Abstract: Invasive alien species have affected every ecosystem type on the planet and are considered as the second greatest global threat to biodiversity, following habitat destruction. Therefore, the objective of this study was to identify the major dominant species, awareness creation local to community, invaded land uses types and management procedure taken to control and reduce invading species in Buno Bedelle zone, Southwest Ethiopia. As stated by, an assessment was accomplished in Buno Bedelle zone, Dedessa, Dedelle and Chora districts, in 41 randomly selected households in twelve distnict Kebeles (the smallest administrative unit in Ethiopia). According to the interview and field observation, the level of invasive alien plant species invasion was very high and the plant was the most dominant on cultivated lands, grazing lands, roadside and non-cultivated land in the study areas. Invasive alien plant species were appear to the study area during road construction cooperatively with sand, stones and agricultural inputs and materials. The great threat and problem were loss of biodiversity and crop production due to high outspread rate, prolific seed production and high rejuvenate capacity of invasive alien plants. The implication of the study candidates regarding the finest method that the local people should use to manage the spread of IAPS, 94% of them indicated that the control of the spread in the future went further research by stakeholder and most of them believed the government, communities and non-governmental organizations should work together in order to control the spread of Invasive alien plant species. Researchers overwhelming need to distinguish and measure the socioeconomic effects and devise proper strategies for cost effective and time efficient management options of invasive alien species.

Abstract: In June 2017, we documented the first observed spawning event by a reintroduced population of Lake Sturgeon (Acipenser fulvescens) in Fall Creek, a tributary to Cayuga Lake, New York, USA. This is the first observed spawning encounter of adult Lake Sturgeon since the beginning of the multi-agency Lake Sturgeon restoration effort in Cayuga Lake initiated in 1995 by the New York State Department of Environmental Conservation. Lake Sturgeon egg deposition was found specifically on substrate mainly composed of gravel sized rocks with depths and flows that made up a unique microhabitat combination within the creek which is not typical of habitat identified in other Lake Sturgeon spawning habitat studies across the Great Lakes. An estimated 810,052 ± 24,386 eggs were deposited in the sampled area of Fall Creek. The identified, potentially productive spawning microhabitat type in Fall Creek is likely to be widespread in similar tributaries around Cayuga Lake as well as small tributaries to other Finger Lakes and Lake Ontario. Ongoing research is focused on the evaluation of the extent of Finger Lakes habitat similar to that identified in Fall Creek. This microhabitat evaluation of sturgeon spawning and the broad scale landscape knowledge of tributary habitats, should support subsequent management to restore Lake Sturgeon.

Abstract: Tehsil Pakpattan is situated in the Doab region of Punjab, Pakistan, along the Sutlej River. The aim of the present study was to evaluate the avian biodiversity of Tehsil Pakpattan. The study included the evaluation of species diversity, IUCN Red List status, migratory description, and feeding habits of the bird populations of Tehsil Pakpattan. Regular surveys were conducted at 10 different localities in Tehsil Pakpattan, including Islam Colony, Kanipur, Farid Kot, 14 S/P, Chak Khagga, Musewal, 8 S/P, Noorpur, Green Town, and Bonga Niaz Khan, from January 2022 to April 2023. The Shannon‒Wiener diversity index value (R’ = 3.41) indicated the notable diversity of the bird populations in the study area. A total of 1884 individuals representing 41 species, 30 families, and 12 orders were recorded. The highest diversity was in the order Passeriformes. The most common birds in the observed population were cattle egrets (n = 160), house crows (n = 150), Asian green bee eaters (n = 100), rock pigeons (n=100), brown rock chats (n = 98) and house sparrows (n = 90). Among all the species, 34 were residents, 2 were summer breeders, and one was a winter visitor. Thirty-seven (75.60%) of the bird species belonged to the least concern (LC), 2 (4.87%) were nearly threatened (NT), and 2 (4.84%) were vulnerable (VU) categories of the IUCN Red List.

Abstract: The re-introduction of native species that have been extirpated or in low abundance in the Great Lakes has been a binational initiative between the United States and Canadian governments. Recently, new management programs have been underway that use current hatchery facilities for the restoration of native forage fishes in Lake Ontario. These species include Bloater (Coregonus hoyi), which has been extirpated from Lake Ontario for approximately four decades, and Cisco (C. artedi), which exists at a fraction of its former abundance. We assessed morphometrics, length-weight relationships, and condition factors during early life development for eight cohorts of Cisco and Bloater reared from 2012-2019. Weekly samples for Cisco and Bloater were measured from hatch until release (29-45 weeks, 133-1,002 samples annually). Head width, gape, mandible length, and mouth height metrics were all larger for Cisco than Bloater at any given size but increased at similar rates for both species. Average condition factors for Cisco and Bloater were 0.54317 and 0.55892, respectively. This information may also improve field identification of these species, helping managers evaluate the relative success of different release strategies for rehabilitation of populations of these native species.
