Cím:Long-term decline in nest survival of a ground-nesting shorebird on a tropical island / Noémie Engel, Grant McDonald, Brett K. Sandercock, Romy Rice, Rocio Moreno, Sara Ratāo, Tamás Székely
Dátum:2023

Megjegyzések:Tropical islands harbour a disproportionally high number of endemic species, which face increasing threats due to habitat loss, disturbance and introduced alien predators. Long-term demographic studies are needed to understand how such threats may impact on population productivity. We report an investigation of a key demographic parameter, nest survival, over a 13-year period in a small ground-nesting shorebird on the island of Maio (Cabo Verde). Similar to many tropical islands, Maio is expected to face increased tourism, disturbance, and potential loss of nesting habitats. We monitored over 700 nests of the largest, year-round resident breeding population of Kentish plover in the Atlantic Ocean archipelago. Our work produced three important findings. First, we show that nest survival differed among the major habitats of the main breeding site, the Salinas do Porto Ingles, because nests in the salt-extraction area had higher daily survival rates DSR = 0.9654 & PLUSMN; 0.0076 SE than nests in grasslands DSR = 0.9557 & PLUSMN; 0.0038 SE. The salt-extraction is a dynamic habitat that is naturally regulated by rainfall and sea water inflow and managed with traditional methods for salt-extraction. Kentish plovers breed on small islets surrounded by salty water where mammalian predators may have restricted access. Second, we found that breeding densities of plovers decreased from 0.11 nests/ha to 0.03 nests/ ha over 13 years. Last, we show that nest survival declined from 0.9784 & PLUSMN; 0.0107 in 2007 to 0.8967 & PLUSMN; 0.0401 in 2019. We suggest that the declining breeding density and nest survival may be driven by a combination of ecological factors including predation by native and introduced species, and by increased human disturbance. To help maintain sustainable levels of nest survival and to ensure long-term persistence of this Kentish plover population, we propose to incorporate traditional Salinas management into direct conservation actions, to reduce human disturbance and manage nest predators to help nest survival on tropical islands.

Cím:Effect of burning of evergreen savin juniper and herbaceous patches on soil : seed banks, chemical and biological properties / Reza Erfanzadeh, Ali Ansari, Mohammad Jafari, Péter Török
Dátum:2023
ISSN:2351-9894
Megjegyzések:The coniferous shrub species Juniperus sabina (savin) is widespread in mountainous regions of Eurasia. The species produces large amounts of fire-prone plant mass in its habitats. The aim of this study was to assess the effect that burning of savin shrubs has on the soil seed bank (SSB), the microbial respiration and the amount of organic matter under its canopy. In each of three sampling areas, four individuals of savin were randomly selected. Under each of these individuals and on adjacent herbaceous control patches, soil samples were taken from 0 to 5 cm and 5-10 cm depths for SSB, biological and chemical analyses. The sampling was repeated after burning the canopy. We found that the immediate effects of burning on the SSB and on the biological and chemical soil parameters were significantly negative. In particular, SSB density, magnitude of microbial respiration and amount of organic matter were significantly decreased after savin canopy burning in 0-5 cm depth, while these changes were less pronounced on the burned herbaceous patches. Hence the restoration of gaps created by burning savin cannot rely on the SSB. Furthermore, alkalization of the soil and decreased soil quality caused by savin burning might hamper the vegetation recovery even in the medium to long run.

Megjegyzések:Facing global climate change is a great challenge for organisms. Numerous species respond to a changing climate by shifting their geographical ranges, adapting to the local climate or finding microrefugia to persist under unfavorable macroclimatic conditions. Orchids are frequently found in roadside verges, and it was demonstrated that roadsides could serve as refugia for them in a changing landscape. We investigated whether roadside slopes, facing different compass directions could serve as microrefugia for orchids, using our database spanning across 18 European countries. Our results showed that the probability of orchid occurrence in north-facing roadside slopes are greater than on south-facing slopes. Further, we found a significant difference in the probability of orchid occurrence in different exposures under unfavorable macroclimatic conditions. In south-facing slopes, the probability of orchid occurrence decreased with increasing annual mean temperature and increasing precipitation seasonality. This suggests that harsh microclimatic environments intensify the negative effects of the macroclimate in south-facing slopes. Moreover, roadside slopes with cooler microclimatic conditions might facilitate the persistence of orchids under a warming and increasingly stochastic climate.

Cím:The role of olive groves in the conservation of Mediterranean orchids / Réka Fekete, Orsolya Vincze, Kristóf Süveges, Henrietta Bak, Tamás Malkócs, Viktor Löki, Renáta Urgyán, Attila Molnár V.
Dátum:2023

Megjegyzések:Olive and olive oil production is one of the main agricultural activities in the Mediterranean region. Besides their economic importance, traditional and organic olive groves were also hypothesized to contribute to biodiversity conservation. For instance, the presence of terrestrial orchids in olive groves has long been known. It is, however, not well understood what ecological or biological traits of olive groves influence the species richness and abundance of these protected flora elements in these secondary habitats. We surveyed 273 olive groves across the mainland of three countries (France, Greece, Italy) and three islands under their administration (Corsica, Lesbos, Sardinia). The surveyed olive groves provided habitat to more than 60,000 orchid individuals belonging to 45 species. Our results indicate that olive groves located on islands had a significantly greater potential for orchid conservation, as they harbored more species and individuals than olive groves on the mainland. Furthermore, orchid presence and species richness was highest in olive groves located on islands with high diversity of pasture weeds or native woody species, while these results also highlight the more traditional use of island groves and a difference in the intensity of maintenance between island and mainland groves. Overall, our study suggests that Mediterranean olive groves contribute significantly to the conservation of diverse terrestrial orchid communities and highlights the importance of traditional management practices in olive groves that allow local biodiversity to flourish.

Cím:A global review on the role of small rodents and lagomorphs (clade Glires) in seed dispersal and plant establishment / Godó Laura, Valkó Orsolya, Borza Sándor, Deák Balázs
Dátum:2022
ISSN:2351-9894
Megjegyzések:Zoochory is an ecologically and evolutionarily important seed dispersal type. The decline and extinction of seed-dispersing large herbivores severely threatens dispersal-driven ecosystem processes in many regions. Hence the relative importance of small rodents and lagomorphs (Glires, Mammalia) as dispersal vectors might increase due to their ubiquity, diversity and abundance. Here we provide a review of rodent- and lagomorph-mediated seed dispersal based on approximately 600 papers found in an extensive literature search. We highlight that small rodents and lagomorphs disperse seeds via various mechanisms. The seldom documented epi- and endozoochory are probably universal in these groups. Due to their small home range, short fur and small body size, these mechanisms generally operate at small scales and mainly for small seeds. Taxon-specific feeding, nesting and behavioural characteristics provide a wide spectrum of other seed dispersal types, such as synzoochory (food caching). The studied taxa generally sup- port seed dispersal within a particular habitat patch, contributing to the persistence of local populations, but in rare cases, long-distance dispersal events might occur. Besides seed dispersal, rodents and lagomorphs can also support plant establishment and provide safe sites for seeds where they can survive stochastic events. Studies reviewed here show a strong bias both in scope and geographical distribution: synzoochorous dispersal of woody plants is known in detail, and most studies were conducted in the same few countries and habitat types. In contrast, other mechanisms such as endozoochory, epizoochory and habitat types like grasslands and anthro- pogenic habitats have rarely been studied. We show examples on ecosystem services and dis- services related to rodent- and lagomorph-mediated seed dispersal as well as the importance of these processes in habitat conservation and restoration.

Cím:Trends in demography, genetics, and social structure of Przewalski's horses in the Hortobagy National Park, Hungary over the last 22 years / Viola Kerekes, István Sándor, Dorina Nagy, Katalin Ozogány, Loránd Göczi, Benjamin Ibler, Lajos Széles, Zoltán Barta
Dátum:2021
ISSN:2351-9894
Megjegyzések:The world population of Przewalski`s horses has recovered from very few survivors, and is still categorized as ?Endangered" in the IUCN Red List of Threatened Species. For this reason, the maintenance of genetically valuable populations is highly important. The 3000 ha Pentezug Reserve in Hortobagy National Park, Hungary, was home to 270 Przewalski`s horses at the end of 2018, approximately 30% of the total European population. In this study, we show the main changes in demographic, genetic, and social characteristics of the population since the establishment of the reserve in 1997. The first years clearly demonstrated that the steppe ecosystem and the wetlands in this area were ideal for the population. We observed that the growing number of individuals affected the total number of harems, but not the average size of the harems. Remarkably, a new phenomenon, herd formation, also appeared. The number of foals per year increased for 17 years (the zenith was in 2014, N ? 60 per year) then started to decrease due to both non-human factors (e.g. delay in female fecundity and decreasing foaling rate) and human intervention (e.g. immunocontraception treatment). The total number of horses peaked in 2017 (N ? 328) and in 2018 decreased (N ? 276) due to decreasing foaling rate, exports, and a population crash. The inbreeding coefficient increased slightly after 2012, while gene diversity stabilized at a relatively high value. Today many individuals from this well-monitored population can be found in Russia and Mongolia. Collectively, understanding of the social structure and mechanisms of population self-control in Przewalski`s horses is improved by our observations. From a population management point of view, our study highlights the importance of human interventions for birth-control and interactions between Przewalski`s horse projects in different countries.

Cím:Exploring ecological knowledge in recreational fishing for conservation purposes : a literature review / Viktor Löki, Jenő Nagy, Zsolt Neményi, Attila Hagyó, András Nagy, Zoltán Vital, Attila Mozsár, Balázs András Lukács
Dátum:2023
ISSN:2351-9894
Megjegyzések:Fishing is a widely popular activity that provides an opportunity for laymen to collect reliable ecological data. It is now recognized that recreational fishers possess valuable ecological knowledge (recreational FEK) that can significantly enhance our understanding of nature, and prioritizing nature conservational tasks. This literature review focuses exclusively on the ecological knowledge of recreational fishers, their perceptions of nature, and the potential for co-production of knowledge through citizen science programs. By conducting literature searches in Google Scholar and Web of Science, we have analysed published articles and evaluated the contributions of recreational anglers and spearfishers to conservation and other ecologically relevant fields. We reviewed a total of 81 studies from five continents, including 22 studies that examined other stakeholder groups, predominantly commercial fishers. Our findings suggest that the mapping of recreational fishers' knowledge presents an opportunity to gain a better understanding of aquatic habitats and wetlands. Their factual observations and perceptions can also provide essential data for species conservation and habitat management, and can help establish citizen science projects for marine and freshwater ecosystems worldwide.

Megjegyzések:Grasslands are ubiquitous globally, and their conservation and restoration are critical to combat both the biodiversity and climate crises. There is increasing interest in implementing effective multifunctional grassland restoration to restore biodiversity concomitant with above- and belowground carbon sequestration, delivery of carbon credits and/or integration with land dedicated to solar panels. Other common multifunctional restoration considerations include improved forage value, erosion control, water management, pollinator services, and wildlife habitat provisioning. In addition, many grasslands are global biodiversity hotspots. Nonetheless, relative to their impact, and as compared to forests, the importance of preservation, conservation, and restoration of grasslands has been widely overlooked due to their subtle physiognomy and underappreciated contributions to human and planetary well-being. Ultimately, the global success of carbon sequestration will depend on more complete and effective grassland ecosystem restoration. In this review, supported by examples from across the Western world, we call for more strenuous and unified development of best practices for grassland restoration in three areas of concern: initial site conditions and site preparation; implementation of restoration measures and management; and social context and sustainability. For each area, we identify the primary challenges to grassland restoration and highlight case studies with proven results to derive successful and generalizable solutions.

Megjegyzések:Although edges are usually considered key areas for biodiversity, previous studies have focused on anthropogenic edges, usually studied edges in relation to forest interiors (disregarding the adjacent non-woody vegetation), and used simple taxonomic indices (without considering functional or phylogenetic aspects). We studied the species composition as well as taxonomic, functional, and phylogenetic diversity of north- and south-facing edges and the two adjacent habitats (forest and grassland) in near-natural forest-grassland mosaics in the Kiskunság Sand Ridge (Hungary) and the Deliblato Sands (Serbia). We found that the species composition of edges was significantly different from that of forests and grasslands, and included species that were rare or absent in habitat interiors. This indicates that the contact of adjacent forest and grassland habitats results in the emergence of a new habitat that deserves scientific attention in its own right. In the Kiskunság, species richness and Shannon diversity were generally higher at edges than in forests or grasslands. In the Deliblato, edges were taxonomically not more diverse than grasslands. Thus, increased taxonomic diversity at edges should not be considered a general phenomenon. In the Kiskunság, forests and edges had higher functional diversity than grasslands, while there were no significant differences among the habitats in the Deliblato. It seems that functional diversity is strongly influenced by canopy openness and the traits of the dominant species. The phylogenetic diversity of woody habitats was higher than that of grasslands both in the Kiskunság and the Deliblato, which probably reflects the different evolutionary age of the habitats.

Megjegyzések:For the effective control of an invasive species, gathering as much information as possible on its ecology, establishment and persistence in the affected communities is of utmost importance. We aimed to review the current distribution and characteristics of Sporobolus cryptandrus (sand dropseed), an invasive C4 grass species of North American origin recently discovered in Hungary. We aimed to provide information on (i) its current distribution paying special attention to its invasion in Eurasia; (ii) the characteristics of the invaded habitats in Central Europe; (iii) seed bank formation and germination characteristics, crucial factors in early establishment; and (iv) the effects of its increasing cover on vegetation composition. Finally, we aimed to (v) point out further research directions that could enable us to understand the invasion success of this potential invasive species. Field surveys uncovered large stands of the species in Central and Eastern Hungary with most of the locations in the former, especially in the Kiskunsag region. The species invaded disturbed stands of dry and open sand grasslands, closed dune slack grasslands and it also penetrates natural open sand grasslands from neighboring disturbed habitats. Increasing cover of Sporobolus cryptandrus was associated with a decline in species richness and abundance of subordinate species both in the vegetation and seed banks, but a low density of Sporobolus cryptandrus can even have a weak positive effect on these characteristics. Viable seeds of Sporobolus were detected from all soil layers (2.5 cm layers measured from the surface to 10 cm in depth), which indicates that the species is able to form a persistent seed bank (1114 to 3077 seeds/m(2) with increasing scores towards higher abundance of the species in vegetation). Germination of Sporobolus cryptandrus was negatively affected by both litter cover and 1 cm deep soil burial. To sum up, Sporobolus cryptandrus can be considered as a transformer invasive species, whose spread forms a high risk for dry sand and steppe grasslands in Eurasia. We can conclude that for the effective suppression of the species it is necessary: (i) to clarify the origin of the detected populations; (ii) to assess its competitive ability including its potential allelopathic effects; (iii) to assess its seed bank formation potential in habitats with different abiotic conditions; and (iv) to assess the possibility of its suppression by natural enemies and management techniques such as mowing or livestock grazing.
