A review of discoveries of plants and animals by a 1978 expedition from Louisiana State University to Peru is presented. Genesis of this study was owing to the senior author’s observation of unusually high species richness in Araceae among a collection of plants made in northern Peru. A subsequent review showed that the region was rich in many ways. Determinations to date include 983 species belonging to 513 genera and 145 families of which 81 species are endemic. Included are 59 plant taxa new to science described elsewhere. Eleven aroids (Araceae) from northern Peru are described and illustrated as new. Some records represent new taxa described from voucher specimens independently collected by botanists at prior or later dates and different localities. A collection was assigned the nov. sp. category of noteworthiness if Tropicos database (http://www.tropicos.org) showed either the Alwyn H. Gentry, et al. and or the Philip J. Barbour accession to be the first such collection known. Specimen searches in Tropicos by senior collector as Philip Barbour and separately by Gentry and constrained by appropriate dates revealed 1687 independent determined voucher specimens of which 1545 are noteworthy (92%) by the designated categories. Noteworthy categories are described and presented in appendices 2 and 3. Extralimital plant distribution records are not described here. Four new bird species/subspecies and seven new frog species were discovered on this expedition. It is important to note that after only 42 years much of the region where many of these discoveries were made is now largely devoid of natural vegetation. Appendix 4 provides detailed descriptions of habitat on Cerro Colán as recent as 2017. This study is a reminder that areas newly opened for exploration should be thoroughly and quickly studied to capture the greatest scientific benefit. It shows how much could be attained in a small span of time by a small but dedicated group of biologists.

OUR attention has been called to two corrections which should be made in the letter of Dr. Thomas O. Gamble as it appeared in this column in the September issue of Pediatrics Dr. Gamble writes: "On page 365 I quoted the first objective of the Association of American Physicians and Surgeons. Quotation marks should have been placed at the end of the two sentences which are enclosed in parentheses. Anyone reading my letter might assume that the last two sentences represented my interpretation of the first objective. So, while I agree entirely with the objective and its interpretation, I should not be given credit for something which belongs to the A.A.P.S." The second correction is made in the letter from Dr. William J. Orr, Buffalo, New York, which is published below. Dr. Myron E. Wegman and Dr. Ralph V. Platou, Professor and Head, Department of Pediatrics, respectively of Louisiana State University of Medicine and Tulane University School of Medicine have polled the professors of pediatrics throughout the country to ascertain their experience with federal funds. The results of this survey are summarized in their letter.

We examined the avifauna of Saurashtra University Campus (SUC), Rajkot, Gujarat from July to December 2017.  The study area was divided into four sections: North (N), East (E), South (S) and West (W) and surveyed over 18 visits (four line transects/visit).  We recorded a total of 82 bird species from 67 genera, 40 families and 16 orders.  Of these 57 species were terrestrial and 25 aquatic.  By population size the most abundant birds were members of Columbidae (28%), Sturnidae (13%), and Charadridae (8%).  Seventy per cent of birds observed (n=7665) were classed as very common and 2% (n=261) as very rare.  Species density (S/N = 3.39) and population density (n/N = 196) were at their maximum in December.  Ecological indices on temporal base reveal high species richness and Simpson diversity (1/D =17.0 and 1-D= 0.942) in August and November and Shannon diversity was high (H’=3.275) in November during study period.

Siberut Island, Mt. Talamau, Rimbo Panti Nature Reserve, and intervening locations in West Sumatra Province were visited during two expeditions in 2018-2019 by ornithologists from the Museum Zoologicum Bogoriense (MZB) - Indonesian Institute of Sciences (LIPI), Louisiana State University Museum of Natural Science (LSUMNS), and Andalas University. The main objective of these expeditions was to obtain data and tissue-subsample rich museum specimens for morphological and genetic studies of phylogeny and population genetics of Southeast Asian birds aimed at understanding the causes of avian diversification in the region. We also observed, photographed, and audio-recorded numerous bird species during the expeditions and archived these data. In total, 285 species were identified, and specimen material was collected from 13 species and 26 subspecies not previously represented in tissue resource collections. Here, we provide complete lists of birds found at each location, highlight distributional discoveries, and note cases of potential taxonomic, ecological, and conservation interest.

Variation in bird assemblages associated with forest clearing and urbanisation in the greater Brisbane area was assessed by counting birds in sites within six habitat categories: large remnants, small remnants, no- understorey remnants, canopy suburbs (original trees present), planted suburbs, and bare suburbs. Total bird abundance and species richness were generally highest in canopy suburbs. Individual species showed many significant abundance differences among the habitat types, and were classified into three major response categories: bushland species (3 in summer, 13 in winter), tolerant species (13 in summer, 13 in winter), and suburban species (12 in summer, 11 in winter). The commonly proposed notion that urbanisation results in lowered bird species richness and increases in introduced species is broadly consistent with the observed differences between bare suburbs and large remnants. However, it does not adequately describe the situation in the planted and canopy suburbs, where there was high species richness and extremely high abundance of some native species (including noisy miners, lorikeets, friarbirds, and butcherbirds) but low abundance of a majority of the species common in the original habitats (including fantails, wrens, whistlers, and other small insectivores). Retained forest remnants are essential for the latter group. Urban plantings of prolifically flowering native species do not reverse the effects of deforestation, but promote a distinctive group of common native suburban bird species. Origins of the urban bird assemblage are discussed.

AVIFAUNA OF THE SACRED SOIL OF GUARAPIRANGA (SÃO PAULO, BRAZIL): The avifauna of São Paulo, the largest Brazilian city, is one of the most studied in Brazil. However, some areas are lacking basic studies on the avifauna, including those under intense pressure from urban growth and deforestation. Here we present a list of bird species occurring in the Solo Sagrado do Guarapiranga (23°45’00”S, 46°44’00”W), an urban park in southern São Paulo. We carried out monthly bird surveys from July 2008 to June 2009, using transect method. After 250 hours of observations, we recorded 180 species, including 31 species endemics to Atlantic Forest and two species that are globally threatened. The insectivorous, omnivorous and frugivorous species were the most represented feeding guilds, with 70, 39 and 21 species, respectively. Occasional and rare species composed the community majority. The high species richness and the presence of threatened species indicate the importance of the area to the bird’s conservation in the largest Brazilian city.

ContextThe negative association between elevation and species richness is a well-recognized pattern in macro-ecology. ObjectivesThe aim of this study was to investigate changes in functional evenness of breeding bird communities along an elevation gradient in Europe. MethodsUsing the bird data from the EBCC Atlas of European Breeding Birds we estimated an index of functional evenness which can be assumed as a measure of the potential resilience of communities.ResultsOur findings confirm the existence of a negative association between elevation and bird species richness in all European eco regions. However, we also explored a novel aspect of this relationship, important for conservation: Our findings provide evidence at large spatial scale of a negative association between the functional evenness (potential community resilience) and elevation, independent of the eco region. We also found that the Natura2000 protected areas covers the territory most in need of protection, those characterized by bird communities with low potential resilience, in hilly and mountainous areas.ConclusionsThese results draw attention to European areas occupied by bird communities characterized by a potential lower capacity to respond to strong ecological changes, and, therefore, potentially more exposed to risks for conservation.
