Diversity, Distribution and Relative Abundance of Avian Fauna of Nansebo Forest, Southern Oromia, Ethiopia

Birds are one of the components of biodiversity. Avian community studies are effective tools for monitoring a forest ecosystem. The status of birds in the present study areas is very little known. Therefore, the objective of the study was to assess species composition and relative abundance of birds at Nansebo forest in southern Ethiopia. To this end, a stratified random sampling technique was employed. Accordingly, to collect data for the study, the whole habitat of the study area was divided into dominant vegetation types. Accordingly, Moist Afromontane forest and modified habitat were identified in Nansebo forest. A line transects count aided by binocular was employed to investigate avian species diversity and relative abundance. Accordingly, 20 transect lines of 1km with a width of 0.25km or less was used to cover 27.75% of the area in Nansebo forest. Quantitative Biodiversity indices such as H’,E ,γ and α to measure species richness were used to calculate the bird species diversity and two way- ANOVA was used to test for significant variation in species richness and abundance per season among habitats. A total of 105 bird species consisting of 1endemic, 8 near endemics, 1 globally threatened and 9 Palearctic migrants were recorded in Nansebo forest. Species richness and abundance varied between the three habitats in Nansebo forest. There was significant difference in species richness among habitats in Nansebo forest (F1, 18=94.657 P=0.000) at 0.001 significance level. In Nansebo forest the highest Shannon-Wiener diversity index (H’ = 4.17) was recorded from the modified habitat. It can be concluded that the area has high species diversity including endemics and endangered species. It can also be good potential for bird watching tourism that can integrate economic gain with biodiversity conservation. Hence, urgent conservation measures and further detail research is recommended to conserve the bird species.

Rainy season dietary ecology of avian species in semi-refuge habitats in Kano, Nigeria

Birds are important natural field components, and critical to most ecosystems by supporting seeds dispersal, plant pollination and pest control amongst other functions. Data on avian diversity and feeding behavior could be used to enhance habitats and help initiate conservation strategies. Thus, to characterize the diet of local avian fauna, we selected four semi-refuge sites around Kano metropolis, where we established 22 line transects, each 900m long, spaced 150m apart. During May to October, 2017 each site was visited once a month, adding up to 132 transect-visits. Daily surveillance starts between the local hours of 6:30am to 10:30am. We also transect-surveyed tree vegetation for evaluation of the avian habitats. We recorded a total of 22 bird species belonging to 15 families, with ploceidae as the dominant, and the Laughing dove, Streptopelia senegalensis (Family: Columbidae), being the most dominant species. Over 40% of the bird species fed on insects, other arthropods and earthworms; followed in proportion by seed eaters; while only 3.7% were nectar feeders. Goodness of fit test on observed versus expected dietary item frequencies was significant (Chi-Sq=31.49; P=0.000), indicating field cafeteria habits were not random, but selective or, probably even evolutionary. The manner of food search varied amongst the species, with the Yellow-billed oxpecker, Buphagus africanus and Cattle egret, Egretta alba, expending the most continuous foraging time of 30 to 60 minutes. However, some species, e.g., Senegal coucal, Centropus senegalensis, mainly adopted the pick-and-move strategy. The Shanon- Wiener indices of diversity, H, by site, for birds was fair to moderate (1.24 to 2.53) and paralleled those for the trees. In the light of dearth of avian ecological data from the Kano region, we invite motivated ornithologists, bird enthusiasts and public agencies for research into avian movement patterns, and conservation measures that, we believe, must include habitat protection.

Avian Biodiversity of Newly Established Bunjosa Game Reserve, District Poonch, Azad Jammu and Kashmir, Pakistan: Implications for Conservation

Bunjosa game reserve lies in district Poonch of Azad Jammu and Kashmir, Pakistan. This game reserve is newly established so, avian fauna of this area was unexplored yet, so the present study was undertaken to determine the avian biodiversity, residential status and ecological threats. The findings of the bird’s surveys undertaken from October 2015 to November 2016. A total of n 3137 birds belonging to 108 species, 25 families and 11 orders were identified with highest numbers in summer (n1148) and lowest in winter (n415). The seasonal Shannon Wiener diversity index was highest in summer (4.3), followed by autumn (3.99), winter (3.64) and spring (3.58), likewise the family wise diversity index was maximum for family Corvidae (0.26) and minimum for Remizidae, Phasianidae and Alcedinidae (0.006) respectively. The research findings revealed that habitat fragmentation and clearance through extensive deforestation, forest fires, livestock grazing, and collection of fire woods are recorded as the major threats to the avifauna. Development of conservation and management plan will be helpful in protecting the avian biodiversity and ecosystem of the game reserve.

Living on the Edge: Current Status of Rare Sulu Endemic Avifauna

The Sulu Archipelago, consisting of hundreds of islands, harbors unique and distinct endemic avian fauna. Due to the relatively small size of the islands and the rapid deforestation, many of these species are in danger of extinction. Some of the endemic bird species in the Sulu Archipelago have not been observed in the wild for decades and may already have gone extinct without being noticed. This study uses available information to describe the current status of endemic bird species in the area. Most of the information were gathered from anecdotal reports of birdwatchers who visited the area since very few scientific surveys have been done there. All of the Sulu endemic bird species are forest dependent and categorized as threatened on the IUCN Red List. The Sulu Bleeding-heart Gallicolumba menagei has not been recorded for over a century. The Sulu Hornbill Anthrococeros montani may have no more than 20 pairs left in the wild and not much more is known of the Sulu Hawk-Owl Ninox reyi apart from its name and call. The rapidly disappearing forests, combined with hunting and mining, make the Sulu Archipelago arguably one of the highest priority sites for conservation in the country. The Sulu Archipelago is not only located at the geographical edge of the Philippines, but it is also where unique species are on the edge of extinction. Immediate in situ conservation and comprehensive surveys of the avifaunal diversity in the Sulu Archipelago are urgently needed.

Avian Diversity in Mizoram University Campus, Aizawl, Mizoram

We conducted an avian survey to assess the avian diversity of Mizoram University campus, Aizawl for a period of 24 months. During the study a total of 3,555 no of individuals of 189 species of birds belonging to 43 families were recorded. The family Muscicapidae represented the highest species composition with 28 species followed by family Timaliidae and of MZU campus and its adjacent area, 31 (16.4%) species are winter visitors, 15 (7.9%) species are summer visitor, and two species namely, Hooded pitta (Pitta sordid) and Forest wagtail (Dendronanthus indicus) are passer migrants. The variation calculated was 3.286 and species evenness index was 0.62. The detailed of avian fauna of campus recoded and the need of conservation actions are discussed in length.

Avian diversity is among the key components of the earth’s biodiversity. This study was conducted in Choke Mountains from January to April, 2018 to identify the diversity, relative abundance and distribution of avian fauna. Data were collected in three different habitats (natural forest, grazing and protected areas). The sampling areas were selected using stratified random sampling technique. Point count (for forest site) and line transect methods (for grazing and protected habitats) were employed to collect data. Shannon-Weaver diversity index (H`), Encounter Rate, Richness index (RI), Evenness Index (E) and Simpson’s similarity index (SI) were used for data analysis. A total of 55 bird species belonging to 11 orders and 27 families were identified during the study period. Wattled Ibis (Bostrychia carunculata), Slender billed starling (Onychognathus tenuirostris), Alpine chat (Pinarochroa sordida), Waller’s starling (Onychognathus walleri) and White collared pigeon (Columba albitorques) were the most abundant species in the study area. Relatively higher diversity of bird species was observed in the natural forest habitat (H’ = 2.93) and the lower species diversity was observed in the protected area (H’ = 2.56). The evenness diversity index (E) indicated the highest evenness distribution was registered in the protected area (E = 0.89) and relatively, the lowest evenness was in grazing area (E = 0.87).  The highest species richness was registered in natural forest habitat (4.40) followed by Grazing (3.36) and protected habitats (2.57). Grazing and protected areas have higher similarity index (0.40) and the lower similarity index was observed between natural forest and grazing areas (0.20). Agricultural expansion, overgrazing of livestock contributed to the deterioration in the diversity and abundance of birds of the study area. Thus, serious action is needed to conserve the biological diversity in Choke Mountains.   Key words: Abundance, birds, Choke Mountains, distribution.

Avian fauna of Amboli Ghat, Sindhudurg District, Maharashtra State, India

The present report puts forth a systematic checklist of bird species observed at Amboli Ghat in Maharashtra from 2009 to 2012, along with information on their status. A total of 208 species were recorded, which is around 15% of bird species of the Indian subcontinent. A family-wise analysis showed that the families Accipitridae and Muscicapidae (14 species each) followed by Ardeidae dominated the avifauna of the region. The study also revealed that the area consisted of 11 species of birds that are classified under Near Threatened category and two under Vulnerable category of IUCN. This study highlights the urgent need to conserve the biodiversity-rich area of Amboli Ghat with long-term plans.

Molecular phylogeny and novel host associations of avian chewing lice (Insecta: Phthiraptera) from South Africa

AbstractCompared with Europe and the Americas, the ectoparasites of African birds are poorly understood, despite the avian fauna being relatively well known. Notably, previous studies documenting the host associations and genetic diversity of parasitic chewing lice of southern African birds have been limited in geographic and taxonomic scope. Recent field expeditions exploring the avian diversity in South Africa facilitated an opportunity to obtain louse specimens from a taxonomically diverse host assemblage. This study is the first to investigate avian louse host associations and diversity across a large portion of South Africa encompassing several distinct habitat types, while incorporating molecular genetic data (from portions of the mitochondrial COI and nuclear EF‐1α genes) for ectoparasite phylogenetic analyses. From 1105 South African bird individuals and 170 species examined for lice, a total of 105 new louse–host associations were observed. Morphological and genetic examination of lice with these new host associations reveals a maximum of 66 louse species new to science. Results of this study support the observation that examining museum specimens is a useful way to investigate louse diversity and host associations.

Contribution of Russian zoologists to the collecting and first descriptions of the World avian fauna

A brief overview is given of the formation of museum collections of birds in Russia, collected as a result of academic expeditions around the world and across Russia. The imperishable value of zoological collections, concentrated in zoological museums and institutes, is underlined. The results of expeditions are described in chronology, beginning with 18th century (they were conducted under the auspices of the Russian Academy of Sciences and the Imperial Russian Geographical Society): the First Siberian expedition (D.G. Messershmidt), the First Kamchatka and the Great Northern expeditions (V.I. Bering, А.I. Chirikov, G.F. Müller, G.V. Stöller, I.G. Gmelin, S.P. Krasheninnikov), Great academic expeditions across Russia (P.S. Pallas, S.G. Gmelin, I.A. Güldenstädt, I.I. Lepyokhin, I.P. Falk, I.G. Georgi), round-the-world sea expeditions (I.F. Kruzenshtern and Yu.F. Lisyansky, F.F. Bellingshausen and M.P. Lazarev, F.G. Kittlitz and A.K. Mertens), as well as expeditions to Brazil (G. I. Langsdorf and E.P. Menetries) and expedition of I.G. Voznesensky in Russian America, the Commanders and Kamchatka. Reference is made to the importance of zoological expeditions of K.F. von Baer, A.F. Middendorf, G.I. Radde, N.A. Severtsov, M.N. Bogdanov, G.E. and M.E. Grumm-Grzhimailo. Particular attention is paid to the great Asian campaigns to Central Asia in the late XIX – early XX century of NM. Przevalsky, V.I. Roborovsky, P.K. Kozlov, G.N. Potanin, M.V. Pevtsov, B.L. Grombchevsky, M.A. Pyltsov and N.A. Zarudny. The contribution of the ornithologists of Russia M.N.Bogdanov, M.M. Berezovsky, M.A. Menzbir, V.L. Bianchi, F.D. Pleske, V.I. Dybowski, V.A. Godlewski, M.I. Jankowski, V.K. Taczanowski, P.P. Sushkin and S.A. Buturlin to the bird systematics at the end of the 19th century and the beginning of XX century is described. In conclusion, it is said about the unique value of zoological collections for the study of taxonomy and phylogeny, including on the basis of molecular genetic studies.

Present-Day Assemblage of Birds and Mammals in the Islands of Four Mountains, Eastern Aleutians, Alaska

AbstractWe compiled present-day observations and survey data of the avian and mammal fauna in the Islands of Four Mountains, Alaska, which primarily consist of marine-adapted species, to provide insight into the prehistoric fauna found in the archaeological record. We documented 63 bird species, mainly seabirds (67%). The majority (71%) of the estimated number of breeding birds are ledge nesters, predominately murres, and most (68%) spend the majority of their lives in the offshore environment. We lack good estimates for burrow and crevice nesters, which were impacted by and are still recovering from a period of arctic fox farming in the twentieth century. Marine mammals, predominately Steller sea lion, harbor seal, and sea otter, primarily use accessible land as haul-outs and are found in low numbers compared with the rest of the Aleutians. Red fox, the only land mammal, presently only reside on Chuginadak Island. While the present-day fauna is similar to the fauna recorded in the archaeological record, we found no indication of nesting by ancient murrelets and northern fulmars in the Island of Four Mountains, whereas both species were present in midden sites on Carlisle and Chuginadak Islands, with the possibility of prehistoric breeding colonies on Carlisle Island.

Present status and diversity of avian fauna in Purbasthali bird sanctuary, West Bengal, India

Birds play a crucial role in many food webs of aquatic ecosystem and the birds are known as good ‘bio-indicators’ as they are very sensitive to minor environmental changes. The present study was carried out in Purbasthali bird sanctuary of West Bengal (India) and its surroundings from January 2016 to December 2016 to explore the current status and diversity of avian fauna. The point count and line transect methods were implemented in bird counting. A total of 86 species of birds belonging to 31 families were recorded from the study area. Anatidae and Ardeidae were the dominant families with highest relative diversity. Residential status, IUCN Red list status and Relative abundance of bird species were also considered. Different diversity indices were also calculated. Purbasthali bird sanctuary supports a huge amount of bird diversity. So continuous monitoring of avian fauna and health condition of the ecosystem by local or state levels on taking integrated management programs will helpful to maintain a sustainable development of the habitat.

What do insects, anurans, birds, and mammals have to say about soundscape indices in a tropical savanna

The application of acoustic indices is incipient and still needs validation before it can reliably characterize soundscapes and monitor rapidly disappearing hot-spot areas as the Brazilian tropical savanna (Cerrado). Here we investigate which of six acoustic indices better correlate with the 24 h zoophony richness of insects, anurans, birds, and mammals. We sampled one minute every 30 minutes for seven days on three sites in Serra da Canastra National Park (Minas Gerais state, Brazil) and extracted the sonotype richness and six indices based on recordings with a bandwidth of up to 48 kHz. The Acoustic Diversity, Evenness, Entropy, and Normalized Difference Soundscape indices followed the temporal trends of the sonotype richness of insects and anurans. The Acoustic Complexity (ACI) and Bioacoustic (BIO) indices did not correlated with sonotype richness. ACI and BIO were influenced by sonic abundance and geophony. We emphasize the need to include insects and anurans on soundscape and acoustic ecology analyses and to avoid bias on avian fauna alone. We also suggest that future studies explore measures of sonic abundance and acoustic niche occupation of sonotypes to complement measures of zoophony richness and better understand what each faunal group is telling us about indices.

Assessment of dose-dependent reproductive toxicity of diclofenac sodium in male rats

Diclofenac sodium is widely used in the non-steroidal anti-inflammatory drug in the treatment of pain and inflammation. It is also particularly associated with its adverse effects on avian fauna and linked to environmental issues. The present study was aimed to assess the dose-dependent toxicity of diclofenac sodium on a male reproductive system of rats. Four groups of healthy adult fertile male rats were administered with saline (control) or 0.25 mg/kg, 0.50 mg/kg and 1.0 mg/kg of diclofenac sodium, respectively for 30 days. Alterations in body and organ weight, sperm and testicular cell population dynamics, serum biochemistry, histopathology, and hematology were investigated as per aimed objectives. Diclofenac sodium treatment significantly (p ≤ 0.001) reduced weights of testis, epididymis, ventral prostate and seminal vesicle. Sperm count, sperm density (in epididymis and testis), sperm motility and testicular cell population dynamics were lowered in a dose-dependent manner. Administration of diclofenac exhibited varying degrees of degeneration testis, abnormal histo-architectures, and shrinkages in seminiferous tubules, particularly in higher doses. Diclofenac sodium treatments also altered hepatic and renal function parameters significantly. In conclusion, it may claim that diclofenac sodium treatment altered reproductive metabolic status, androgenic activities and histo-architecture of the testis of male rats and induced hepatotoxicity and renal toxicity.

Species diversity of dry season avian fauna in Kano, Nigeria

The avian fauna in Nigeria and the rest of West Africa is fairly rich, especially during the rainy season when most of the birds are breeding. However, the frequency of species encounter in the field changes as the dry season progresses. The present study examined the diversity of birds during the three dry months following the rains, i.e., November 2016- January 2017, using point count protocol in four partially protected sites, namely, Bayero University Old Campus, Bayero University Kano New Campus, Audu Bako Zoological Garden and Aminu Kano Teaching Hospital. Checklist records show that 42 individual species belonged to 23 families. Most of these species were common to three of the four study sites, and a few, such as Squacco Heron, Ardeola ralloides, were encountered only at Kano Zoo, a small patch of wetland that contrasts with the other drier sites. The Shannon Diversity Index was highest at the Zoological garden site, 2.76. The Piapiac, Ptilostomis afer was peculiar to Aminu Kano Teaching Hospital. Regression analysis showed no influence of months on the frequency of birds seen. However, the Zoological garden in particular, had significant effect on frequencies of birds (P<0.05).Keywords: Avian, Birds, Diversity, Kano, Nigeria

In order to better understand the history and recent trends of urban ornithological research in China, we conducted a systematic review. We used the key words of "urban" and "birds" to search for scientific articles published during 1950-2015 in the "China National Knowledge Infrastructure" database and retrieved 128 articles. Based on our review, we summarized the history and recent trends in publication, main research topics and major findings in urban ornithology studies. The urban ornithology publications increased from an annual average of 0.7 ariticle during 1981-1990 to 11.6 articles during 2011-2015. The research areas include 57 cities located in 29 provinces. The topic of urban ornithology studies includes research of urban avian community structure and distribution, effect of environment factors on urban birds, and practices of urban avian conservation. Major findings include:(1) the urban-rural gradient and different habitat groups would affect avian community structure;(2) environmental factors at different scales had a variety of effects on distribution, breeding, feeding, and physiological conditions of urban birds; and(3) habitat conservation in urban areas and bird attracting measurements, such as setting feeders, contributed to urban avian conservation. However, limited by resources long-term study on urban avian is rare. In addition, very few of studies examined the ecosystem services provided by avian fauna in the urban context. In the future, we suggest researchers pay more attention to(1) the ecological effect of the bird attracting measures,(2)the value of natural experience and environmental education brought by the urban avian fauna, and work with birdwatchers to design long-term urban avian researches. 参考文献 相似文献 引证文献

In Liangshui Reserve, we collected 10,736 capture dates and 14726 effective photographs, including 514 independent mammal photos and 107 independent avian photos. The mammalian fauna identified belonged to four orders, seven families and 11 species, and the avian fauna belonged to four orders, eight families, and 11 species. In Fenglin Reserve, we collected 7460 capture dates and 13677 effective photos, including 638 independent mammal photos and 166 independent avian photos. The mammalian fauna identified belonged to three orders, six families, and nine species and the avian fauna belonged to four orders, 10 families, and 16 species. The number of avian and mammalian fauna monitored accounted for 70%-78% of the total number of species in Liangshui Reserve, whereas that in Fenglin Reserve accounted for 80%-89%. A larger number of avian and mammalian fauna were monitored in Liangshui Reserve and Fenglin Reserve, respectively. Sciurus vulgaris and Eutamias sibiricus possessed the highest Relative abundance index(RAI)among the mammals, followed by Capreolus capreolu; among the avians, Sitta europaea, and Turdus pallidus possessed the highest RAI. The biodiversity index revealed no significant difference in diversity between avian and mammalian fauna. In addition, the mammal community similarity index (Cs) was 0.621, suggesting that avian and mammalian fauna of Liangshui Reserve were largely similar to those in Fenglin Reserve. The present survey suggests that we lack data on nocturnal small rodents among mammals, and most of the avian fauna monitored mainly live ower the forest. 参考文献 相似文献 引证文献

Fresh Water Fish Fauna of Govind Sagar Reservoir Bundelkhand Region, District Lalitpur UP, India

The present study was aimed to investigate fish fauna of Gobind Sagar Reservoir Bundelkhand region district Lalitpur. Ichthyological study was conducted for twelve months (Feb. 2018-Mar. 2019). It was found to contain a total 29 species of fish fauna besides planktons, benthos and avian fauna. Various major carps, minor carps, cat fishes and weed fishes were identified. Endangered species like Notopterus chitala, Notopterus notopterus, Ompok bimaculatus and Eutropiichthys vacha were also observed.
