Abstract Time-series data offer a way of investigating the causes driving ecological processes as phenomena. To test for possible differences in water relations between species of different forest structural guilds at Danum (Sabah, NE Borneo), daily stem girth increments (gthi), of 18 trees across six species were regressed individually on soil moisture potential (SMP) and temperature (TEMP), accounting for temporal autocorrelation (in GLS-arima models), and compared between a wet and a dry pe...

Abstract Mnesicleinae is a little-known subfamily of Chorotypidae and consists of 19 genera distributed throughout the Malay Archipelago, including Uvarovia Bolívar, 1930. For many species from this subfamily, nearly nothing is known after their original descriptions. Based on new materials from recent surveys, we were able to examine specimens from two species: Uvarovia longipennis Bolívar, 1930 from Malay Peninsula (also type species for genus) and Uvarovia gracilipes Bolívar, 1931 from Bor...

Edwards, Impacts of tropical selective logging on local-scale movements of understory birds, Biological Conservation, Volume 264, 2021, 109374, ISSN 0006-3207

Abstract Widespread selective logging in tropical forest causes structural damage and associated shifts in species composition, but we lack understanding of how selective logging impacts mechanistic processes that drive these biodiversity changes. Movement is a vital mechanistic process underpinning demographic, ecological, and evolutionary processes that likely determine species responses to logging. We assessed how tropical selective logging impacts local movements of 71 understory avian spec...

Abstract. Liana dynamics may influence tree dynamics and vice versa. Only long-term studies can perhaps disentangle them. In two permanent plots of lowland dipterocarp forest at Danum, a liana census in 1988 was repeated in 2018. The primary forest was still in a late stage of recovery from an inferred large and natural disturbance in the past. Mean number of lianas per tree decreased by 22% and 34% in plots 1 and 2, and in different ways. By 2018, there were relatively more trees with few liana...

Including tree spatial extension in the evaluation of neighborhood competition effects in Bornean rain forest

Including tree spatial extension in the evaluation of neighborhood competition effects in Bornean rain forest

article: Newbery DM, Stoll P. Including tree spatial extension in the evaluation of neighborhood competition effects in Bornean rain forest. Ecol Evol. 2021;11:6195–6222.

Abstract Classical tree neighborhood models use size variables acting at point distances. In a new approach here, trees were spatially extended as a function of their crown sizes, represented impressionistically as points within crown areas. Extension was accompanied by plasticity in the form of crown removal or relocation under the overlap of taller trees. Root systems were supposedly extended in a similar manner. For the 38 most abundant species in the focal size class (10–
