Geodesics without conjugate points and curvatures at infinity
Anais da Academia Brasileira de Ciências, 2000 We study the asymptotic behavior of curvature and prove that the integral of curvature along a geodesic without conjugate points is nonpositive and some generalizations of Myers theorem and Cohn-Vossen's theorem. Some applications are also given.

Wildlife Biology, EarlyView.Predation by pine martens Martes martes and red foxes Vulpes vulpes is an important factor influencing the population dynamics of capercaillie Tetrao urogallus. However, there is a knowledge gap regarding the relative effects of these mesopredators on the reproductive success of capercaillie. To better understand how various landscape factors influence

Predicting the breeding distribution of wader species across climatic and environmental gradients
Wildlife Biology, EarlyView.Developing and applying species distribution models is particularly urgent for species currently facing high levels of environmental change. Waders (Charadrii) are among the most species‐rich groups of birds breeding at higher latitudes and the one where species are declining fastest. Iceland holds a large part of the global population of several wader

Some Properties of Geodesic Strongly E-b-vex Functions
International Journal of Analysis and Applications, 2019 Geodesic E-b-vex sets and geodesic E-b-vex functions on a Riemannian manifold are extended to the so called geodesic strongly E-b-vex sets and geodesic strongly E-b-vex functions. Some basic properties of geodesic strongly E-b-vex sets are also studied.

THE UPPER OPEN GEODETIC NUMBER OF A GRAPH [PDF]
Zbornik Radova Ekonomskog Fakulteta u Istočnom Sarajevu, 2012 For a connected graph G of ordern, a set S of vertices of G is a geodetic set of G ifeach vertex n of G lies on a x-y geodesic for someelements x and y in S.

Missouri Botanical Garden's cycad collection: A journey through time
Plant Species Biology, EarlyView.This article summarizes the history of the Missouri Botanical Garden's extensive cycad collection. Some of the specimens currently housed in the living collections date back well over 100 years. Cycads continue to face a myriad of threats in the wild, and their conservation in ex situ collections is of critical importance to assist in their survival ...
