Check List 4(2): 152–158, 2008. ISSN: 1809-127X LISTS OF SPECIES Mammals, Birds and Reptiles in Balbina reservoir, state of Amazonas, Brazil. Márcia Munick Mendes Cabral Gália Ely de Mattos Fernando César Weber Rosas Instituto Nacional de Pesquisas da Amazônia (INPA). Laboratório de Mamíferos Aquáticos. Caixa Postal 478. CEP 69011-970, Manaus, AM, Brazil. E-mail: [email protected] Abstract: The construction of hydroelectric power stations can affect the fauna, including the adaptation to the new lentic conditions, and may lead to the disappearance of some species and the colonization of others. Usually, there is a lack of information in the post-flooding phases. The present study is a preliminary qualitative survey of mammals, birds, and reptiles in the influenced area of the Balbina hydroelectric dam (01º55' S, 59º29' W). Species records were made during field trips to the reservoir with no group specific methods. The conservation status of the identified species followed the classification adopted by IUCN. Twenty-two mammals (one endangered – EN), forty-two birds and six reptiles (one vulnerable – VU) were identified. Although the list presented here is preliminary, if appropriately complemented it can be used to understand the effects of hydroelectric dams on the Amazonian fauna.

We analyzed vocal divergence between two hybridizing 14 species of sex-role reversed polyandrous shorebirds, the Northern Jacana (Jacana 15 spinosa) and Wattled Jacana (Jacana jacana). We found that J. spinosa calls have higher peak 16 frequency and fundamental frequency than J. jacana calls. We also compared calls 17 between males and females, as both jacana species are sex-role reversed and females compete for 18 male mates. Males produce calls with a higher peak frequency, exhibit shorter note lengths and 19 emit a greater number of notes within a calling bout than females, which could relate to mate 20 attraction. These results suggest that vocal divergence could act as a behavioral barrier to limit 21 hybridization between the species and vocalizations may function differently between male and 22 female jacanas. -
21 Sep 2018 Lists of Victims and Hosts of the Parasitic
version: 21 Sep 2018 Lists of victims and hosts of the parasitic cowbirds (Molothrus). Peter E. Lowther, Field Museum Brood parasitism is an awkward term to describe an interaction between two species in which, as in predator-prey relationships, one species gains at the expense of the other. Brood parasites "prey" upon parental care. Victimized species usually have reduced breeding success, partly because of the additional cost of caring for alien eggs and young, and partly because of the behavior of brood parasites (both adults and young) which may directly and adversely affect the survival of the victim's own eggs or young. About 1% of all bird species, among 7 families, are brood parasites. The 5 species of brood parasitic “cowbirds” are currently all treated as members of the genus Molothrus. Host selection is an active process. Not all species co-occurring with brood parasites are equally likely to be selected nor are they of equal quality as hosts. Rather, to varying degrees, brood parasites are specialized for certain categories of hosts. Brood parasites may rely on a single host species to rear their young or may distribute their eggs among many species, seemingly without regard to any characteristics of potential hosts. Lists of species are not the best means to describe interactions between a brood parasitic species and its hosts. Such lists do not necessarily reflect the taxonomy used by the brood parasites themselves nor do they accurately reflect the complex interactions within bird communities (see Ortega 1998: 183-184). Host lists do, however, offer some insight into the process of host selection and do emphasize the wide variety of features than can impact on host selection. -
Southeast Brazil: Atlantic Rainforest and Savanna, Oct-Nov 2016
Tropical Birding Trip Report Southeast Brazil: Atlantic Rainforest and Savanna, Oct-Nov 2016 SOUTHEAST BRAZIL: Atlantic Rainforest and Savanna October 20th – November 8th, 2016 TOUR LEADER: Nick Athanas Report and photos by Nick Athanas Helmeted Woodpecker - one of our most memorable sightings of the tour It had been a couple of years since I last guided this tour, and I had forgotten how much fun it could be. We covered a lot of ground and visited a great series of parks, lodges, and reserves, racking up a respectable group list of 459 bird species seen as well as some nice mammals. There was a lot of rain in the area, but we had to consider ourselves fortunate that the rainiest days seemed to coincide with our long travel days, so it really didn’t cost us too much in the way of birds. My personal trip favorite sighting was our amazing and prolonged encounter with a rare Helmeted Woodpecker! Others of note included extreme close-ups of Spot-winged Wood-Quail, a surprise Sungrebe, multiple White-necked Hawks, Long-trained Nightjar, 31 species of antbirds, scope views of Variegated Antpitta, a point-blank Spotted Bamboowren, tons of colorful hummers and tanagers, TWO Maned Wolves at the same time, and Giant Anteater. This report is a bit light on text and a bit heavy of photos, mainly due to my insane schedule lately where I have hardly had any time at home, but all photos are from the tour. www.tropicalbirding.com +1-409-515-9110 [email protected] Tropical Birding Trip Report Southeast Brazil: Atlantic Rainforest and Savanna, Oct-Nov 2016 The trip started in the city of Curitiba. -

He argued that these traits had evolved either through Initial acceptance 25 May 2008 intrasexual competition between males to monopolize access to females or through consistent female Final acceptance 27 August 2008 preferences for mating with superior partners. Since 1871, a substantial body of research has confirmed Published online 31 October 2008 his explanation of the evolution of secondary sexual characters in males, although sex differences in MS. number: 08-00267 reproductive behaviour are more diverse and the evolutionary mechanisms responsible for them are more complex than was initially recognized. However, secondary sexual characters are also widespread Keywords: in females but, as yet, their evolution and distribution have received relatively little attention from gender differences evolutionary biologists. Here, I suggest that the mechanisms responsible for the evolution of secondary intrasexual competition sexual characters in females are similar to those operating in males and include intrasexual competition mate choice sex roles between females for breeding opportunities, male mating preferences and female competition to attract sexual selection mates. Unlike males, females often compete more intensely for resources necessary for successful reproduction than for access to mating partners and the development of secondary sexual characters in females may be limited by costs to fecundity rather than to survival. -
