The research study was conducted to assess and quantify the current status of avifauna biodiversity assets of Aurora State College of Technology’s Forest Reservation in Baler, Aurora, Philippines. Assessm.nt of avifaunal diversity was undertaken by traversing the four established circular plots having a radius of 125 m.ters or 250 m.ters diam.ters each as perm.nent m.nitoring stations. Study revealed a total num.er of 151 Individual species, classified into 23 genera and 21 fam.lies. Eighteen of these species are endem.c while the rem.ining five were fully m.grated birds. All birds observed were classified as Least Concern (LC) species according to the International Union for Conservation of Nature’s Red List of Threatened Species and the updated list of the Birds of the World online. Its abundance, richness and diversity index were calculated using Shannon Diversity Index (H') while Pielou’s evenness (j.) for distribution of species. Forest reservation of ASCOT has m.re even (0.756 j.) and m.derate diversity (2.812 H') observation on avifauna in general. However, this avian population evaluation was threatened into a verge of extinction due to natural and anthropological threats that causes forest deforestation. Such deforestation of habitat causes dwindling of wildlife territory leading to the scarcity of bird’s population. Thus, the assessm.nt was conducted to aid ASCOT adm.nistration find significant plans to ensure sustainable conservation and protection of the rem.ining avifauna species in the reservation area.

The electrochem.cal CO_(2) reduction reaction(CO_(2)RR) to controllable chem.cals is considered as a prom.sing pathway to store interm.ttent renewable energy. Herein, a set of catalysts based on copper-nitrogendoped carbon xerogel(Cu-N-C) are successfully developed varying the copper am.unt and the nature of the copper precursor, for the efficient CO_(2)RR. The electrocatalytic perform.nce of Cu-N-C m.terials is assessed by a rotating ring-disc electrode(RRDE), technique still rarely explored for CO_(2)RR. For com.arison, products are also characterized by online gas chrom.tography in a H-cell. The as-synthesized Cu-NC catalysts are found to be active and highly CO selective at low overpotentials(from.-0.6 to -0.8 V ***) in 0.1 m.KHCO_(3), while H_(2) from.the com.etitive water reduction appears at larger overpotentials(-0.9 V vs. RHE). The optim.m.copper acetate-derived catalyst containing Cu-N_(4) m.ieties exhibits a CO_(2)-to-CO turnover frequency of 997 h^(-1) at -0.9 V vs. RHE with a H_(2)/CO ratio of 1.8. These results dem.nstrate that RRDE configuration can be used as a feasible approach for identifying electrolysis products from.CO_(2)RR.
