Mysidopsis gemina n. sp. (Crustacea: Mysida: Mysidae) from the northern Pacifc coast of Costa Rica
(2019-12-02)Mysidopsis gemina n. sp. is described from protected and exposed beach habitats in the provinces of Puntarenas and Guanacaste on the northern Pacifc coast of Costa Rica. Morphologically, M. gemina most closely resembles ... -
The mystery of how spiders extract food without masticating prey
(2006)Standard accounts of how spiders obtain food without masticating their prey are probably largely wrong. Species in the families Uloboridae, Thomisidae, Araneidae and Theridiidae do not inject digestive fluid into the prey’s ... -
Myxomycete assemblage turnover across a moisture and elevation gradient in Costa Rica
(2021-07-13)The formation of sporocarps in myxomycetes depends on environmental characteristics, among which, moisture and temperature seem to be relevant in tropical areas. Since temperature is linked to elevation, the effect of both ... -
Myxomycete colonization on translocated and non-translocated dead leaves from temperate and tropical forests
(2020-11)Samples of dead leaves on the forest floor were collected from a locality in central Costa Rica and another locality in northwest Arkansas in the United States and then were placed in fine-mesh nylon bags, autoclaved and ... -
Myxomycete diversity in Costa Rica
(2018-04)An updated analysis of myxomycete diversity in Costa Rica is provided herein as a product of an extensive data mining-based study intended to normalize the information on myxomycetes from that country. Within the context ... -
Myxomycete ecology along an elevation gradient on Cocos Island, Costa Rica
(2008)The marine biota of Cocos Island is well known; however, the terrestrial biota is poorly understood. In an effort to document the myxomycetes of the island and to determine their ecological distribution along an elevation ... -
Myxomycete ecology in urban areas: rapid assessment from two cities
(2021-02-25)Urban ecology has been an understudied topic in myxomycete research. For that reason, the present investigation aimed to generate data related to myxomycetes in urban areas of the Neotropical region. With an approach of ... -
Myxomycetes associated with bryophyte mats in San Ramón, Costa Rica
(2022)Myxomycete-bryophyte associations have been studied mostly in temperate regions of the world. Data from tropical regions are much more limited. The interesting landscape configuration of the San Ramón area in Costa Rica, ... -
Myxomycetes collected in the eastern United States and patterns of relative biodiversity
(2020-01-05)A total of 68 315 digitised records of myxomycetes from the eastern United States were compiled from all readily available sources. After cleaning the database for inconsistencies, 58 594 records remained that were ... -
Myxomycetes of Thailand
(2010)After the first report of myxomycetes from Thailand in 1902, there were only a few papers dealing specifically with these organisms over the following 85 years. In 2004, intensive ecological studies of myxomycetes began ... -
Myxomycetes within ecotones in temperate and tropical forests
(2021)Ecotones are interesting portions of forests where microorganisms can be studied for monitoring and diversity purposes. Given the faster life cycle of these organisms, their study in such a context is important to develop ... -
Natural History and Larval Behavior of the parasitoid Zatypota petronae (Hymenoptera: Ichneumonidae)
(2007)The koinobiont ectoparasitoid Zatypota petronae Gauld (Ichneumonidae) parasitizes medium-sized immatures of the cobweb spider Theridion evexum Keyserling (Theridiidae). Zatypota petronae apparently attacks the spider inside ... -
Natural history, courtship, feeding behaviour and parasites of Theridion evexum (Araneae: Theridiidae)
(2007)Theridion evexum constructs webs in the understory of wet middle-elevation forests in Costa Rica. The spiders construct retreats by curling a leaf and produce a mesh in front of the opening. Long, more or less vertical ... -
Near-neighbor tropical epiphytic orchids keep distinct mycorrhizal communities across their distribution in Costa Rica
(2022)Environmental and biotic axes act in combination to define the ecological niches of plant species. Two species with shared physical space are expected to compete for access to water and nutrients. In hyper-diverse areas ... -
Neither insects nor wind: ambophily in dioecious Chamaedorea palms (Arecaceae)
(2014)Pollination of Neotropical dioecious trees is commonly related to generalist insects. Similar data for non‐tree species with separated genders are inconclusive. Recent studies on pollination of dioecious Chamaedorea palms ... -
Neotropical Birds Respond Innately to Unfamiliar Acoustic Signals
(2022)Many animals respond to heterospecific signals that indicate the presence of food or predators. Although the benefits of responding are clear, the behavioral and cognitive mechanisms underlying responses are not. Whether ... -
Neotropical flowering epiphyte diversity: local composition and geographic affinities
(2013)Worldwide, the highest diversity of vascular epiphytic plants resides in the Neotropics. The general pattern of taxonomic composition of the neotropical epiphytic flora has been described, but information regarding the ... -
Neotropical freshwater crabs (Decapoda: Pseudothelphusidae) shred leaves
(2020)Freshwater crabs are macroconsumers that are commonly found in Neotropical headwater streams that may play a key role in energy flow and nutrient cycling in detrital food webs. Although studies have examined the feeding ... -
Nephila clavipes spiders (Araneae: Nephilidae) keep track of captured prey counts: testing for a sense of numerosity in an orb-weaver
(Animal Cognition DOI 10.1007/s10071-014-0801-9, 2014-08-28)Nephila clavipes golden orb-web spiders accumulate prey larders on their webs and search for them if they are removed from their web. Spiders that lose larger larders (i.e., spiders that lose larders consisting of more ... -
Nest and eggs of the southern Central American endemic Tawny-chested Flycatcher Aphanotriccus capitalis
(2017)The Aphanotriccus, Lathrotriccus and Cnemotriccus clade (Cicero & Johnson 2002, Ohlson et al. 2008, Tello et al. 2009) comprises five species of tyrant flycatcher that inhabit dense second growth, disturbed forest, riverine ...
