.1% in 2015. The overall caesarean section rate has increased from 11.7% to 19.2% in the same time with an average annual rate of increase of 5.1%. During this period the perinatal mortality has decreased from 33 per 1000 live births to 17 per 1000 live births.Conclusions: Though the overall caesarean section rate is higher than the 15% prescribed by WHO the rates are lower than the rest of the country and rural Tamil Nadu.

AbstractAmphibian populations world-wide are threatened by declines and extinctions mainly due to habitat loss and fragmentation. Habitat fragmentation threatens the yellow-bellied toad Bombina variegata in the northern and western regions of its distribution where it is strictly protected. We studied the genetic structure and diversity of populations at three geographical scales using microsatellite loci to detect potential threats for population persistence. At the local scale, we sampled four neighbouring localities at 1–2.6 km distance to detect effects of short-term (decades) fragmentation on connectivity. At the regional scale, five additional localities in the mountains of the Westerwald (Rhineland-Palatinate, Germany) were studied at up to 50.1 km distance to analyse genetic diversity and population structure. At the continental scale, we included data from regions in the northern distribution with fragmented populations (Hesse and Lower Saxony, Germany) and more continuous populations in the South (Alsace, France; Geneva, Switzerland; Trentino, Italy) to evaluate variation of genetic diversity. At the local scale, short-term fragmentation caused significant genetic differentiation between breeding assemblages only 1.4 km apart from each other. At the regional scale, we found notable genetic distance among localities. At the continental scale, we identified Alsace, Trentino and Geneva in the South as regions with low genetic structuring and high allelic richness, and the northern remaining regions in Germany as deeply structured with reduced allelic richness. We suggest that reduced genetic diversity and habitat fragmentation in northern regions makes these populations particularly vulnerable to decline. In conclusion, informed conservation management of B. variegata should focus on measures maintaining or improving connectivity among neighbouring populations.

abstract Slippage (also called creep) on the Hayward fault has produced a right-lateral shift of about 0.7 feet in three sets of railroad tracks that were built 55 and 56 years ago. The average annual rate of 0.15 inch per year is about one-third the average rate of slippage on the San Andreas fault, but the rate has been much greater during short intervals. The zone of acute deformation of the tracks is 20 to 80 feet wide; the tracks are underlain by unconsolidated deposits more than 300 feet thick. Surface faulting at this locality in the 1868, and probably in the 1836, earthquake suggests that the processes of fault rupture and fault slippage can alternate at the same locality.

Cat Tien National Park

A case study is given of a conservation management planning exercise underway in Cat Tien National Park and its surrounding areas in southern Vietnam. The importance of reliable information in this process is demonstrated using the Park's mammalian diversity. Opportunities and constraints to engage the local communities in conservation management planning and implementation are reviewed. The spatial element in protected area management planning is stressed; in some areas strict preservation management regimes are needed to conserve critical biodiversity values while in other areas conservation benefits could be gained from engaging local communities in resource management. Pragmatic conservation management planning decisions address identified threats, to be resolved by re-demarcation of boundaries, resettlement of people, and community-based conservation initiatives. These should result in a more viable Park as well as provide more secure livelihood conditions for the people elsewhere. This case study is put in the context of the wider conservation management debate.
