Abstract

Human-induced direct mortality affects huge numbers of birds each year, threatening hundreds of species worldwide. Tracking technologies can be an important tool to investigate temporal and spatial patterns of bird mortality as well as their drivers. We compiled 1704 mortality records from tracking studies across the African-Eurasian flyway for 45 species, including raptors, storks, and cranes, covering the period from 2003 to 2021. Our results show a higher frequency of human-induced causes of mortality than natural causes across taxonomic groups, geographical areas, and age classes. Moreover, we found that the frequency of human-induced mortality remained stable over the study period. From the human-induced mortality events with a known cause (n = 637), three main causes were identified: electrocution (40.5 %), illegal killing (21.7 %), and poisoning (16.3 %). Additionally, combined energy infrastructure-related mortality (i.e., electrocution, power line collision, and wind-farm collision) represented 49 % of all human-induced mortality events. Using a random forest model, the main predictors of human-induced mortality were found to be taxonomic group, geographic location (latitude and longitude), and human footprint index value at the location of mortality. Despite conservation efforts, human drivers of bird mortality in the African-Eurasian flyway do not appear to have declined over the last 15 years for the studied group of species. Results suggest that stronger conservation actions to address these threats across the flyway can reduce their impacts on species. In particular, projected future development of energy infrastructure is a representative example where application of planning, operation, and mitigation measures can enhance bird conservation.

Abstract

We examined the regeneration patterns of Pinus sylvestris L. in a natural treed mire in the hemiboreal zone in Latvia. Data on tree stem age and size was collected in 207 fine-scale plots (10 m) and 4 medium-scale plots (400 m). Size structure of living and dead trees was also estimated on transects 180-m and 250-m length and 10-m width. In addition, the vegetation was described in 1-m plots to determine preferred microsites for P. sylvestris establishment. Pinus sylvestris showed continuous regeneration by an inverse J-shaped age and size structure. Pulses of mortality induced by fire were also evident. Regeneration of P. sylvestris was mostly on Sphagnum magellanicam Brid. hummocks free of competition from Ledum palustre L. and graminoids, which were found in small interspersed patches throughout the mire. The spatial pattern of tree cohorts differed, probably due to changing moisture conditions altering seedbed conditions and by fire-induced mortality in specific areas. Recent rapid invasion by Betula pubescens Ehrh. and Picea abies (L.) Karst. in a post-fire period since 1971 is probably associated with drier conditions.222

Abstract

Melnais stārķis ir aizsargājama suga, kuras populācijas lielums Latvijā ir samazinājies no 900 – 1300 pāriem deviņdesmitajos gados līdz 94 – 140 pāriem 2018. gadā. Sugas aizsardzību regulē likumdošana, normatīvie akti un starptautiskās konvencijas, taču ir daudzi būtiski faktori, kam netiek pievērsta pietiekami liela nozīme. Maģistra darbā ir sniegts vispārīgs melnā stārķa aizsardzības nodrošināšanas likumiskais apskats, kā arī mikrolieguma koncepta un dabas aizsardzības vēsturiskā attīstība Latvijā. Rezultātu un diskusijas sadaļā autore iztirzā, kāda ir pašreizējā situācija sugas aizsardzības nodrošināšanā un kādi ir ieteicamie uzlabojumi likumdošanā, sugas izpētē un sugas aizsardzībā. Būtiska darba sastāvdaļa ir teorētiskās un reālās aizsardzības nodrošināšanas apskats. Tas aptver valsts oficiālo datu kvalitāti un putnu dzīvesvietu reālo aizsardzību dabā., The Black Stork is a protected species whose population in Latvia has decreased from 900-1300 pairs in the 1990s to 94-140 pairs in 2018. The protection of the species is regulated by legislation, regulations and international conventions. However, there are many important factors that are not given enough weight. The Master's thesis provide a general legal review of the protection of the black stork, as well as the historical development of the micro-reserve concept and the nature protection in Latvia. Within the results and discussion section, author discusses the current state of conservation of the species and the recommended improvements required within legislation, research of species and the protection of species. An essential part of the work is the overview of the theoretical and realistic protection. This includes the quality of the official country data and the real protection of bird habitats in nature.
