Abstract:
Since 2011, tourism to Mexico’s Yucatán Peninsula has been heavily impacted by large masses of sargassum seaweed washing up on the beaches, with the largest seaweed event occurring in 2019. Seaweed deters beach tourism, potentially shifting tourism inland towards other activities such as swimming in cenotes (sinkholes). Our mixed methods study combined data from surveys of visitors to the region, interviews with tourists and tour operators, thematic analysis of newspaper articles, laws and policies and analysis of water samples from a cenote to understand the environmental impact on cenotes of

Abstract:
Abstract Cenote lakes are natural sinkholes or depressions resulting from the collapse of limestone bedrock exposing the groundwater underneath. Thousands of such lakes are particularly encountered on the Yucatan Peninsula (Mexico). These lakes were of great significance for the Maya culture as important religious places and primary source of drink­ing water. They permitted the survival of Mayan communities through dry periods known as “Maya drought”. Most of the cenote lakes are large open water pools measuring tens of meters in diameter. The majority of cenotes are smaller sheliered sites. T

Context Dry forests usually have a marked seasonality in resource availability; as a consequence, wildlife is subjected to drastic changes in food availability during the year. The presence of high-quality sites that provide food during lean periods is crucial in these habitats, especially in human-modified landscapes where resources are limited and scattered. Aims We assessed whether seasonal fluctuations in the availability of fruit resources in two contrasting landscape matrices (continuous tropical semi-deciduous forest and pasture) affect the diet diversity for frugivorous bats, and wheth

The local diving community has termed these speleothems as Hells Bells because of their shape and appearance in a dark environment in ∼ 28–38 m water depth above a sulfidic halocline. It was also suggested that Hells Bells form under water, yet the mystery of their formation remained unresolved.

The vegetation evolution on the modern territory of the Ulyanovsk City and its surroundings, beginning from the late glacial period, can be presented as follows. 11,000– 10,300 years ago: a “tundra-steppe” with wormwood-mazy, horsetail, fern, shrubbygreen-green communities. 10,300–9,500 years ago: wormwood-haze-cenotic cenoses, isolated islets of sparse pine forests. 9,500–8,500 years ago: sagebrush-cerebral, cereal steppes and pine forests. 8,500–8,000 years ago: turf-grass, grass-meadow-grass meadow steppes and pine forests. 8,000–6,000 years ago: forbred-cereal, less often turfgrass meadow

Field experiments (2001–2005) were carried out to create optimal schemes for sowing mixtures of perennial grasses in the forest-steppe of Western Siberia. Objects of research were Krasnoobsky oats, Eastern galega Gorno-Altayskaya 87, awnless brome Antey. The soil of the plots was medium thick, medium loamy leached chernozem. The experiment was carried out in two layouts spread in time and in space. Grasses were sown under the cover of Krasnoobsky oats. Awnless brome was sown across galega in the first ten days of May. Seeding rate of awnless brome was 3.0; 4.5 and 6.0 million germinating seeds

Caridean shrimps are one of the most conspicuous faunal components of the Indo-West Pacific anchialine fauna (Maciolek, 1983). To date, 11 anchialine species distributed in 10 genera and 5 families have been recorded in Indo-Pacific waters, with related species occurring in Atlantic waters, notably in Mexican cenotes and caves in the Bahamas.

The need to study the current state of cenotic populations of rare plant species in nature is not in doubt for the conservation of floristic and phytocenotic diversity at the regional and world levels. The purpose of our study is to study the current state of the cenotic populations of Rare in the Middle Volga basin Hedysarum grandiflorum Pall. To characterize the ontogenetic structure of the cenopopulations, generally accepted demographic indicators were used: the recovery index (the ratio of growth to the generative fraction is calculated), the replacement index (the ratio of growth and th

Entre estas segundas, las depresiones en forma de cenotes, dolinas, uvalas y poljes, han sido objeto de numerosos estudios, al tratarse de zonas de importancia tanto hidrogeol

The aim of this study is to determine whether or not there is a relationship between peat deposit thickness, phytocenosis composition and ecological parameters of plant habitats, using the example of the Beloe Bog located in the Sylvensko-Irenskaya lowland in the south-east of Perm Krai. Measure ments of the depth of the peat deposit were carried out using a peat probe, followed by the dete
